A December job in Andover, second day of a three to five day exterior. Wash and prep done, first coat going on the south elevation.
It was the kind of December afternoon the Bluegrass gets more often than people admit. Sixty degrees, wind out of the south, everything damp.
Around two o’clock the phone started buzzing with a watch box that covered most of central Kentucky.
Here is the thing worth understanding about that moment. A watch is not a warning, and nothing is happening yet. What matters is what gets done in the next forty minutes, while there is still time to move a ladder safely.
This page covers what should happen on a job site when that box appears, what happens to coating that went on this morning, and who absorbs the two days.
What happens to your exterior project when a tornado watch is issued?
Spray application stops. The site gets secured against wind, meaning ladders down, staging struck, pails lidded and moved, and masking either taped tight or pulled entirely. The crew photographs every elevation with a time stamp, then leaves well before the weather arrives. The schedule is rebuilt afterwards, once the substrate is verified dry with a meter rather than by eye.
Why a watch and not a warning is the trigger
Because a warning means take shelter now.
By the time a warning is issued for your area, nobody should be carrying a 32 foot ladder across a lawn or coiling hose in a driveway. That is exactly the wrong activity for that moment.
A watch gives you hours. A warning gives you minutes. Anything that has to be moved gets moved on the watch.
For the household this is usually not an emergency at all. For the job site it is a stop-work trigger, and those two things are not in conflict.
What is the difference between a tornado watch and a tornado warning?
Worth getting straight, because people use them interchangeably and they mean very different things.
| Tornado watch | Tornado warning | |
| What it means | Tornadoes are possible in and near the watch area | A tornado has been sighted or indicated by radar |
| Who issues it | The Storm Prediction Center | Your local National Weather Service forecast office |
| Area covered | Large, multi-county | Roughly city sized |
| What you do | Prepare and stay aware | Take shelter immediately |
A watch means conditions are favourable. A warning means it is happening, with imminent danger to life and property.
How long a watch lasts and how big it is
A typical watch covers about 25,000 square miles, roughly half the size of Iowa, and outlines an area where organized severe weather is expected over a two to eight hour period.
That scale matters for a homeowner watching one appear on a phone. A watch box over central Kentucky does not mean anything is coming to your street. It means somewhere in a very large area, conditions support it.
What Particularly Dangerous Situation wording means
The Storm Prediction Center adds that phrasing when long-lived intense tornadoes are likely.
It is not routine language and it is not used lightly. If it appears on a watch covering your county, treat the afternoon differently.
Why a severe thunderstorm watch matters just as much to a job site
This one gets ignored and it should not.
Straight-line wind and hail wreck staging, tear masking and mark fresh coating without any tornado being involved at all. From a job site perspective, a severe thunderstorm watch with damaging wind gusts in the outlook calls for the same shutdown as a tornado watch does.
Do tornadoes really happen in Kentucky in December?
Yes, and the record is longer than most people assume.
The National Weather Service Louisville office records 9 December tornadoes in its county warning area since 1865. Three of those fell on a single day, December 21, 2013, all rated EF1, in Taylor, Harrison and Bourbon counties.
Bourbon County borders Fayette County. That is the one that makes this a Lexington subject rather than a general interest one.
The same office records more than 70 winter tornadoes, December through February, in its warning area between 1865 and 2021.
What December 10 to 11, 2021 established
According to the National Weather Service Paducah office, a single EF-4 tornado tracked 165.7 miles across 11 western Kentucky counties from 8:49 to 11:47 PM CST, with estimated peak winds of 190 mph.
It was the ninth longest tornado path ever recorded in the United States and the deadliest December tornado in US history. Fifty seven people in Kentucky died in that tornado.
That is the record, stated plainly. It is not an argument for anything and we are not going to use it as one.
What December 9, 2023 added
Three more tornadoes in the NWS Louisville warning area, all in early December and all in daylight.
An EF-2 in Logan and Simpson counties with 115 mph peak winds at 2:15 PM CST, and EF-1s in Warren and Monroe counties.
Daylight matters operationally. That is a working afternoon, with crews on ladders.
Why the Bluegrass gets warm December severe weather
This is the part that surprises people who assume winter means cold.
Lexington December normals run a 45.9 degree high over a 29.6 degree low, with 4.20 inches of precipitation. A December severe weather day here is usually warm, humid and driven by southerly flow, not by a cold outbreak.
Which is precisely why it catches exterior crews. Those are the same conditions that make a December day workable in the first place.
What should the crew do before they leave the site?
This is the checklist worth holding any contractor to, in order.
Shut down and depressurise the sprayers. Lines relieved, not just switched off.
Lid and move coating pails and solvents indoors or into a locked trailer.
Pull or fully tape masking. Never leave it loose.
Take ladders down and lay them flat.
Strike scaffolding and staging.
Coil and stow hoses and cords.
Remove or weight loose plywood, sheet goods and trim stock. These become projectiles.
Move vehicles and equipment under cover if hail is in the outlook.
Photograph every elevation with a time stamp.
Give the homeowner a named contact and a restart plan before leaving.
That last one is the one homeowners actually remember, and it is free.
Why loose masking is the single worst thing to leave
Because it does not simply blow away. It tears, wraps around trim and gutters, and drags its own tape, fasteners and grit across coating that has not fully cured.
A crew that leaves plastic flapping on a house before a wind event has created a problem that did not exist that morning. Pull it or tape it down. There is no third option.
What gets covered and what does not
Temporary coverings over finished work are standard practice on construction sites, and Travelers Risk Control publishes similar guidance for commercial sites: secure loose materials, remove projectiles, and cover finished work.
The caveat matters more than the rule. A tarp that can lift is worse than no tarp, because it becomes both a sail and an abrasive. If it cannot be secured properly, it should not be there.
What should you do as the homeowner?
Six things, none of which take long.
Clear the yard of anything the crew did not stage
Bring in patio furniture, planters and anything loose
Park away from the work zone, and under cover if hail is possible
Close windows on the elevation being coated
Know where your shelter is, and check it is clear
Take your own photos of the exterior before the weather arrives
That last one costs two minutes and settles any question later about what condition the work was in.
Does wind and rain ruin coating that is already on the house?
Separate the two cases, because they are not the same.
Fully cured coating is not at risk from a normal storm. Wind and rain are what an exterior finish exists for.
Coating applied within the last few hours is at risk. Exterior finishes generally need around four hours before they will take a light shower without marking, and surface temperature has to stay above the dew point by a margin during application and cure.
So the question is not whether it rained. It is what time the last pass went on.
What rain damage actually looks like
Four signatures, and they show up within days.
Surfactant leaching, tan or brown streaking that feels slightly sticky. Film disruption, where running water physically thinned the coating. Blistering, from moisture trapped under the film. Texture change, where the surface reads differently at a low angle.
None of those are guesses. They are visible and diagnosable, which is why the time-stamped photos matter.
What happens between coats
The second coat waits until the substrate is verified, not until it looks dry.
This is where schedules slip in ways homeowners find frustrating and crews find unavoidable. A wall can look completely dry on the surface while still holding water in the substrate, particularly on wood siding after a soaking rain.
How the crew verifies before restarting
With a moisture meter, not with a hand and an opinion.
The common trade target on wood is around 15 percent moisture content or lower before work resumes. Ask what standard your contractor uses and ask them to show you the reading. A crew that will show you the meter is a crew that took a reading.
Why do we stop spraying before the weather is even close?
There is a second reason beyond safety, and it is about the finish itself.
Airless spray is manageable in light air, roughly under 10 mph. Above that, three things start happening at once. Drift increases, so material goes where it is not wanted. Dry spray becomes a problem, where the material partially dries in the air and lands rough. And film build goes uneven across the elevation.
There is also a liability dimension. Overspray drift onto a neighbour’s car, windows or siding is a real cost and a real conversation, and gusty conditions ahead of a storm line are exactly when it happens.
So a crew packing up as the sky changes is not being cautious about the weather alone. They are protecting the finish you are paying for.
Who pays for a weather delay, and how does the schedule get rebuilt?
The honest answer, written for a homeowner rather than a contracts lawyer.
In construction generally, weather delay is treated as excusable but not compensable. That means the contractor gets additional time, and neither party gets extra money. Nobody is owed anything for a lost Tuesday.
“Unusually severe weather” is tested against a 5 to 10 year National Weather Service average for that specific location, not against how bad the day felt. A December storm in Kentucky is not unusual by that measure.
On a residential job the practical consequence is simple. The price does not move because of two lost days. The finish date does.
What to ask before you sign
Three questions, at estimate stage rather than mid-storm:
Does the contract have a weather clause, and what does it say?
How is restart priority decided when several jobs are delayed at once?
Who is responsible for materials and equipment left on site?
Ask them in that order and get the answers in writing. Any contractor who has thought about this has answers ready.
How the schedule gets rebuilt
Not from where the sprayer stopped.
A restart works forward from the prep stage, because a delay usually means re-checking and sometimes redoing preparation on the affected elevations. Washing off what blew onto a wall is part of the restart, not an extra.
That is slower than a homeowner expects and it is the difference between a finish that lasts and one that gets blamed on the product in three years.
What a December shutdown looked like on a Lexington job
Back to Andover.
In the forty minutes after that watch box appeared, the sprayers were shut down and the lines relieved. Pails were lidded and moved into the garage with the homeowner’s permission. Masking was either taped down tight or pulled entirely rather than left to catch wind.
Ladders came down and went flat on the ground. Staging was struck. Hoses were coiled and stowed. The whole elevation was photographed with the time stamp on.
Then the crew lead walked the homeowner through exactly where the coating stood, gave her a name and a number, and left.
Nothing happened. The line went south of us and the watch expired that evening. We were back at eight the next morning.
That is the point worth making. The work you do for the storm that misses is the same work that saves the job when one does not.
Does any of this change what you should have on your house?
Being clear about the limit first. No coating is a wind-rated product, ours included, and nothing on this page suggests otherwise. A finish does not protect a house from severe weather and anyone implying it does is selling you something that does not exist.
What a finish does affect is the ordinary aftermath. Driving rain week after week, debris scuffing, grit, and repeated freeze-thaw cycling through a Kentucky winter.
Our coating is applied as two airless sprayed coats, never rolled, at roughly 80 percent solids with ceramic microspheres, 8 to 10 times the thickness of paint, and it carries a 25 year transferable warranty against a typical 5 to 7 year paint life. That is a durability argument about weathering, not a storm protection claim.
Materials and elevations most exposed in the Bluegrass
West and south elevations take the most of it, since that is where our weather comes from. Open horse farm properties out toward Nicholasville, Georgetown, Versailles and Richmond get it worst, because there is no windbreak at all.
Hardie board, stucco, wood siding, brick, vinyl, aluminum and metal siding each weather differently and each need a different preparation approach.

Frequently asked questions
What is the difference between a tornado watch and a tornado warning? A watch means tornadoes are possible in and near the watch area, and it is issued by the Storm Prediction Center over a large multi-county box. A warning means a tornado has been sighted or indicated by radar, is issued by your local forecast office over roughly a city-sized area, and means take shelter immediately.
How long does a tornado watch last? A watch typically covers a two to eight hour period and spans about 25,000 square miles, roughly half the size of Iowa. That scale is why a watch over central Kentucky does not mean anything is heading for your street. It means conditions across a large region support organized severe weather.
Do tornadoes really happen in Kentucky in December? Yes. The NWS Louisville office records 9 December tornadoes in its warning area since 1865, three of them on December 21, 2013 in Taylor, Harrison and Bourbon counties, and more than 70 winter tornadoes between 1865 and 2021. December 9, 2023 produced three more, all in daylight in early December.
Will a storm ruin exterior coating that was applied this morning? It depends on the hours. Fully cured coating handles ordinary weather without difficulty. Coating applied within the last few hours can be marked, since exterior finishes generally need around four hours before taking even a light shower. Damage shows as surfactant streaking, film thinning, blistering or texture change, and it is diagnosable.
How soon after rain can an exterior crew start again? When the substrate is verified dry with a moisture meter, not when the wall looks dry. The common trade target on wood is around 15 percent moisture content or lower. After a soaking rain, wood siding and stucco can hold moisture for a day or more even under sunshine, so appearance is not a reliable guide.
Who pays for weather delays on a home exterior project? Generally nobody pays extra. Weather delay in construction is usually excusable but not compensable, meaning the contractor gets additional time while neither party gets more money. “Unusually severe weather” is measured against a 5 to 10 year National Weather Service average for the location. Check your own contract’s weather clause.
Should I move my car and patio furniture? Yes, and it takes five minutes. Move vehicles away from the work zone and under cover if hail is in the outlook, since staging and materials sit close to the house. Bring in patio furniture, planters and anything loose, because those become projectiles in straight-line wind just as readily as job site material does.
What should be left on my property overnight during a watch? As little as possible, and nothing loose. Ladders should be down and flat, staging struck, hoses coiled, pails lidded and moved indoors or into a locked trailer, and masking either taped tight or removed entirely. Loose sheet goods and trim stock should be weighted or taken away. Flapping plastic is the worst thing to leave behind.
Is it a bad idea to book an exterior job for December in Lexington? December here averages a 45.9 degree high over a 29.6 degree low with 4.20 inches of precipitation, so workable days exist but they are unpredictable and they come with severe weather potential. Ask any contractor what their stop-work rules and minimum application conditions are before booking a winter slot, and expect the schedule to move.
Ask how a crew handles weather before you ask what it costs
The homeowner in Andover got her house finished on a normal schedule, because the afternoon that could have gone badly was handled in forty minutes and nothing was left flapping on the wall overnight.
That is the thing worth asking about when you are comparing contractors for a job in the four to five figure range. Not the lowest number. The shutdown rules, the restart standard, and whether anybody will call you.
We will come out, walk every elevation, and give you a written estimate along with a straight answer about scheduling, weather and what happens if a day gets lost. Free on site inspection, no obligation.
