Freeze warning in effect through Monday morning; hard freeze expected for the Valley

The National Weather Service in Huntsville has issued a Freeze Warning  for Lauderdale, Colbert, Franklin, Lawrence, Limestone, Madison, Morgan, Cullman, and Marshall Counties. The warning lasts through 8AM Monday morning.

The warning does not extend into Southern Tennessee and Northeast Alabama because these areas have already seen widespread freezing temperatures this season. Freeze Warnings are typically only issued by the National Weather Service through the first freeze of the season. Otherwise we would have long stretches during winter with Freeze Warnings needed every night.

Huntsville International has yet to record a temperature below 33°F this season. We hit 33°F October 30th, which was the coldest morning we’ve seen so far this fall. We’ll finally get our first freeze Monday morning, and likely our first hard freeze (temperatures below 29°F) too!

This comes a little later than average, with the average first freeze occurring in Huntsville on November 2nd. It will likely be right on time for the average hard freeze though, which occurs November 12th.

Through Monday morning, expect mostly clear skies as well as light northerly winds. These conditions combine to allow cold, arctic air to pool at the ground level, which means temperatures will plummet into the mid-to-upper 20s. This is far too cold to safely leave animals outside exposed to the elements, so please bring them inside or provide a warm shelter for the overnight hours.

You will also want to protect your building’s plumbing from potentially freezing over and bursting, which is a very costly as well as damaging situation. Let kitchen and bathroom faucets drip overnight, and leave the cupboard doors open so that warm air can circulate around the pipes.

The cold air might be a little late getting to us, but it’s coming in full force now! Temperatures will try to warm into the low 60s on Tuesday before our next cold front comes through and knocks us back into the 50s for the rest of the week.

Our average high temperature this time of year hovers between 61°-64°. We’ll be near average on Tuesday, but every other day over the next 7-10 will likely come in below average. This is quite a difference from the first week of November, which came in around 7°F above average!
