Cloudy, Breezy, & Cold Friday – Next Chance Of Snow Monday

Weather

Rain & snow taper off, minor accumulations may lead to a few slick spots early Friday

Snow tapers off to flurries/showers through early Friday morning.

From the Lincoln – Moore – Franklin (TN) advisory via NWS Huntsville:

* IMPACTS...PLAN ON SLIPPERY ROAD CONDITIONS WITH SLUSH-COVERED
  ROADWAYS POSSIBLE. THE HAZARDOUS ROAD CONDITIONS MAY IMPACT THE
  FRIDAY MORNING COMMUTE.

* ADDITIONAL DETAILS...EMERGENCY MANAGEMENT OFFICIALS REPORTED
  PORTIONS OF HIGHWAY 231 AND ROUTE 129 HAD MULTIPLE SLICK SPOTS
  AND SEVERAL CAR WRECKS. SNOW MIXED WITH SLEET AND RAIN WILL
  CONTINUE THROUGH THE EVENING AND END IN THE EARLY MORNING HOURS.
  HOWEVER, SUB-FREEZING TEMPERATURES WILL ALSO ALLOW THIS TO
  FREEZE AND BECOME PATCHY BLACK ICE, AND MOTORISTS SHOULD 
  EXERCISE EXTREME CAUTION AND LIMIT TRAVEL TO ONLY WHEN 
  ABSOLUTELY NECESSARY.

For everyone NOT experiencing the slush, it’s just wet and cold early in the morning. Temperatures hover in the mid-30s overnight. That means mostly wet roads if there’s any moisture left at all: no real threat of icy roads in Huntsville except in the higher elevations on Monte Sano, Huntsville and Green Mountains.

Friday just looks cold.

Expect highs in the 30s/lower 40s with a wind chill staying between 25ºF and 35ºF all day long thanks to a cutting north wind up to 20 miles per hour.

It also takes more than 30s at the ground to make it snow!

It involves the temperature profile through a large depth of the atmosphere, but it’s especially critical that the lowest 2,000-3,000′ above the ground be at or below 32°F.Today’s profile is a a good freezer on top of a fridge that isn’t running very well and needs a visit from the Maytag man.

Temperature changes in the lowest 10,000′ of the atmosphere can make a big difference in precipitation type! The Thursday/Friday profile is most similar to the first one: mostly rain and just barely too warm for a big snow!

In other words, the top is good to go for snow; the bottom? It’s iffy at best and warm enough to spoil the food at the worst. That’s why the higher elevations have a better shot at this than the Huntsville-Decatur-Athens-Shoals areas.

I’m not going to guarantee you have zero snow, but I don’t think you need to make snow day preps for Friday morning in those areas.

Monday offers a little better chance, but even then: same problem. If we can get that fridge cold enough, we’ll get a good one. Otherwise, expect a foul odor of spoiled snow hopes again next week.
