Watch for patchy ice early Friday morning!
Clearing and colder tonight!
Clouds, rain and snow move out Thursday evening leaving us breezy and downright cold tonight! Temperatures plunge into the lower and middle 20s by daybreak Friday. That cold air chills roads quickly, and any of those usual trouble spots (Chapman Mountain, I-565, etc.) could have some patchy ice for the drive into work and school on Friday.
The Wind Chill will be rough, too! Expect a ‘feels like’ temperature in the 10s early Friday, but the breeze will settle down some throughout the day. A sunny sky and a lighter north breeze allow at least a little warm-up: highs in the lower and middle 40s Friday afternoon.
Some school systems are delaying!
Weekend weather update
Expect a hard freeze Saturday morning! We’ll drop below freezing around 9 PM Friday and stay there until around 9 AM Saturday. At least we’ll warm up a little in the afternoon! Expect highs in the 50s with a light variable wind that gradually becomes a little stronger from the southwest later in the day.
Clouds thicken late Saturday night into Sunday, but we’re still expecting MOSTLY dry weather for Sunday. Temperatures jump from the mid-30s to the lower and middle 50s Sunday afternoon. A few brief, light showers may develop in the afternoon and evening, but the next round of widespread, significant rain looks to be in here on Monday.
Rain then more cold
A disturbance embedded in the jet stream over the Pacific now moves across the southwestern United States toward Alabama and Tennessee by Sunday night and Monday. Ahead of it, warmer air moves north bringing temperatures up a little: close to 60ºF by Monday afternoon.
There’s also a good chance of a soaking rain: again. Expect around 0.5″ to 1.0″ of rainfall between Sunday night and Monday. Behind the system, a strong cold front blasts through on Tuesday dropping temperatures sharply for the rest of the week!
Rumors of more snow?
As of Thursday, it’s been 1,821 days since Huntsville International Airport recorded at least an inch of snow for the winter season. The historic average is around 2″ to 2.5″ per year; lately, snow has been hard to come by!
The light snow that fell on Thursday didn’t add up to much in town, but it did snow enough to measure in a few areas of northwestern Alabama and Tennessee.
Will there be at least one more chance of some snow? Focus on next Wednesday: cold air blowing in and just enough moisture to squeeze out some snowflakes. Yes, it could technically snow again, but it does not look like it will be very significant even if it does come.
The cold air will be significant, though! Temperatures plunge to the 20s for lows and 40s for highs again through the end of next week.
