Good evening Tennessee Valley and a very Happy Monday! A perfect Christmas Eve with sunny skies and temperatures sitting hardly below average with HSV coming in at 51 degrees. Party cloudy through the overnight, but clouds will be on the increase as we head into Christmas Day. Given the addition of a few clouds lows tonight should stay in the lower 30s.
Christmas day looks to be mostly dry with only remote chances for a couple scattered showers especially across NW Alabama. This thanks to a very gradual increase in SW flow through Christmas Day that will also cause an increase in cloud cover as the day goes on. Temperature wise we’ll be just at or just above average with highs right around 52 or 53 degrees.
Partly Cloudy for Wednesday, but we should remain mostly dry with the best chance of showers coming in the evening as the approaching trough responsible for the ridging pattern and increase in SW flow draws closer. The increase in SW flow will make for a nice warming trend with Wednesday looking to finish right at 59 or even degrees.
Wednesday night and beyond looks to bring another soaking. A developing trough will bring cause for ridging to develop east of the Mississippi River which will greatly increase our southerly flow into the Tennessee Valley. This developing trough looks to have an associated closed low that will travel north through the day Thursday and Friday along the aforementioned ridge . The good news here is that we will remain on the warm side of the low. The bad news is that Thursday looks to be incredibly wet with PWATS already higher than 1 inch.
With the continuation of southerly flow through the weekend and the presence of a couple different fronts, we’ll hold onto rain chances through the weekend and early next week. By NYE I noticed another developing trough to the west that could once again bring a fair amount of rain into next week, but there was a fair amount of disagreement among the models.
