Good evening Tennessee Valley and a very Happy Friday! A few scattered showers this morning, but mostly we were plagued with a low cloud deck this afternoon that prevented temperatures from warming up. Actually temperatures dropped through the course of the day with the high of 48 at HSV occurring at 1:25 this morning. As the large trough and associated area of low pressure continue to push north through Saturday some light morning clouds will give way to ample sunshine through Saturday afternoon. This will make for seasonable highs in the lower 50s across the Tennessee Valley.
Not bad, but it wont last as a small trough looks to push through to our north and bring the opportunity for a few scattered showers Saturday night and through the day Sunday. It wont be a complete washout and most of us look to dry out after the lunch hour, but you may have to contend with a few showers especially for morning services.
This wont last long either and zonal flow should take hold behind that making for sunny skies on Christmas Eve and mostly sunny skies on Christmas Day. On the note of Christmas Day it looks to be warm with a forecast high of 56 degrees. The EURO was trying to bring in the chance of a passing shower, but at this time I’m going to go ahead and leave many of us dry and mostly sunny.
Wednesday 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. 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.
