Sunday Evening Forecast Discussion – 8:35 p.m.

 

It was another beautiful fall day across Central Alabama with sunny skies and nice temperatures. Water vapor imagery indicates an upper level low to the east just off the South Carolina and Georgia coast with a weak ridge building in across the Tennessee and lower Mississippi River valleys.

Tonight, temperatures are not expected to drop as low as the past few nights. Models are showing that easterly flow will advect in low level moisture overnight. Additionally, winds may remain up just a bit to prevent temperatures from dropping as low as they have been the past few nights. However, overnight lows are still expected to be in the upper 30s to low 40s.

Into the work week, upper level flow will remain rather zonal on Monday. Clouds will overspread much of the forecast area as easterly winds continue to push low level moisture to the west. On Tuesday, a trough will move across the forecast area. Models are drier today than they were yesterday with precipitable water values of only 0.75 inches. Additionally, model soundings indicate the moisture will be rather shallow. A few sprinkles or light showers could be possible on Tuesday but there is not enough confidence for any mention in the forecast.

For the middle part of the week, the trough deepens off the east coast as the ridge amplifies over our area. Therefore, expect mostly sunny skies and temperatures near normal in the Wednesday-Friday timeframe. Thanksgiving morning will be the chilliest portion of this timeframe. Thanksgiving morning low temperatures will be in the upper 30s and low 40s with surface high pressure centered over the area.

Models are in fairly good agreement as a trough to the north moves a front through the area on Saturday. Models indicate that this front will be dry with a cooler air moving in behind the front for next weekend.
