Lead Forecaster Daniel Crawley
Good Monday afternoon to everyone. Sunshine has returned to the region after a long stretch of cloudy, wet and chilly days. The sun will appear again on Tuesday but changes will quickly occur for the midweek timeframe.
A large storm system back over the Western US will cross the Rockies and emerge out over the Plains by Wednesday. This will scoop up a lot of gulf moisture and bring it back into the Southeast US.
Looking at the moisture loop below, clouds will increase late Tuesday night and precipitation returns to the region by Wednesday afternoon . A wave of surface low pressure will also form across Georgia slowing down the process of clearing things out. Rain will peak in intensity on Wednesday night through the morning hours of Thursday.
Precipitation amounts look to be in the 1-3 inch rain for the Western Carolinas through Thursday evening. That kind of rainfall could produce some isolated flooding or poor drainage areas.
With cold, dry air in place as the moisture overruns…we are talking about cold wedge type setup during the event. (40’s)
