9/18 – Brittany’s “Cool” Sunday Evening Forecast

Tomorrow will likely be drier. The ridge will continue to build over both the southern Plains and Lower MS Valley likely stretching east across most of the southeastern CONUS. The ridging aloft will help suppress the deeper moisture south with PWs dropping to below 1.3″. The slightly increasing suppression and especially the lower moisture content will pretty much shut off the rain potential for Monday. LL temps will also start to slowly climb and this will translate to warmer afternoon highs with most of the area in the lower 90s by Monday.

Heading into the extended portion of the forecast the main focus will be on the heat and possibly record breaking in a few locations Wed-Fri. Medium range models appear to be in fairly good agreement now heading into the back end of the next work week. Medium range ensembles are also in decent agreement. With that confidence is high in a warm and mostly dry forecast. Only thing to really discuss for much of the extended will be the outright domination by the ridge. It will shift some from east to west and back to the east but it will dominate the region the entire time. This will keep moisture from returning and will also lead to temps slowly climbing through the week.
