10/9 – Brittany’s “Dry & Chilly” Sunday Night Forecast

Dry high pressure will continue to control the area`s weather through the short term. Expect cool nights and warm afternoons with near to slightly below normal overnight temperatures and slightly above normal afternoon temperatures with only a few passing high clouds.

As upper level trough shifts east and weak ridge builds in its wake, temperatures will begin to moderate the first couple days of this upcoming week. Will likely start to see dewpoints creeping back up late in the day on Tuesday as surface high shifts east and onshore flow regime begins to develop. Its that moisture return that will be the start of the first appreciable chance of rain in about a month. Medium range models are showing an amplifying trough moving west to east across the country Wednesday in Thursday. Showers and some thunderstorms will begin to develop across the region as moisture increases throughout the column (some of that is partially remnant moisture from Julia that makes it into the western Gulf). Instability will be on the increase as well but based on current model soundings, this will likely just support thunderstorms. The base of the trough looks to be way too far north to bring shear up enough to support anything remotely severe. Nevertheless, the local area finally has a real decent shot to get some much needed rainfall.
