12/7 – Brittany’s “Spring-Like Pattern” Wednesday Evening Forecast
Fog that is the main forecast problem, besides the heat over the area. This abnormal warmth will continue to with highs expected again in the 80s tomorrow and possibly even Friday. Maybe we will see an improvement as clouds and even rain chances begin to increase this weekend.
No change in the pattern tonight through Friday night. Ridge will continue to dominate and the BL will remain rather moist. With less cloud cover already compared to last night, no dry air, and light winds the conditions are prime for another dense fog night due to radiational cooling. Temperatures will likely fall quickly initially but then fog will probably develop quickly this evening and then expand across the region. Dense fog advisory has already been issued.
Saturday we may finally see a slightly better chance of rain as the ridge will being to become suppressed due to a strong s/w moving through the central and northern Plains. This will try to push a cold front into the Lower MS Valley but at the least it should allow heights to lower a tad and may even see a subtle wave move across the region allowing for a slightly better chance of convection developing. This should increase the cloud cover and that may help keep highs down a degree or two.
Extended portion of the forecast is going to see things wake up with multiple rounds of showers and some embedded thunderstorms and then all signs are pointing towards a rather potent system mid week.
