12/13 – Brantly’s “Showers Tonight, Drier and Cooler Tomorrow” Sunday Night Forecast
Cooler and drier conditions are expected for both Monday and Tuesday as high pressure dominates the region. As the next system drops southeast across the Rockies and into the Plains Tuesday, conditions will begin to moderate with highs expected to increase from mainly the lower to mid 50s on Monday to upper 50s and mid 60s. This system will continue to work east towards the Mississippi Valley region Tuesday night with a weak low pressure system developing and moving through the Lower Mississippi Valley. Moisture will increase ahead of this system and another cold front will likely produce scattered showers across the region once again. Right now, it’s looking like this next system will just be light to moderate shower activity and we are not anticipating much in the way of thunder.
Rain will quickly come to an end Wednesday morning as the disturbance moves east. We will cool off a little but the main surge of cooler air will lag behind and likely not move in until Wednesday night as another shot of cold air slides down the back side of the front over the eastern United State. This will be a dry disturbance moving through Thursday, but it should make things cool again during the daytime Thursday and cold heading in Thursday night. Thursday night looks to be one of the coldest nights of the coming week.
Friday and into the weekend temperatures will quickly moderate as southwest flow sets back up and high pressure pushes east. Moderation will be slow as we will have quite a bit of moistening up to do but once it starts Friday it may have 24 to 36 hours to do so before the system gets into the area.
