2/28 – Brittany’s “Final Day of February” Tuesday Evening Forecast
The old frontal boundary from the prior system that mostly bypassed our area currently resides across portions of MS and LA this afternoon. On the backside not much of a cool down, but there is a fairly tight moisture gradient from dew points in the upper 40s in a few spots in interior south MS to the lower 70s across far southeastern Louisiana. Winds have also slightly overachieved today with some efficient mixing. This will be fairly brief as the southerly return flow develops overnight. This will quickly allow more moisture rich air to move into the region. As this takes place, low stratus is looking to be a safe bet overnight. The stratus in some instances could build down to ground level creating some foggy morning commutes on Wednesday. The stratus should begin to mix out shortly after sunrise. The only other entity to pay respect to would be the continuation of well above average temperatures in response to the continued higher than normal heights/thicknesses as well as a favorable low level return flow.
