1/3 – Brittany’s “Wet” Tuesday Night Forecast

It’ll be a warm and wet night in advance of an approaching cold front that will make its way overhead by early tomorrow morning. By tomorrow afternoon, conditions will be clearing with partly cloudy skies and temperatures maxing out well above seasonal norm.

A largely zonal flow regime will be the dominant feature through the long term period. Embedded within this zonal flow regime, a weak and fast moving shortwave trough axis will slide through the Lower Mississippi Valley Sunday into Monday. This fast moving upper level feature will likely send a very a weak frontal boundary into the region, and this front will stall and dissipate over the forecast area as winds turn parallel to the frontal boundary. At this time, heavy rainfall and thunderstorm activity is not expected, but scattered showers and overcast skies are expected to linger from Sunday into Monday. Given the zonal flow pattern aloft, temperatures are expected to be near average with highs in the 60s and lows in the 40s.
