Today’s highs look to remain on the cool side with upper 40s/lower 50s interior to the lower half of the 50s for coastal sections. If clouds hold in longer than expected today, then a lower adjustment to highs will be possible. Under clearing skies and light winds, a good radiational cooling channel supports a cold night tonight with lows at freezing from 29 to 32 over the interior. 37 to 43 coast. Thursday, with the next cold front diving southeast over the lower Mississippi River valley, southwesterly winds out ahead during the day will give us slightly warmer high temperatures, ranging from the upper 50s to the lower 60s.
After that next front pushes through the area, a reinforcement of cold air from the northwest will result in temperatures staying slightly below average as we head into the weekend. Expect highs to be in the 50s Saturday with lows back in the 30s by Saturday night.
The next low pressure system and associated cold front will slide through the Gulf Coast region late Sunday into Sunday night. This system will maintain will lack a deep pool of available moisture to tap into. As a result, only a brief period of isolated showers is expected Sunday evening. Temperatures will remain cooler than average with highs in the 50s Sunday and lows in the 30s and lower 40s Sunday night.
