Radar depicting patchy light rain/sprinkles across the forecast area. Rains associated with an opening mid/upper level low advancing east off the Texas coast and accompanied with an inverted surface trough. Feature/s will continue and eastward advance through the remainder of the afternoon and evening with any lingering rains coming to an end.

A shortwave trough separate from the aforementioned southern feature will dig southeast across the plains and through the low and middle Mississippi valleys this evening bringing a reinforcing shot of cold air to the region. This will by followed by a dry northerly flow through the column resulting in clearing skies between the exiting trough and modest ridge following through the plains. PWAT (Precipitable Water) is expected to plummet to 0.25 inches or less for Friday and Saturday with strong subsidence in place, before starting to edge upward Sunday.

Temperatures well below the norm are expected to remain in place for Friday and the weekend. Clear and cold nigheights ahead, while reasonably mild days will emerge under sunny skies while winds remain light. Next trough advances across the area late Sunday, but moisture return looks increasingly limited per latest models. Have thus removed any rain chance during this time-frame. Temperatures will be trending upward going into the new workweek and more toward the climatological norms with the dry weather pattern continuing.
