3/11 – Rob’s “Continue Warm/Humid” Afternoon Forecast
High pressure off the eastern seaboard will keep southerly winds over the area into the weekend. Higher moisture values will also become evident as the chance for patchy fog will increase tonight into Friday morning. Not expecting widespread or dense at the moment since a few variables are out of tolerance for development, that is unless the area can decouple and keep clouds out of the picture.
Upper level high-pressure will continue to dominate the northern central Gulf through Sunday bringing well above normal temperatures to the area. Meanwhile surface high pressure will slide east of the area through the latter half of the weekend. A very deep low pressure system bringing a major winter storm over the Rockies will pull eastward into the western Plain states by Sunday evening. This will bring an associated cold front into east Texas and western LA by Sunday night with showers and isolated thunderstorms returning late Sunday and into Monday. Low pressure system will move into the middle Mississippi Valley bringing a cold front into region by Sunday night. This will bring a chance of showers and thunderstorms into the forecast area Sunday night and Monday. Due to the track potentially being well to our north…any significant shower and thunderstorm activity could be limited.
The front is expected to stall over the northern Gulf Monday with showers lingering as the frontal boundary washes out on Tuesday. Another disturbance will kick through the southern and central Plains by midweek bringing a chance of showers and thunderstorms on Wednesday.
