The deep upper level low and trough over the eastern U.S. will lift northeast while surface high pressure across the lower Mississippi River moves east over our area by the end of the day. This pattern will allow for deep layer dry air to overspread the region today resulting in clear skies. With the surface high moving over our area, winds will be much lighter across the area on Tuesday. It will be cool today with highs remaining well below normal, generally topping out in the low to mid 50s across the entire region.
High pressure will continue to dominate the area tonight with mostly clear skies and well below normal low temperatures continuing as well. Temperatures tonight expected to be very similar to this morning’s low temperatures, so another freeze is expected over most of the area except again possibly along the barrier islands. Lows in the 25 to 30 degree range along and north of I-10, and in the lower 30s to the south of I-10, mid 30s barrier islands.
On Wednesday high pressure moves off to the east of the area with a weak return flow developing by late in the day, especially over the western half of our forecast area. This will bring gradually increasing moisture to the area, and allow for slightly modified temperatures on Wednesday. Highs will range from the mid and upper 50s over inland areas to the lower 60s closer to and along the coast. By the end of the day on Wednesday, a developing storm system over the plains states will begin to bring an increase in mid and high level clouds from the west to the area as well. At this time it appears that any precipitation associated with this developing system will remain to the west of our area through midweek.
