An upper trough over the Plains barrels into the eastern states through Wednesday, with an associated surface low meanwhile bringing a strong cold front through the forecast area late tonight into Wednesday morning along with a line of precipitation. Instability continues to remain limited with the frontal passage and am anticipating the convection to remain mostly as showers. Have gone with likely/categorical probability of precipitation shifting across the area with the frontal passage, with dry conditions developing Wednesday as the front exits to the east. Dry conditions continue over the area through Saturday as the eastern states upper trough moves well off to the north and another upper trough develops over the central states. This next system is anticipated to evolve into an upper low Sunday into Sunday night somewhere over the north central Gulf or central Gulf, and depending on how this plays out and where the associated surface low forms could determine if our area ends up with isolated showers on Sunday or much more coverage. Have for now continued with slight chance probability of precipitation for Sunday and will continue to evaluate. Dry conditions are anticipated to follow for Monday and Tuesday.

Lows Wednesday night range from the mid to upper 40s inland to the lower 50s near the coast, then the coldest air yet of the season follows for Thursday night when lows range from the upper 30s inland to near 50 at the immediate coast. Lows Friday night will be just a tad warmer, then lows gradually moderate through Monday night to range from the mid/upper 40s well inland to the mid 50s at the coast. Highs on Wednesday range from the lower 60s well inland to the lower 70s at the immediate coast. Highs on Thursday range from the lower 60s well inland to the mid 60s near the coast then moderate to the lower to mid 70s by Tuesday. A High Risk of rip currents is in effect for Wednesday and Wednesday night, then a moderate risk is in effect for Thursday. A low risk of rip currents follows for Thursday night through Sunday night. /29
