SHREVEPORT, La. (KTAL/KMSS) – The weekend started with sunshine, a southerly breeze and very warm and humid conditions. Heat and moisture are moving in ahead of a cold front that will move into ArkLaTex early Sunday morning. The lowest temperatures since March will be felt during the next week.
Storms intensify Sunday evening: There is a chance for a few storms to develop between 5pm and midnight across northern ArkLaTex. Any storms that may develop in the late afternoon or evening will catch warm air and become capable of damaging wind gusts or large hail.
The Storm Prediction Center has severe weather forecasts for the northern ArkLaTex until sunrise Sunday. As temperatures cool after sunset into the 60s overnight, storms will become less likely to become severe, but an isolated severe storm capable of the above hazards could develop overnight.
Continued scattered showers on Sunday: Thunderstorms will gradually lose strength during the night, and a cold front will act as a plow that will push the rest of the rain south into the rest of our counties and parishes during Sunday.
What once looked like a promising day of needed precipitation now looks less likely. The morning precipitation could disappear completely during the late afternoon, leaving us mostly cloudy. If we are able to warm up enough on Sunday, we could see some rearrangements during the afternoon and evening.
Temperatures will be cooler, into the 70s and 80s, and no severe weather is expected.
The heaviest rain over the next 24 hours will be north of I-30, where forecast models think we could see half an inch to 1 inch of rain. Accumulations in the rest of ArkLaTex will be sparse, averaging a tenth to a quarter of an inch. Some areas may even miss the rain on Sunday.
Colder weather takes over Monday: As skies gradually clear late Sunday into early Monday, cold air will pour south into the region. Monday’s high will be in the upper 60s with a low in the 70s.
The coldest air will be felt Tuesday through Thursday morning. Midweek highs under sunny skies will be in the low to mid 60s on Tuesday and Wednesday. In fact, overnight lows will be in the 30s in some areas Tuesday night and Wednesday night. If we do see a freeze, it will be in northern ArkLaTex Tuesday night into Wednesday morning. Make plans to cover sensitive plants and vegetation in southeast Oklahoma and southwest Arkansas.
Dry weather is expected for most of next week with a warming trend to highs in the 70s on Thursday and low 80s on Friday and Saturday.
