Near Term
(Now through Thursday) Issued at 416pm CDT Wednesday May 29 2024

A broad upper trough remains over the eastern CONUS, with an amplified ridge over the Plains and another trough over the Pacific NW. This will maintain a nearly zonal or slight west-northwest flow aloft over our area. At the surface, a weak boundary has moved offshore and is over the Gulf of Mexico to our south. This boundary will remain nearly stationary and gradually become more diffuse through Thursday. Surface high pressure centered over the Great Lakes region will continue to ridge south to the Gulf coast, with a weak reinforcing frontal boundary dropping south to the coast by late Thursday. This boundary, and a series of occasional shortwaves moving around the base of the upper trough could provide the focus for some isolated convection across our area, especially interior counties, just as occurred today. Today's isolated convection has primarily been diurnally driven so any lingering storms this evening will quickly diminish after sunset. Same for Thursday, with any isolated convection that may form during the day again quickly diminishing after sunset Thursday evening. Low temperatures tonight should range from the mid to upper 60s across interior counties and in the low to mid 70s closer to and along the coast. The heat continues on Thursday with near normal to slightly above normal temperatures expected, as highs will range from the lower 80s up along the Highway 84 corridor (which will be behind reinforcing front), to the upper 80s and lower 90s southward down to near the I- 10 corridor. A little cooler again down along the beaches (mid to upper 90s), where moderation from the onshore flow will be most effective. DS/12

Long Term
(Friday through Wednesday) Issued at 416pm CDT Wednesday May 29 2024

Ridging aloft moves overhead Friday as a trough remains draped down the East Coast. A surface high settles into the Great Lakes region late in the work week and surface winds gradually take on more of a southerly component. Isolated showers and storms are possible Friday afternoon into the early evening hours as moisture slowly begins to rebound and a subtle shortwave nudges toward the area. As we roll into the weekend, the trough aloft digs into the western Atlantic as the ridge slides east of the area. Several rounds of weak shortwaves cruise through the generally zonal flow left in the wake of the ridge this weekend (lingering into Monday). The surface high builds into the East Coast on Saturday and builds over the western Atlantic as we head into Sunday. Increasing onshore flow in the lower levels will usher more moisture into the area, allowing dewpoints to surge into the 70s each day. Coverage of showers and storms is expected to be higher each afternoon over the weekend and potentially on Monday given daytime heating, weak forcing from the shortwaves cruising overhead, and a weak surface boundary wobbling around near the coast. The highest coverage on both Saturday and Sunday will be across southeast Mississippi as the surface boundary likely pushes inland in that region, providing a focus for storms in the afternoon. The exact timing of the showers and storms still remains a bit uncertain given that it hinges on the placement and timing of the subtle shortwaves moving into the region. We remain in somewhat of an active pattern through the middle of next week with isolated showers and storms possible each afternoon.

Beach Note: Rip current risk remains LOW Thursday through Friday night with a bump to MODERATE on Saturday and Sunday. RCMOS probabilities indicate the risk will likely remain MODERATE through at least Tuesday of next week. 07/mb

Issued at 416pm CDT Wednesday May 29 2024

A light diurnal wind flow, offshore at night and onshore during the afternoon, will continue into Thursday morning, but flow become more predominately east to southeasterly Friday through Sunday and then more southerly by early next week. Expect a return chance for showers and thunderstorms to the marine area by the weekend. No significant hazards to small craft are expected through the weekend. DS/12
