KEY MESSAGES

Updated at 1214 PM CDT Tue Jun 2 2026

- One last decent day of rain across the area for the rest of the work week, rain is still expected along the coast Wednesday. Temperatures will be far more seasonable Wednesday through Friday.

- Behind the front winds will pick up especially east of the MS delta and Small Craft Advisories are in effect Wednesday and through Thursday.

- Strong easterly winds and spring tides are expected to lead to minor coastal flooding for portions of coastal MS and east facing shores of SELA east of the MS River. A Coastal Flood Advisory is in effect for Wednesday and Thursday.

SHORT TERM

(Now through Friday night) Issued at 1214 PM CDT Tue Jun 2 2026

High pressure is expected to build over the area tomorrow and Friday, which will help to keep rain chances a little lower especially for areas north of I-10/12. Rain chances will still be fairly high (40-60%) for the next couple of days, especially during the daytime and early evening hours. These scattered to numerous showers will generally remain confined to the coastal areas and marine waters (south of I-12). Some localized flash flooding could be possible with these storms as well as lightning. Severe weather is not expected.

Another hazard to keep in mind will be the risk for coastal flooding. 1-2 feet of inundation will be expected for the open MS and LA coastlines. Persistent easterly winds combined with higher than normal tides cycles (Spring tide) will help to create coastal flooding issues for the LA/MS coastal areas. 1-2 feet of inundation is possible overnight tonight through at least Friday. The highest tides will be Thursday, generally. A Coastal Flood Advisory is in effect for the LA open coast and the MS coastline. MSW

LONG TERM

(Saturday through Monday night) Issued at 1214 PM CDT Tue Jun 2 2026

A return to a summertime pattern for the weekend and early next week. With the high weakening over the area, it will be quite humid as moisture returns. PWs will be quite high over the weekend with some forecast models showing PWs well above the 90th percentile for SPC sounding climatology. This will enhance rainfall chances for the weekend and early next week, especially during the daytime and early evening hours. Localized flash flooding will be the main concern with these scattered to numerous storms, especially for urban areas. Given the model trends, severe weather is not expected. Lightning and gusty winds (30-50mph) will be possible inside stronger storms in the afternoons. High temperatures will be near normal thanks to the rainfall with highs in the mid to upper 80s for the weekend and early next week. MSW

AVIATION

(18Z TAFS) Issued at 1214 PM CDT Tue Jun 2 2026

VFR conditions prevail at all area airports. Isolated afternoon and early evening showers and storms could temporarily drop conditions at airports to MVFR, so TEMPO groups are in effect to reflect this forecast. Wind shifts greater than 30 degrees will be expected throughout the forecast period. MSW

MARINE

Issued at 1214 PM CDT Tue Jun 2 2026

A backdoor cold front will drift across the coastal waters tonight and early Wednesday. After it moves through winds will shift to easterly and will increase in speed, especially the waters east of the MS Delta where solid SCY conditions are expected Wednesday. The front will stall and washout by Thursday and as high pressure builds over the southern Appalachians the pressure gradient will increase leading to moderate onshore flow returning. Small Craft Advisory in effect for Wednesday and may be needed toward the weekend.
