SHORT TERM
(Today through Wednesday night)
Issued at 252 AM CDT Mon May 6 2024

A warm and muggy early morning ongoing across the region although, thankfully, with a clear radar for the first time in several days.
As expected, areas of fog have developed once again where winds have become light or calm and it's expansion is easily observable on night fog satellite channels. Expect fog to continue expanding through the morning, but widespread dense fog isn't anticipated. Where winds have remained generally above five knots, the mixing has kept clouds off the surface streaming around 1.5kft. Visibilities should improve no later than 14Z.

Winds will gradually increase through the day in response to a deepening surface low over the central plains that will initialize a severe weather outbreak across Oklahoma and Kansas. Forecast winds look to remain below advisory criteria, but will be in the 15-18 knot range by this afternoon gusting to 25. A moisture plume being advected into the central plains low will get some lift from a weak shortwave traversing the region this afternoon to initialize isolated to scattered convection. The highest PoPs will be across central Louisiana and interior Southeast Texas along the trajectory of the highest moisture. Activity should wane by about 22Z as the shortwave lifts off to the Northeast.

The central plains low will keep winds elevated enough tonight into Tuesday morning to prevent any significant fog formation.
Drier mid level air streaming up the Texas gulf coast Tuesday will allow for the first day in over a week that should have zero precipitation anywhere across Southeast Texas or Southwest Louisiana. The downside is that with the lack of rainfall, temperatures will climb into the mid to upper 80s Tuesday afternoon and then into the lower 90s Wednesday across central Louisiana and interior Southeast Texas. As has been advertised, this will push heat indices Wednesday afternoon close to triple digits for the first time since last fall.

LONG TERM
(Thursday through Monday)
Issued at 252 AM CDT Mon May 6 2024

Thursday will start off unseasonably warm and dry before a cold front sags south into the area. Highs will be in the upper 80s to lower 90s with dewpoints in the 70s. This will yield heat indices at and below the 100 degree mark. As the front works into the area, we will see isolated to scattered showers ramp up mainly across the northern half of the CWA

The rest of the long term will be more mild with temperatures at or below climatological normals. At the surface a weak ridge will build in over the weekend. Aloft, model guidance differs this far out. We could see isolated showers return to the forecast as early as Sunday with a disturbance moving in over the Rockies and into the Plains.

AVIATION
(06Z TAFS)
Issued at 1153 PM CDT Sun May 5 2024

VFR all sites late this evening, though some decreased VSBYS are noted on area observations along with low clouds lifting north across eastern TX. Have included a stretch of MVFR all sites, mainly VSBY driven for the Acadiana terminals and lower CIGS elsewhere. The VSBYS will improve quickly after sunrise, but the CIGS will stick around a bit longer, through most of the morning at least. Rain chances are generally low except for KAEX, where CAMs are showing some scattered afternoon convection. Generally preserved the inherited PROB group from the previous forecast.
Light winds overnight will increase from the SE and become gusty during the afternoon, settling down around sunset. MVFR CIGS progged to return MON evening.
