Synopsis - Elevated southeasterly flow is expected to prevail into the weekend amid a tightened pressure gradient between surface high pressure to the east and a series of low pressure systems developing across the plains. Rain chances should remain low although an isolated light shower or two cannot be ruled out.

New UPDATE

UPDATE
Issued at 1018 PM CDT Tue May 21 2024

A quiet but warm and humid evening underway, with low clouds continuing to stream inland from the Gulf while cirrus slides east aloft. Inherited forecast is in good shape, although some minor adjustments were made to hourly Td and Wind grids to align with obs and expected short term trends. The only change worthy of an update to the text products was to insert Exercise Caution headlines for the coastal waters zones west of Intracoastal City as obs sites near the coast have indicated elevated winds from 15 to 20 KT this evening and this should persist through the night.

SHORT TERM
(Tonight through Thursday night)
Issued at 200 PM CDT Tue May 21 2024

Very little to no change in the day to day forecast and overall weather pattern for the period. The surface high pressure will remain off to the east of us with a disturbance moving into the Central Plains. As a result of that, we will have elevated to gusty southerly flow bringing in an abundance of moisture. Aloft there is a stubborn high pressure centered over Mexico, with ridging extending into the Gulf Coast States. This should keep us "dry" in terms of rain however it will be hot and humid.

MaxTs will range from the upper 80s to mid 90s with MinTs in the 70s. Dewpoints will be in the 70s as well yielding heat indices in the 94-102 range. Tis the season. Stay cool.

LONG TERM
(Friday through next Monday)
Issued at 200 PM CDT Tue May 21 2024

A repetitive early summer pattern will persist throughout much of the long term period, with little day to day chances anticipated.
Aloft, a strong mid to upper level ridge will remain anchored from north/central Mexico across the Gulf of Mexico throughout the forecast period. This will result in a persistent warm and dry pattern, with highs expected to warm into the lower to mid-90s each afternoon through the beginning of next week. In addition, southerly flow at the surface will keep an continuous fetch of Gulf moisture across the region, allowing dewpoints to remain in the low to mid- 70s. This will in turn, hinder overnight lows from fall beyond the low to mid-70s each night.

Around the end of the forecast period models continue to want to swing a cold front through the region, although there remains a decent bit of uncertainty. Regardless, if this were to occur cooler temps are unlikely however, a reduction in dewpoints looks possible which would at least bring down heat indices and overnight lows for a brief period. This front may also be accompanied by a small chance showers early Tuesday, which looks to be our next best chance of precip for the foreseeable future.

AVIATION
(00Z TAFS)
Issued at 641 PM CDT Tue May 21 2024

MVFR to VFR conditions will persist through the evening hours.
Eastern sites, ARA, LFT continue to see mostly clear conditions through late evening before cloud cover builds from the west lowering and bordering MVFR thresholds. Western sites BPT and LCH will see these BKN decks under 3kft throughout the early morning hours keeping conditions primarily MVFR. Eastern and inland locations have more favorable chance at seeing periods of ground layer BR after 11z, therefore minimal reduction of visibility expected. Upper level cirrus decks above 10kft will continue through morning and afternoon while low level clouds become scattered under 5kft during the mid afternoon.

MARINE
Issued at 200 PM CDT Tue May 21 2024

Southeast flow is expected to prevail through the period. Winds and seas are forecast to increase today due to the pressure gradient increasing between surface high pressure to the east and low pressure across the Plains.
