.SHORT TERM... (Tonight through Wednesday night) Issued at 321pm CST Monday Nov 28 2022

Southerly winds have developed as high pressure slides off to the east. As the next frontal system begins taking shape over the Plains states, gradient flow will increase. A Gulf airmass will be carried northward on southerly flow, pushing dewpoints back into the upper 60s by tomorrow morning. Patchy area fog may result within the warm sector, particularly along the coastline where slightly cool near-shore waters could saturate surface layers.

Tomorrow morning, the next frontal system will start its march across the central US. As jet maxes aloft become coupled, elevated flow will mix down towards the surface, spreading a broad area of increasing speed and directional shear across east TX/AR/LA/MA. At the same time, the warm front slowly lifting through LA will be driven further north ahead of the approaching system. Diurnal heating within the warm sector and shear interactions could generate an area of showers and thunderstorms across central Louisiana by mid- day. Forecast CAPE of 1500 to 2500 J/kg and surface to 3km SRH 300 m2/s2+ do point to an environment which could support organized supercells during the early afternoon hours across central and southwest Louisiana. Strongest storms could carry large hail, strong to damaging wind gusts and some tornadoes, thus all interests should remain weather-aware throughout the day and especially into overnight hours.

The front is set to cross the area during the evening hours tomorrow, continuing the severe threat well after the sun has set. Shear values decrease during this period as flow becomes more veered, which may transition the threat to more of a wind risk. However, all hazards may still be supported through the overnight hours. Heavy rain may also be possible at times, particularly with stronger storms.

Storm chances come to a close by Wednesday morning as cold air pushes down into the region. High pressure will swiftly build in behind the front, leading to clear skies and cooler weather to end the shortterm period.


Long Term
(Thursday through next Monday) Issued at 321pm CST Monday Nov 28 2022

Thursday will be rather chilly as the cold surface high ridge keeps temperatures starting off in the 30s only warming up to the upper 50s to near 60. As the upper level pattern becomes more zonal and the surface high slides east, temperatures will be about 10 degrees warmer for Friday with southeasterly winds returning.

Saturday through Monday will see a mid to upper level zonal pattern to our north, with a ridge over the Gulf of Mexico northward across SE TX/S LA. This will bring even warmer temperatures with lows in the lower to mid 60s, and highs in the mid to upper 70s, which is about 10-12 degrees above normal. No significant frontal systems or lift to generate significant rainfall. Blended guidance going about 20-25% for Saturday with isolated-scattered showers, with much less chances for Sunday and Monday.

Issued at 321pm CST Monday Nov 28 2022

Onshore winds will increase tonight bringing warm and moist air over relatively cooler near shore waters with patchy fog to result. Elevated onshore flow will occur during Tuesday into Tuesday night ahead of a cold front. Showers and thunderstorms will develop ahead of this system. The cold front will move through by early Wednesday morning with strong offshore developing in its wake. Gusts up to gale force are possible, prompting a Gale Watch.
