.SHORT TERM... (Today through Friday night) Issued at 330am CST Wednesday Feb 19 2025

Wednesday morning surface analysis shows low pressure off the TX/LA coastline, with a cold front draped across Acadiana towards Corpus Christi. Isolated convection is ongoing along and east of this front, generally from I-49 eastward. This lingering activity will continue to taper off through the next few hours prior to sunrise as the cold front makes its way east/southeast and exits the forecast area. In its wake, a significantly colder and drier airmass will filter down into the area today. Some of this colder air is already beginning to reach our northern most parishes, with temps in the mid 30s at AEX vs mid 50s at LFT.

For most of the forecast area, current temps will resemble afternoon highs today which are only forecasted to reach into the lower 40s inland to lower 50s at the coast, and even this might be slightly on the warm side. In addition to strong cold air advection, gusty north winds and mostly cloudy skies are expected throughout today, yielding apparent, or "feels like", temps in the 30s areawide throughout today. This evening into tonight, significantly drier air begins to arrive, with PWATs (Precipitable Waters) falling below the 10th percentile a dewpoints plummeting into the teens and twenties. This will allow cloud cover to largely clear out overnight, resulting in overnight lows in the 20s and apparent temps bottoming out anywhere from 8 to 20 degrees near sunrise. Therefore, a Cold Weather Advisory has been issued for the the entire forecast area tonight through tomorrow morning due to the expected dangerously cold temps and wind chill values.

Significant cold air advection continues through the remainder of the short term period as a strong 1044MB surface high takes hold of the center of the country. Daytime highs "warm" into the upper 30s to mid 40s tomorrow and into the mid to upper 40s on Friday. Overnight, lows again fall into the 20s areawide tomorrow night, with another Cold Weather Advisory likely being required in a later forecast package. Friday evening into Friday night, moisture begins to increase slightly from the Gulf in response to a surface trough off the lower TX coast, with cloud cover building back in around sunset. As a result, overnight lows will only fall into the low 30s to near 40, with only the very northern most parts of the CWA (County Warning Area) expected to reach freezing.

Long Term
(Saturday through Wednesday) Issued at 330am CST Wednesday Feb 19 2025

Moving into the weekend, aforementioned surface trough continues to meander off the TX coast on Saturday keeping a mainly overcast cloud deck in place overhead. Some scattered shower activity associated with this trough may begin to work its way across the forecast area Saturday afternoon, with better rain chances expected to arrive Sat night. Otherwise, Saturday looks sort of gloomy and cool with highs topping out in the low to mid 50s. Rain chances then taper off through Sunday morning as the trough slides eastward and weakens. Cloud cover will gradually clear out through the later half of the day, yielding afternoon highs in the upper 50s to low 60s.

Weak surface high pressure will meander around the northern Gulf Coast through the remainder of the long term period allowing surface winds to eventually become SWrly overhead by late Mon. This will prompt a steady increase in moisture and in turn a quick warming trend through the first half of the work week. Daytime highs rebound into the mid to upper 70s Tues and Wed, while overnight lows fall into the low to mid 50s.

Marine
Issued at 330am CST Wednesday Feb 19 2025

Today, a tightening pressure gradient overhead will yield gusty winds and hazardous seas over the lakes/bays and coastal waters, with a Gale Warning in effect for all Gulf zones through 3PM. Thereafter, the western-most zones will transition to a SCA (Small Craft Advisory) with the Gale Warning continuing elsewhere through 6PM. From 6PM tonight through noon Thursday all zones (lakes/bays included) will be under a Small Craft Advisory as gusty winds and rough seas continue. Conditions begin to slightly improve tomorrow afternoon into Friday but don't significantly improve until Friday PM. Therefore, further headlines will likely be needed through the end of the work week.
