KEY MESSAGES

- A cold front and coastal low keeps a Marginal Risk of Excessive Rainfall and Severe Weather through tonight

- Strong northerly winds will create hazardous conditions over marines zones overnight prompting a Gale Warning to be effect through Wednesday afternoon

- Hazardously cold temperatures and wind chills are expected areawide both Wed and Thurs nights

SHORT TERM
(Tonight through Thursday night)
Issued at 330 PM CST Tue Feb 18 2025

A deepening coastal trough followed by large area of upper level speed convergence is resulting in showers with scattered thunder to develop over the coastal waters and lift onshore through the evening. Some showers may be efficient rain producers, particularly along the I-10 corridor where a Marginal Risk for excessive rainfall and Severe Weather is in place through the overnight hours. As the low shifts east with the frontal pattern following offshore TX/LA Coast, strong northerlies will take place resulting in hazardous marine conditions. A Gale Warning will be in place across the offshore waters beginning midnight. Inland temperatures will fall to the low 40's and potentially upper 30's across interior portions of the area before a slight moderation during the day tomorrow with skies remaining cloudy.

While stronger winds / gusts will begin to ease tomorrow afternoon, temperatures will plummet through the evening hours. A fairly decent pressure gradient initiated by the CAA behind the front will keep winds enhanced through the overnight hours into Thursday morning. Skies will also clear. A combination of elevated northerlies, CAA, and radiational cooling will allow wind chills to fall into the lower teens Wednesday night. This is hazardously cold weather. A Cold Weather Advisory is likely to be issued for this period. Similarly, as the large high pressure continues to expand and broaden over the Heartland, temperatures Thursday will be well below climatological norms with the entire area again falling well below freezing. Despite a slightly more relaxed pressure gradient, wind chills Thursday night will fall into the teens once again. This precarious cold weather with 8+ hours of below freezing temperatures may burst water pipes. Measures should be taken now to protect people, pets, pipes, and plants through Friday morning.

LONG TERM
(Friday through next Monday)
Issued at 330 PM CST Tue Feb 18 2025

The large high pressure overhead will keep precipitation clear at the start of the long range, however, advection becomes neutral leaving cold air in place into the weekend. That said, the severity will be moderated below hazard criteria, however, these below normal temperatures will pose issues to certain people, pets, and plants that are exposed without protection for an extended period of time.

The pattern becomes a bit more unsettled as guidance continues to indicate troughing to deepen across the western Gulf which may bring PoPs back into the forecast by late Saturday. At this time, confidence remains low this feature will lift inland and for now, hedge to keep more substantial PoPs offshore through Sunday when temperatures gradually lift back into the 60's for highs. As the pattern becomes slack with dry weather leading into the upcoming work week, temperatures will gradually moderate toward the lower 70's Monday.
