.SHORT TERM... (Tonight through Thursday night) Issued at 200pm CST Wednesday Feb 8 2023

The cold front was moving into Southeast Texas and was located along a line from near Galveston to 100 miles east of Baffin Bay as of ~3pm. A few showers will linger in the wake of the front over the coastal waters but should end in the next hour or so as drier air moves in. Skies are beginning to clear in the west with LRD and COT reporting CLR in their latest 21z observations. Expect clearing to commence from NW to SE through the evening hours with winds becoming light and variable as a weak surface ridge settles along the coast. Sounding profiles reflect a potential for fog overnight with dry air above a moist calm boundary layer. Fog should be most prevalent over the inland coastal plains and Victoria Crossroads area late tonight and early Thursday morning. Thursday should be a picture perfect day with abundant sunshine, light winds and temperatures in the 70s. But it won't last long as the next Canadian airmass is forecast to arrive around midnight Thursday Night sending temperatures back down into the 40s aided by strong north winds. Wind chills will fall into the mid 30s by Friday morning.

Long Term
(Friday through next Tuesday) Issued at 200pm CST Wednesday Feb 8 2023

Key Messages:

- Frontal boundary Friday morning and again Tuesday with breezy to windy conditions

- Small Craft Advisory is likely with gusts to Gale possible over the Gulf waters Friday morning

- Freezing temperatures and very cold wind chills Friday night across northern counties

- Elevated Fire weather conditions anticipated Friday afternoon and Tuesday afternoon

Not much change to the forecast in regards to Friday morning's cold front. The front is expected to move through South Texas early on Friday, reaching the coast by Friday morning about the time of rush hour. Breezy to windy conditions across the region with the highest winds along eastern sectors from Victoria Crossroads down to include the Gulf waters. Elevated fire weather conditions are possible briefly Friday afternoon as much drier air accompany windy conditions along the Coastal Plains, Coastal Bend and portions of the western Brush Country. After FROPA, expect ridging over the central CONUS over the weekend. The combination of freezing temperatures and winds early Saturday will result in wind chill values dropping to around 25-30 degrees across South Texas except for the island which will have a wind chill around 35 degrees. Wind chills Sunday morning will be a bit warmer but still around freezing mainly further inland.

Early next week, a transition period will give way to another mid- level low and another cold front as the low moves east across northern Mexico before swinging northeast over TX. Showers return beginning Monday ahead of Tuesday's front with isolated to scattered coverage across the region. Some isolated thunderstorms will be possible Tuesday morning but mainly over the northeastern counties and northern Gulf waters. Don't have much confidence in thunderstorms as CAPE values are expected to generally on the lower end with some of the GEFS ensemble members suggesting values may approach 600 J/kg. A look at deterministic model soundings don't support a favorable thunderstorm profile but have opted to leave in isolated thunderstorms over the aforementioned areas briefly. Not expecting much rainfall with generally less than 0.50" over the long term period. Breezy to windy conditions can be expected Friday and again to kick off the work week.

The good news or bad news depending how you look at it, is that temperatures this weekend remain on the cooler side with afternoon highs in the low to mid 60s then warming to the mid 70s to lower 80s by the middle of next week. Overnight lows Friday night in the low to mid 30s will climb back to the mid 50s by Monday morning. Mostly clear skies will follow behind each front with increasing clouds with the return of onshore flow.

Marine
