UPDATE
Issued at 521 PM CDT Mon Mar 18 2024
Just issued a Coastal Flood Advisory for the immediate coast through midnight tonight. While we are coming out high tide, ~11s swells and Ekman transport (thanks for strong northeasterly winds)
are pushing water up our coast. Tide gauges are not quite indicative of coastal flooding. However, webcams paint a different picture as water is nearing the beach access roads in a few spots.
SHORT TERM
(Tonight through Tuesday night)
Issued at 331 PM CDT Mon Mar 18 2024
Key Messages:
- Showers/thunderstorms remain possible (low <20% chance) into this evening
- Small Craft Advisory remains in effect through the overnight hours
Showers and a few thunderstorms have been persistent across our CWA today as a 700 mb shortwave over the area interacts with above normal PWAT's. Activity should wane over the next few hours as drier air filters into the region from a reinforcing surge of high pressure north of us. Have silent PoP's from this evening through tomorrow, with a small window tomorrow morning with a very low chance for some showers over the Coastal Plains as a smaller disturbance moves across South Texas. Confidence is low for shower activity tomorrow as lack of moisture will be the limiting factor.
Afternoon temperatures today should top out in the mid 60s to low 70s with mostly cloudy skies. Overnight expect lows to dip into the low to mid 50s across much of the region with tomorrows highs ranging in the 60s.
LONG TERM
(Wednesday through next Sunday)
Issued at 331 PM CDT Mon Mar 18 2024
Key Messages:
-Thunderstorms medium chance (40-50%) Wednesday night
-Thunderstorms High chance (60-80%) Thursday morning
-Sea Fog low to medium chance (30-50% <5 SM) Wednesday night into Thursday morning.
Mid Term (Wednesday through Thursday)...High pressure centered over the Florida Gulf Coast will continue with the onshore flow for Wednesday with the around 1.00" PWAT values expected through the day. Scattered showers are expected to develop along the Coastal Bend from the south, as a 500 mb shortwave interacts with the onshore flow and the moisture. We are fairly capped so the vertical ascent looks to be limited, however, with a 30 knot LLJ showers will form. With the cap over the region, sea fog is possible as the dewpoints advect north into the southern nearshore waters and Bays.
However, The restriction of visibility looks to be limited with the NBM numbers of 30-50% that the vis will be below 5 miles. The dewpoints just start to peak to about the upper 60s, which is around the water temperatures. The cap looks to erode in the evening, allowing for better CAPE values, although, we lose the LLJ (20kts), so will expect scattered thunderstorms overnight, especially with 500 mb low, that has been stuck in Arizona, moves through the Panhandle and into Oklahoma, by Thursday morning. As the trough axis move through South Texas, the rain is expected to clear from West to East and be out of the Coastal Bend around 1 pm. Dry air then moves into the region Thursday night.
Extended (Thursday night through Monday)...Thursday night through Monday, the sfc high pressure builds into the region and the 500 mb heights build back a bit. So will expect that the chances for rain would be minimal through the extended period. However, Sunday, the high moves east bringing back the onshore flow, and a sfc low begins to spin up in Colorado and as it moves east, the chance for rain and probably thunderstorms begins to increase again. However, the chance pops are north of the forecast area. Winds do increase in the offshore waters with the tightening pressure gradient increasing the risk of SCEC or even SCA by Monday.
AVIATION
(00Z TAFS)
Issued at 605 PM CDT Mon Mar 18 2024
VFR conditions prevail through this TAF cycle. Northeasterly winds will continue to weaken through the evening and overnight hours.
Winds will regain a east-southeast component by late Tuesday afternoon. There is a low chance of MVFR ceilings returning at LRD towards the end of the period.
MARINE
Issued at 331 PM CDT Mon Mar 18 2024
A Small Craft Advisory is currently in effect through early morning with some occasional gusts to Gale. Isolated shower activity is expected to taper off this evening. Very Strong northeast flow is expected to continue through late tonight then becomes moderate tomorrow morning followed by flow veering onshore and weakening to weak levels tomorrow night. Isolated to scattered showers are expected Wednesday. There is a chance (30-50%) for sea fog to develop Wednesday evening. An upper level disturbance will contribute to scattered showers and thunderstorms Wednesday night and Thursday. Drier conditions expected Thursday night. Weak to moderate onshore flow expected Wednesday. Generally weak winds Thursday and Friday. Moderate to strong flow is expected early next week. This will likely warrant Small Craft Advisory conditions.
