Synopsis for the middle texas coastal waters -
weak to moderate onshore flow will continue as we wrap up the work week. Patchy fog is possible along the bays and the immediate coast Friday morning. With that said, we will have a small window this afternoon of moderate to occasionally strong flow, generally south of port aransas. A weak to moderate onshore flow will persist on Saturday. An upper level disturbance, cold front, and copious moisture will contribute to scattered to numerous showers/thunderstorms Saturday night. The front will move across the waters Sunday. In response, precipitation will dissipate and moderate offshore flow will develop creating small craft exercise caution conditions. Winds will transition to weak to moderate onshore areawide by late Monday and persist through the remainder of the period.

SHORT TERM
(Today through Friday)
Issued at 220 AM CDT Thu Apr 18 2024
Key Messages:
▶ Marginal Risk of Severe Thunderstorms across the Brush Country this afternoon/evening
▶ High Risk of Rip Currents extended through this evening
A couple elevated thunderstorms were observed passing through the Coastal Plains earlier this morning as a shortwave rotates through aloft. At the surface, onshore flow continues to usher moisture into the region. The 00Z KCRP sounding observed a PWAT of 1.51".
This will likely increase into the 1.7-1.8" range today. This will keep cloud cover in place through much of the short term period.
As we head through the day, a cold front will move south across the state, eventually stalling over the Hill Country. This boundary is expected to linger around Central Texas through the end of the work week. Meanwhile, another H5 shortwave will eject out of Mexico within the quasi-zonal flow aloft.
Lift associated with this wave and ample low level moisture will warrant a 20-30% chance of showers and thunderstorms. The greatest chances will be to our north where low level convergence will be increased closer to the front. With that said, the Brush Country remains within a Marginal Risk of Severe Thunderstorms through tonight. Any storms that do develop will be capable of large hail and damaging winds. Forecast soundings support this scenario with MLCAPE nearing 3500 J/kg, lapse rates around 8C, and bulk shear around 40 knots. In addition, DCAPE values range from 1000-1300 J/kg. A few recent CAM runs suggest a MCS moving south of out of the Hill Country tonight. The majority fizzle this activity out before nearing our northern counties. However, a few bring a decaying MCS into the Brush Country. Confidence is low but we will need to keep an eye on this trend. Any activity that does develop will likely diminish during the late evening hours as our upper level support exits to our east.
On Friday, the front looks to remain quasi-stationary to our north.
It will likely begin to move south once again towards the end of the short term as another shortwave across the Plains nudges it south.
There is a low chance for some patchy fog Friday morning as low level moisture continues to increase.
Lastly, went ahead and extended the High Risk of Rip Currents through this evening as buoy 19 is reporting swells around 8s with swell heights near 5ft. While some guidance is suggesting these swells to come down, it seems like it has been underdoing it recently so felt comfortable extending the high risk. There's a moderate risk tonight and Friday.
LONG TERM
(Friday night through next Wednesday)
Issued at 220 AM CDT Thu Apr 18 2024
Key Messages:
-Scattered Thunderstorms Saturday and Saturday Night
-Marginal Risk of Excessive Rainfall Saturday
The period begins with a boundary stalled in Central Texas that will get pushed through Saturday/Saturday night due to an upper level disturbance moving into the region from the west. This will combine with PWATs around the 99th percentile for this time of year (1.7-1.9 inches). Models also depict moderate instability in place across our area in advance of the front (GFS/ECMWF).
Therefore with accompaniment of the forcing from the upper level disturbance, scattered thunderstorms will be possible across the region Saturday into Saturday night. WPC put the northern portions of the CWA in a Marginal Risk for Excessive Rainfall. Given the moisture and instability it is not out of the question to get some heavier rainfall with these storms. After the passage of the boundary, conditions will begin to dry out though some moisture will linger Monday and allow a scattered chance for isolated showers along the Coastal Plains and portions of the Brush Country. A gradual warming trend will ensue after Monday high temperatures likely returning to the upper 80s to upper 90s by late next week.

Majority of sites are experiencing MVFR conditions this morning.
CRP/LRD have been bouncing between VFR and MVFR through the night.
VFR conditions return to all terminals by mid day as southeasterly winds begin to increase. Gusts from 20-25 knots will be possible this afternoon. Another round of low level stratus is expected tonight with MVFR gradually returning to all sites, except for LRD. There is also a moderate chance for IFR ceilings for the eastern 3 sites late in the night.
