Synopsis for high island to the matagorda ship channel out 60 nm including galveston and matagorda bays
fetch of moderate onshore winds will maintain somewhat elevated seas for the next several days. Mariners should note high flows from area rivers, creeks, and streams will lead to above normal water levels and strong currents in the bays and icww well into midweek and can make navigation difficult. There is only a slight chance of rain, if any, expected into midweek. Onshore flow should prevail until the next cold front pushes off the coast Thursday night.

New SHORT TERM, LONG TERM, MARINE

SHORT TERM
(Tonight through Tuesday night)
Issued at 303 PM CDT Mon May 6 2024

Key Messages:

- High risk of rip currents and Coastal Flood Advisory in effect through Tuesday morning.

Generally quiet weather conditions can be expected through the short-term period, although cannot fully rule out a stray shower.
Quasi-zonal flow aloft and a few ripples in the upper level flow could combine with enough available moisture to spark a few showers over the region on Tuesday, mainly out west. However, most of the moisture will be at the lower levels with dry air aloft and a strong cap building. Therefore, have maintained PoPs below a 10% and silent. Having said that, these conditions are more optimal for patchy fog formation overnight, both tonight and Tuesday night when the dewpoint depression drops.

Warmer temperatures are in store for tomorrow, with highs ranging from the mid 80s along the coast to near 100 degrees over portions of the Rio Grande Plains and Brush Country. If we add to this dewpoints in the mid 70s, heat index values could max out at or around 110 degrees briefly in the afternoon. A Heat Advisory is not in effect at this moment, as these conditions are expected to be localized and of a short duration. But, we will continue to closely monitor it on Tuesday in case an Advisory is required.
Aside from this, expect overnight lows to range in the 70s.

A Coastal Flood Advisory and a High risk of rip currents has been issued for the high tide cycle tonight along the Gulf-facing beaches of the Middle Texas Coast. Current observations at buoy 42019 indicate swell heights at 4 to 5 feet with swell periods between 7 and 8 seconds. Winds are forecast to remain below 15 knots offshore out of the southeast, but the high swells and periods could lead to minor coastal flooding and an increase risk of rip currents along area beaches, mainly south of Port Aransas.
These conditions are forecast to improve tomorrow as winds become more southerly, but a Moderate risk of rip currents is likely to persist.

LONG TERM
(Wednesday through next Sunday)
Issued at 303 PM CDT Mon May 6 2024

Key Messages:

- There is a moderate to major HeatRisk Wednesday and Thursday.

- A front Thursday night will usher in drier air and return temperatures to near normal for this time of year.

The long term forecast continues to be on track with very warm temperatures. Onshore flow will keep moisture streaming into the area which, combined with the very warm temperatures, will lead to heat index values of 100 across most of the area to near 112 across the inland Coastal Bend. Heat advisories will likely be needed.

Good news, though! While the Summer pattern has started, we get to hold on to a little bit of Spring this weekend. A cold front will move across the area Thursday night into Friday, leading to cooler (around 10 degrees cooler!) temperatures Friday and into the weekend. The cold front looks like it will stall over the area Friday and Saturday, leading to a low (15-30%) chance of showers and thunderstorms through the weekend. We'll keep our fingers crossed that we can finally see some rain.

AVIATION
(18Z TAFS)
Issued at 1227 PM CDT Mon May 6 2024

MVFR ceilings are expected to lift to VFR levels in the next few hours, remaining at VFR through this evening. Overnight, sites will return to a mixture of MVFR to IFR conditions. Poor aviation conditions will likely persist through the morning hours on Tuesday. Southeasterly winds this afternoon will continue to be gusty at around 20 knots. Winds will decouple tonight and become weak and variable by early Tuesday.

MARINE
Issued at 303 PM CDT Mon May 6 2024

Weak to moderate onshore flow will continue through Wednesday night. Periods of Small Craft Exercise Caution conditions can be expected tonight through Tuesday night, mainly over the bays and nearshore waters south of Port Aransas. Winds will diminish Thursday ahead of an approaching cold front. Winds will shift to the northeast Friday and Saturday, then to the east on Sunday.
There is a 15 to 30% chance of showers and thunderstorms through the weekend.
