Synopsis for high island to the matagorda ship channel out 60 nm including galveston and matagorda bays
fetch of light to 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 intercoastal water way well into midweek and can make navigation difficult. The next cold front pushes off the coast late Thursday night and early Friday morning.

New AVIATION

SHORT TERM
(Today through Thursday)
Issued at 316 AM CDT Wed May 8 2024

Key Messages:

▶ A Heat Advisory is in effect today across Inland Kleberg, Inland Nueces, and Jim Wells Counties

▶ Moderate to Major risk of heat-related impacts with near record high temperatures Thursday

South Texas will remain under a quasi-zonal flow aloft for the short term period with a mid-level low well to our north and a mid- level high over western Gulf of Mexico. At the surface, an approaching dryline will result in light and variable winds from S to W today with onshore flow returning tonight. Winds will be light and variable Thursday as a weak cold front approaches the region. Elevated heat indices will result in dangerous heat Wednesday and Thursday.

Clearing skies will help surface temperatures rise and combined with low-level humidity will result in a pretty high (60-90%) chance for dangerous heat indices exceeding 110 degrees according to the HRRR ensemble for Wednesday. Thursday, the HRRR has a moderate 40-55% chance for heat indices greater than 110. A Heat Advisory has been issued for Nueces, Jim Wells and Kleberg Counties from 18z Wednesday - 00z Thursday. Locales outside of the Advisory area can expect Heat Indices of 105 to 109 both days for a few hours in the afternoon.

LONG TERM
(Thursday night through next Tuesday)
Issued at 316 AM CDT Wed May 8 2024

Key Messages:

▶ Weak cold front Friday morning

▶ Low (20%) chance of showers and thunderstorms Friday, increasing to a low to moderate (30-40%) chance Saturday through Monday

We open up the long term with some relief from the heat in sight. A cold front will be moving south across the state Thursday night into Friday morning. The latest suite of guidance still has some timing differences regarding FROPA. For now, it seems like a mid morning passage on Friday. However, the GFS brings it through by daybreak while the NAM12 is about 6-10 hours slower. Despite above normal moisture in place, our rain chances don't look too great on Friday.
Will carry a slight chance, generally across the Brush Country, as a H7 vort max ejects across the Rio Grande. The front looks to stall across our southern tier of counties or perhaps just to our south Friday night.

On Saturday, this boundary will retreat back to the north-northwest as a warm front. PWATs will climb to near 2" over the weekend in the wake of the warm front. A series of passing shortwaves will allow for a 20-30% chance of showers and storms on Saturday and a 20-40% chance of Sunday. As we head into the work week, the main trough will swing across the Plains. As the trough moves through, a surge of high pressure will nudge the boundary back our way. It's unclear how far south the boundary will drift at this time. Therefore, only have a 20-35% chance of showers and storms on Monday. We hang on to some low end PoPs through the middle of next week as the upper levels remain fairly active. However, moisture may be limited and could hinder our chances.

A much needed cool down is in store this weekend as highs looks to top out in the mid 80s. Unfortunately, this won't last long as temps quickly rebound by early next week with highs settling back into the upper 80s to around 100 degrees.
