SHORT TERM
(This evening through Saturday Night)
Issued at 411 PM CDT Fri May 17 2024

Rain continues this afternoon in a SW to NE line from Jackson County to Liberty County. Rain, for the most part, has remained south of I- 10. Will continue to monitor the potential for some stronger and isolated severe thunderstorms along the coast (SPC has a Marginal Risk out for the coastline). So far activity has not materialized into anything more than light to occasionally moderate showers. A couple of lightning cloud flashes have occurred. Storms over South Texas this morning and the inability for the environment to fully recover from yesterday's storms may keep the severe threat at bay.

Rain should taper off tonight as the trough exits and high pressure builds in...while sunny skies would normally be appreciated after the multiple events we have had in SE Texas this spring, the high pressure will send daytime highs to above normal levels through next week. Highs on Saturday will be in the upper 80s to low 90s. The combination of heat and humidity will lead to heat index values in the upper 90s to near 100F on Saturday, especially along and south of I-10.

To echo the last forecaster's discussion...hundreds of thousands of people remain without power, and based on the damage to power/transmission lines this could last for days, potentially even weeks. As high pressure builds in this weekend, it will kick off a pattern of hot and dry weather. Please make sure to check in on family, friends, and neighbors (especially those who are vulnerable). If you are using a generator, make sure to operate it outdoors in a well-ventilated area! Furthermore, a few things you can do to keep your home cool include keeping widows and doors closed and closing your blinds & curtains.

Stay safe, everyone.

LONG TERM
(Sunday through next Thursday)
Issued at 411 PM CDT Fri May 17 2024

The heat returns...it is imperative to take all safety precautions in the next several days. A major pattern change begins on Sunday as an upper level ridge of high pressure builds over northern Mexico/Southern Plains. Still appears that temperatures will peak after Tuesday as temperatures climb near the 99th percentile of climatology per NAEFS guidance. These percentiles continue to add confidence in the forecast for a period of hot and muggy conditions.
Highs into the low to mid 90s can be expected through the week.
These temperatures are near to slightly above normal for this time of year; however, the combination of hot and humid conditions will result in heat indices in the triple digits. Upper-level ridge axis shifts to our east by mid- week as an upper trough slides over the Rockies and pushes a frontal boundary across the central Plains. Latest deterministic solutions keep most of this activity north of the area; however, continued with some slight chances as some forcing may be present due to passing weak shortwaves. The best chance at seeing precipitation look to arrive towards the end of the week with the combination of the aforementioned frontal boundary and a parade of mid-level shortwaves.

Patchy fog cropping up for stretches across SETX, with SGR dropping as low as 1/2SM by 05Z. Still a mix across the spectrum from the LIFR at SGR to VFR, but still bring a mix of generally IFR or MVFR to most terminals tonight. Anticipate that VSBY will be quite variable overnight as it's been this evening, dipping to lower values for a time, interspersed with periods of improvement.
VFR emerges areawide in the morning, and holds with light/VRB winds for most/all of the forecast period.

MARINE
Issued at 411 PM CDT Fri May 17 2024

Scattered showers with a few storms will continue to move over the bays this afternoon, before moving offshore this evening/tonight.
Light to occasionally moderate north to northeast winds this afternoon will transition to the east and then southeast through the weekend. Dry weather and light to moderate offshore winds should persist through at least mid-week. Winds and seas will gradually strengthen/rise after mid-week as different disturbances move through.
