SHORT TERM
(Today through Sunday Night)
Issued at 319 AM CDT Sat May 18 2024
As you can imagine...our soils are fairly saturated given the multiple rounds of rainfall we've seen recently. Surface high pressure building in early this morning has allowed wind speeds to become calm. Couple that with skies becoming mostly clear in some spots allowing for temperatures to fall closer to the dew points in the upper 60s, and we have fairly favorable conditions for widespread fog development. Some of this fog may be dense at times and it is expected to last till around 9am Saturday morning, so be sure to exercise the proper precautions if you have plans to hit the roadways. A Dense Fog Advisory is in effect for portions of Southeast Texas till 10am CDT this morning. Once the fog burns off, our attention then turns to the upcoming period of above normal temperatures.
As an upper level trough exits to our east, upper level ridging begins to build in on late Saturday and marks the beginning of an extended period of hot and dry conditions. Drier air remains in place over the weekend though and that'll be coupled with not much of a breeze throughout the weekend due to a weak pressure gradient.
850mb temperatures will remain well into the 90th percentile through the weekend, so expect high temperatures mainly in the low 90s for Saturday and Sunday. Surface high pressure does shift eastward late Saturday allowing for light onshore flow to return. That's going to be more important going into next week with the bump up in humidity leading to more widespread heat index values in the triple digits.
Heat index values over the weekend will mainly be in the upper 90s, but some spots will be close to feeling like 100°F. Overnight temperatures will mainly be in the low 70s (and fairly muggy with maximum RH values greater than 95%). Speaking of that, model trends are pointing towards another night of patchy on Saturday night especially for locations along and west of I-45.
As of early Saturday morning, there are still 500,000+ of you without power around Southeast Texas (mainly Harris, Montgomery, and Waller Counties) from Thursday's storms. Unfortunately, due to the damage to power/transmission lines this could extend for multiple days/weeks. Today marks the beginning of an extended period of hot and dry conditions, so it is going to be important to have a way to stay cool. Be sure to check in on your family/friends/neighbors, especially those that are vulnerable, to be sure that they have ways to stay cool as well. Some cooling centers have been opened around the Houston area to offer relief to those without power, so be sure to find the closest one to you. Know the signs of heat exhaustion and heat stroke, especially as the cleanup process continues. If you are using a generator, PLEASE be sure to operate it outdoors in a well-ventilated area. A couple of tips for keeping your home cooler during the daytime: keep your windows and doors closed to prevent outdoor air from coming in and use blinds/curtains to keep the sunlight from entering. We hope that the power outages are resolved quickly for all of you. Stay safe, y'all.

LONG TERM
(Monday through Friday)
Issued at 319 AM CDT Sat May 18 2024
Little change has been made to the long term period. Heat will be the main weather story throughout this period as upper level ridging builds into the state from the south and southwest
For inland locations
we'll start with highs in an upper 80s to low 90s range on Monday followed by a couple days (Tuesday/Wednesday) with highs in the low 90s. We'll shave a couple degrees off the highs on Thursday as the ridge sags southward just a bit and allows for a disturbance/weakness to move eastward across the state and possibly provide areas generally near and especially to the north of I-10 with some shower/thunderstorm chances. The disturbance exits off to the east at the end of the week and allows those high temperatures to warm back up into a low to mid 90s range. As for lows, enjoy Monday morning while you can (readings in the upper 60s to lower 70s) because the rest of the week will be in the low to mid 70s. Heat index values throughout this forecast period will be in a 95 to 105 range, and all safety precautions should be taken. As of now, next Saturday looks like it could become our first Heat Advisory day of 2024, but do not wait until an Advisory is issued to exercise safety.

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.
