generally moderate onshore flow will persist into the weekend. Winds and seas will periodically increase enough for caution flags. One of those periods happens to be now through early Friday morning with 15 to 20 knot winds and seas around 5 to 6 ft in the offshore waters. The persistent onshore flow will bring an elevated risk of rip currents into early next week.

SHORT TERM
(Today through Friday Night)
Issued at 304 AM CDT Thu May 23 2024
Strong, broad ridging extending from the Eastern Pacific-Mexico- Western Gulf of Mexico will hold tough. Mainly zonal/westerly flow on its northern periphery (locally) with subtle disturbances passing through from time-to-time. H85 temps 20-22C and H7 temps 10-14C will put a damper on rain chances for most of us today & Friday.
Exception could be our northernmost counties in the Brazos Valley and Piney Woods where conditions won't be quite as hostile. Global and hires guidance indicates opportunities for some isolated to scattered convection. First chance possibly today in association with a subtle impulse(s), differential heating, and maybe any remnant outflows left over from yesterday evening's storms. Second chance might come late Friday afternoon or evening where several models indicate a cluster of convection initiating on parts of the dryline in nctl Tx. Can't rule out the possibility of a few strong- severe cells, but looks like areas just north of the CWA would see the better possibilities at the moment.
Otherwise, continued summerlike conditions prevailing into the end of the work week with daytime highs in the lower 90s and overnight lows 75-81. Winds in the 10-20mph range should at least provide a touch of relief during the day. 47

Well you can't spell Houston without "hot" and that's going to be buzzword throughout the holiday weekend (especially Memorial Day).
To help you prepare for these hot temperatures, I challenge you to get hydrated by taking a sip of WATER every time you see words that include hot or heat (including the two in the first two sentences).
An upper level high will continue to sit over northern Mexico through the weekend leading to persistent ridging, so nothing but hot and dry conditions are in store for us through late Monday. On Saturday, we'll still have a lingering frontal boundary to our west with the surface low centered in the Central Plains. With Southeast Texas in the warm sector of this surface low, we'll have enhanced low-level moisture transport leading to increased humidity. When you combine that with the increasingly southwesterly flow at 850mb leading to 850mb temperatures near their MAX percentiles (NAEFS/GEFS), and we have our first (mini) heatwave of the year.
Interestingly, this is occuring before both meteorological and astronomical summer...neat! The average first day of 95+°F temperatures for the City of Houston is June 13th, and if the forecast holds then we're going to reach that about two weeks ahead of the average. Suffice to say, this round of heat is unseasonably early.
High temperatures on Saturday will be in the low 90s with heat index values in the 101-106°F range. We turn up the heat a bit higher for Sunday with most inland locations topping out in the mid 90s for air temperature with heat index values in the 102-110°F range. Keep in mind that our criteria for a Heat Advisory is heat index values at or above 108°F, so Sunday will likely feature our first one of the year. We'll likely follow that up with another Heat Advisory on Memorial Day/Monday, which still looks to be the hottest day of the forecast period with air temperatures in the mid to upper 90s and heat index values in the 103-111°F range. Don't expect much of any relief during the overnight hours as it's going to be warm and muggy with low temperatures in the upper 70s to near 80°F.
Now let's talk about HeatRisk. Saturday through Monday most of Southeast Texas is outlined in a "Major" risk (level 3 out of 4), which means that this level of heat affects anyone without effective cooling and/or adequate hydration. This is occuring on a holiday weekend and we know that many of you have outdoor plans, so PLEASE be sure to practice heat safety to protect yourselves and your loved ones. Drink plenty of water, take frequent breaks from the sun, avoid strenuous outdoor activities during the hottest part of the day, wear loose/lightweight clothing, know the signs of heat stroke/heat exhaustion, and ALWAYS ALWAYS ALWAYS look before you lock your vehicle. Don't forget about your pets as well! If the ground is too hot for the palm of your hand, then it is too hot for their paws. Don't forget the sunscreen too!
Rain chances return on Monday night as a frontal boundary pushes into Southeast Texas. The best chance of seeing showers/storms will be north of I-10...oh and don't get too excited about that front.
While temperatures do look slightly cooler, we're only looking at dropping back into the low 90s. That's certainly better than the upper 90s though, and we'll have the added bonus of dew points in the 60s again. Rain chances beyond Monday night are still uncertain with another ridge building in. There is some potential for embedded shortwaves to push through the area, but if that'll be enough to overcome the subsidence remains to be seen. I was on the long term forecast desk yesterday as well and between yesterday and today...the rain chances have decreased for early next week (not counting Monday night).

A mix of VFR-MVFR-IFR ceilings across the region. These should all lift into VFR territory by mid to late morning. SSE winds should increase to 15-20kt during the day and settle back into the 7-12kt range tonight. Look for a return of MVFR stratus tonight, but forecast soundings indicate this might fill in a bit later than the previous couple days...probably after 6z for most terminals. WIll keep an eye on precip development (if any) near the CLL/UTS terminals today, but am not planning to include the mention at this time. 47

HYDROLOGY
Issued at 304 AM CDT Thu May 23 2024
Minor to major river flooding continues for parts of Southeast Texas, particularly along portions of the Trinity and Brazos rivers.
The Trinity River at Liberty will remain in major flood stage until further notice. The Trinity River at Riverside is forecast to continue on a downward trend from moderate flood stage into minor flood stage early Thursday morning. Last up for the Trinity River is Moss Bluff which remains in moderate flood stage and is expected to continue on its steady recession through the end of the week.
Along the Brazos River, there are three gauges currently in minor flood stage: Richmond, Rosharon, and Sugar Land. Richmond and Sugar Land have already reached their crests and are forecast to gradually trend downward...and Richmond is forecast to drop out of minor flood stage on Thursday morning. Rosharon on the other hand is still rising and is forecast to crest just below moderate flood stage on Thursday. As always, we will continue to monitor observations and trends.
Remember to heed any instructions from your local officials and to never travel through ANY flooded areas or roadways. TURN AROUND, DON'T DROWN. Please monitor updated forecasts via the NWS AHPS website and/or the new NWS NWPS webpage (https://water.noaa.gov/) as the river flood threat persists.
