moderate south to southeast winds and elevated seas will persist into the middle of the week. Both winds and seas will slightly diminish during the second half of the week. Wednesday night through Saturday, some fog could develop in the area. The next cold front is scheduled to push off the coast this weekend with northeast winds developing in its wake. Currently, the best timing for showers and possible Thunderstorms with this front will be Saturday night through Sunday morning.

SHORT TERM
(Today through Wednesday Night)
Issued at 244 AM CDT Tue Apr 16 2024
As onshore flow continues to pump in moisture from the Gulf, the pattern of warm & humid nights will persist. We'll be on a bit of a hot streak as we are at the beginning of an extended period in which we will not drop below the 70°F mark during the overnight hours. You might be saying "oh it's Houston so that's normal". That's kind of right...but also our normal temperature for this time of the year is right at 60°F, so we'll consistently be at least 10°F above that for most of the week. While there is a cold front moving through Texas currently, don't expect that to bring any relief to the mugginess.
An upper level low will continue to drift eastward through the Central Plains in the early morning hours. In the late morning hours, it begins to move northeastward which takes away the push that the front would need to push through our area. The end result is a stalling frontal boundary to our west, but we will see a surge of moisture as a result of convergence along the boundary.
PW values rise up to 1.6"-1.9" across the Brazos Valley.
Showers/storms look to advance beyond the frontal boundary with portions of Brazos Valley/Piney Woods catching the tail-end of this line. This'll likely just be isolated rain showers when they reach our area as a robust subsidence inversion layer from 850-750mb should prevent anything of significance from developing. It's worth noting that a 35-45 kt LLJ remains overhead throughout the day (weakens to 25-35 kt by the afternoon), so expect breezy southerly wind again today. Temperatures this afternoon will top out in the low to mid 80s. With winds becoming light tonight paired with dew point depressions of 0-2°F, there is potential for patchy fog to develop especially along and south of I-10. Overnight lows will be in the low 70s once again, and we may be warm enough to come close to a few record high minimum temperatures.
The flow aloft at mid-levels deamplifies on Wednesday and becomes more zonal. At 850mb, the flow aloft remains southwesterly allowing 850mb temperatures to reach the 19-21°C range which is near the 99th percentile (NAEFS/GEFS). Resultingly, temperatures on Wednesday afternoon will top out in the mid to upper 80s for all except those along the coast. Coastal areas will top out in the low 80s. Going into Wednesday night, there will be another surge of moisture with PW values climbing to the 1.5"-1.8" range. There'll also be an embedded shortwave passing through as well that could provide enough lift for some isolated rain showers, but a subsidence inversion layer persists along with drier air aloft. So, I've kept PoPs limited to 10% for now. I'll give y'all one guess on what the low temperatures for Wednesday night are...♬*cue final jeopardy music*♬ "What is the low 70s?" is correct!

Warm temperatures will persist until a cold front moves across the area in a Saturday night through Sunday morning time period (some rain is possible Thursday afternoon/evening and again on Friday night in the Brazos Valley-Piney Woods areas as weak disturbances skirt our northern counties). Thursday's and Friday's inland highs will be in the mid to upper 80s (coastal highs in the upper 70s to around 80). Saturday could be a couple degrees cooler (inland highs in an upper 70s to mid 80s range; coastal areas still in the upper 70s to around 80) as the cold front eventually enters the area and brings us increasing clouds and rain chances. The area's best rain chances are Saturday night through Sunday morning in association with the front, and we will also cool back down with Sunday's lows in the 50s/60s and Sunday's highs in the 60/70s. In the wake of the front (into Sunday night and Monday), some lingering showers are possible mainly near the coast and offshore as weak disturbances move across the area. Expect cool overnight lows Sunday night (mainly 50s) and a slightly warmer Monday (mid 70s to around 80).

MVFR CIGs ongoing this afternoon. Winds have (for the most part)
relaxed; however, still have a few sites across the area gusting to above 20 kts. Isolated showers possible this afternoon for CLL/UTS terminals. MVFR CIGs will continue into the evening hours with light winds contributing to potential IFR CIGs and patchy fog. Decreased VSBYs will be possible along and south of the I-10 corridor overnight into Wednesday morning.

HYDROLOGY
Issued at 244 AM CDT Tue Apr 16 2024
Only one River Flood Warning remains in effect as of early Tuesday morning. The Trinity River at Riverside (RVRT2) is still on an upward trend heading towards its crest in minor flood stage, and it will remain in minor flood stage through at least the end of the work week. The River Flood Warning for the Navasota River at Normangee (NGET2) was cancelled last night as it finally fell back into action stage after numerous days in minor flood stage. We'll be keeping an eye on the Trinity River at Moss Bluff (MBFT2) as its secondary crest looks to approach minor flood stage towards the end of the week. There are a few other gauges that have crested into action stage along the Brazos and Trinity Rivers.
