SHORT TERM
(This evening through Tuesday Night)
Issued at 228 PM CDT Mon Mar 18 2024
I can finally write a relatively uneventful short term discussion! Many of you have seen the sunshine today. It has generally been a breezy, cool to mild day with temperatures ranging from the mid 60s to around 70. Mid/upper level Pacific moisture along with disturbances embedded in the SW flow aloft are throwing some cloud cover back into the picture this afternoon. The radar actually depicts the approach of widely scattered showers.
However, the LL atmosphere is extremely dry. Sfc dew points have fallen well down into the 30s (20s in some places). Could a few rain drops make it to the ground? Perhaps. But surface observations show that most of this rain is not reaching the ground. So expect the afternoon to remain dry in most communities.
A ~1032 mb sfc high over the central plains will push into Texas tonight, relaxing the pressure gradient and decreasing our winds this evening into the overnight. Meanwhile, the aforementioned clouds are expected to decrease in coverage overnight, especially over our northern counties. Temperatures will be rather chilly with overnight lows ranging from the mid/upper 30s across our northern counties to low/mid 40s along the I-10 corridor to around 50 at the coast. As high pressure begins its eastward drift on Tuesday, light winds will begin to veer eastward and eventually southeastward. Meanwhile, UL SW flow will continue to supply Pacific moisture to the upper portions of our atmosphere, resulting in increased cloudiness. Afternoon temperatures are expected to reach the low/mid 60s. The clouds coupled with light southeast flow from the Gulf should prevent temperatures from falling as much Tuesday night, with lows generally in the 50s (40s in our northern / northeast counties).

LONG TERM
(Wednesday through next Sunday)
Issued at 228 PM CDT Mon Mar 18 2024
The surface high pressure that was over the area on Tuesday has slid to the east on Wednesday ushering in moist southeasterly flow across SE Texas. Meanwhile, an upper level low will be swinging through the Desert Southwest into the Southern Plains on Wednesday. This system will start to bring showers and thunderstorms Wednesday night into our area, mainly west of I-45. SPC has placed parts of Burleson, Washington, and Brazos counties in a Marginal Risk (level 1 of 5)
for strong to severe thunderstorms for Wednesday night - though conditions look more favorable further west towards Hill Country. If an isolated strong to severe storm does form in our northwesterly area, the hail would be the main concern.
Showers and thunderstorm activity will increase across the area on Thursday as a coastal low begins to develop in the NW Gulf with areas along the coast having the highest coverage. The heaviest rainfall from this system is looking to set up offshore, but can't out rule some locally heavy rainfall along the coast leading to minor street ponding. WPC has placed the coastal areas in a Marginal Risk (level 1 of 4) for excessive rainfall on Thursday. The bulk of the rainfall will exit to the east by Thursday afternoon, but we could still see some isolated showers through Friday morning as the upper level low continues to swing through.
There will be a gradual warmup through the long term with high temperatures on Wednesday expected to be in the upper 60s to low 70s, then low to mid 70s Thursday and Friday. Weak ridging aloft but southeasterly flow at the surface will lead to a rather pleasant weekend with mostly clear skies with temperatures in the upper 70s to low 80s.

VFR conditions are expected through the period. Winds should gradually weaken after sunset. Light easterly winds can be expected Tuesday morning, then becoming south to southeast in the afternoon.

Issued at 228 PM CDT Mon Mar 18 2024
Moderate to strong offshore flow following yesterday's cold front will persist into this evening for the Bays and into tonight for the Gulf waters. Have been seeing gusts to 30 to 35kt at BOY019 the past few hours with seas up to 10ft reported. Small Craft Advisories are in effect until 4pm for the Bays and then 10pm for the Gulf Waters, but may need to be extended a few hours depending on how quick conditions improve. Nevertheless, small craft will need to at least exercise caution into Tuesday morning.
Onshore flow resumes Tuesday night and will continue through Thursday. Moisture will be increasing with the onshore flow, and there is a low chance of some patchy fog developing Wednesday night.
A coastal low will be developing in the western Gulf on Thursday causing widespread showers and thunderstorms in the coastal waters Thursday through Thursday night. Locally higher winds and seas will be possible near the coastal low.
Brief period of onshore flow is expected Friday morning in the wake of the departing coastal low, but then light onshore flow returns for the weekend with mostly clear skies.
