light onshore flow and low seas will continue through Thursday. The onshore flow begins to strengthen Thursday night into Friday morning ahead of some approaching weak disturbances. The winds will strengthen to around 15 to 25 knots with occasion higher gusts, so small craft may will likely need to exercise caution as early as Thursday night and small craft advisories may be needed heading into the weekend.

SHORT TERM
(Today through Wednesday Night)
Issued at 357 AM CDT Tue Apr 23 2024

For the most part, not a lot issues are expected for the short-term as the weather remains generally quiet/dry across SE TX. Flat zonal winds at the mid/upper levels are progged to become more northwest- erly through tomorrow as the next longwave trough approaches/begins to develop over the southern US west coast. This along with a deep- ening onshore flow at the lower levels here should result in warmer temperatures the next couple of days (and beyond). Additionally, we could also see some very isolated mainly afternoon showers tomorrow.
But, not at all confident with this scenario at this time given the building ridge aloft.

As for temperatures, the warming trend will continue. Highs will be in the upper 70s to around 80 today...lower to mid 80s on Weds. Low temperatures will run similarly
lower to mid 60s tonight
mid to upper 60s Weds night. 41

LONG TERM
(Thursday through Monday)
Issued at 357 AM CDT Tue Apr 23 2024

Summer creeps closer and closer during the long term as persistent southerly flow at the surface and southwesterly flow aloft bringing increasing temperatures and humidity. Afternoon high temperatures will be in the low to mid 80s on Thursday, mainly mid 80s on Friday, and then upper 80s Saturday through Monday. Dew points will be in the upper 60s to low 70s through the long term thanks to that moist, southerly flow, leading to heat indicies will be rising into the low 90s by Saturday. bleh. Overnight lows will see a similar warming trend with minimum temperatures upper 60s to low 70s Thursday night becoming low to mid 70s by the weekend.

The upper level ridge overnight will begin to break down on Friday allowing for some short wave to pass through the Southern Plains through the weekend. Main impact to SE Texas will be increased cloudiness, but can't out rule some isolated showers or storms making their way into the northern third (generally north of Conroe) over the weekend into early next week.

AVIATION
(12Z TAF Issuance)
Issued at 639 AM CDT Tue Apr 23 2024

VFR conditions will prevail through much of the day, with south winds (6-11kts) developing by this afternoon. As low-level moisture contin- ues to deepen, periods of MVFR ceilings (and perhaps some patchy fog)
will be possible tonight. Winds will decrease overnight to 4-7kts for most terminals. 41

MARINE
Issued at 357 AM CDT Tue Apr 23 2024

Light onshore flow and low seas will continue through Thursday. The onshore flow begins to strengthen Thursday night into Friday morning ahead of some approaching weak disturbances. The winds will strengthen to around 15-25kts with occasion higher gusts, so small craft may will likely need to exercise caution as early as Thursday night and Small Craft Advisories may be needed heading into the weekend. The increase in winds will also lead to an increase in seas to around 5 to 8 feet. Conditions improve into next week as high pressure build overhead.
