New AVIATION

SHORT TERM
(Tonight through Monday night)
Issued at 344 PM CDT Sun Apr 14 2024

The deterministic NWP model runs predict a progressive upper pattern, with a disturbance on the West Coast and N-S ridge over the central CONUS at the beginning of the period, and with the upper disturbance approaching the southern Plains by the end of the period. The bulk of the upper forcing will remain north of the CWA during the period. Although PWAT values are expected to be near to slightly above normal, strong CIN will preclude surface- based convection. Elevated convection is also not expected given the lack of upper forcing and the approximately 300 mb dry layer aloft.

LONG TERM
(Tuesday through next Saturday)
Issued at 344 PM CDT Sun Apr 14 2024

Key Messages:

▶ Medium chance (30-50%) of showers and thunderstorms this weekend

▶ Minor to moderate risk of heat-related through the work week

There is good model agreement with a weak cold front coming to a halt as it extends from North Texas to the Balcones Escarpment midday Tuesday, then retreats northward Tuesday night. There is a low chance of showers and thunderstorms along this front but for now stays north of South Texas, only including a silent 10% chance over the northern Victoria Crossroads. Moisture and 850-700mb temperatures above the 90th percentile will keep very warm and humid conditions in place through the work week.

An amplified mid-level shortwave from northern Mexico shifts eastward across South Texas Wednesday through Friday. There is weak model agreement on the shortwave progression over South Texas with the GFS and CMC passing through the day on Thursday, while the ECMWF lags behind and weakens it as it pushes through late Friday. Decided to keep a low chance (20%) of showers and thunderstorms over the Brush Country on Thursday.

Unfortunately, agreement has not been consistent from run to run as discrepancies become more apparent through the weekend. Both the ECMWF and CMC depict an amplified mid-level trough over the Midwest CONUS pushing a relatively strong cold front through South Texas Sunday morning; whereas the GFS has a more zonal mid-level pattern and a very weak cold front pushing through Sunday night. All in all, there will be copious moisture with PWATs near 99th percentile along with a nearby front and a series of mid-level shortwaves. This combination will lead to low chance (20%) of showers and thunderstorms Saturday, increasing to a medium chance (30-50%)
Saturday night into Sunday.

AVIATION
(00Z TAFS)
Issued at 629 PM CDT Sun Apr 14 2024

VFR conditions along with gusty winds to 25-30 knots will continue this evening before decreasing down to more moderate levels tonight. Unfortunately, as the winds decrease, ceilings are also expected to lower leading to MVFR conditions late tonight into tomorrow morning. By 12-15z, sites will slowly begin to improve to VFR and winds will once again increase to around 20 knots sustained with gusts to 30-35 knots. Due to the strong winds at the surface, low level wind shear is not expected to be issue during this cycle.

MARINE
Issued at 344 PM CDT Sun Apr 14 2024

Issued a Small Craft Advisory (SCA) for the southern bays until 01z Monday (per the NAM, lowest approximately 500ft becomes less than dry adiabatic by 00z Monday). Strong onshore flow is expected Monday afternoon/evening over at least the southern bays/nearshore waters, as an upper level disturbance moves across the southern Rockies, yet will defer to the mid shift to issue the SCA. Onshore flow will diminish to weak to moderate through the day Tuesday but seas will remain elevated over 6 feet through Tuesday morning. Seas subside below Small Craft Advisory criteria by Tuesday afternoon. Weak to moderate onshore flow will persist through Saturday. Shower and thunderstorm chances return Saturday and increase through the weekend as a cold front approaches the waters combined with well above normal moisture.
