SHORT TERM
(Tonight through Saturday night)
Issued at 310 PM CDT Fri Apr 19 2024

Key Messages:

▶ Marginal Risk for Severe Thunderstorms across northern counties tomorrow

▶ Moderate Risk of Rip Currents continues into the weekend

Not much happening today weather-wise as persistence has a strong influence thanks due to a zonal mid-level flow and a northerly jet stream. With that said, rain chances are low (<25%) for rain/storms tonight out west where CAM guidance is once again trying to spin up an MCS overnight just west of our CWA over MX then moving east into Webb county where the environment is currently conducive for strong thunderstorms with CAPE around 2,000 J/kg and 0-6 km Bulk shear around 40 knots. The question remains if we can overcome the CAP. Confidence is low that a MCS will hold together as the system moves from west to east near our northwestern CWA border. The supportive environment quickly erodes during the late evening hours as shown by Model Sounding CAPE values dropping below 500 J/kg.

Tomorrow should start out fairly quiet ahead of the front that's progged to move through during the evening/overnight hours.
Shower/storm activity will ramp up as the front approaches the region through the day Saturday. Expecting a moderate chance (50- 70%) for storms/showers to develop by early evening, generally north of US HWY 59. Expecting FROPA between 00Z Sunday to around 09Z when the front should reach the coast. The environment will be marginally conducive for strong to severe thunderstorms with damaging winds and large hail of at least one-inch expected mainly across the northern tier of our region.

Temperatures: Today will top out in the 80s to mid 90s out west.
Tomorrow will be a little cooler with highs in the 80s to low 90s.
Overnight lows tonight will bottom out in the mid 60s to low 70s with lows in the mid 50s-60s tomorrow night.

Hazards: Strong to severe thunderstorms may result in damaging winds and large hail of at least 1.0 inch.

LONG TERM
(Sunday through next Thursday)
Issued at 310 PM CDT Fri Apr 19 2024

Key Messages:

- Sunday and Monday are shaping up to be pleasant with cooler and drier conditions.

- Warming trend through next week.

After a few lingering showers and thunderstorms Sunday morning, mainly along the coast and over the coastal waters, cooler and drier air will filter into S TX on Sunday as high pressure builds across the region in the wake of a cold front. Temperatures Sunday are expected to be around 15 degrees cooler with highs generally in the low to mid 70s. Clouds will decrease throughout the day along with breezy northerly winds. Winds decrease through Sunday night with lows dropping into the 50s to around 60. Pleasant conditions continue Monday with highs a couple of degrees warmer as surface winds become onshore and begin to usher warmer moist air into the region.

The remainder of next week will continue to warm up into the 80s and 90s with ridging across the region and strengthening low level southerly flow.

A mixture of VFR to MVFR conditions is ongoing across area terminals. Eastern sites are forecast to fall into IFR levels temporarily by early Saturday morning. A few showers and thunderstorms will be possible through the night as a mid level disturbance moves through the region. Convection is expected to increase in coverage as we head into Saturday afternoon/evening as a cold front slides across the area. Sites will return to VFR during the afternoon hours on Saturday, but will drop back into MVFR levels as the aforementioned boundary approaches the area heading into the evening period. Winds will generally be light to moderate out of the east, then winds will shift around to the northeast behind the boundary Saturday night.
