New AVIATION

SHORT TERM
(Today through Tuesday)
Issued at 243 AM CDT Mon Apr 28 2025

Key Messages:

- Moderate risk of rip currents today

- Above normal temperatures persists

Mainly settled weather is expected over the short term as high pressure is present in the mid-levels over central Mexico, accompanied by an expanding ridge across much of Texas and a developing mid-level low centered over northern UT. As these features progress over the next day or two, the ridge axis will slide further east with the low digging southeastward across the Desert Southwest ejecting several disturbances in the form of shortwaves/PVA. Despite the mid-level disturbances coming into close proximity to our CWA, PWATs around 1.20-1.35" are slightly below normal so have gone with very low rain chances in the way of silent PoPs.

Breezy to windy conditions are expected across the Coastal Bend and the Brush Country today and again tomorrow with sustained winds around 20-25 knots gusting up to around 30 knots in the afternoon hours. This is likely to result in beach and marine hazards in the way of increased risk of rip currents and Small Craft Exercise Caution conditions. Minor Coastal Flooding is possible but generally not expected as the P-ETSS is forecasting seas reaching around 1.7 feet MSL. Currently swell periods from Buoy 20 are at 8 seconds but if this increases to 9-10 seconds or more this may be enough to result in wave run-up to the dunes. Will monitor this throughout the day and issue any products if necessary.

Afternoon temperatures today and tomorrow will range from the low 80s along the immediate coast, mid 80s east to around 100 out west.
Overnight lows will hover around the low to mid 70s region-wide.

LONG TERM
(Tuesday night through next Sunday)
Issued at 243 AM CDT Mon Apr 28 2025

Key Messages:

- Shower and thunderstorm chances gradually increase from low to medium (20-45%) Wednesday through the weekend

- Widespread moderate risk of heat-related impacts Wednesday and Thursday afternoon with heat index values 90-105

An amplified mid-level trough over New Mexico will swing over the southern Great Plains Wednesday through Thursday morning before lifting northeast late in the work week as a mid-level trough deepens into a closed low over the Four Corners region. A series of shortwaves associated with these systems will pass over South Texas through this weekend. Additionally, a decaying cold front will approach or extend into the region Friday night into Saturday before retreating northward Sunday. Therefore, rain chances will start low (20%) Wednesday and Thursday with above normal moisture (PWAT around 1.5") and shortwaves but increase to medium chances (40%) Friday and Saturday due to even greater moisture (PWAT around 1.8") and the additions of a decaying surface front and inverted surface trough.
Although the front retreats Sunday, another negatively tilted shortwave drapes over and allows for lingering low (20-30$) rain chances. Kept equal chances for thunderstorms with CAPE at least 1500 J/kg during the day with mid-level and surface disturbances capable of breaking the 850mb cap. Conditions seem most favorable for thunderstorms Friday and Saturday when winds at 850mb shift more southeasterly, dampening the warm nose.

We'll have partly to mostly cloudy skies with highs ranging from the mid 80s to upper 90s Wednesday and Thursday (moderate risk of heat- related impacts with heat index values 90-105), before increasing rain chances help lower highs a few degrees Friday through Sunday with most noticeable improvement over the Brush Country. Lows will persist from the upper 60s to mid 70s. Southeasterly winds will persist sustained 15-20 mph daily, with a brief shift more easterly Friday night into Saturday in association with the decaying front.
The rip current risk will likely increase Thursday with swell periods around 8 seconds and persistent moderate onshore flow.
Please use caution if heading to the beach and remember, 'wave, yell, swim parallel.'

AVIATION
(12Z TAFS)
Issued at 617 AM CDT Mon Apr 28 2025

MVFR ceilings across eastern terminals this morning will become VFR by early afternoon. Southeasterly winds with gusts up to 25-30 knots is expected this afternoon/evening across the region. Tonight have MVFR ceilings across all sites with VCT/CRP and perhaps ALI with some IFR CIGs . Some patchy fog is possible but not confident enough to include in TAFs.

MARINE
Issued at 243 AM CDT Mon Apr 28 2025

A moderate to fresh (BF 4-5) onshore breeze this morning will be accompanied by increasing seas from 3 feet to around 5 feet by late tonight. Periods of Small Craft Should Exercise Caution conditions are expected, mainly across the southern waters/bays and offshore waters into mid-week. A fresh onshore breeze (BF 5)
will develop Tuesday night and persist through Wednesday morning before weakening to a gentle to moderate breeze (BF 3-4) Thursday through the weekend. There is low shower and thunderstorm chances of 20-30% Friday through the weekend.

FIRE WEATHER
Issued at 243 AM CDT Mon Apr 28 2025

Brief periods of elevated fire conditions expected as wind and humidity values will be approached this afternoon/evening with minimum RH values around 30% combined with around 20-25 mph southeast winds. Elevated fire weather conditions Tuesday are less likely with slightly calmer winds. ERC values over this area are in the 50-75th percentile. Breezy conditions Wednesday has a low chance of developing elevated fire weather conditions over western Webb County where afternoon relative humidity drops around or slightly below 30%; however, winds aren't expected to reach criteria along the Rio Grande. Otherwise, moisture will increase Thursday through the weekend, negating fire weather concerns with low shower and thunderstorm chances Wednesday through Thursday, increasing to medium chances Friday through Saturday.
