GMZ400 337 Am Cdt Sat Apr 27 2024
Synopsis - A tight pressure gradient between a series of lows over the southern plains and a surface high off the east coast will allow for a prolonged period of strong and gusty southerly/onshore winds. Sustained winds are likely to be near or above 20 knots through the weekend with gusts over 30 knots. This, along with building seas to as high as 10 feet offshore, will bring about a long duration small craft advisory conditions through the weekend. Showers and Thunderstorms return over coastal waters late Sunday with elevated rain chances continuing into late Tuesday. The onshore winds will decrease early next week as the high weakens off the east coast and no deep surface lows are expected to form over the southern plains.

SHORT TERM
(Today through Monday night)
Issued at 313 AM CDT Sat Apr 27 2024

Breezy and cloudy conditions have continued into the overnight; the deep fetch of onshore flow bringing about dewpoints in the mid 60s to low 70s. We are sitting at 74/70 F here at the office, and even with the breeze, it feels deplorable outdoors.

Expect much of the same today as we saw yesterday, only with slightly warmer temperatures and higher winds. In fact, these higher winds will be the primary talking point in the Day 1 timeframe. Pressure gradient between high over the northeast GoM and a series of low pressures over the Plains states continues to tighten and thus will yield increases in winds today and Sunday.
Sustained winds 15 to 25 MPH with gusts to 35 MPH are expected today, primarily along and south of hwy 190. The Wind Advisory for this region continues.

Latest guidance keeps winds along the coastline elevated above Advisory criteria through the overnight, thus the Wind Advisory was extended until at least Sunday morning. A further extension into Sunday may be needed down the line.

The long fetch brought on by winds has caused a building of water along the coastline and into channels. Expect further rises of water during high tide cycles - about 7 to 10 AM currently. A Coastal Flood Advisory has been issued along the entire coastline (including Orange/Calcasieu) for the potential of flooding waters today and Sunday.

Rain chances return to northern zones late Sunday into Monday with the eastern edge of upper shortwave trof moving over east Texas. This feature lifts out before widespread convection can move into the CWA

A secondary trof moves directly over south Louisiana on Monday.
Strong tropical moisture flux combined with trof forcing will bring about widespread showers and a few thunderstorms - isolated severe storms possible. Moisture and forcing best align along and north of I-10 where 1 to 3 inches of rain are possible throughout the day Monday. A Marginal Risk of severe weather area-wide and Slight Risk of excessive rainfall for the Lakes Area (Marginal Risk elsewhere) have both been issued by the Storms Prediction Center and Weather Prediction Center, respectively. While we work to discern exact weather hazards Monday, continue to monitor forecast trends to start the next work week.

LONG TERM
(Tuesday through Saturday)
Issued at 313 AM CDT Sat Apr 27 2024

Unsettled weather pattern continues into the middle of next week with continued onshore flow creating warm/muggy days. Southern stream jet will remain situated across the region with several disturbances. Given the moisture/instability in place with the disturbances, daily showers/storms seem increasingly likely each afternoon. Highest POPs remain inland Tuesday/Wednesday, but likely CWA wide will see at least isolated.

Daytime highs are nearly a copy and paste forecast all next week in the middle 80s. Winds remain onshore from the S/SE and occasionally breezy.

By late week, there could be a frontal bndry that approaches the region, but confidence is low. If this were to occur, it could provide another uptick in POPs.

AVIATION
(12Z TAFS)
Issued at 606 AM CDT Sat Apr 27 2024

This TAF issuance primarily tracks with winds and ceilings.
Tightening pressure gradient between high over the northeastern Gulf of Mexico and strengthening low pressure in the Plains states is resulting in elevated winds over the region. Expect southeast winds to continue strengthening today, especially for coastal terminals. Sustained winds 15 to 20 knots with gusts 30 to 35 knots are expected throughout the afternoon. Winds may diminish slightly after 00Z tonight with the setting sun, however elevated winds with gusts are still expected through at least 12Z.

Ceilings across the region are currently hovering 1500 to 2500 ft.
As the sun rises, winds increase and mixing can begin, expect ceilings to rise to around 3000 to 5000 ft this afternoon. Once again as winds diminish after sundown (after 00Z), ceilings will fall and should prevail between 1500 and 2000 ft.

Sustained winds are likely to be near or above 20 knots through the weekend with gusts over 30 knots. This, along with building seas to as high as 10 feet offshore, will bring about a long duration Small Craft Advisory conditions through the weekend.
Showers and thunderstorms return over coastal waters late Sunday with elevated rain chances continuing into late Tuesday. The onshore winds will decrease early next week as the high weakens off the east coast and no deep surface lows are expected to form over the Southern Plains.

Long fetch combined with high tide will likely bring about high water and coastal flooding conditions along the coastlines and in the channels.
