GMZ400 356 Am Cdt Fri Apr 26 2024
Synopsis - A tight pressure gradient between a series of lows over the southern plains and a high off the east coast will allow for a prolonged period of strong and gusty southerly 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 through the weekend. 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 Sunday night)
Issued at 430 AM CDT Fri Apr 26 2024

The pattern for today into the weekend will see a series of low pressure systems move across the Southern Plains with a high over the western Atlantic ridging in from the east. This will allow for very warm and muggy conditions, along with quite breezy and gusty winds.

For today, consensus of short term guidance keeps sustained wind speeds for the most part at or below 20 mph. Therefore, a wind advisory will not be issued. At the moment, no pops are in the forecast, however will need to watch a short wave moving in from the west this afternoon to see if it kicks off any convection over Texas that may move toward the forecast area.

Gradient tightens further on Saturday into Sunday, and both sustained winds and gusts are expected to be higher. Have gone ahead and issued a Wind Advisory on Saturday from 9 am to 7 pm local for locations mainly along and south of the I-10 corridor where sustained wind speed will over 20 mph and near 25 mph with gusts over 35 mph.

Late on Sunday, the upper level ridge breaks down enough that a short wave will move into the region and push a weak frontal boundary toward the forecast area. During very late Sunday afternoon into Sunday night, very rich Gulf moisture will pool across the northwest portion of the forecast area with PWAT values between 1.6 and 1.8 inches, which is above the 90th percentile of SPC climo, and 100H-50H mean layer relative humidity over 75 percent. Lift from this short wave will help develop showers and storms across the northwest portion of the forecast area that will slowly progress to the east.

With the high moisture content, and instability, with CAPES over 2000 j/kg, some stronger convection with high rainfall rates may form. With progged slow storm motions, and flow becoming parallel to the 85H-70H theta-e ridge, some localized heavy rainfall may occur from very late Sunday afternoon into Sunday night.

LONG TERM
(Monday through Friday)
Issued at 430 AM CDT Fri Apr 26 2024

The longterm forecast period appears fairly busy with a series of weak disturbances set to move across the region. The first takes place Monday as a weak piece of trof energy extending from low pressure in north central US looks to swing over the northern Gulf states throughout the day. Fairly widespread showers and thunderstorms can be expected with its passage.

Remnant showers and isolated thunderstorms are possible Tuesday, Wednesday and again Thursday with increasingly weak disturbances moving overhead. When not dealing with precipitation, high pressure attempting to ridge in from the east over the work week will keep a strong feed of moisture into the area resulting in several days of hot, humid weather.

Temperatures slightly above normal are expected over the longterm period. High's in the low to mid 80s are expected Monday and Tuesday with rainfall keeping temps slightly in check. Wednesday and beyond look to top out slightly higher in the mid to upper 80s.

AVIATION
(12Z TAFS)
Issued at 616 AM CDT Fri Apr 26 2024

The main story during the forecast package will be very breezy south to southeast winds, sustained between 15 and 20 knots with gusts around 25 knots, that will only decrease slightly after sunset. The southerly winds will bring in plenty of Gulf moisture with MVFR ceilings through about 26/17z, then increasing to VFR ceilings through the afternoon, before lowering to MVFR again tonight.

MARINE
Issued at 430 AM CDT Fri Apr 26 2024

Onshore winds are beginning to increase across the coastal waters as gradient between a high pressure off the east coast of the US and a low pressure system east of the Rockies in the Southern Plains begins to tighten. This pattern will continue through the weekend with a tight pressure gradient over the northwest Gulf between a series of lows over the Southern Plains and a high off the east coast and will allow for a prolonged period of strong and gusty southerly 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 through the weekend.

The prolonged fetch and duration of the strong onshore winds will increase water levels along the coast. Currently tides are about 0.5 to 0.75 feet above predicted levels and are expected to increase to between 1.0 and 1.5 feet by tomorrow. Therefore, actual tide levels are progged to be above the 1.5 MHHW threshold for a coastal flood advisory during high tide on Saturday morning for lower southeast Texas and lower southwest Louisiana. These conditions will likely continue for the high tide Sunday morning and will probably extend further east also.

Winds are expected to decrease early next week as the high weakens off the east coast and no deep surface lows are forecast to form over the Southern Plains.
