...New AVIATION...

.SHORT TERM...
(Tonight through Wednesday night)
Issued at 242 PM CDT Mon Apr 22 2024

Beautiful today with highs in the lower 70s under sunny skies.
This nice weather will continue into tomorrow, but with a warming
trend as highs bump up to the middle and upper 70s. SFC high
pressure remains elongated across the region Wed with mid level
heights rising. This will push highs into the lower and middle
80s, but with TDs in the middle 60s...not terrible.

.LONG TERM...
(Thursday through next Sunday)
Issued at 242 PM CDT Mon Apr 22 2024

The latter half of the week will be dominated by warm and humid
conditions more reminiscent of early summer than mid spring. High
pressure over the southeastern Gulf of Mexico will combine with a
pair of developing lows along the lee side of the southern Rockies
to produce persistent breezy southerly winds Thursday through
Sunday. NBM guidance presently keeps sustained winds a few MPH below
advisory criteria, but could still become necessary especially
Saturday.

Upper ridging extending from the Bay of Campeche across the western
and northern gulf will keep a lid on convection through Saturday
although waves of low and mid level moisture will yield more cloud
cover especially Friday. The ridge axis is progged to shift into the
Eastern gulf late Saturday, faster than previous runs, as another
disturbance pushes a frontal boundary toward the coast Sunday. This
looks to be our next significant chance of precipitation although
confidence on the timing of this system is very low due to poor
model consistency.

.AVIATION...
(00Z TAFS)
Issued at 616 PM CDT Mon Apr 22 2024

High pressure currently dominates the region and will continue to
do so over this TAF period. Winds at terminals are beginning to
show a turn to the southeast indicating high pressure moving to
the east of the region. This trend will continue, resulting in
winds becoming more southerly after 12Z tomorrow. As high moves
east, also expect winds to increase and/or remain a light breeze
over the period.

Dry airmass over the region will keep things clear and dry through
tomorrow evening. The only exception being very high clouds which
may stream overhead.

.MARINE...
Issued at 242 PM CDT Mon Apr 22 2024

SFC winds are generally from the east, but will turn onshore
tomorrow and continue through the work week. By mid to late week,
the pressure gradient increases with moderate onshore flow
likely.
