.DISCUSSION...

Issued at 134 PM CDT Sun Sep 20 2026



Mid-level high pressure continues, of course, but there is the 

potential for slightly more interesting things happening at the 

surface. Low rain (15-25%) chances will return Monday as PWAT values 

reach 1.7-2.0" and outflow boundaries from storms to the north move 

toward the coast, colliding with the seabreeze. Low rain chances 

will continue along the seabreeze Tuesday. 



The NBM continues to indicate PoP values in the 20-50% range 

beginning Wednesday but, as the previous forecast mentioned, based 

on global models and understanding the NBM bias, expect these will 

continue to trend drier. South of the area, more moisture will 

result in higher rainfall totals. The NBM may be picking up on this 

and nudging it a little too far north. Either way, we'll keep an eye 

on this and update the forecast as needed.

.AVIATION...

(18Z TAFS)

VFR conditions are expected to prevail, though some periods of 

patchy fog will be possible at ALI. Relatively light winds will be 

expected through the TAF cycle.

Issued at 134 PM CDT Sun Sep 20 2026



Seas will decrease from 2-3 feet to 2 feet seas through Wednesday as 

light to gentle (BF 2-3) breezes continue. By midweek, gentle to 

moderate (BF 3-4) breezes will develop, with seas increasing to 3-4 

feet. A low to medium (20-40%) chance for showers and thunderstorms 

will develop midweek and continues.
