.DISCUSSION...
Issued at 1217 AM CST Wed Nov 4 2026

Drier and slightly cooler wx is expected today into Thursday in the
wake of yesterday`s frontal passage. This front will lift back
north toward the coast as a warm front tonight and Thursday. Next
western trough, now situated over NV, will track ewd across CONUS
and push another cool front across the region late Thursday night.
Moisture recovery will be fairly limited...so rain chances should
generally be confined to coastal and offshore locations in
advance of the boundary. Fair wx, with sfc high pressure sagging
into the area, and a quasi-zonal flow aloft continues into
Saturday. Medium range guidance remains fuzzy in regards to how
the mid-upper pattern evolves into the late weekend and early
next week. Most deterministic data is trending toward some mid
level troffiness or a cutoff low evolving somewhere between Baja
and Louisiana (ha!) late in the weekend. Most guidance seems to be
pointing more to our west, but until data gets into much better
agreement I can`t add any additional value to the blended NBM
solution for the time being. 47

.AVIATION...
(12Z TAF Issuance)
Issued at 507 AM CST Wed Nov 4 2026

VFR conditions and light northwesterly to northerly
winds around 5-10 kt will prevail throughout the
forecast period. While there was a brief period of reduced
visibilities due to patchy fog at CXO a few hours ago, the
potential for another round is slim as drier air continues to
filter in behind yesterday`s cold front. Winds become light and
variable after sunset.

.MARINE...
Issued at 1217 AM CST Wed Nov 4 2026

Moderate north winds will continue into the early-mid morning
hours then diminish during the day progresses. Onshore flow will
resume tonight as the boundary moves back north as a warm front.
Another cold front, and scattered showers and isolated storms,
is forecast Thursday night. Moderate northeast winds will likely
continue through the weekend...perhaps increasing a bit as the
pressure gradient tightens.  47
