(Today through Tuesday afternoon)

WV imagery this morning shows an upper trough making landfall on the
west coast just north of the Bay Area.  This will nudge the ridge
over West Texas and Southeast New Mexico to the east today,
developing southwest flow aloft over the region.  Despite this, hi-
res models suggest highs this afternoon will be within a degree or
so of where they were yesterday...around 5 F above normal.  CAMs
also develop isolated afternoon convection invof the Davis
Mountains.

Tonight, a 30+kt LLJ develops as return flow increases, surging
boundary layer moisture into the area.  This, in addition to
increasing high cloud ahead of the west coast trough, will keep
overnight lows 8-10 F above normal.

Tuesday, the west coast trough ejects to the Idaho/Wyoming border by
00Z Wednesday. Thicknesses increase a little, adding 2-3 F to this
afternoon`s highs.  A dryline is forecast to develop west of the
CWA, and large-scale ascent ahead of the trough will combine
w/upslope flow to open a window for isolated afternoon convection
over Southeast New Mexico and areas to the south.  W/this synoptic
setup, deep-layer shear of 35-45 kts is forecast develop over much
of the area...more than has been present in some time.  Hail doesn`t
look to be a concern, as mid-level lapse rates are rather tepid, the
steeper rates to the northwest of the CWA.  However, increased
dcapes and dry subcloud layers/inverted-v soundings suggest a few
cells could approach severe levels due to damaging outflows.

.LONG TERM...
(Tuesday night through Sunday)
Issued at 249 AM CDT Mon Sep 16 2024

Heading into Tuesday evening, storms from that afternoon gradually
taper off during the night with a loss of daytime heating. As the
upper low moves off to the north, the upper ridge originally in
place amplifies over the southern Great Plains. Temperatures move up
into the 90s areawide for Wednesday and Thursday with the Pecos
River Valley reaching back towards the century mark. Lows stay well
above normal in the 60s to low 70s during the same time. Late in the
week and into the next weekend, another upper low nears the region
and the ridge flattens and shifts to the east. Temperatures dip
closer to normal, 80s to 90F during the day and 60s at night, with
increasing chances for rain. Plenty of moving parts in regards to
how the upper level pattern plays out, so much will change over the
next few days.

VFR conditions will prevail next 24 hours in return flow, gusty at
times in places during the afternoon. Forecast soundings suggest a
patchwork of cu late morning/early afternoon, w/bases starting ~
4.5-8 kft AGL. No convection expected.
