.SHORT TERM...
(This afternoon through Wednesday night)
Issued at 211 PM CDT Tue Oct 3 2023

WV imagery shows the upper trough ejecting into the Northern
Plains this afternoon, leaving West Texas and Southeast New
Mexico under southwest flow aloft. At the surface, return flow is
sharpening up a dryline along the western CWA border,
foreshadowing a potentially busy late afternoon/evening.
Convection yesterday produced prolific rainfall over Southeast New
Mexico and adjacent areas of West Texas to the east, in addition
to abundant large hail. Highest reported QPF was 3.16" at
Seagraves, and MRMS measured up to 4.66" nearby. KMAF 12Z RAOB
came in w/a juicy 1.45" pwat, quite a ways above the
climatological mean of 0.85". VIS sat imagery shows a healthy cu
field already developing over the higher terrain, and CAMs suggest
initiation 18-19Z. Indeed, the first cell is going up south of
KMRF. Deep-layer shear over Southeast New Mexico is expected to
spread east and south this afternoon as the trough pushes into the
region. However, mid-level lapse rates don't look quite as
impressive as yesterday, suggesting large hail may be less this
afternoon/evening. High this afternoon should top out 5-7F above
normal.

Tonight, a 30+kt LLJ will keep the storms going through the
evening, w/CAMs hinting at developing a secondary, isolated line
behind the first. Mixing will keep overnight lows 13-15F above
normal. This will also back up the dryline against the higher
terrain.

Wednesday, thicknesses suggest temperatures should be about the
same as today's, but maybe a degree or so cooler. NBM initiates
convection along this feature early, as a cold front moves south
into the South Plains late afternoon. CAMs develop 40-60kts of
deep- layer shear into the afternoon, mainly over the northeast
CWA. As the front approaches, another round of severe weather
looks likely as the front approaches. This should carry into the
overnight hours as the front moves through. Lows will be 4-5F
cooler than tonight, but still well-above normal.

.LONG TERM...
(Thursday through Monday)
Issued at 211 PM CDT Tue Oct 3 2023

Thursday morning, the much-advertised cold front will have made it
to near the Pecos River, and will continue its swift southward
progression to the Rio Grande by early afternoon. Breezy
northeasterly winds can be expected with the front, along with
sharply cooler temperatures, with highs Thursday expected to reach
the upper 70s across northern areas and the higher terrain, lower
to middle 80s elsewhere, and 90s confined through the Rio Grande
Valley. In the wake of the front, temperatures will continue to
cool through Saturday, with highs Saturday likely to be some of
the coolest we've seen in some time, topping out in the upper 60s
and lower 70s for most of the region, with middle 70s along the
Rio Grande. Early morning lows over the weekend may even dip into
the upper 40s for portions of Southeast New Mexico, the northern
Permian Basin, and the mountain areas. Thereafter, temperatures
begin to moderate somewhat as the trough continues its eastward
progression and ridging builds to the west. By early next week,
temperatures will be in the lower 80s for most, warmer, but still
a little below normal for early October, a welcome change from the
above normal temperatures that seem to have become the "norm".

Precipitation chances continue through the first portion of the
extended, though will gradually shift southward with the
aforementioned front. The best chance for rain will be generally
along and south of I-10 and especially toward the Big Bend and Rio
Grande in association with a weak disturbance progged to move
across northern Mexico. There remains some uncertainty in the
northward extent of precipitation coverage given the drier post-
frontal airmass which would serve to stymie precipitation
potential. Have adjusted the NBM PoPs down accordingly in the
Thursday night-Saturday night time frame, given the NBM's
propensity to struggle with drying of lower levels synonymous with
strong cold fronts. Otherwise, not too much change was needed in
the extended, with dry conditions returning areawide by Sunday
afternoon.

.AVIATION...
(00Z TAFS) Issued at 550 PM CDT Tue Oct 3 2023

Models are on the fence about low clouds developing KMAF/KHOB
overnight, and we'll hold off a mention for now. Convection has
moved out of all terminal sites, but we're watching for a few ISO
TSRA in the vicinity of KFST over the next hour or two. TSRA will
continue to move off to the east before diminishing into the
overnight. Looks like another round of TS on Wednesday afternoon,
best chances from KFST to KMAF so have PROB30s included between 18-
00Z with less confidence farther west around KCNM and KHOB. Any
+TSRA on Wednesday has the potential for gusty winds and large hail.
