.DISCUSSION...
Issued at 1204 PM MDT Sun Jul 19 2026

Upper high still located over eastern Colorado and western
Nebraska/Kansas, with ridge extending down to western
Arizona/SoCal. Old cut-off low is pretty ill defined but looks to
still be over the Big Bend region. Plenty of moisture remains for
today (PWs of 1.20-1.40 inches); main issue will be if the
leftover clouds can dissipate. Mountain zones are already mostly
sunny and getting the first CU buildups of the day and the
northern lowlands look to be thinning out, while the clouds closer
to the border remain fairly thick. This could be related to a
possible MCV just southwest of El Paso. Various models (CAM and
hemispheric) have plenty of convection this afternoon and evening.
Expect scattered to numerous thunderstorms this afternoon, mainly
over mountains, with scattered evening storms all areas. Main
threat will be heavy rain and flooding. Also, though DCAPEs are
relatively low, severe, damaging winds are possibly near any wet
microbursts.

Monday and Tuesday...old upper low approaches El Paso Monday night
and moves to the Arizona border Tuesday afternoon opening up into
an inverted trough. Still expect plenty of convection Monday, and
with PWs mostly unchanged, flash flooding will still be a threat.
By Tuesday, best storm chances will be west of the RG Valley,
which will still continue with a threat of flash flooding.

Wednesday and Thursday...inverted trough moves out of our area
into Arizona. Any chance of rain will remain over the far western
CWA. PWs will approach 1.00 inch Wednesday and below Thursday, so
heavy rain/flooding threat should be done. Temperatures will
climb back to seasonal levels.

Friday through the weekend...turns dry with maybe just the
slightest of chances of thunderstorms over the mountains.
Temperatures will warm back above normal, with the lowlands back
100-105 degrees.

Issued at 1204 PM MDT Sun Jul 19 2026

thunderstorms again this afternoon/evening and again on Monday,
before the chance of rain moves out mostly over areas Deming west
Tuesday through Thursday. Temperatures will remain slightly cooler
than normal. For Friday into the weekend drier air moves in with
little or no chance of rain. Min RHs lower with lowland RHs
approaching critical. Temperatures will warm back above normal. No
