.DISCUSSION...
Issued at 946 PM MDT Tue May 12 2026

Upper level high pressure is slowly making it way across New
Mexico tonight and into Wednesday. Wednesday looks to be the
warmest day of the week with high temperatures well above average.
A few locations in the lowlands will hit the triple digit mark.
El Paso will have a chance (20 to 30%) of hitting the triple digit
make as well. Late in the day the upper level ridge will be
moving off to the east and a short wave trough will move across
New Mexico. This system may have just enough mid level moisture
to get some thunderstorms going, but with the dry lower levels, it
would most likely be dry thunderstorms. The best chances for dry
thunderstorms will be in the Gila Wilderness.

For Thursday, yet another upper level short wave trough will
approach the region, but this system will also have a decent
lee side surface trough in southeast Colorado. Both of those will
give us a breezy to windy conditions with elevated fire weather
conditions. High temperatures on Thursday will run 5 to 8 degrees
above average. For Friday and Saturday, we will be dry with
afternoon high temperatures continuing to run 5 to 8 degrees above
average. Both afternoons will have breezy winds.

For Sunday we will still be dry and our high temperatures will be
running 3 to 5 degrees above average. Another upper level trough
will approach the Four Corners region Sunday afternoon. The
Sunday trough will be stronger than the other troughs, so we will
see windy conditions Sunday afternoon and with the warm
temperatures, blowing dust may also be a problem. For the start
of next week, we will still be dry, with less winds and high
temperatures running near seasonal averages.

.AVIATION...
(12Z TAFS)
Issued at 509 AM MDT Wed May 13 2026

isolated BKN070 -SHRA. Surface winds variable AOB 7 knots this
morning, becoming south 10-15G25 knots this afternoon, then

.FIRE WEATHER...
Issued at 509 AM MDT Wed May 13 2026

Fire conditions will remain elevated through the end of the
weekend as very dry air remains in place. A few light
showers/thunderstorms are possible this afternoon west of the RG
Valley, along with possible dry lightning. Otherwise little or no
chance of rain through the weekend and into the beginning of next
week. Humidity will gradually lower after Thursday with min
humidity mostly in the single digits by this weekend. Winds become
breezy Thursday, certainly elevating fire conditions. ERCs are
forecast to be past the 90th percentile this weekend across both
mountain zones. Combined this with gusty winds Sunday as a
Pacific frontal system moves through, and we could be looking at
critical fire conditions Sunday.

Min RH: Lowlands 10-15% today and Thursday, decreasing to 5-10%
Friday through Sunday. Mountains 12-20% today and Thursday,
decreasing to 8-15% Friday through Sunday. Vent rates very good-
excellent through Sunday.
