98 degrees.

.DISCUSSION...
Issued at 255 AM MDT Wed Sep 25 2024

Overall, no major changes in the forecast from previous forecast
packages with quiet weather conditions and hot temperatures across
far west TX and southern NM over the next few days.

Strengthening high pressure a aloft will be the main feature
dictating the sensible weather conditions across the Borderland
Region through the period. High pressure will continue building in
across the Four Corners and Southern Rockies region through the day,
leading to quiet weather conditions and above average warmth across
the desert lowlands. High temperatures this afternoon will top out
in the low to middle 90s under mostly sunny skies.

By the Thursday and Friday timeframe, upper level low over IL/MO/KY
tri-state area will interact soon-to-be Hurricane Helene after it
makes landfall near the Big Bend Region of Florida. Once inland
during the Thu-Fri timeframe, Helene will be pulled northwestward
across the Ohio/Tennessee River Valleys rotating around the
aforementioned upper low (Fujiwhara Effect). These two systems
will basically rotate around one another, while strengthening and
deepening. This will ultimately help strengthen the upper level
high over New Mexico leading the anomalous warmth through the
weekend.

High temperatures will be the warmest Friday through Sunday with
Friday being the hottest. 98 degrees is currently forecasted for
Friday which would tie the daily record. The possibility of hitting
100 degrees is not zero, but confidence in that happening is LOW.
Regardless, it`s going to be abnormally warm through the week.

Looking ahead, upper level ridging over the region will remain in
place leading to above average temperatures and dry conditions.

.FIRE WEATHER...
Issued at 255 AM MDT Wed Sep 25 2024

Upper level high pressure over the region with warm/above average
temperatures and dry conditions will be the theme through the
weekend. Fire weather concerns are LOW to LOW-END ELEVATED each
afternoon, LOW-END ELEVATED for elevations below 7500 ft. High
temperatures will remain 5-15 degrees above the seasonal average
with Min RH values across the desert lowlands/Gila between 15-25
percent and 25-35 percent over the Sacs this afternoon.

As high pressure aloft becomes more established over New Mexico,
daily high temperatures will be 5-15 degrees above average with Min
RH values at or below critical thresholds Friday through early next
week.

Winds will remain light and generally out of east/southeast. Winds
over the mountains will be more terrain influenced, along with
following it`s typical diurnal wind flow regimes. Mixing heights
will range from 9000-13000 feet each afternoon with Good to Very
Good ventilation rates.
