.DISCUSSION...
Issued at 200 AM MST Sun Dec 22 2024

Pleasant weekend of weather continues into Sunday with
temperatures well above normal for late December. Lowland highs
will reach the upper 60s this afternoon, and we may even see a few
70s. Broad high pressure over northern Mexico extends into our
area, diverting the polar jet track well to our north. Dry and
sunny weather today under light south flow.

Upper high breaks down early this week, retrograding west over the
Pacific Ocean. This will bring about a slightly more active
weather pattern through the rest of the year as the jet stream
track drifts further south and a progressive train of upper waves
pass by.

Deterministic models show the first weak wave passes through on
Monday, bringing an increase in cloud cover and surface wind shift
to the west. Temperatures will remain warm and no precipitation
is expected with this first wave.

Second wave is a bit stronger, depicted as a closed low moving
across northern New Mexico on Christmas Day. El Paso and southern
New Mexico will be on the southern end of this system, suggesting
another dry event along the International Border. NBM does have
low-end PoPs Wednesday night for the Gila National Forest, where
a light wintry mix is possible. Winds increase Christmas evening
as a Pacific cold front arrives, becoming somewhat breezy (peak
gusts in the 25-35 mph range). Temperatures fall a few degrees on
Thursday, closer to normal but still warm with lowland highs in
the lower 60s. Again this is all low-impact weather and no
headlines are expected, but at least something to discuss.

Third wave timed for late next week, around Friday. Again, slight
increase in westerly winds but continued dry conditions. Extended
models show high pressure building back in toward the end of 2024,
suggesting more warm and dry low-impact weather for New Year`s
Eve.

.FIRE WEATHER...
Issued at 200 AM MST Sun Dec 22 2024

Elevated fire danger today due to abnormally warm and dry
conditions. Temperatures will run 10-15 degrees above normal for
late December with min RH 10-20%. West winds 10 to 15 mph will
prevent any fire headlines. Smoke ventilation Poor to Fair with
transport due east.

Light west flow continues through much of a week ahead. Breezy
winds (gusts 25 to 35 mph) on Wednesday as a Pacific low passes
to our north. Minimal precipitation chances in place through the
rest of the year. Fuel moisture is near seasonal normals.
