SHORT TERM...
(Today and Tonight)

Near normal to slightly cooler conditions and dry weather will
continue for the area in the short term.

Another dry cold frontal passage will affect the area today.
Expect west to southwest winds this morning to shift to the north
in the Big Country by noon, then through the rest of the CWA by
late this afternoon. This will result in another day of highs near
60 for the Big Country. Farther south in the Concho Valley and
I-10 corridor, the front will have less impact, and temperatures
should be able to warm into the mid 60s. Models are in fairly good
agreement that dewpoint values will rise into the 30s tonight from
the current teens and 20s. For this reason, while we will have
favorable radiational cooling conditions with light winds and
clear skies, the dewpoint values may prevent temperatures from
cratering into the 20s. Have kept the normal southern valley areas
the coolest, with lows near freezing, and most other locations in
the mid to upper 30s.

LONG TERM...
(Thanksgiving Day through next Tuesday)

The forecast area will rest of the eastern flank of a broad upper
ridge over the southwestern CONUS Thanksgiving day with sunny
skies and afternoon highs in the 60s. A warming trend will
continue through the coming weekend with afternoon highs mostly in
the lower 70s. Morning lows will be in the 40s through the
weekend.

A weak dry cold front will push through the area Sunday night
into Monday with Monday afternoon highs cooling into the 50s over
the northern half of the CWA and lower 60s over the southern half.
Surface winds will quickly swing back to to south on Tuesday with
afternoon highs rebounding back into the 60s across the entire
forecast area. Nearly zonal winds aloft will back to the southwest
during the day on Tuesday in response to an upper level trough
moving over the California coastline. This Pacific low pressure
system may be the harbinger of our next chance of rainfall for
later in the week.
