SHORT TERM...
(Today and Tonight)

Dry air moved in quickly yesterday evening behind the Arctic front,
which has limited the amount of precipitation we received overnight.
Temp/Dewpoint spreads of 15 degrees or more resulted in a lot of
evaporation of precip. Still, we are seeing some freezing rain early
this morning continuing from near Sonora through Junction and Mason.
Have cancelled most counties from advisories and warnings, but will
continue with a winter weather advisory for eastern I-10 corridor
through 9 am due to icing threat on overpasses.  Precipitation
should be east of the area by the afternoon.

Winds are starting to decrease, but will still see wind chills in
the single digits and teens this morning. The cloud layer will
continue to lift today, but we still will not see sun for most of
the area...other than possibly the northern Big Country. Highs today
will only reach into the 20s for most areas. We should start
clearing out tonight, but the clearing will allow temperatures to
drop considerably overnight. We are looking at lows in the lower to
mid teens areawide.  Would not be surprised to see a few single
digits by morning in low lying areas with light winds.

LONG TERM...
(Wednesday through Tuesday)

Primary concerns for this period are the continued freezing low
temperatures overnight on Thursday and Friday morning. However,
it appears as though there is no longer a chance for precipitation
until Saturday afternoon. At that time, a disturbance appears to
move across the Great Plains sending another cold front through
West Central Texas. The front will bring a slight chance for rain
southeast of a Richland Springs to Junction line. However, chances
remain low until better details emerge. Otherwise, we are looking
at a gradual warm up into the weekend with temperatures reaching
into the 40s on Thursday and then the 60s and 70s by Saturday and
Sunday. The cold front on Saturday will drop temperatures back
into the upper 50s to low 60s for the remainder of the period.
