.SHORT TERM...
(Today and tonight)
Issued at 238 AM CST Sun Jan 19 2025

It is much colder across the area early this morning as the arctic
airmass/cold air advection has arrived. Current temperatures are
in the mid to upper 20s. Wind chills were in the lower to mid
teens due to gusty north winds. Will keep the Cold Weather
Advisory going until 9 AM. It will be very cold today and tonight
with highs only in the 30s and lows in the mid teens to lower 20s.
The wind chills will probably fall below 10 above across much of
the area late tonight due to gusty southeast winds. Going with a
dry forecast the next 24 hours.

.LONG TERM...
(Monday through Saturday)
Issued at 303 AM CST Sun Jan 19 2025

The work week kicks off under a very cold airmass settled in over
the area through Wednesday morning, with sub-freezing overnight
low temperatures in the mid teens to lower 20s throughout this
time period. With breezy winds expected Monday morning through
Tuesday morning, wind chill values are expected to drop into the
lower teens to single digits across much of the area early Monday
morning, Tuesday morning, and again on Wednesday morning. As a
shortwave disturbance begins to work its way through West Central
Texas Monday afternoon through Tuesday morning, models are showing
decent lift and low to mid-level moisture available to result in
precipitation developing. With these colder temperatures in place,
we are expecting this bout of precipitation to fall primarily as
light snow south of the I-20 corridor.

For the second half of the week, temperatures should gradually
warm back up to the 50s as the coldest airmass retreats to the
north. However, models continue to show a series of upper-level
troughs passing through the eastern half of the country during
this time with potentially another cold front on Thursday.
Conditions for the rest of this week will depend heavily on how
quickly this arctic airmass gets eroded on Wednesday and
Thursday.
