SHORT TERM...
(Tonight and tomorrow)

..Cold night followed by seasonal temperatures for Tuesday...

Some areas will see a quick drop off in temperatures after sunset
with strong radiational cooling likely this evening. An area of
high pressure will move in from the northwest and settle over the
area. In response, winds will quickly become light and variable
overnight With dewpoint temperatures in the low to mid teens,
overnight temperatures will quickly drop. Looks like the I-10
corridor and the eastern parts of the Concho Valley will see the
coldest temperatures, with overnight lows in the low to mid 20s.
Across the Big Country and the I-20 corridor, models have a mid to
upper level cloud deck moving into the area by the late evening.
Latest water vapor shows upper level moisture beginning to move
into far western Texas, and visible satellite shows a thin band of
high clouds moving west across southern New Mexico. These clouds
will limit the amount of cooling overnight in these areas and
overnight lows will be in the low 30s. Expect plenty of sunshine
and light winds across the area on Tuesday. Highs will be in the
upper 50s to low 60s.

LONG TERM...
(Tuesday Night through Monday)

Looks like mainly quiet weather and mild temperatures through
Thursday. Aloft, quasi-zonal flow will keep West Central Texas dry.
Highs will be mainly in the 60s, with lows in the upper 20s and 30s.
Will go with slgt chance Pops across the extreme east and southeast
Friday and Saturday due to weak upper level support. Also, a cold
front will move south across the area Saturday, bringing slightly
cooler temperatures Sunday and Monday.

FIRE WEATHER...

In the wake of the morning cold front, northwest 20 foot winds will
remain at 15 to 20 mph, with higher gusts through the early
evening. In addition, minimum relative humidity values will fall
to 15 to 20 percent, resulting in elevated to near critical fire
weather conditiions. Portions of the northern and eastern Big
Country may briefly see Red Flag Warning (RFW) conditions, but
have opted to keep the Rangeland Fire Danger Statement in effect
for these areas.
