AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN ANGELO TX
405 PM CST Mon Dec 9 2013
Tonight and Tuesday
A colder airmass will continue to filter into the area overnight
as surface high pressure builds south across Texas. We will
eventually see drier air filter into the region late tonight,
which will scour out the stratus that currently blankets the
area. Weak ascent up and over the cold dome is resulting in some
patchy freezing drizzle this afternoon, mainly across the Big
Country. Patchy freezing fog is also occurring but visibilities
have been slowly improving this afternoon with most locations at
or above 2 miles. Currently have a Special Weather Statement out
until 4 PM this afternoon to mention patchy slick spots on mainly
bridges and overpasses.
Otherwise, some patchy freezing fog may linger into this evening
across northern sections. Skies are expected to clear from north
to south after midnight as the drier air begins filtering into the
region. Temperatures tonight will be cold with lows in the upper
teens and lower 20s. Skies will be mostly sunny on Tuesday with
light winds and warmer temperatures. Afternoon highs will range
from near 40 across the Big Country, to the middle 40s along the
Tuesday night through Monday
A cool week continues with a slight chance of showers late Thursday
Good radiational conditions, with clear skies and light winds, are
expected Tuesday night. Lows are expected in the mid 20s. Another
cold front Wednesday will limit a strong warm up. It, however, will
not bring as cold temperatures as the last 2 fronts. The front,
however, will keep low level moisture south of the region, and as
surface high pressure settles in, allowing temperatures to once
again drop back into the mid 20s Wednesday night.
A progressive upper low will move eastward from Baja California
Wednesday, opening up as it move across New Mexico and the 4 corners
region. The EC and NAM bring scattered light rain showers to West
Central Texas ahead of this system, Thursday afternoon into Friday.
The GFS model is mainly dry for West Texas, however the EC and NAM
are more optimistic for rain. Will continue a slight chance of
showers with this disturbance.
This weekend continues to look dry. A cold front will push through
Saturday, keeping temperatures down a few degrees. No precipitation
is expected, due to a dry atmosphere.
