Area Forecast Discussion
National Weather Service SAN ANGELO TX
410 AM CST Tue Jan 17 2017

.SHORT TERM...
(Today and Tonight)

A weak cold front moved across the area overnight and will remain
well south of the area the next 24 hours. A closed upper low
currently over northern Mexico will lift northeast into New Mexico
by early Wednesday. Lift out ahead of the system will increase
across the area today, with moisture being lifted over the shallow
cool airmass north of the front. Scattered showers will develop
across roughly the southern half of the forecast area this morning
and spread north across the rest of the area this afternoon, with
precipitation continuing tonight and ending across far southeast
counties Wednesday morning. A few thunderstorms are also possible
through tonight but no severe weather is expected.

Precipitation amounts will range between 1/10 and 1/4 inch across
the northwest Concho Valley and the Big Country, with 1/4 to 1/2
inch elsewhere, highest over southeast counties. Temperatures will
be on the cool side today, with highs in the upper 40s to around 50
degrees, with lows tonight in the upper 30s and lower 40s.


.LONG TERM...
(Wednesday through Monday)

An upper trough/low will move toward the Central Plains Wednesday,
with clearing skies from west to east through the day. A few
lingering showers and thunderstorms are possible across mainly the
northwest Hill Country, although the majority of this convection
should be east of the region by noon. Highs on Wednesday will be
near seasonal normals, in the mid 50s to near 60. Overnight low
temperatures will mainly be in the low 40s.

A series of upper level troughs will track to the north of the
forecast area through the upcoming week. The aforementioned
trough/low will swing across the Central Plains late Wednesday into
Thursday, resulting in gusty west winds along with highs in the mid
60s to near 70. The next weaker upper level shortwave trough will
swing across the Plains Friday. Above normal temperatures and gusty
west to southwest winds are once again anticipated. Highs will be
very similar to what is forecast on Thursday, in the mid 60s to near
70. The next more potent upper level trough is forecast to track
across the Southern Plains late Saturday into Sunday sending a
Pacific cold front through the forecast area. Gusty northwest winds
of 20 to 30 mph are forecast on Sunday along with slightly cooler
temperatures. Highs will mainly be in the mid 50s to lower 60s.
Isolated to scattered showers will be possible Saturday into
Saturday night, although mainly dry conditions are forecast.
