DISCUSSION...

An upper trough is centered over the Upper Midwest and extends
southward into Texas while another upper trough is moving over the
Pacific Northwest.  This upper pattern has resulted in westerly flow
aloft.  Temperatures today are expected to be mostly in the 50s
across the area in the wake of a cold front that moved through last
night.

The upper trough centered over the Midwest moves just to the north
of the Great Lakes area while the trough over the Pacific Northwest
moves southeastward on Thursday.  Surface winds will become
southwesterly and temperatures Thursday afternoon will warm up to
around normal values.  On Friday, the upper trough over the western
conus becomes more pronounced and digs south into Mexico and is
centered over Arizona.  Height falls over the area due to the
approaching upper trough will lead to slightly cooler temperatures
on Friday.  Upper lift and moisture will also increase across the
area on Friday in advance of this trough so rain with isolated
thunderstorms will be possible across northern and eastern sections
of the CWA.

A cold front will move into the area Friday night and precipitation
chances as well as areal coverage will increase across the CWA. Low
temperatures Saturday morning are expected to be near the freezing
point across the Guadalupe Mountains so rain mixed with snow is
possible. The heaviest precipitation appears to be during the day on
Saturday areawide.  High temperatures on Saturday will be much
colder with highs mostly in the 40s behind the cold front.
Precipitation will continue across the area into Saturday night.  It
should mostly be in the form of rain but snow flurries mixed in
across the higher terrain remain possible.  Expect that there will
be a slight warm up on Sunday with precipitation chances remaining
across the area.

The models indicate that the precipitation will be ending by Monday
evening with temperatures warming up more on Monday.  Another upper
trough is expected to impact the region during mid week next week
with another cold front moving into the area.  For now the models
keep this next system mostly dry.
