AREA FORECAST DISCUSSION

.DISCUSSION...
An upper low is located INVOF srn Calif with a rich mid/upper level
tap of Pacific moisture streaming nwd across the swrn CONUS. The
precip shield this morning was mainly out in the wrn CWFA closer to
the track of shrtwv trofs. Moisture has been/will be so rich (+3 to
+4 standard deviations per GEFS/NAFES) that it has/will keep temps
close to 32 in much of the GDPs, although temps are rising in the
GDP Mtns. Based on temps earlier and measured precip there could be
a couple of inches of snow up high, but Queen reports only rain and
GDP HQ reports light ice with FZFG. We will opt to let winter wx
advisory expire at 00Z. Overnight we expect that the precip shield
will expand as said shrtwv trof progresses ewd and as broad area
of lift resides over much of the region. Precip will mostly be in
the form of SHRA with isold embedded TSRA Sat PM. There is a slight
possibility of RA/SN/IP mix in nrn parts of Lea Co Sat AM. The chance
of precip is high, in fact widespread rain between .25-50" with
local amounts near or over an inch by Sunday morning when the chance
for precip starts to decrease. Local flooding will be possible. With
such high moisture content there will be narrow diurnal temp ranges.
A cold front will move thru the CWFA Sun AM as a nrn stream shrtwv
trof in cntrl plains drives it s, so even though precip ends Sun
it will still be cool. It could be even colder than MOS indicates.
Certainly cold by Mon AM with lows probably colder than MOS. A more
noticeable warm-up is not felt until Tue when lee trof/thermal ridge
return helping to push temps back into the 60s. Another front will
try to push thru W TX Plains Wed, but probably not until after
peak heating, thus colder Thur. Setting up to be warmer Fri (U50s)
with enuf of a NW mid level component for pressure falls and thermal
ridging.
