KMAF and KINK by 02/12Z, with tempo IFR ceilings expected Friday

.PREV DISCUSSION... /issued 315 PM CST Thu Dec 1 2016/


A glance out the window and at vis sat imagery shows a beautiful
fall day across West Texas and Southeast New Mexico, w/sfc obs
showing afternoon temps have warmed just a few degrees above-normal.
However, big changes are in store over the next 24-36 hours.  WV
imagery shows an upper-lvl trough digging south along the west
coast, w/models in good agreement in closing it off by 12Z Fri and
reaching the AZ/Mexico border by 00Z Saturday.  During this time, a
cold front will backdoor into the area Fri, and push SW into the FA
Fri night.  Large scale ascent ahead of the trough and weak
isentropic upglide is forecast to develop -RA along and behind the
front, w/chances increasing E-W Fri night.  As the trough digs
further SE into Sonora late Fri night, instability is forecast to
creep in from the SW, w/H7 LIs going negative over the SW zones
after 06Z Sat, and introducing isolated thunder into the mix.  This
instability is forecast to develop north and east during the day
Saturday, while cold air continues to advect in from the NE.
Forecast soundings over the Guadalupes get cold enough after 12Z
Saturday to introduce a rain or snow mention, w/the temp trace
riding the 0C isotherm from the warm nose to the sfc.  Soundings
suggest rain or snow thru at least 12Z Sunday, but accumulations
should stay out of advisory/warning criteria.  By late Saturday
night, soundings suggest a brief rain/snow mix in the higher
elevations of the Davis Mtns.  Friday night thru Saturday night,
high gap winds will be possible thru KGDP, and a watch has been
issued. Bottom line is that it is going to be a very wet and cold

Trough will continue digging deep into Sonora, then Chihuahua, and
then eject to the NE thru the Big Bend Region Sunday night, before
precip chances taper off Monday.  Temps should stay well-blo normal
during this time, and are not expected to climb back to above-normal
until Tuesday.  However, another cold front is due in later in the
week to take things back blo normal, although long range models
differ on timing.  Grids stay generally dry after Monday.
