.AVIATION...
Broad shield of MVFR stratus will remain intact through tonight,
before eroding to VFR from SW-NE early Sun A.M. behind an upper
low tracking north of the terminals. At least one additional zone
of -RA will precede this low today, mainly affecting LBB and PVW
after 2 PM, but VIS restrictions are unlikely. CIGs tonight may
briefly eclipse IFR levels at times, but prevailing theme will be
MVFR with stiff N winds around 20 knots.

.PREV DISCUSSION... /issued 939 AM CDT Sat Apr 29 2017/

UPDATE...
Updated to lower temps this morning to better reflect a more
aggressive surge of cold air region wide, and to also insert
predominant light snow in NW Parmer County. Temps continued to
fall after sunrise with 32 degrees already in Friona at 9 AM. On
that note, METARs from Cannon AFB are already carrying light snow,
with FDX dual pol data indicating a similar scenario in northern
Parmer County. Recent call to Rhea (far NW Parmer County) had
light snow since 8 AM with a dusting on grass and visibility about
1 mile. Current indications are temps there should warm a few
critical degrees through the afternoon, before resuming a downward
trend with additional light snow this evening in the deformation
zone. Satellite imagery shows ample lift departing central NM
along the leading edge of a stout cold pocket (-25C temps 500mb
sampled from ABQ`s RAOB). Some break in precip is likely in our NW
zones later this A.M. before this cold pocket delivers a second
round of light precip to much of the Caprock this afternoon. At
this time, winter wx highlights are not expected this afternoon in
the far SW Panhandle as accumulations should be confined to
grass, but road conditions could easily deteriorate this evening
and overnight as temps lower below 32F for several hours. Will
continually revisit this potential through the day.
