.
SATELLITE ANALYSIS AND TRENDS...AREA OF PRECIP WHICH AFFECTED SRN
CA YESTERDAY MOVED INTO AZ SUNDAY NT..BECOMING BETTER ORGANIZED PER
FORMATION/EXPANSION INTO LARGE BAROCLINIC LEAF. DURING THE OVERNIGHT/
EARLY MORNING PERIOD LEAF EXPANDED ACRS N HALF OF AZ ACCOMPANIED BY
MOD/HVY SNOW. IN THE PAST FEW HRS..LEAF/CLOUD SHIELD HAS BEEN MOVG
EWD..BUT HAS ALSO BEEN EXPANDING AND SHOWING SOME CLOUD TOP COOLING
OVER NE AZ AND NW NM. CLOUD SHIELD CONTINUES TO SPREAD ACRS SE/S UT..SW
CO/NW NM AND HAS ALSO EXTENDED SEWD OVER AZ THRU E CENTRAL PART OF THE
STATE. GOES WV IMAGERY AND STLT WINDS SHOWS UPPR TROF EXTENDS ACRS GREAT
BASIN THRU W AZ AND IS MOVG EWD. STONG UPPR DIFFLUENCE IS NOTED OVER
NE AZ AND GENERAL VCNTY OF FOUR CORNERS..WHICH HAS BEEN CONTRIBUTING
TO RECENT CLOUD TOP COOLING MENTIONED ABOVE. WITH INCRG LIFT INDUCED BY
UPPR TROF AND DIVERGENCE WOULD EXPECT MOD/HVY SNOW RATES WHICH HAVE BEEN
OCCURRING OVER AZ WILL CONTINUE TO SPREAD ACRS FOUR CORNERS AREA..THRU
SW CO/NW NM. THIS COMBINED WITH DECENT LL JET AND WARM ADVECTION PER
12Z 700/850MB RAOBS..NAM FCST WIND ANALYSIS/ FCST..AND LATEST CLOUD TOP
TEMPS/SIGNATURE SUGGEST GENERAL 1-2"/HR SNOWFALL WITH SOME 2"PLUS/HR PSBL
AT TIMES. EXPERIMENTAL GOES DENDRITIC SNOW GROWTH ALGORITHM PRODUCT SHOWS
CURRENT AREA MOST FAVORABLE FOR HVY SNOW...WHERE UPWARD MOTION COINCIDES
WITH DENDRITIC SNOW GROWTH LAYER.. EXTENDS FM N HALF OF AZ THRU NW NM.
