SATELLITE ANALYSIS AND TRENDS...COMMA HEAD IS REALLY STARTING TO TAKE
SHAPE ACROSS S CO TO THE N OF ANOMALOUS AND VIGOROUS MID/UPPER LEVEL
CIRCULATION CENTERED OVER NM AS FRONTOGENETIC FORCING BELOW 700MB AND
ESPECIALLY TOWARD 850MB INCREASES IN AREAS OF LOWER TERRAIN FROM S
CENT CO TO NE NM AND THE NW TX PANHANDLE. A PRONOUNCED AXIS OF LOWER
LEVEL WARM ADVECTION IS ANALYZED PARALLEL TO THIS COMMA HEAD FORMATION
WHICH HAS PROMOTED CONVECTIVE INSTABILITY LEADING TO EMBEDDED CELLS
WITH LIGHTNING ACROSS LAS ANIMAS COUNTY CO AND EVEN STRIKES DETECTED
AS FAR W AS ALAMOSA COUNTY CO. WHILE MUCH OF THE LOWER TERRAIN TEMPS
IN THE REGION OF S CENT TO SE CO ARE WELL ABOVE FREEZING, HAVE NOTED
AT LEAST 1 RECENT REPORT OF THUNDERSNOW FROM LA VETA MOUNTAIN (KVTP)
NEAR THE BORDER OF COSTILLA/HEURFANO COUNTIES. HAVE ALSO RECEIVED A
RECENT NESDIS SNOWFALL RATE PRODUCT JUST PRIOR TO 21Z WHICH INDICATES AN
AREA OF SNOW IN REGION ROUGHLY BOUNDED BY PITKIN-FAR NE MONTEZUMA-RIO
GRANDE COUNTIES WITH A FEW PIXELS WITHIN THE AREA REACHING HIGH IN THE
APPROX LIQUID EQUIVALENT CONVERSION TABLE TO OVER .15"/HR. IT IS TO BE
EMPHASIZED THAT THIS PRODUCT MEASURES WHAT IS HAPPENING IN CLOUD SO THERE
MAY BE SOME UNCERTAINTY WITH PRECIPITATION TYPE AT GROUND LEVEL. STILL
GIVEN THE SIGNIFICANT MOISTURE TRANSPORT AND INSTABILITY PRESENT WITH
LOWER LEVEL FLOW WRAPPING AROUND NM CIRCULATION AND FOCUSING ASCENT INTO
THE FAVORED TERRAIN OF THIS REGION, BELIEVE LOCALIZED VERY HEAVY SNOW
RATES ARE LIKELY, POSSIBLY ON THE ORDER OF 1"-2"/HR DEPENDING ON TEMPS
AT THE LOWER LEVELS TO NEAR AND AT THE SFC. FOR THE NEXT SEVERAL HOURS,
EXPECT AREAS OF HEAVY SNOW TO CONTINUE TO AFFECT THE FAVORED TERRAIN OF W
CENT/SW CO TO S CENT CO IN THE AREA HIGHLIGHTED IN THE NESDIS SNOW RATE
PRODUCT WITH A GRADUAL SHIFT OF THE HEAVIEST SNOW TOWARD THE FAVORED
ELEVATIONS FARTHER TO THE E AND SE OVERNIGHT MORE INTO S CENT CO WHICH
IS ALSO DEPICTED IN WPC DAY 1 HEAVY SNOW PROBABILITY GRAPHIC.
