SFC DEWPTS HAVE DROPPED ACROSS THE NORTHWEST PRECLUDING CONVECTION
THERE. I THINK THE CHANCE OF TSTMS THERE WILL INCREASE THOUGH AS
COLDER AIR ALOFT SPREADS OVER CWA DESTABILIZING THE ATMOSPHERE. WITH
THE UPPER TROF MOVING IN AS WELL AS THE SURFACE FRONT...
THUNDERSTORMS COULD GO ALL NIGHT. RECEIVED A REPORT OF QUARTER SIZE
HAIL FROM MAGDELENA AREA AND THINK WE COULD SEE SOME MORE THESE

MINUS 10C TO -12C AT H5 TOMMORROW AFTN BASED ON MODEL FCSTS AND THIS
MORNINGS H5 UPPER AIR CHART. DEWPTS STILL IN THE 40S AND 50S ACROSS
UT AND AZ. THUS...EVEN THOUGH IT WILL DRY OUT A LITTLE AT THE
SURFACE...ATMOSPHERE WILL STILL BE QUITE UNSTABLE TOMMORROW.

FOR FRIDAY NIGHT...BACKDOOR WINDSHIFT/FRONT FCST BY ETA. MAKES GOOD
SENSE WITH TROF MOVING SOUTH AND EAST THROUGH THE CENTRAL PLAINS AND
UPPER RIDGE MOVING INTO THE MTNOUS WEST. SFC CHARTS SHOW 40S AND 50S
DEWPTS ALL THE WAY UP INTO SW CANADA THIS AFTN. THINK MNTN OF TSTMS

SUBSIDENCE SPREADS IN FROM THE NW SHUTTING OFF ANY FURTHER SHOT OF
PRECIP. UPPER RIDGE TO DOMINATE SUN...THEN DRY WESTERLY FLOW ALOFT
