NATIONAL WEATHER SERVICE GRAND JUNCTION CO
235 AM MST SUN MAR 31 2002

BENIGN NW FLOW CONTINUES TODAY THEN WILL STRENGTHEN MONDAY AS THE
SHORTWAVE ALONG THE BC COAST DROPS ESE. THIS FEATURE HANDLED BEST
BY THE AVN VORTICITY FIELD. WEAK SHORTWAVES FRI AND SAT EVENING HAVE
CAUSED OCCASIONAL DENSE CIRRUS AND BREEZES. ANOTHER WEAK SHORTWAVE
BRUSHES NE COLORADO TODAY.  THE TENDENCY IN THIS PATTERN IS FOR
ENERGY TO TRY TO UNDERCUT THE RIDGE SO EXPECT ANOTHER EVENING OF
BREEZES AS FAR WEST AS CANYONLANDS AIRPORT AND BLANDING.

DETAILS...DURANGO WAS UNUSUALLY WARM SATURDAY IN THE VICINITY OF THE
THERMAL RIDGE. RIDGE IN PLACE AGAIN THIS AFTERNOON SO WILL GO WELL
ABOVE GUIDANCE THERE. FOR MONDAY...GOOD 8-7 WARM ADVECTION PROGGED
FOR THE AFTERNOON SO WILL GO ABOVE GUIDANCE TEMPS.  WINDY CONDITIONS
FOR THE AFTERNOON...BUT BELOW ADVISORY CRITERIA.  TUESDAY...2C OF
COOLING FOR THE NORTH WITH LITTLE TEMPERATURE CHANGE SOUTH.
WEDNESDAY...NW FLOW CONTINUES ACROSS THE NORTH. IN THE SOUTH...CUTOFF
LOW BEGINS TO TRANSLATE THRU NM WITH SOME HIGH-LEVEL MOISTURE RETURN
INTO THE SOUTHERN ZONES. NO PRECIP EXPECTED. OTHERWISE NO CHANGES TO
EXTENDED WITH PREVIOUS DISCUSSION ATTACHED BELOW FOR CONTINUITY.
99/RAMEY

EXTENDED (WED-SAT)...DRY WEST-NORTHWEST FLOW ON WED. RIDGE BUILDS IN
THU-FRI. MID-LEVEL LOW/TROF UNDERCUTS RIDGE AND MOVES ACROSS SRN
CA/BAJA THU...AND THEN AZ/NM FRI. FLOW A LITTLE MORE ZONAL SAT AS
EAST COAST TROF LIFTS OUT AND ANOTHER SHORTWAVE MOVES ACROSS THE
NRN ROCKIES. LOOKS LIKE EASTERN UT/WRN CO WILL GENERALLY BE IN
BETWEEN THE NRN AND SRN WAVES...BUT SHOULD SEE THE RIDGE BRIEFLY
BREAK DOWN. MOISTURE APPEARS LIMITED SO WILL CONTINUE WITH THE DRY
FORECAST AND GRADUAL WARMING THU-FRI. MAYBE A LITTLE COOLER SAT AND
BREEZY ACROSS THE NORTH...BUT WILL NOT ADD MENTION OF WIND RIGHT NOW
FOR THAT FAR OUT. JAD

WESTERN COLORADO AND EASTERN UTAH EMERGENCY MANAGERS SHOULD MAINTAIN
A NORMAL LEVEL OF WEATHER AWARENESS TODAY.

.GJT...NONE.
