AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND JUNCTION CO
918 PM MST TUE MAR 29 2005
UPDATED TO ADD ZONES 9 AND 18 TO THE WINTER WEATHER ADVISORY.
.SHORT TERM (TONIGHT THROUGH THURSDAY)...CLEARING SKIES MOVING IN
BEHIND REMNANTS OF THE COLD FRONT THAT PLAGUED THE WESTERN COLORADO
FOR MOST OF THE DAY. PRECIPITATION AND CLOUDS OVER THE CWA ARE SLOWLY
DISSIPATING AS THE MAIN CONVECTIVE AREA MOVES EAST TO THE FRONT
RANGE. ENOUGH SNOWFALL APPEARS ON RADAR TO CONTINUE THE ADVISORIES
FOR ZONES 9...10...AND 18 UNTIL EXPIRATION TIME...6 PM.
CLEARING SKIES WILL BE BRIEF THIS EVENING AS THE NEXT STORM IS
POISED O MOVE IN. THIS STORM HAS BETTER OROGRAPHICS THAN TODAYS
SYSTEM...BUT NOT AS MUCH DYNAMICS. THE MODELS DONT SHOW ANY HINTS
THAT THIS NEXT SYSTEM WILL STRENGTHEN AND STALL OVER COLORADO AS DID
THIS MORNINGS STORM. IT APPEARS TO HAVE ENOUGH MOISTURE AND IS COLD
ENOUGH TO JUSTIFY A WINTER WEATHER ADVISORY FOR THE MOUNTAINS OF
NORTHERN COLORADO AND NORTHEAST UTAH. WILL GO FOR A BROAD 6 TO 12
INCHES IN CO ZONES 3/4/ AND 13 AND UT ZONES 23/25.
WEDNESDAY AND WED NIGHT: THE MAIN PUNCH OF THE STORM SHOULD LAST
THROUGH THE MORNING...THEN IT SHOULD DIMINISH THROUGH THE AFTERNOON.
FAST CLEARING SHOULD RESULT IN QUITE COLD TEMPERATURES OVER THE
WESTERN HALF OF THE CWA WED NGT. HAVE GONE AT OR BELOW COLDEST
GUIDANCE IN GENERAL. THERE SHOULD BE A GOOD CHANCE OF FROST
OVERNIGHT.
THURSDAY...STRONG RIDGING AND DRY...NORTHERLY FLOW MOVE IN THURSDAY.
THE AREA SHOULD SEE PLENTY OF SUN BY THURSDAY AFTERNOON. HAVE GONE
NEAR THE WARMEST GUIDANCE TEMPS.
LONG TERM (THURSDAY NIGHT THROUGH TUESDAY)...
THURSDAY NIGHT-SUNDAY: AS THE PERIOD BEGINS...UPPER RIDGE MOVES OVER
THE GREAT BASIN TO THE NORTHERN ROCKIES RESULTING IN GOOD NORTHWEST
FLOW OVER THE FORECAST AREA. FLOW RELAXES AND BECOMES WEST BY FRI AS
RIDGE AXIS MOVES OVERHEAD AND FLATTENS. WARMING TREND BEGINS BY FRI
CONTINUING THROUGH THE WEEKEND AS DRY CONDITIONS PREVAIL. TEMPS WILL
CLIMB TO ABOVE NORMALS BY THE WEEKEND.
SUNDAY NIGHT-TUESDAY: THE FLOW BECOMES MORE WESTERLY AS A SHORTWAVE
TROUGH MOVES ONSHORE OVER THE PACIFIC NORTHWEST. THE EC AND GFS SHOW
GOOD AGREEMENT IN TIMING/STRENGTH WITH THEIR 29/12Z RUNS (BETTER THAN
PREVIOUS RUNS). STILL LOOKS LIKE MOISTURE WILL BE LIMITED AND EXPECT
THE SOLUTION WILL CONTINUE TO EVOLVE...SO HAVE NOT INCREASED POPS
WITH THIS PACKAGE. AT THIS TIME LOOKS LIKE BEST TIMING IS FOR MON
WITH FAVORED AREA OVER THE NORTH. DRIER CONDITIONS FOR TUE AS TROUGH
MOVES EAST.
