AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND JUNCTION CO
302 PM MST MON FEB 26 2007
...SIGNIFICANT WINTER WEATHER TO HIT EASTERN UTAH AND WESTERN
COLORADO TUESDAY AFTERNOON THROUGH WEDNESDAY NIGHT...
.SHORT-TERM (TONIGHT THROUGH WEDNESDAY)...
TONIGHT...SNOW SHOWERS DIMINISHED THROUGHOUT THE DAY. ONLY OROGRAPHIC
SHOWERS REMAIN AND THOSE ARE ASSOCIATED WITH A RELATIVELY
DISORGANIZED BAND...MAYBE A WARM FRONTAL BAND....THAT IS WAVING TO
THE NORTHEAST. SE UTAH AND SW CO ALREADY CLEARED OF PCPN AND MOST
CLOUDS. CENTRAL AND NWRN CO SHOULD SE THESE SPOTTY SHOWERS THROUGH
TONIGHT...BUT LITTLE ACCUMULATION IS EXPECTED. LATE TONIGHT...MODELS
STILL TRY TO INCREASE CLOUDS AND SNOW OVER THE SAN JUANS...BUT THERE
IS NOTHING ON SATELLITE OR IN THE RUC TO SUPPORT IT...SO EDITED MOST
OF THOSE OUT...KEEPING ONLY LOW ORGPHC POPS OVER THE HIGHEST MTS.
TUE AND TUE NIGHT...A STRONG TROUGH AND COLD FRONT MOVE INTO UTAH TUE
MORNING AND REACH NE UTAH AND NW CO TUE AFTERNOON. THE SYSTEM WEAKENS
SOMEWHAT TUESDAY WITH MODELS SHOWING 2 DISTINCT SHORTWAVES MOVING
THROUGH EASTERN UT AND NW CO TUE AFTERNOON AND NIGHT. AN AREA OF GOOD
FRONTOGENESIS AND INSTABILITY IS PROJECTED THROUGH THE NORTHERN HALF
OF THE FORECAST AREA TUE AFTERNOON THE MAIN UPLIFT AND SUPPOR FOR
WEATHER MAY SHIFT MORE TO THE SOUTH LATE TUE NGT...BUT SOME
UNCERTAINTY REMAINS ABOUT HOW MUCH CLEARING WILL OCCUR OVER NE UT AND
NW CO.
ON WED...NAM PRODUCES A CLOSED 700 MB LOW OVER UT AND MOVES IT ACROSS
CENTRAL CO...WHILE GFS TAKES THIS FEATURE THRU CENTRAL WY. BOTH
SOLUTIONS KEEP ALL THE INGREDIENTS FOR SIGNIFICANT SNOWFALL OVER THE
AREA. A FRONTAL BAND SEEMS TO STALL OVER CENTRAL CO WITH GOOD JET
SUPPORT ABOVE IT AND PLENTY OF MOISTURE AND OROGRAPHCIALLY FAVORABLE
WINDS.
HEADLINES...HAVE DECIDED TO GO WITH A WINTER STORM WATCH FOR THE
MOUNTAINS OF NE UT AND NW AND CENTRAL CO FOR TUE AFTERNOON THRU
WEDNESDAY NIGHT. WITH A LATER ARRIVAL OF WEATHER IN THE SOUTH...HAVE
ISSUED A WINTER STORM WATCH FOR THE MOUNTAINS OF SE UTAH AND SW
COLORADO TUE NIGHT THROUGH WED NIGHT. BELIEVE ALL THE INGREDIENTS ARE
THERE FOR A FOOT OF MORE OF SNOW IN THE MOUNTAINS DURING THAT PERIOD.
ALSO...700 MB TEMPS DROP TO -8 OF COLDER OVER THE NORTHERN HALF OF
THE AREA TUES NIGHT AND WED. A WINTER PRODUCE MAY BE NEED FOR UT ZONE
24 AND CO ZONES 1 AND 2.
.LONG TERM (WEDNESDAY NIGHT THROUGH MONDAY)...
THE GFS...NAM AND ECMWF WERE IN GOOD AGREEMENT TODAY.
WEDNESDAY NIGHT-THURSDAY: AS MENTIONED IN THE PREVIOUS DISCUSSION...
MODELS SHOWED COLD FRONT OVER THE SOUTHERN ZONES OF THE CWFA BY
EVENING. DIVERGENCE ALOFT ASSOCIATED WITH ZONAL JET JUST SOUTH OF THE
CO BORDER WILL INTERACT WITH THE FRONT TO BRING BEST CHANCES TO THE
SOUTH ON WEDNESDAY NIGHT INTO THURSDAY.
THURSDAY NIGHT-SATURDAY NIGHT: BUILDING RIDGE OVER THE WEST COAST
WILL CAUSE MOISTURE TO SHIFT NORTH WHERE OROGRAPHICS WILL PROVIDE
LIFT FOR CONTINUED SNOW ACCUMULATIONS IN THE CENTRAL AND NORTHERN
MOUNTAINS.
SUNDAY-MONDAY: FLAT RIDGE OVER THE AREA WILL BRING DRY CONDITIONS.
TEMPERATURES WILL BE COOLER THAN NORMAL BEHIND THE COLD FRONT AT THE
END OF THE WEEK...RETURNING TO NEAR NORMAL ON SATURDAY BEFORE RISING
TO ABOVE NORMAL SUNDAY AND MONDAY.
