AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER COLORADO
230 PM MST SAT MAR 25 2006

.SHORT TERM DISCUSSION...AN INCREASING SOUTHWESTERLY FLOW ALF WILL
DEVELOP TNGT AHEAD OF THE NEXT APPROACHING SHORT WAVE.  THIS SYSTEM
WILL MAKE ITS FM SERN ID BY 12Z SUNDAY INTO SWRN SOUTH DAKOTA BY 00Z
MONDAY.  BOTH MDLS SHOW A UPPER LEVEL JET MAX OF AROUND 110 KTS
MOVING ACRS NRN COLORADO THROUGH THE DAY SUNDAY.  BOTH THE NAM AND
GFS INDICATE SOME WEAK UPWARD QG OMEGA DVLPG OVER WRN CO AFTER 09Z
TNGT...WITH STG SUBSIDENCE DEVELOPING AFTER 12Z SUNDAY.  THE SNOW
THE FORMS LATE TNGT AND SUNDAY WILL BE MORE A PRODUCT OF STRONG
OROGRAPHICS AND FVBL MID LVL INSTBY (7-7.5 C/KM).  SNOW AMOUNTS FM 2
TO 6 INCHES STILL LOOK ON TRACK WITH THE BEST POTENTIAL IN AREAS N
OF INTERSTATE 70. ALTHOUGH SNOW AMOUNTS WILL BE ON THE LOW SIDE OF
SNOW ADVISORY...STG 700 MB WINDS OF 30-40 KTS WILL JUSTIFY THE
ISSUANCE OF A SNOW AND BLOWING SNOW ADVISORY FOR ZONES 31...33 AND
34 FOR SUNDAY.  GOOD SUBSIDENCE COUPLED WITH MID LVL CAA WL ALSO
MAKE FOR THE POSSIBILITY OF STG BORA WINDS ALONG THE FRONT RANGE
FOOTHILLS.  IT IS AGAIN MARGINAL BUT WL GO AHEAD AND ISSUE A HIGH
WIND WATCH FOR THE FRONT RANGE FOOTHILLS FOR SUNDAY AS WELL.  MID
LEVEL INSTBY SHUD BE SUFFICIENT ENUF TO ALLOW SOME HIGHER VELOCITY
WINDS TO MIX DOWN THE THE SFC.  SANGSTER OUTPUT FM BOTH THE ETA AND
GFS INDICATE WATCH/WARNING CRITERIA FM 12Z-18Z SUNDAY.  THE BEST
POTENTIAL FOR STG WINDS AGAIN APPEARS TO BE NORTH OF INTERSTATE 70.
AS FOR THE NERN PLAINS...SELY WINDS SFC WINDS AHEAD OF THE NEXT
SYSTEM WL MAKE FOR MORE STRATUS/FOG CONDITIONS TNGT.  WL LET THE
SWING SHIFT DECIDE ON WHETHER ANOTHER DENSE FOG ADVSY WL BE NEEDED.
IN THE 15-18Z TIME FRAME SUNDAY HOWEVER...THIS LOW LEVEL MSTR POOL
WL GET FLUSHED QUICKLY EASTWARD AS STG WLY WINDS ARE PROGGED TO
DEVELOP WITH THE PASSAGE OF THE SHORT WAVE.  FOR NOW...WILL MENTION
STG GUSTS BUT KEEP THINGS UNDER HIGH WIND CRITERIA...AS THE BEST SFC
PRESSURE GRADIENT IS PROGGED TO BE NORTH OF THE CWFA.

.LONG TERM DISCUSSION...UPPER LEVEL TROF WILL RAPIDLY LIFT OUT INTO
THE NRN HIGH PLAINS SUNDAY EVENING WITH WINDS DECREASING AND SNOW
ENDING IN THE MTNS DURING THE EVENING HOURS. MSTR LEVELS IN THE MTNS
GETS RATHER SHALLOW BUT STEEP ENOUGH LAPSE RATES AND ORORGRAPHICS TO
KEEP SCT SHSN IN THE MOUNTAINS. RIDGING ALOFT MOVES OVER THE STATE
ON MONDAY BUT WILL ALREADY START TO SEE AN INCREASE IN MIDDLE AND
HIGH LEVEL CLOUDS BY MONDAY AFTERNOON AS RIDGE AXIS SHIFTS EAST OF
STATION.

THE NEXT UPPER LEVEL TROF APPROACHES THE WEST COAST TUESDAY NIGHT
WITH INCREASING SW FLOW ALOFT ACROSS COLORADO. SHOWER ACTIVITY WILL
REMAIN ISOLATED ON TUESDAY WITH UNFAVORABLE SW FLOW AND ONLY
MARGINAL LAPSE RATES. ACROSS THE PLAINS...TEMPS WILL BE WARMING UP
THRU TUE AS 700MB TEMPS RISE TO AROUND +2C WITH A GENERAL DOWNSLOPE
SRLY FLOW.  AS FOR THE PROGRESSION OF THE NEXT INCOMING
SYSTEM...LATEST MODELS ARE SHOWING THE LOW COMING ACROSS FURTHER
NORTH AND MORE OF AN OPEN WAVE. LATEST GFS HAS THE LOW COMING ACROSS
IN SEVERAL PIECES WITH STILL SOME ENERGY HANGING BACK ACROSS THE
GREAT BASIN ON THURSDAY. SO AS AN UNORGANIZED SYSTEM BEING STRETCHED
OUT...THIS NEXT TROF WILL PROBABLY HAVE A MINIMAL IMPACT ON OUR
WEATHER AS THIS SCENARIO PLAYS OUT PER CURRENT MODEL GUIDANCE. NOT
MUCH OF AN UPSLOPE COMPONENT OVER THE PLAINS EITHER...AND ANY SHOWER
ACTIVIITY WILL BE MORE ISOLATED VARIETY. SNOW IN THE MOUNTAINS MAY
NOT BE ALL THAT MUCH EITHER AS FLOW REMAINS OUT OF THE SW UNTIL
FRIDAY. AT LEAST COOLER STATEWIDE FOR WEDNESDAY AND THRU THE END OF
THE WEEK. WILL MAINTAIN THE ISOLD POPS ON THE PLAINS FOR LATE WED
AND THU WITH NO EVIDDENCE TO RAISE THEM ANY FURTHER.
