AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
345 PM MDT THU APR 2 2009

.SHORT TERM...A RATHER COMPLICATED SITUATION...AT LEAST FOR THE HIGH
COUNTRY.  FIRST FOR THE PLAINS...LEE TROUGHING SHOULD BE SUFFICIENT
TO KEEP THE MOST OF THE PRECIPITATION THREAT AT BAY THROUGH 04/00Z
ASIDE FROM AN ISOLATED SHOWER/THUNDERSTORM DURING THE AFTERNOON.
REGARDING THE HIGH COUNTRY NOT MUCH IS GOING ON UP THERE AT THIS
POINT IN TIME ASIDE FROM SOME SNOW SHOWERS OVER THE HIGHER LOCALES.
THE MODELS SHOW A BATCH OF WEAKENING QG LIFT COMING OVER THAT AREA
DURING THE EVENING WHICH SWITCHES TO SUBSIDENCE BY 12Z FRIDAY.  THE
QPF FROM THE MODELS OVERNIGHT IS ALSO QUITE EXCITED BUT WEB CAMS AND
SURFACE REPORTS FROM UPSTREAM ARE NOT ALL THAT IMPRESSIVE.  UPSTREAM
RADARS HAVE BEEN FILLING IN HOWEVER.  HAVE OPTED TO CUT BACK ON
MODEL QPF AMOUNTS BUT HAVE KEPT THE THREAT OF PRECIPITATION GOING UP
THERE...INCREASING THROUGH THE EVENING THEN SETTLING DOWN AFTER
DAYBREAK AS THE SUBSIDENCE KICKS IN.  OROGRAPHICS ARE CERTAINLY NOT
IDEAL...BEING BEST IN THE PARK/GORE RANGE...BUT DYNAMICS AND LIKELY
SOME CONVECTION WILL BE ABLE TO PRODUCE SOME SNOW.  AFTER A SLIGHT
BREAK UP THERE IN THE MORNING QG LIFT WITH THE NEXT SYSTEM STARTS
SPREADING INTO THE HIGH COUNTRY DURING THE AFTERNOON SO HAVE
INCREASED POPS AGAIN IN RESPONSE TO THAT.  WOULD NOT BE SURPRISED TO
SEE SOME THUNDER UP THERE TOMORROW AFTERNOON EITHER.

.LONG TERM...WINTER STORM IS ON TRACK...BUT THERE ARE MANY DETAILS
WHICH MAKE THIS A DIFFICULT FORECAST.  UPPER LEVEL TROUGH WILL DIG
SOUTHEAST ACROSS UTAH FRIDAY NIGHT AND APPROACH THE FOUR CORNERS
REGION BY 12Z SATURDAY.  THIS OCCURS AS THE NEXT PIECE OF ENERGY NOW
SEEN JUST OFF THE BRITISH COLUMBIA COAST DROPS INTO THE BACK SIDE OF
THIS TROUGH.  AT THIS RATE...WITH THIS AMOUNT OF JET ENERGY WE
SHOULD BE ABLE TO CLOSE OFF THE UPPER LEVEL LOW NEAR THE 4
CORNERS...BUT WHAT IS A LITTLE CONCERNING IS THE PERSISTENCE OF THE
ECMWF TO CLOSE THE SYSTEM OFF CLOSER TO GRAND JUNCTION AND THEN
TRACK THE LOW FARTHER NORTH...PASSING JUST SOUTH OF DENVER BY MID
DAY SATURDAY.  IF THAT VERIFIES...THEN WE COULD BE LOOKING AT LESS
SNOWFALL.

THE OTHER AREA OF CONCERN IS HOW MUCH SNOW OCCURS FRIDAY EVENING.
THINGS ARE QUITE WARM TO START OFF WITH BUT RAPID COOLING IS
EXPECTED DURING THE COURSE OF THE EVENING AS WE GET PRECIPITATION
GOING AND A COLD FRONTAL PASSAGE WITH PUSH OF DEEPER COLD AIR FROM
THE NORTHEAST.  THE RESULTANT UPSLOPE DEEPENS TO ABOUT 11 THOUSAND
FEET AND STRENGTHENS TO 20-25 KNOTS PER THE NAM AND GFS.  THIS PUSH
SEEMS TO BE HIGHLY DEPENDENT ON THE LEAD SHORT WAVE AND ASSOCIATED
SUBSIDENCE BEHIND IT WHICH MOVES ACROSS WYOMING TOMORROW.  IF THIS
COMES TO FRUITION...THEN WE WOULD BE LOOKING AT RAIN SHOWERS QUICKLY
CHANGING OVER TO HEAVY SNOW ALONG THE FRONT RANGE AS EARLY AS
TOMORROW EVENING.  THE ATMOSPHERE IS QUITE MOIST AND UNSTABLE WITH
PRECIPITABLE WATER VALUES AROUND 0.40 TO 0.45 INCH AND NEARLY MOIST
ADIABATIC LAPSE RATES...SO SNOWFALL RATES COULD BE 1-2 INCHES PER
HOUR IF THIS ALL COMES TOGETHER.   MEANWHILE...THE ECMWF DOES NOT
BRING THAT SURGE IN VERY DEEP AT ALL...RESULTING IN ANY
PRECIPITATION TOMORROW EVENING MOSTLY CONFINED TO THE WYOMING BORDER
AREA.  THEREFORE... THERE ARE SMALL DIFFERENCES WHERE JUST A 100
MILES OR SO OF STORM TRACK AS WELL AS LOCATION AND DEPTH OF COLD
FRONT WILL PLAY A LARGE ROLE WITH REGARD TO STORM TOTAL
ACCUMULATION.  AT THIS TIME...THE WINTER STORM WATCH WITH POSSIBLE
SNOW AMOUNTS OF 5 TO 12 INCHES OF SNOW ACROSS THE PLAINS AND 8 TO 15
INCHES IN THE MOUNTAINS DURING THE FRIDAY NIGHT/SATURDAY PERIOD
LOOKS ON TRACK.  IF HEAVY SNOW OCCURS FRIDAY NIGHT ALREADY THEN
THESE AMOUNTS WOULD BE UNDERDONE ACROSS THE METRO AREAS AND FRONT
RANGE FOOTHILLS.  HOWEVER...IF THE ECMWF VERIFIES THEN THESE AMOUNTS
WOULD BE OVERDONE...SO WILL LEAVE THE WATCH AND POSSIBLE SNOW
ACCUMULATION NUMBERS ALONE FOR NOW.  WINDS ARE STILL EXPECTED TO
INCREASE CONSIDERABLY BY SATURDAY AS THE SURFACE LOW INTENSIFIES
OVER THE HIGH PLAINS WITH POSSIBLE BLIZZARD CONDITIONS DEVELOPING.

CANT RULE OUT A SNOW SHOWER LINGERING SUNDAY BEHIND THE STORM SINCE
ANOTHER WEAK DISTURBANCE IS SEEN DROPPING DOWN THE BACK SIDE OF THE
TROUGH AS IT KICKS INTO THE MIDWEST.  OTHERWISE LOOK FOR A WARMUP
UNTIL THE NEXT SYSTEM ARRIVES BY THE MID TO LATE PART OF NEXT WEEK.
THIS ONE IS LOOKING WARMER AND WEAKER THAN THIS WEEKENDS STORM.

&&

.AVIATION...VFR CONDITIONS TONIGHT AND FRIDAY.  THERE MAY BE SOME
CONVECTIVE ACTIVITY AROUND FRIDAY AFTER 20Z OR SO BUT THE BRUNT OF
THE WEATHER WILL HOLD OFF UNTIL AFTER 00Z.

&&

.BOU WATCHES/WARNINGS/ADVISORIES...WINTER STORM WATCH FOR THE NORTH
   CENTRAL MOUNTAINS...FRONT RANGE FOOTHILLS...AND PARK COUNTY FOR
   FRIDAY NIGHT AND SATURDAY..ZONES 31..33>37.
 WINTER STORM WATCH FOR THE URBAN CORRIDOR AND ADJACENT PLAINS FOR
