AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
340 PM MDT WED MAR 25 2009

.SHORT TERM...THIS SNOW FORECAST IS NOT QUITE A SLAM DUNK...BUT
PRETTY CLOSE. FCST TEAM HERE AT THE OFFICE TRIED TO FIND REASONS WHY
WE WOULDN/T SEE SIGNIFICANT SNOWFALL ACROSS THE CWFA NEXT 24 HOURS.
COULD COME UP WITH ONLY A FEW POSSIBILITIES SUCH AS IF THE 700-500
LOW TRACKS FARTHER SOUTH UPSLOPE WOULD BE WEAKER/NOT AS DEEP...SO
SNOW AMTS COULD BE MUCH LESS. HOWEVER THE LATEST MODEL RUNS ACTUALLY
SHOW THE UPPER TAKING A MORE NORTHERLY TRACK ALONG THE COLORADO/NEW
MEXICO BORDER. THEN THERE/S THE TEMPERATURE ON THURSDAY...WHICH THE
18Z/NAM SHOWS 850 TEMPS ON THE PLAINS REMAINING ABOVE FREEZING UNTIL
MIDDAY THURSDAY. BUT THAT FLIES IN THE FACE OF THE NAM WIND AND PRES
FIELDS WHICH INDICATE THE ARRIVAL OF A STRONG FRONTAL SURGE IN THE
DENVER AREA AROUND MID-MORNING. NAM ALSO INDICATES STG 850-500MB QG
ASCENT OVER NERN COLORADO MID-MORNING TO MID-AFTERNOON AS THE 700 MB
LOW PRES CENTER PASSES OVER SERN COLORADO. THE OTHER FCST MODELS AT
OUR DISPOSAL SHOW SIMILAR FEATURES WITH THE BEST SYNOPTIC SCALE AND
OROGRAPHIC LIFT WEST OF THE CONTINENTAL DIVIDE TONIGHT AND EAST OF
THE DIVIDE DURING THE DAY THURSDAY. CONSEQUENTLY HAVE ALREADY
UPGRADED THE WINTER STORM WATCH TO A WARNING FOR ALL BUT NORTH AND
MIDDLE PARK ZONES FOR LATE TONIGHT THROUGH 12Z/FRIDAY. WILL GO AHEAD
AND ISSUE A WINTER WEATHER ADVISORY FOR THESE TWO ZONES SHORTLY.
PAST FEW DAYS BIGGEST QUESTION HAS BEEN WHEN WILL ACCUMULATING
SNOWFALL BEGIN AND END.  IT WAS REALLY NEVER IN DOUBT WHEN THE
HEAVIEST SNOWFALL AND STRONGEST WINDS WOULD OCCUR. ON THE PLAINS IT
STILL LOOKS LIKE FROM 18Z/THU TO 06Z/FRI. MODEL WIND FIELDS INDICATE
N-NELY WINDS OF 20-30KTS WITH HIGHER GUSTS TO AROUND 40KT
POTENTIALLY CREATING NEAR BLIZZARD CNDTNS IN THE AREA IMMEDIATELY
EAST OF I-25 AND OVER THE PALMER DIVIDE S-SE OF DENVER IN THE
AFTERNOON. WILL REFRAIN FROM TRYING TO LIST ALL THE SNOW AMOUNTS
EXPECTED BY 00Z/FRI. WILL LEAVE THAT TO THE FORECAST AND WINTER
STATE WARNING STATEMENT.

.LONG TERM...MAIN CONCERN WILL BE THE CONTINUED FOR HEAVY SNOWFALL
THRU THURSDAY NIGHT AND ANY LINGERING EFFECTS THROUGH FRIDAY. MODELS
ARE VERY SIMILAR THRU 06Z THURSDAY WITH THE UPPER LOW ACROSS NW NEW
MEXICO. MODELS DIVERGE THEREAFTER WITH THE GFS FURTHEST SOUTH AND
MOST PROGRESSIVE WHILE THE NAM IS SLOWER AND A BIT FURTHER NORTH.
REGARDLESS OF THE STORM TRACKS...THE MODELS ARE SHOWING WIDESPREAD
HEAVY SNOW OVER MUCH OF THE CWA FOR THU AFTN THROUGH AT LEAST
MIDNIGHT. EVERYTHING CONTINUES TO POINT TO A MAJOR SNOW PRODUCER
WITH STRONG N-NE FLOW THROUGH ABOUT 550MB AND 700MB WINDS OF 25-35KT
AND STEEP LOW LVL LAPSE RATES. VERTICAL VELOCITY FIELDS SHOW STRONG
UPWARD FORCING AT ALL LVLS WITH A GRADUAL DECREASING TREND TOWARDS
FRI AM AS THE LOW PULLS A BIT FURTHER AWAY. LOCAL SNOW MODEL YIELDS
UPWARDS OF 2 FT OF SNOW OVER THE FOOTHILLS...GIVEN THE HIGHER
DENSITY SNOW WITH THE FORCING. THIS MATCHES FAIRLY GOOD WITH THE
HIGHER OUTPUT OF THE NAM. EVEN THE FURTHER SOUTH TRACK OF THE GFS
STILL GIVES 15 INCHES OF SNOW OVER  A GOOD CHUCK OF THE PLAINS. WILL
BOOST SNOW AMOUNTS UPWARDS FROM PREVIOUS PACKAGE...BUT WILL STAY ON
THE CONSERVATIVE SIDE FOR THE TIME...ESP BELOW THE HIGHER NAM
AMOUNTS OF OVER 30 INCHES OVER THE FOOTHILLS. NOT TO SAY IT WONT
HAPPEN...BUT WOULD BE ON THE LOWER PROBABILITIES OF OCCURRENCE.
SNOWFALL RATES COULD APPROACH 2 INCHES/HR WITH THE HEAVIER SNOW THU
AFTN/EVENING. THE STRONG NORTHERLY WINDS OF 20-35KT WILL ALSO CREATE
BLOWING AND DRIFTING SNOW THUR NITE. THE SNOW AMOUNTS OVER THE FAR
NERN PLAINS MAY BE MARGINAL FOR HEAVY SNOW BUT GIVEN THE STRONG
WINDS...EXPECT PROBLEMS THERE AS WELL.

GIVEN THE TIMING DIFFERENCES AT THE BACK END OF THE STORM WONT MAKE
ANY CHANGES TO THE ENDING PERIOD OF THE HILITES DUE TO HIGHER
UNCERTAINTY IN THOSE PERIODS. IF STORM IS A BIT SLOWER LIKE THE
NAM...HILITES MAY NEED TO BE EXTENDED OVER THE PALMER DIVIDE REGION.

BEYOND OUR BREWING STORM FOR THURSDAY...LONG RANGE MODELS SHOW
ANOTHER STORM FOR LATE SUNDAY...BUT APPEARS THIS STORM WILL COME
ACROSS AS AN OPEN WAVE. INTRODUCED ISOLATED POPS OVER THE PLAINS FOR
SUNDAY NIGHT. THE GFS OFFERS UP AN EVEN STRONGER STORM FOR NEXT
WEDNESDAY TIME FRAME...HOWEVER THE EUROPEAN HAS A FAST...ZONAL FLOW
FOR THE SAME TIME PERIOD. ADDED A SLIGHT CHC OVER THE PLAINS FOR
GOOD MEASURE.

&&

.AVIATION...VFR CONDITIONS WITH ISOLATED LIGHT RAIN AND SNOW SHOWERS
IN THE DENVER AREA THROUGH MIDNIGHT...THEN WATCH FOR LOWERING
CEILINGS WITH SCATTERED SNOW SHOWERS DEVELOPING AFTER MIDNIGHT. ON
