AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
354 AM MST WED FEB 1 2012

.SHORT TERM...ONE MORE DRY AND MILD DAY CAN BE EXPECTED BEFORE BIG
CHANGES BEGIN TOMORROW. A WEAK SHORT WAVE HAS PASSED ACROSS THE
FRONT RANGE EARLY THIS MORNING LEAVING MAINLY CLEAR SKIES ACROSS
THE FORECAST AREA. HOWEVER...HIGH CLOUDS IN ADVANCE OF THE NEXT
STORM SYSTEM ARE TIMED TO REACH THE FORECAST AREA BY 18Z-19Z.
THICKEST CLOUD FORMATION SHOULD ONCE AGAIN BE ON THE LEE SIDE OF
THE FRONT RANGE WITH MOUNTAIN WAVE ENHANCEMENT. THAT COULD HOLD
TEMPS BACK A COUPLE DEGREES...BUT READINGS WILL STILL BE ABOVE
NORMAL.

BY TONIGHT...LARGE SCALE Q-G LIFT WILL BEGIN TO INCREASE AHEAD OF
THE DEVELOPING WINTER STORM. THIS WILL BRING A CHANCE OF SNOW TO
THE MOUNTAINS AFTER MIDNIGHT.

.LONG TERM...IT LOOKS LIKE A VERY INTERESTING WEATHER PATTERN
SHAPING UP FOR THE NEXT COUPLE DAYS. THE GENERAL FORECAST IS FOR A
VIGOROUS SHORT WAVE PRESENTLY OVER WESTERN WASHINGTON AND WESTERN
OREGON TO DIG SOUTHEASTWARD AND FORM INTO AN UPPER LOW OVER THE
FOUR CORNERS BY MIDDAY THURSDAY. THEN THE UPPER LOW WILL SLOWLY
MOVE EASTWARD AND EJECT OVER THE CENTRAL PLAINS THROUGH THE
WEEKEND. THE SHORT WAVE CURRENTLY CONTAINS LARGE VALUES OF
ABSOLUTE VORTICITY...A SIGNIFICANT POTENTIAL VORTICITY LOBE AND
STRONG DRYING EVIDENT ON WATER VAPOR IMAGERY. IT ALSO HAS A 100+
KNOT JET DRIVING IT SOUTHWARD. IT CERTAINLY IS A POTENT LOOKING
FEATURE AT THE PRESENT TIME. AS THE TROUGH DIVES OVER THE GREAT
BASIN...EACH OF THE MODELS KEEP THE UPPER LOW CIRCULATION FAIRLY
BROAD. Q-G DIAGNOSTICS PACKAGE SHOWS A LOT OF RISING MOTION OUT
AHEAD OF THE ADVANCING LOW. AT THE SURFACE...A DEVELOPING LOW OVER
NEW MEXICO IS GOING TO BE OPEN ON THE EAST SIDE ALL THE WAY TO THE
GULF OF MEXICO. SIGNIFICANT AMOUNTS OF MOISTURE WILL BE ABLE TO
ADVECT NORTHWARD OVER THE CENTRAL PLAINS AND FEED INTO THE
DEVELOPING STORM. BY THURSDAY NIGHT...MOST OF EASTERN COLORADO
SHOULD BE SEEING PRECIPITATION...POSSIBLY BEGINNING AS RAIN AND
RAPIDLY CHANGING TO SNOW. SNOWFALL WILL THEN INTENSIFY OVERNIGHT
AS THE SURFACE LOW BEGINS TO OCCLUDE AND A BIT OF A TROWAL
DEVELOPS OVER NORTHEAST COLORADO. SURFACE PRESSURE GRADIENTS WILL
BE INCREASING WITH WINDS ON THE PLAINS BECOMING GUSTY. BLOWING
SNOW MAY THEN BECOME A PROBLEM AS THE SYSTEM COOLS AND SNOW
CONTINUES FALLING. EACH OF THE FOUR MODELS HAVE THE HEAVIEST
SNOWFALL IN A DIFFERENT LOCATION...VARYING FROM THE 06Z GFS
BULLSEYE OVER DENVER AND THE I-76 CORRIDOR TO THE ECMWF PLACING
THE HEAVIEST SNOW IN NORTHWEST KANSAS WITH A SECONDARY MAXIMUM
OVER THE PALMER DIVIDE. WITH A HEALTHY DOSE OF UNCERTAINTY...BUT
ALSO A STRONG POSSIBILITY OF HEAVY SNOW OVER NORTHEAST
COLORADO...WILL ISSUE A WINTER STORM WATCH FOR THURSDAY EVENING
THROUGH FRIDAY EVENING. LATER SHIFTS MAY NEED TO EXTEND THE WATCH
INTO THE FOOTHILLS...BUT UNCERTAINTIES IN THE EVENTUAL STORM TRACK
MAKE ME CAUTIOUS FOR NOW. AS THE UPPER TROUGH HAS MOVED ONSHORE
THIS MORNING...THE NEXT FEW MODEL RUNS SHOULD BENEFIT FROM BETTER
SAMPLING...AND HOPEFULLY THE RANGE OF SOLUTIONS WILL BEGIN TO
NARROW.

OVER THE WEEKEND...THE PATTERN BECOMES EVEN MORE INTERESTING AS
THE UPPER LOW GETS CUT OFF FROM THE NORTHERN JET STREAM AND A REX
BLOCK DEVELOPS OVER THE WESTERN 2/3 OF THE COUNTRY. THE LEADING
UPPER LOW MAY STALL OVER THE CENTRAL PLAINS AS A SECONDARY
CIRCULATION ROTATES DOWN INTO THE GREAT BASIN. NORTHEAST COLORADO
WILL REMAIN UNDER THE NORTHWEST QUADRANT OF THE GREAT PLAINS UPPER
LOW...BUT MAY ALSO SEE SOME EFFECTS FROM THE WEAKER WESTERN UPPER
LOW. THIS WOULD KEEP UNSETTLED WEATHER IN THE MOUNTAINS THROUGH
THE WEEKEND.

FOR THE FIRST PART OF NEXT WEEK...THE REX BLOCK WILL EVENTUALLY
BREAK DOWN...BUT MODELS WILL STRUGGLE WITH FORECASTING THE DEMISE
OF THE BLOCK. THE ECMWF SHOWS A RIDGE OVER NEVADA AND IDAHO WITH
COLORADO UNDER DRIER NORTHWESTERLY FLOW. THIS WOULD KEEP COOLER
TEMPERATURES IN PLACE THROUGH THE MIDDLE OF NEXT WEEK.

&&

.AVIATION...SOUTHWESTERLY WINDS MAY BRIEFLY SHIFT TO WEST/
NORTHWEST AT KDEN AND KAPA THIS MORNING AS DOWNSLOPE TRIES TO
WORK OFF THE FRONT RANGE. KBJC SHOULD SEE A FEW WEST/NORTHWEST
GUSTS AROUND 25 KTS. OTHERWISE EXPECT A SIMILAR WIND REGIME TO
YESTERDAY WITH ANTICYLONIC FLOW RESULTING IN SOUTHEASTERLY WINDS
BY 18Z-19Z. WINDS WILL THEN TRANSITION TO DRAINAGE SOUTH/SOUTHWEST
BY 02Z-05Z.

COLD FRONTAL PASSAGE IS EXPECTED AROUND MID MORNING THURSDAY...
WITH SNOW SHOWERS AND MVFR CONDITIONS DEVELOPING IN THE AREA
