AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
355 AM MST WED FEB 14 2007

.SHORT TERM...LIGHT SNOW CONTINUES ACROSS MOST OF THE AREA. WEAK
UPWARD FORCING ALOFT SHIFTING ONTO THE PLAINS WITH SOME DECREASE
OVER THE WESTERN HALF OF THE AREA...BUT MOIST BOUNDARY LAYER...
COOLING...AND WEAK UPSLOPE WILL LIKELY KEEP VERY LIGHT SNOW GOING IN
MANY AREAS DURING THE DAY. NORTHERN STREAM TROUGH RACES SOUTH OUT OF
MONTANA...NOT TOO SURE ABOUT THE FASTER TIMING THE MODELS HAVE WHICH
WOULD SUGGEST ENHANCED UPSLOPE WINDS AND UPWARD FORCING RETURNING BY
THE END OF THE DAY...BUT THIS IS JUST THE DIFFERENCE BETWEEN
FLURRIES AND LIGHT SNOW ANYWAY. MODELS SUGGEST A BIT STRONGER LIFT
WITH THIS BUT ONLY FOR A FEW HOURS. MODEL QPF/SNOW GRIDS INDICATE
1-2 INCHES IN GENERAL...WITH UP TO 4 INCHES ALONG THE FOOTHILLS FROM
MODEST UPSLOPE THIS EVENING...SEEMS REASONABLE. TROUGH AXIS IS PAST
BY MORNING WITH WINDS STARTING IN THE HIGHER MOUNTAINS AND DRYING
ALOFT...STARTING TO PUSH OUT THE BOUNDARY LAYER MOISTURE LATE
TONIGHT. COOLED HIGH TEMPERATURES TODAY A COUPLE OF DEGREES WITH
CLOUDY SKIES AND LIGHT PRECIP...WELL BELOW GUIDANCE. CURRENT
FORECAST LOWS NEAR NAM GUIDANCE LOOK GOOD AS MOISTURE SHOULD HOLD UP
THE TEMPS.

.LONG TERM...MODELS HAVE NORTHERLY FLOW ALOFT ON THE INCREASE FOR
THE FORECAST AREA THURSDAY AND THURSDAY NIGHT.  BY FRIDAY AND FRIDAY
NIGHT A PIECE OF ENERGY USHERS IN A NORTHWESTERLY JET MAX FOR
FORECAST AREA.  THE QG VERTICAL VELOCITY FIELDS HAVE DOWNWARD MOTION
PROGGED FOR THE FORECAST AREA THURSDAY AND THURSDAY NIGHT.  THERE IS
A BRIEF SHOT OF UPWARD MOTION FOR SOME OF THE FORECAST AREA ON
FRIDAY...BUT ITS ALL DOWNWARD MOTION AGAIN BY LATER IN THE
AFTERNOON WELL INTO SATURDAY.  THE LOW LEVEL WIND AND PRESSURE
FIELDS INDICATING LINGERING UPSLOPE FOR SOME OF THE PLAINS EARLY
THURSDAY.  BY THURSDAY EVENING AND OVERNIGHT...LOW LEVEL TROUGHING
DEVELOPS EAST OF THE MOUNTAINS.  THIS MOVES EAST BY FRIDAY AFTERNOON
WITH DECREASE NORTHWESTERLY DOWNSLOPING PROGGED FRIDAY AFTERNOON
WELL INTO SATURDAY.   FOR MOISTURE...THE MOUNTAINS STAY PLENTY WET
THURSDAY AND THURSDAY NIGHT.  THERE IS STILL PRETTY GOOD MOISTURE
THERE ON BOTH MODELS FRIDAY AND FRIDAY NIGHT...THE GFS WITH MORE.
OVER THE PLAINS...THE LOW LEVEL MOISTURE DOES LINGER EARLY ON
THURSDAY...THE MID AND UPPER LEVELS DRY SIGNIFICANTLY.  HOWEVER...
BY AFTERNOON INTO THURSDAY EVENING A DECENT BATCH OF DEEP MOISTURE
MOVES BACK IN.  THIS DECREASES AGAIN BY LATE EVENING AND OVERNIGHT.
FRIDAYS PRETTY DRY...JUST SOME UPPER LEVEL CLOUDINESS BY
AFTERNOON.  SOME MID AND UPPER LEVEL MOISTURE IS PROGGED OVERNIGHT
FRIDAY INTO SATURDAY.  FOR MOUNTAIN POPS...OROGRAPHIC ENHANCEMENT
LOOKS GOOD IN OUR MOUNTAINS...SO DOES THE MOISTURE.  THERE IS SOME
WARMING HOWEVER.  LIKELY POPS ARE OK THURSDAY AND THURSDAY
NIGHT...BUT EXPECTED AMOUNTS DO NOT WARRANT HIGHLIGHTS AT THIS TIME.
WITH LESS MOISTURE...WILL GO SCATTEREDS IN THE MOUNTAINS FRIDAY
INTO SATURDAY.  OVER THE PLAINS...MAY NEED SOME SLIGHT POPS EARLY
THURSDAY WITH LINGERING IN MIND.  LATER IN THE DAY/EVENING...MAY
NEED SOME LIMITED POPS OVER THE FOOTHILLS AND IMMEDIATE PLAINS WITH
MOISTURE AND NORTH-NORTHWESTERLY FLOW IN MIND.  WILL PULL THE POPS
OVER THE PLAINS FRIDAY WITH BOTH MODELS SHOWING POOR MOISTURE
AVAILABILITY.   CONCERNING WIND...CROSS SECTIONS SHOW A DECENT
MOUNTAIN TOP STABLE LAYER IN PLACE THURSDAY NIGHT AND EARLY FRIDAY
THEN AGAIN SATURDAY MORNING. WINDS WILL DEFINITELY PICK UP...NEED TO
WATCH THIS.  FOR TEMPERATURES...THICKNESS GRIDS PUT THURSDAYS
HIGHS 2-4 C WARMER THAN TODAYS.  FRIDAY IS 1-3 C HIGHER...EXCEPT
HIGHER OVER THE FAR NORTHEAST CORNER.   NO CHANGE FOR THE LATER
DAYS.
