.SHORT TERM...A STG UPPER LEVEL STORM SYSTEM WILL APPROACH THE AREA
FROM THE WEST.  AHEAD OF THIS SYSTEM THERE WILL BE INCREASING SSW
FLOW ALOFT.  SATELLITE SHOWS A DRY SLOT MOVING INTO WRN CO WHICH
WILL LIKELY BE OVER MUCH OF THE AREA THRU THE AFTN HOURS SO WILL
ONLY MENTION SOME ISOLD CONVECTION IN THE MTNS FOR LATE THIS AFTN.
OVER THE PLAINS LOW LEVEL MOISTURE WILL GRADUALLY MIX OUT EXCEPT
OVER THE FAR NERN CORNER WHERE AN ISOLD TSTM OR TWO COULD DVLP BY
LATE AFTN MAINLY OVER LOGAN...PHILLIPS AND SEDGWICK WHERE CAPES WILL
BE IN THE 500-1000 J/KG.  TEMPS TODAY SHOULD BE JUST AS WRM AS
YESTERDAY AND COULD EVEN BE A FEW DEGREES WARMER WITH MORE OF A
DOWNSLOPE COMPONENT IN PLACE.  FIRE DANGER WILL BE HIGH IN THE
FOOTHILLS AND OVER PARK COUNTY AND THE PALMER DIVIDE.  HAVE ADDED
ZONE 35 TO RED FLAG WARNING.

FOR TONIGHT THE ENSEMBLE DATA SHOWS MAIN UPPER LEVEL LOW MOVING INTO
NWRN CO BY 06Z AND THEN TO NR DENVER BY 12Z MON.  WITH FAVORABLE QG
ASCENT AND DECENT LAPSE RATES SNOW SHOULD INCREASE IN THE MTNS AFTER
MIDNIGHT.  OVER NERN CO INTENSE SFC LOW WILL DVLP OVER NERN CO WITH
GUSTY DOWNSLOPE NWLY WINDS DEVELOPING IN AND NR THE FOOTHILLS.
THERE COULD BE A FEW TSTMS DURING THE EVENING HOURS NR THE DRYLINE
EAST OF A STERLING TO AKRON LINE WITH A FEW POSSIBLE SVR DUE TO
FAVORABLE SHEAR.  MEANWHILE DESPITE DOWNSLOPE FLOW ALONG THE FRONT
RANGE STG QG ASCENT WILL AFFECT THE AREA TOWARDS 12Z AND WITH STEEP
LAPSE RATES COULD SEE SOME RAIN/SNOW SHOWERS DVLP ESPECIALLY ALONG
THE CO-WY BORDER AREA.

.LONG TERM...MODELS HAVE THE UPPER LOW CENTERED RIGHT AROUND THE
URBAN CORRIDOR AT 12Z MONDAY MORNING...THEN IT'S RIGHT OVER THE
NORTHEASTERN TIP OF THE STATE AT 18Z MONDAY.  BY MONDAY NIGHT...WEAK
NORTHWESTERLY FLOW IS PROGGED OVER THE FORECAST AREA...WITH WEAK
ZONAL FLOW ON TUESDAY.  BY TUESDAY NIGHT THE GFS PUSHES A WEAK
TROUGH OVER US...THE NAM IS A BIT SLOWER WITH THIS FEATURE.  THE
STRONG SYNOPTIC SCALE UPWARD MOTION IS OVER THE NORTHERN HALF OF THE
FORECAST AREA UNTIL ABOUT MID AFTERNOON MONDAY.  WEAKER UPWARD
MOTION LINGERS OVER THE FAR NORTHERN PLAINS UNTIL ABOUT MID MONDAY
EVENING.  DOWNWARD MOTION IT OVER THE FORECAST AREA THROUGH LATE
TUESDAY.  THERE IS WEAK UPWARD MOTION PROGGED TUESDAY NIGHT.
MODELS STILL HAVE THE SURFACE CYCLONE OVER THE CORNER OF
NORTHEASTERN COLORADO MONDAY MORNING AT 12Z.  NORTHWESTERLY FLOW IS
PROGGED IN THE BOUNDARY LAYER MONDAY WELL INTO TUESDAY AFTERNOON.
AGAIN...A PRETTY TIGHT GRADIENT IS PROGGED MONDAY AND MONDAY
NIGHT...WITH THE STRONGEST WINDS EXPECTED OVER THE NORTHEASTERN
CORNER ZONES.  THE NAM INDICATED WEAK UPSLOPE FOR THE PLAINS LATE
TUESDAY AND MUCH OF TUESDAY NIGHT...THE GFS HAS NORMAL DIURNAL WIND
TRENDS TO PREVAIL DURING THAT TIME.  MODELS HAVE DEEP MOISTURE OVER
THE MOUNTAINS MONDAY INTO TUESDAY MORNING.  IT DECREASES SOMEWHAT BY
TUESDAY AFTERNOON...BUT THERE IS STILL PLENTY WELL INTO WEDNESDAY.
OVER THE EASTERN PLAINS...THERE IS DEEP MOISTURE AS WELL MONDAY AND
MONDAY NIGHT.  TUESDAY DRIES OUT IN THE LOWER LEVELS.  FOR THE
WESTERN PLAINS...THERE IS PLENTY OF MID AND UPPER LEVEL
MOISTURE...WITH SOME DRYING IN THE LOWER LEVELS FROM THE
DOWNSLOPING.  TUESDAY IS PRETTY DRY.  THE NAM INCREASES PLAIN'S
MOISTURE LATE TUESDAY CONTINUING TUESDAY NIGHT WITH THE UPSLOPE IT
SHOWS.  OVERALL WITH THE SYSTEM...THE GFS HAS DEEPER MOISTURE THAT
STAYS AROUND LONGER.  THE QPF FIELDS SHOW MEASURABLE PRECIPITATION
MONDAY AND MONDAY NIGHT...THE BEST IS IN THE MOUNTAINS AND NORTHERN
FORECAST AREA.  THE MOUNTAINS HAVE MEASURABLE TUESDAY AND TUESDAY
NIGHT AS WELL.  FOR THE MOUNTAINS...A WARNING LOOKS GOOD AND THE
SNOW MODEL AGREES.  THE WARNING NEEDS TO GO THROUGH 12Z TUESDAY
MORNING.  WILL KEEP DECENT POPS GOING TUESDAY AND TUESDAY NIGHT AS
WELL.  FOR THE PLAINS...IT STILL LOOKS LIKE THE BEST CHANCES OF SNOW
WILL BE OVER THE NORTHEAST CORNER.  TO MUCH DOWNSLOPING FOR THE
FOOTHILLS AND PLAINS FOR A DECENT PRECIPITATION EVENT THERE.
TEMPERATURES ARE 11 TO 21 C COLDER ON MONDAY COMPARED TO TODAY'S.
TUESDAY'S HIGHS ARE CLOSE TO MONDAY'S.  FOR THE LATER DAYS...
WEDNESDAY THROUGH SATURDAY...INCREASING ZONAL FLOW ALOFT IS PROGGED
ON WEDNESDAY.  BY THURSDAY INTO FRIDAY MODELS STILL HAVE AN UPPER
TROUGH/CLOSED LOW MOVE ACROSS.  THE GFS HAS IT IN THE BEST SPOT FOR
DECENT SNOW OVER OUR FORECAST AREA.  THE ECMWF HAS A BIT FURTHER
SOUTH...AND THE DGEX HAS IT FURTHER SOUTH STILL.  THERE DOES LOOK TO
BE UPSLOPE AND A COLDER AIR MASS WITH THE SYSTEM...EVEN IF IT IS
JUST AN OPEN TROUGH.  AT LEAST THE PATTERN FOR THE NEXT WEEK ISN'T
DOMINATED BY THE USUAL UPPER RIDGE.
