AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
241 PM MDT TUE APR 29 2008

SHORT TERM...WE HAVE YET TO SEE RED FLAG CONDITIONS ON THE PLAINS
THIS AFTERNOON...AS OF 2PM HUMIDITIES HAVE DROPPED TO 10 PERCENT AT
SEVERAL STATIONS...BUT WINDS HAVE ONLY GUSTED INTO THE HIGH TEENS.
WITH MAX HEATING STILL A COUPLE OF HOURS AWAY...WILL LIKELY SEE WIND
GUSTS REACH THE MID 20S BRIEFLY...SO WILL LEAVE RED FLAG WARNING IN
THE FORECAST UNTIL 8PM.

DRY AND STABLE AIR TONIGHT...BUT THE TROUGH APPROACHES.  BY 12Z IT
WILL BE OVER IDAHO.  WEDNESDAY THE TROUGH WILL DIG SLIGHTLY TO UTAH
AND WESTERN WYOMING AND THERE WILL BE WEAK UPWARD FORCING THROUGH
THE DAY...INCREASING ALONG THE WYOMING BORDER LATER IN THE
AFTERNOON.  WILL LEAVE THE 10 PERCENT POPS ACROSS THE NORTHERN
COUNTIES...A FEW TSTMS WILL BE POSSIBLE IN THE LATE AFTERNOON
HOURS...AND IT AGREES WITH SPC AND CHEYENNE.

A LEE TROUGH WILL INTENSIFY IN EASTERN COLORADO WEDNESDAY...WITH
WINDS SWITCHING FROM SOUTHWESTERLY TO WESTERLY THEN NORTHERLY BY
EARLY EVENING AS COLDER AIR SURGES IN FROM WYOMING.  IN THE
PREFRONTAL PERIOD IN THE EARLY AFTERNOON WE WILL BE WATCHING FOR
ANOTHER BOUT OF POSSIBLE RED FLAG CONDITIONS.  AGAIN HUMIDITIES WILL
BOTTOM BELOW 10 PERCENT...BUT WINDS MAY FALL SHORT...AND WHEN COLDER
AIR SURGES IN LATER IN THE AFTERNOON THE HUMIDITIES WILL BE
RECOVING.  FOR NOW A RED FLAG WATCH DOES NOT LOOK NECESSARY SO WILL
LET NEXT SHIFTS GET A LOOK AT NEW DATA.

LONG TERM...MODELS HAVE INCREASING SOUTHWESTERLY FLOW ALOFT
WEDNESDAY EVENING...THEN THE UPPER TROUGH AXIS MOVES ACROSS THROUGH
EARLY THURSDAY AFTERNOON.  AT 18Z THURSDAY...MODELS SHOW THE UPPER
LEVEL CIRCULATION FROM SOUTH CENTRAL WYOMING INTO NORTHWESTERN
NEBRASKA.  THE ECMWF ALSO HAS THE CLOSED FEATURE A BIT NORTH FROM
PREVIOUS RUNS.  IT HAS THE CLOSED LOW MORE OVER WEST CENTRAL
NEBRASKA AT 18Z THURSDAY.  SO THEY ARE ALL FAIRLY CLOSE ON THE
LOCATION.  THE QG VERTICAL VELOCITY FIELDS HAVE UPWARD MOTION FOR
THE FORECAST AREA WEDNESDAY NIGHT THROUGH NOON THURSDAY.  THE
BEST/STRONGEST UPWARD MOTION IS TO OUR NORTH.  BY 18Z THURSDAY AND
ONWARD...DECENT DOWNWARD MOTION IS PROGGED...CONTINUING THROUGH
FRIDAY EVENING.  MODELS NOW SHOW THE SURFACE CYCLONE OVER EAST
CENTRAL COLORADO/WEST CENTRAL KANSAS WEDNESDAY EVENING.  THE
BOUNDARY LAYER FLOW IS NORTHERLY WEDNESDAY EVENING UNTIL ABOUT
06Z/09Z...THEN ITS ALL NORTHWESTERLY FOR THE PLAINS AND FOOTHILLS
THE REST OF THE NIGHT...THURSDAY...THURSDAY NIGHT...AND FRIDAY.
FOR MOISTURE...WEDNESDAY EVENING STARTS OUT FAIRLY DRY.  THE
MOISTURE INCREASES BY LATE EVENING.  THE MOISTURE IS BEST AROUND 09Z
...DEEPEST OVER THE MOUNTAINS.  BY MID THURSDAY MORNING...THE PLAINS
ARE DRYING OUT IN THE LOWER LEVELS WITH SOME MOISTURE IN THE MID AND
UPPER LEVELS THROUGH THE REST OF THE DAY.  THE MOUNTAINS ARE MORE
MOIST THROUGH THE DAY THURSDAY BUT ITS NOT VERY DEEP.  FOR THURSDAY
NIGHT INTO FRIDAY MORNING THE EASTERN BORDER AREA HAS SOME WRAP
AROUND MOISTURE...THE REST OF THE PLAINS ARE QUITE DRY IN THE LOWER
AND MID LEVELS.  MOISTURE LINGERS IN THE MOUNTAINS THURSDAY NIGHT
INTO FRIDAY AFTERNOON BEFORE DRYING OUT THERE TOO.  THERE IS A BIT
OF A THETA-E AXIS OVER THE FORECAST AREA EARLY WEDNESDAY EVENING...A
BIT OF CAPE TOO.  MORE INSIGNIFICANT THAN YESTERDAYS MODELS
INDICATED.  BY MID EVENING THE NEW AIRMASS MOVES ACROSS THE FORECAST
AREA ENDING THE THREAT OF CONVECTION.  MODELS ARE TRENDING SLOWLY
NORTHWARD WITH THE UPPER CIRCULATION OVER THE LAST SEVERAL RUNS SO
WILL NEED TO PEAR BACK THE POPS A BIT FOR THE FOOTHILLS AND PLAINS.
WILL GO WITH CHANCES THERE.  THE BEST WINDOW FOR PLAINS POPS IS
LATE WEDNESDAY EVENING THROUGH ABOUT MID MORNING THURSDAY.  AFTER
THAT WILL DECREASES PLAINS POPS IN APPROPRIATE AREAS FOR DRYING AND
DOWNSLOPING. IN THE MOUNTAINS...WILL KEEP LIKELY POPS GOING FROM
LATER WEDNESDAY NIGHT THROUGH THURSDAY NIGHT.  THERE IS ACTUALLY
SOME OROGRAPHIC ENHANCEMENT PROGGED THURSDAY AFTERNOON AND NIGHT
HOWEVER THE MOISTURE IS NOT VERY DEEP.  NO HIGHLIGHTS IN THE
MOUNTAINS.  FOR TEMPERATURES...THURSDAYS HIGHS ARE STILL 15 TO 20 C
COLDER THAN WEDNESDAYS.  FRIDAYS HIGHS WARM UP 1-4 C FROM
THURSDAYS.  FOR THE LATER DAYS...SATURDAY THROUGH TUESDAY...MODELS
HAVE WEAK ZONAL FLOW TO WEAK TROUGHING OVER THE FORECAST AREA.
TEMPERATURES STILL LOOK TO BE A BIT BELOW SEASONAL NORMALS.  TRYING
TO PIN-POINT MINOR POPS HERE AND THERE SEEMS TO BE A FUTILE EFFORT.

AVIATION...VFR THROUGH WEDNESDAY.  WINDS WILL BE SOUTHERLY TONIGHT...
THEN TURNING WESTERLY WEDNESDAY.  A COLD FRONT WILL DROP ACROSS THE
AREA WEDNESDAY EVENING WITH A NORTHERLY WIND DEVELOPING.
