AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
340 AM MDT SUN JUN 25 2006

.SHORT TERM DISCUSSION...UPPER RIDGE HAS SHIFTED WESTWARD LEAVING
LIGHT NLY FLOW OVER OUR AREA. NOT MUCH TO FOCUS ON TODAY AS
SHORTWAVE DROPPING ACROSS THE NORTHERN PLAINS LOOKS TO HAVE MINIMAL
IMPACT. PREFER NAM HANDLING OF THIS WITH LIGHTER WINDS...THERE IS
ALMOST NO SURFACE REFLECTION OF THIS FEATURE AT PRESENT. THE NORTH
TO NORTHEAST WINDS WILL BRING IN DRIER AIR...WHICH MAY PREVENT
THUNDERSTORMS ON THE PLAINS TODAY. IT STILL SHOULD WARM UP ENOUGH
FOR STORMS TO FORM ALONG THE FOOTHILLS AND MOVE SOUTHWARD. COULD BE
FAIRLY RAINY IN THE FOOTHILLS DUE TO THE STORM MOTIONS...BUT
AVAILABLE MOISTURE AND INSTABILITY ARE BOTH FAIRLY TAME SO FLASH
FLOODING THREAT SEEMS LOW...PERHAPS SOME AREAS COULD GET AN INCH OR
TWO FROM TRAINING. A BIT MORE MOISTURE HAS SLIPPED OVER THE FRONT
RANGE FROM LAST NIGHTS CONVECTION AND A WEAK EASTERLY FLOW. THIS
WILL MOSTLY MIX OUT BUT THE LOW POPS WE SHOW SLIPPING A BIT FURTHER
WEST SEEM APPROPRIATE. SO...TRIMMED BACK POPS/CLOUD COVER ON THE
PLAINS A LITTLE...AND LOWERED TEMPERATURES A BIT ACROSS THE BOARD
TONIGHT WITH DRIER AIR AND EARLIER CLEARING EXPECTED.

.LONG TERM DISCUSSION...MODELS SIMILAR IN KEEPING UPPER LEVEL RIDGE
OVER THE WESTERN U.S. WITH A NORTHERLY FLOW OVR ERN COLORADO THROUGH
THE PERIOD. THIS WILL ALLOW FOR A COUPLE OF SURGES TO SLIDE ACROSS
THE EASTERN PLAINS WITH EASTERLY FLOW PREVAILING. THUS...MAIN FOCUS
FOR CONVECTION SHOULD OCCUR ALONG FOOTHILLS AND ADJACENT PLAINS WITH
LESS FURTHER EAST. FIRST SURGE STILL EXPECTED SOMETIME TUESDAY
AFTERNOON...WITH THE SECOND SURGE EARLY THURSDAY. LATEST GFS QG
VERTICAL VELOCITY PROGS STILL HINT AT A SHORTWAVE MOVING ACROSS THE
AREA EARLY THURSDAY...WHICH COULD AID IN ENHANCING THE SURGE.
CURRENT GRIDS SEEM TO SHOW THIS TREND...WITH ONLY MINOR CHANGES
NEEDED. FORECAST SOUNDINGS INDICATE MEAGER CAPES...GENERALLY AROUND
1000 J/KG. THUS...SEVERE THREAT LOOKS MINIMAL. ACROSS MOUNTAINS...
MODELS BEGINNING TO SHOW MOISTURE INCREASE FROM THE SOUTH BY
AFTERNOON TUESDAY...WHICH CONTINUES THROUGH THE PERIOD. THIS COULD
LEAD TO A BETTER CHANCE FOR RAINFALL BY MID WEEK. GRIDS SHOW THIS
TREND AS WELL...SEE NO REASON TO ALTER. OVERALL...ONLY MINOR CHANGES
NEED TO CURRENT GRIDS.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHEAST AND NORTH CENTRAL
COLORADO.

.DAY ONE...TODAY AND TONIGHT

SCATTERED THUNDERSTORMS ARE EXPECTED IN THE LATE AFTERNOON AND
EVENING HOURS TODAY...MAINLY ALONG THE EAST SLOPES OF THE FRONT
RANGE. SLIGHTLY COOLER AND DRIER AIR WILL LIMIT THE EASTWARD EXTENT
OF TODAYS ACTIVITY. STORMS WILL TEND TO DEVELOP OVER THE FRONT RANGE
FOOTHILLS AND DRIFT SOUTHWARD. THIS COULD LEAD TO LOCALLY HEAVY
RAINFALL ALONG THE FOOTHILLS. THE AMOUNT OF MOISTURE AVAILABLE AND
THE INSTABILITY IS LIMITED...SO THE THREAT OF FLASH FLOODING IS LOW.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

THERE WILL BE A CHANCE OF AFTERNOON AND EVENING SHOWERS AND
THUNDERSTORMS EACH DAY.  AT THIS TIME...THE THREAT OF SEVERE
WEATHER IS MINIMAL.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY OR TONIGHT.
