AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
300 PM MDT THU JUN 9 2005

.SHORT TERM...SEVERE THREAT APPEARS TO BE WANING AS THE DRYLINE HAS
SHIFTED INTO KANSAS...HOWEVER THERE IS STILL AN AREA OF WEAK
CONVERGENCE WITH GOOD MOISTURE BACK AS FAR AS STERLING AND AKRON.
EVEN IN THIS REGION THE THREAT APPEARS HIGHEST IN AREAS WITH MORE
SUN...MAINLY YUMA COUNTY SOUTHWARD. TEMPERATURES STRUGGLING ALONG
FRONT RANGE...BUT MOISTURE AND SHEAR ADEQUATE. WE SHOULD STILL SEE A
GOOD ROUND OF THUNDERSTORMS ALONG THE FRONT RANGE...BUT THE SEVERE
THREAT IS MARGINAL FOR THE NEXT FEW HOURS...THEN COOLER AIR COMES IN
FROM THE NORTH. THIS SHOULD INCREASE THE COVERAGE OF STORMS BUT END
THE SEVERE THREAT. QG FORCING THEN APPEARS TO BE THE DOMINANT FACTOR
AS WINDS DECREASE BEHIND THE ABOVE MENTIONED SURGE LATER TONIGHT.
THERE WILL PROBABLY BE SOME LIGHT SHOWERS AROUND...BUT IT LOOKS LIKE
LATE TONIGHT INTO FRIDAY MORNING WILL BE A BREAK IN THE ACTION.
FRIDAY AFTERNOON WILL SEE US IN A WEAK DEFORMATION ZONE WITH MOIST
ADIABATIC LAPSE RATES. MARGINAL...BUT IN A SATURATED AIRMASS THERE
SHOULD BE SOME EMBEDDED STORMS. GIVEN THE ARRANGEMENT OF THE
DEFORMATION ZONE AND LIGHT WINDS...THERE COULD BE A LOCALIZED HEAVY
RAIN THREAT. MAIN CHANGES WERE TO INCREASE POPS IN THE NORTHWEST
PART OF THE AREA OVERNIGHT...THEY HAD BEEN LOWER BUT APPEAR TO BE
FAVORED THIS EVENING. ALSO BROUGHT THE SNOW LEVEL...NOW AROUND 11
THOUSAND FEET...DOWN TO BETWEEN 9 AND 10 THOUSAND FEET OVERNIGHT.

.LONG TERM...FRIDAY NIGHT...THE FIRST OF TWO SHORT WAVE TROFS WILL
BE PASSING TO THE NORTH AND EAST OF THE CWFA.  MOST FVBL POPS WILL
OCCUR BEFORE MIDNIGHT WHERE THERE IS SOME LINGERING QG ASCENT AND
THE MOST FVBL INSTBY.  BEST WINDOW FOR PCPN LOOKS TO BE IN THE LATE
AFTN/EVNG.  AS FOR FRIDAY NIGHT INTO SATURDAY...MDLS SHOW SOME MID
LVL SUBSIDENCE IN THE WAKE OF THIS SYSTEM UNTIL AROUND 18Z.  BY THE
AFTN HOWEVER...SOUTHEASTERLY SFC WINDS START TO INCREASE AHEAD OF
THE NEXT APPROACHING STORM SYSTEM.  BY LATE SATURDAY AFTN...QG
ASCENT WILL BE INCRG FM THE WEST WITH A GOOD SFC CYCLONE PROGGED TO
ESTABLISH.  FCST CAPES OFF THE INTERACTIVE NAM SOUNDINGS RANGE FRM
500-700 J/KG WITH SOME DECENT SHEAR STILL PRESENT.  BEST CHC OF
STRONGER STORMS WILL LIKELY BE OVER SRN AND ERN SECTIONS OF THE
CWFA. FOR THIS REASON WILL MAINTAIN SCT POPS.  THE NEXT SYSTEM IS
PROGGED TO MOVE ACROSS THE CWFA LATE SATURDAY NIGHT INTO SUNDAY.
HAVE AGAIN BUMPED POPS TO A HIGHER SCT CATEGORY.  THIS SYSTEM LOOKS
DEEPER AND STRONGER THAN THE FIRST WAVE WITH BETTER QG ASCENT
THROUGH ABOUT 18Z SUNDAY...IF THE TIMING IS CORRECT.  MDLS ARE
FASTER THAN THE PRVS RUN IN TERMS OF TIMING SO MAIN ADJUSTMENTS TO
THE GRIDS WILL INVOLVE THIS.  BY SUNDAY NIGHT THE GFS KICKS THE
SECOND SYSTEM NORTH AND EAST. FOR THE START OF NEXT WEEK...A DRIER
AND MORE ZONAL FLOW CAN BE EXPECTED AS THE MDLS STILL START TO BRING
AN UPPER LVL RIDGE INTO THE WEST.  THIS IS ALREADY REFLECTED IN THE
GRIDS SO NO BIG CHANGES WILL BE NEEDED IN THE EXTENDED.

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

.DAY ONE...TODAY AND TONIGHT

SEVERE THUNDERSTORMS ARE EXPECTED THIS AFTERNOON IN NORTHEASTERN
COLORADO. THE THREAT IS GREATEST EAST OF A LINE FROM BRIGGSDALE TO
LIMON. A PERSISTENT AREA OF CONVERGING WINDS LIES ACROSS LOGAN AND
WASHINGTON COUNTIES. THIS AREA IS EXPECTED TO BE A FOCUS FOR
THUNDERSTORM DEVELOPMENT THIS AFTERNOON...AND IT MAY SHIFT WESTWARD
TOWARD FORT MORGAN DURING THE AFTERNOON. FROM THIS AREA EASTWARD
THERE IS MUCH BETTER MOISTURE AND ALSO A BETTER WIND PROFILE FOR
SUPERCELL THUNDERSTORM DEVELOPMENT. THE PRIMARY THREATS TODAY WILL
BE VERY LARGE HAIL UP TO BASEBALL SIZE...UP TO 3 INCHES OF RAIN IN
AN HOUR...AND WIND GUSTS TO 70 MPH. IN AREAS FURTHER WEST TO THE
FOOTHILLS THERE IS LESS MOISTURE...SO THE THREAT OF SEVERE WEATHER
IS LOWER. THERE WILL STILL BE ENOUGH INSTABILITY FOR ONE OR TWO
SEVERE THUNDERSTORMS WITH LARGE HAIL AND HEAVY RAIN.  THE THREAT OF
SEVERE WEATHER WILL SHIFT EAST OF THE AREA BY MID EVENING...THOUGH
SHOWER AND THUNDERSTORM ACTIVITY WILL CONTINUE.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

AN UNSETTLED WEATHER PATTERN WILL CONTINUE OVER NORTHERN COLORADO
THROUGH SUNDAY WITH A COUPLE OF UPPER LEVEL LOW PRESSURE SYSTEMS
MOVING ACROSS THE AREA.  THE FIRST ON FRIDAY WILL MAKE SHOWERS AND
THUNDERSTORMS LIKELY ACROSS THE AREA THROUGH THE EVENING.  THE
SECOND ON SATURDAY NIGHT AND SUNDAY WILL PRODUCE SCATTERED SHOWERS
AND THUNDERSTORMS.  AN UPPER RIDGE WILL BEGIN TO MOVE INTO THE ROCKY
MOUNTAINS ON MONDAY AND BRING DRIER AND WARMER WEATHER TO THE AREA
THROUGH WEDNESDAY.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL BE NEEDED AFTER 2 PM.
