AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
240 PM MDT WED JUN 1 2005

.SHORT TERM...TRAILING END OF SHORT WAVE/MID LEVEL FRONT IS JUST
BEGINNING TO MOVE INTO NORTHWEST COLORADO THIS AFTERNOON. DESPITE
THE INCREASE IN MID LEVEL MOISTURE...CONVECTION HAS BEEN SLOW TO
DEVELOP THIS AFTERNOON.  SATELLITE SHOWS A LOT OF TRAPPED MOUNTAIN
WAVES INDICATING POOR INSTABILITY PROFILE.  THIS SHOULD IMPROVE
HOWEVER AS COLD ADVECTION ALOFT AND CONTINUED SURFACE HEATING
DESTABILIZES ATMOSPHERE LATE THIS AFTERNOON.  WILL KEEP PRECIP
CHANCES GOING...WITH HIGHEST THREAT ALONG THE WYOMING BORDER PER Q-G
VERTICAL MOTION FIELDS.  SOME PRECIP MAY LINGER THROUGH THE NIGHT
ESPECIALLY IN THE MOUNTAINS WITH OROGRAPHIC ENHANCEMENT.

FOCUS THEN SHIFTS TO POTENTIAL FOR SEVERE WEATHER TOMORROW.  WEAK
FRONTAL PASSAGE TONIGHT SHOULD SET THE WAY FOR BETTER LOW LEVEL
SHEAR...MOISTURE...AND INSTABILITY.  LOW LEVEL FLOW EXPECTED TO TURN
SOUTHEAST BY AFTERNOON...SETTING UP A DENVER CYCLONE.  LOW LEVEL
DEWPOINTS RISING INTO THE MID/UPPER 40S WOULD YIELD CAPES OF
1000-1500 J/KG.  WHILE THE INSTABILITY IS NOT GREAT...SHEAR IS VERY
IMPRESSIVE WITH 0-6KM SHEAR ABOUT 50 KTS AND 0-3KM HELICITY AROUND
200 M2/S2.  TORNADO POTENTIAL WOULD DEFINITELY BE THERE WITH LOWER
LCLS AND DENVER CYCLONE SETTING UP.

.LONG TERM...CONVECTION ON THE PLAINS WL CONTINUE INTO THE EVENING
HOURS THURSDAY.  GIVEN THE WLY FLOW ALF AND AXIS OF MSTR ACRS THE
FAR ERN PLAINS WOULDNT BE SURPRISED IF TSTMS ORGANIZE INTO AN MCS
ACRS WRN NEBR AND KS.  FOR OUR AREA...STORM ACTIVITY SHOULD DCRS AFT
SUNSET...BUT UNTIL THEN THE PSBLITY OF SVR ACTIVITY WL BE OF PRIMARY
CONCERN ACRS THE ERN PLAINS.  LATER THURS NGT/FRI MRNG...ANOTHER
SURGE MAY MAKE IT INTO THE PLAINS.  SOME STRATUS MAY FORM ACRS THE
PLAINS IF ENUF RAIN OCCURS TO THE NORTHEAST...BUT FOR NOW...WL KP
THE PTLY CLDY FORECAST FOR FRIDAY MRNG.

SHOULD BE A DOWNTURN IN CONVECTION FRIDAY AS COMPARED TO THURSDAY.
CROSS SECTIONS INDG SUBSTANTIALLY LESS MSTR WITH SOME SUBSIDENCE NR
THE FTHILLS IN THE AFTN.  CURRENT LOW POPS SHOULD SUFFICE.  TEMPS WL
BE A LTL WRMR DUE TO MORE SUN IN THE MRNG AND ELY AFTN DISTRICTWIDE.

LOOKING AHD TO THE WKND AND BEYOND...UPR TROF OVR MT AND IDAHO WL
RMN QUASISTATIONARY FOR THE NEXT SVR DAYS LEAVING THIS FORECAST AREA
WITH PREVAILING SOUTHWESTERLY FLOW. A COUPLE OF DISTURBANCES SHOULD
BE ENUF TO IGNITE AFTN CONVECTIONS SAT AND AGAIN SUNDAY.  AFTER THE
WKND...A WK THERMAL TROF MAY FORM MONDAY AND TUESDAY ALG THE FNT
RANGE WITH SLGTLY WRMR TEMPS AND DRIER WX.  COOLER AND STORMY WX MAY
RETURN FOR WED AND BEYOND NEXT WEEK.
