AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
330 PM MDT TUE JUL 3 2007

.SHORT TERM...THE COLD FRONT THAT PASSED OVER THE NORTHEAST COLORADO
EARLIER TODAY HAS STALLED OVER THE PALMER DIVIDE.  A BAND OF SHOWERS
HAS DEVELOPED ALONG THE STALLED FRONT WHICH WILL CONTINUE FOR THE
NEXT FEW HOURS.  ADDITIONAL MOISTURE HAS BEEN MOVING INTO THE
FORECAST AREA FROM THE NORTHEAST...AND THIS IS BEGINNING TO FUEL
THUNDERSTORMS OVER THE NORTHERN FRONT RANGE FOOTHILLS.  THE SHEAR
PROFILE IS FAVORABLE FOR THUNDERSTORMS TO REMAIN ORGANIZED AFTER
THEY DEVELOP THIS EVENING.  CONVECTIVE INHIBITION ON THE PLAINS IS
STILL SUFFICIENT TO SUPPRESS MOST CONVECTION.

FOR WEDNESDAY...LOW LEVEL MOISTURE IS EXPECTED TO CONTINUE
INCREASING THROUGH THE DAY AS EASTERLY WINDS CONTINUE.  TEMPERATURES
WILL BE MARKEDLY COOLER AND BY AFTERNOON...SHOWERS SHOULD DEVELOP
OVER THE FOOTHILLS AND THEN SPREAD EASTWARD TO THE ADJACENT PLAINS.

.LONG TERM...FOR WEDNESDAY NIGHT INTO THURSDAY THE UPPER RIDGE WILL
REMAIN OVER THE WEST WITH A WEAK NLY FLOW ALOFT OVER THE CWFA.  ELY
FLOW AT THE LOW AND MID LVLS MAY CONFINE MOST OF THE TSTM ACTIVITY
TO AREAS IN AND NEAR THE HIGHER TERRAIN.  FCST CAPES WILL RANGE FM
500-1000 MB WEDNESDAY EVENING...WITH SIMILAR VALUES ON FRIDAY.  THE
BEST LOW LVL MSTR AND TSTM POTENTIAL WILL BE OVER SRN PORTIONS OF
THE CWFA WITH TEMERATURES NEAR NORMAL.  THE UPPER RIDGE WILL  BUILD
IN FM THE WEST AND NORTH WITH A WARMER AND DRIER TREND EXPECTED
HEADING INTO THE WEEKEND.  THIS ALREADY REFLECTED IN THE GRIDS SO
ONLY MINOR ADJUSTMENTS TO THE GRIDS EXPECTED AT THIS TIME.

&&

.AVIATION...AFTERNOON AND EVENING SHOWERS OVER THE FOOTHILLS THIS
EVENING MAY PRODUCE OUTFLOW BOUNDARIES THAT REACH KDEN WITH SHIFTING
WINDS.  CONVECTIVE ACTIVITY IS EXPECTED TO DISSIPATE AS THE SUN GOES
DOWN.  VFR CONDITIONS ARE EXPECTED OVERNIGHT AND WEDNESDAY MORNING.
EASTERLY LOW LEVEL WINDS DEVELOPING ON WEDNESDAY WILL INCREASE LOW
LEVEL MOISTURE THROUGH THE DAY.  AFTERNOON HEATING MAY PRODUCE
ENOUGH INSTABILITY FOR SHOWERS WITH HEAVY RAINFALL TO DEVELOP.

.BOU WATCHES/WARNINGS/ADVISORIES...NONE.
