NORTHEAST AND NORTH CENTRAL COLORADO AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER COLORADO
322 AM MDT TUE JUL 3 2001

SHORT TERM DISCUSSION:  CURRENT SATELLITE AND PROFILER DATA SHOW THE
UPPER RIDGE CENTERED TO THE WEST OF THE CWA TODAY WHICH WILL KEEP US
IN NORTHWESTERLY FLOW ALOFT.  CONSEQUENTLY TODAY SHOULD BE RATHER
SIMILAR TO THE LAST COUPLE OF DAYS.  THE ONLY DIFFERENCES MIGHT BE A
TAD MORE AFTERNOON THUNDERSTORM ACTIVITY AND VERY SLIGHTLY COOLER
HIGH TEMPERATURES.

LONG TERM DISCUSSION:  SUSPECT THAT THE MAJORITY OF THE CONVECTION
SHOULD DIE WITH THE SUN THIS EVENING.  HOWEVER...THE 03/06Z ETA AND
MM5 RUNS BOTH WANT TO BRING A BATCH OF CONVECTIVE PRECIPITATION INTO
THE NORTHEAST PART OF THE CWA BETWEEN 00Z AND 06Z WITH A HINT OF
SOME STRATUS BEHIND IT DURING THE EARLY MORNING HOURS WEDNESDAY.  IT
WILL BE INTERESTING TO SEE IF THIS INDEED WORKS OUT.  FOR WEDNESDAY
THE ETA HAS QUITE A BIT MORE PRECIPITATION AMOUNT/COVERAGE FORECAST
THAN FOR TUESDAY AND THIS SEEMS OK.  D3D TRAJECTORIES SUGGEST MOST
PARCELS ENDING UP IN THE CWA AT 05/00Z WILL PROBABLY HAVE SUFFICIENT
TIME AND ASCENT TO PICK UP AT LEAST SOME OF THE SUBTROPICAL MOISTURE
LURKING ABOUT TO OUR SOUTH AND WEST.  MOST OF THIS WILL LIKELY BE IN
THE MID AND UPPER TROPOSPHERIC LEVELS.  LOW LEVEL TRAJECTORIES IN
THE FAR NORTHEAST CORNER OF COLORADO HOWEVER ARE COMING FROM THE
SOUTHEAST AND SO THE LOW LEVELS MAY EVEN BE ABLE TO MOISTEN SOME OUT
THERE.  INDEED PRECIPITABLE WATER VALUES THERE ARE IN EXCESS OF ONE
INCH BY THIS EVENING AND REMAIN THERE THROUGH WEDNESDAY.

FURTHER DOWN THE LINE THE LATEST MRF IS CONTINUING THE TREND FROM
LAST NIGHT OF PUSHING THE UPPER RIDGE TO THE SOUTHERN PLAINS BY
FRIDAY PROVIDING A SUBSTANTIAL SOUTHERLY COMPONENT TO THE MEAN FLOW
OVER COLORADO.  THIS WOULD ALLOW SUBTROPICAL MOISTURE TO MOVE IN...
INCREASING THE THREAT OF AFTERNOON/EVENING RAINS AND DECREASING THE
MAXIMUM TEMPERATURES.  CURRENT FORECAST HAS THINGS WELL IN HAND. ET

.DEN...NONE.
