AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
1102 AM MDT THU JUN 5 2014

.UPDATE...
ISSUED AT 1102 AM MDT THU JUN 5 2014

WEATHER SITUATION TODAY LOOKS VERY SIMILAR TO YESTERDAY WITH
MODEST INSTABILITY AND FAVORABLE WIND SHEAR PROFILES TO SUPPORT
ORGANIZED THUNDERSTORM FORMATION. PALMER DIVIDE ONCE AGAIN APPEARS
TO BE THE FAVORED LOCATION FOR THE STRONGEST STORMS...BUT HIGH-
RES-RAPID-REFRESH (HRRR) MODEL RUNS HAVE BEEN INDICATING THAT
ADDITIONAL SHOWERS WILL BE POSSIBLE UP THE URBAN CORRIDOR TO THE
WYOMING BORDER. WILL INCREASE POPS THIS AFTERNOON AND EVENING
ACROSS THE PLAINS AND MENTION THE POSSIBILITY OF SEVERE WEATHER
OVER THE PALMER DIVIDE ZONES.

UPDATE ISSUED AT 525 AM MDT THU JUN 5 2014

SOME STRATUS HAS DEVELOPED OVER THE FAR NORTHEAST PLAINS...MAINLY
FROM MORGAN...FAR EASTERN ADAMS AND ARAPAHOE COUNTIES AND INTO
NORTHERN LINCOLN COUNTY. LATEST SATELLITE DOES NOT SHOW MUCH
WESTWARD MOVEMENT. WILL ADJUST CLOUD COVER IN GRIDS TO ACCOUNT
FOR THIS.

&&

.SHORT TERM...(TODAY THROUGH TONIGHT )
ISSUED AT 117 AM MDT THU JUN 5 2014

LARGE MCS IS NOW INTO KANSAS WITH CWA NOW STORM FREE FOR THE TIME.
STILL SOME LINGERING CLOUDINESS OVER FAR EASTERN COLORADO BUT
MAINLY THE MID AND HIGH LEVEL VARIETY. NOT SEEING MUCH IN THE WAY
OF STRATUS/FOG DEVELOPING SO WILL BACK OFF ON SOME OF THAT WITH
REDUCED CLOUD COVER IN UPCOMING ZONES. FAIRLY DECENT TEMPERATURE
AND DEWPOINT SPREADS WITH DEWPOINTS IN THE 40S OVER THE FRONT
RANGE AND 50S OVER FAR EASTERN ZONES UNDER NORTHWEST WINDS.

MAIN CONCERN AGAIN TODAY WILL SEVERE WEATHER POTENTIAL OVER
NORTHEAST COLORADO. WATER VAPOR IMAGERY SHOWING 2 DISTINCT JET
SEGMENTS...ONE OVER SOUTHEAST COLORADO AND THE OTHER OVER FAR
NORTHWEST COLORADO. THE NORTHERN SEGMENT IS PROGGED TO SAG SLOWLY
SOUTHWARD OVER CENTRAL COLORADO THIS AFTERNOON AT 50-60KT. APPEARS
AGAIN THE PALMER DIVIDE AND LOCATIONS SOUTH AND EAST OF DENVER MAY
BE THE FOCUS AGAIN FOR SEVERE STORMS. ELSEWHERE...STORMS WILL BE
MORE ISOLATED BUT STILL THE CHANCE FOR BECOMING SEVERE WITH
SURFACE BASED CAPES FROM 1000-2000J/KG...HIGHEST OVER THE PLAINS.
SIMULATED IMAGERY FROM WRF AND NAM SEE TO PINPOINT
DOUGLAS...ELBERT AND LINCOLN COUNTIES AS THE TARGET AREAS FOR AN
MCS DEVELOPING AGAIN LATER THIS AFTERNOON AND EVENING. THE HRRR
CONCURS WITH INITIAL DEVELOPMENT OVER DOUGLAS COUNTY AT 20-21Z.
MAIN THREAT FROM THESE STORMS WILL BE LARGE HAIL AND DAMAGING
WINDS BUT CAN'T RULE OUT A TORNADO THREAT WITH MCS DEVELOPMENT.
SO BASED ON ABOVE WILL HAVE THE HIGHER POPS OVER SOUTHERN PORTIONS
OF CWA.

.LONG TERM...(FRIDAY THROUGH WEDNESDAY)
ISSUED AT 117 AM MDT THU JUN 5 2014

STILL LOOKS LIKE A MOIST AND UNSETTLED PERIOD FOR THE REMAINDER OF
THIS WEEK...WITH A WEAK TROUGH APPROACHING THE AREA. AS THE TROUGH
NEARS...DUE TO LIFT AND A ROBUST THETA E RIDGE OVER EASTERN
COLORADO...FRIDAY LOOKS LIKE THE WETTEST DAY OF THE PERIOD ON THE
PLAINS...ALONG WITH A SLIGHT RISK OF SEVERE WEATHER. THE TROUGH
LOOKS LIKE IT MOVES THROUGH LATE SATURDAY OR SUNDAY...WHICH WILL
DRAG COOLER AIR ACORSS NORTHEAST COLORADO...RESULTING IN MAX
TEMPS IN THE 70S FOR NORTHEAST COLORADO THIS WEEKEND. WARMER AND
MORE STABLE AIR WILL MOVE ACROSS THE AREA EARLY NEXT WEEK. THERE
WILL STILL BE SOME THUNDERSTORM ACTIVITY OVER THE HIGHER TERRAIN
EACH DAY...THE PLAINS SHOULD BE DRY ON MONDAY.

&&

.AVIATION...(FOR THE TAFS THROUGH 18Z FRIDAY MORNING)
ISSUED AT 1102 AM MDT THU JUN 5 2014

WITH PALMER DIVIDE AS THE MAIN FOCUS FOR AFTERNOON AND EVENING
THUNDERSTORM DEVELOPMENT...AND ADDITIONAL THUNDERSTORMS POSSIBLY
MOVING OUT OF NORTHERN JEFFERSON OR BOULDER COUNTIES...WILL
MENTION A FEW HOURS OF THUNDERSTORMS AT EACH OF THE DENVER
AIRPORTS. AFTER THE EVENING SHOWERS MOVE EASTWARD ONTO THE
PLAINS...AREAS ALONG THE FRONT RANGE WILL RETURN TO DRY
NORTHWESTERLY FLOW WHICH SHOULD ONCE AGAIN KEEP OUTFLOW GENERATED
STRATUS CLOUDS EAST OF THE DENVER AREA AIRPORTS. WILL NOT MENTION
ANY LOW CLOUDS OR FOG IN THE LATTER PORTIONS OF THE TAFS.

&&

.HYDROLOGY...
ISSUED AT 117 AM MDT THU JUN 5 2014

SHORT TERM HYDRO...THE SLOW COOLING TREND WILL CONTINUE AND WILL
KEEP RIVERS/STREAMS AT STEADY PEAK LEVELS AND SOME SLOW DECREASE
IN OVERALL LEVELS OVER NEXT 24 HOURS.

LONG TERM HYDRO...THE MAIN FOCUS FOR PRECIPITATION WILL BE ON THE
PLAINS THE REST OF THIS WEEK...ANY HEAVY RAIN SHOULD FALL ON THE
PLAINS AND NOT IN THE FOOTHILLS. FLOW ALOFT WILL CONTINUE TO BE
ZONAL...SO THUNDERSTORMS SHOULD MOVE ALONG AS WE SAW LAST EVENING.

THERE IS STILL QUITE A BIT OF SNOW TO MELT IN THE NORTHERN
MOUNTAINS...SO AREA RIVERS WILL CONTINUE TO RUN HIGH AND FAST INTO
NEXT WEEK.
