133 PM MDT WED JUN 9 2010

.SHORT TERM...TONIGHT THROUGH FRIDAY
TONIGHT...ABUNDANT LOW LEVEL MOISTURE HAS ADVECTED NORTHWARD
ACROSS OUR COUNTIES WITH MIDDAY DEW POINTS WELL INTO THE 50S EAST
OF INTERSTATE 25. STILL EXPECTING SCATTERED THUNDERSTORMS TO
DEVELOP AS THE AFTERNOON PROGRESSES...FOCUSED ALONG THE LOW LEVEL
INSTABILITY AND THETA-E RIDGE AXES NORTH-SOUTH ALONG INTERSTATE
25. MID LEVEL CLOUDS WILL LIMIT INSTABILITY THOUGH. WITH ADEQUATE
WIND SHEAR AND INSTABILITY...A FEW OF THE THUNDERSTORMS PRIMARILY
EAST OF INTERSTATE 25...WILL LIKELY BECOME SEVERE THIS AFTERNOON
AND EVENING. WITH LOSS OF DAYTIME HEATING AND LIMITED LIFT
ALOFT...SHOWERS AND THUNDERSTORMS WILL DECREASE IN COVERAGE AND
INTENSITY BY LATE THIS EVENING...WITH SCATTERED SHOWERS ON TAP
ACROSS OUR NORTHERN AND EASTERN COUNTIES AFTER MIDNIGHT. WILL
ADD PATCHY FOG TO EASTERN ZONES LATE TONIGHT AND EARLY THURSDAY
MORNING WITH FAVORABLE BOUNDARY LAYER MOISTURE IN PLACE.

THURSDAY...LEE SURFACE LOW INTENSIFIES ACROSS NORTHEAST COLORADO
WITH A FRONTAL BOUNDARY ACROSS OUR SOUTHEAST COUNTIES IN THE
AFTERNOON. WILL AGAIN SEE SCATTERED AFTERNOON THUNDERSTORMS
DEVELOP NEAR AND BEHIND THE FRONTAL BOUNDARY WITH A FEW STRONG TO
SEVERE THUNDERSTORMS POSSIBLE ALONG THE LOW/MID LEVEL THETA-E
RIDGE AND INSTABILITY AXES...AS DEPICTED BY THE STORM PREDICTION
CENTER'S DAY 2 OUTLOOK. IT WILL BE QUITE WARM EAST OF THE LARAMIE
RANGE WITH HIGHS FROM 85 TO 90...WITH 60S AND 70S IN OVER THE
HIGHER TERRAIN WEST OF THE RANGE.

THURSDAY NIGHT...EXPECT SCATTERED SHOWERS AND SOME THUNDERSTORMS IN
THE WAKE OF THE COLD FRONT WITH MOIST EAST TO NORTHEAST UPSLOPE
FLOW AND SHORTWAVE TROUGH MOVING ACROSS THE REGION. WILL ALSO SEE
AREAS OF FOG DEVELOP IN THE WAKE OF THE COLD FRONT...PRIMARILY
EAST OF INTERSTATE 25.

FRIDAY...IT WILL BE A COOLER AND DAMP DAY WITH SCATTERED SHOWERS
AND THUNDERSTORMS. SOUTHWEST FLOW ALOFT WILL RIDE OVER THE MOIST
NORTHEAST UPSLOPE FLOW AT LOW LEVELS. HIGH TEMPERATURES FROM THE
MID 50S TO NEAR 70 DEGREES DUE TO CLOUD COVER AND PRECIPITATION.

&&

.LONG TERM...FRIDAY NIGHT THROUGH WEDNESDAY
THE 12Z GFS...GEM AND ECMWF MODELS CONTINUE TO HAVE A GOOD
HANDLE ON THE NEXT LATE SEASON STORM AFFECTING OUR CWA FRIDAY
THROUGH MONDAY. THE FLOW ALOFT SPLITS INTO A NORTHERN AND
SOUTHERN STREAM. IN THE SOUTHERN STREAM...THE CLOSED MID/UPPER
LOW OVER THE GREAT BASIN FRIDAY NIGHT REMAINS IN THAT GENERAL
VICINITY BEFORE FINALLY EJECTING NORTHEASTWARD ACROSS CO...WY AND
UT SUNDAY AND SUNDAY NIGHT. MEANWHILE...NORTHERN STREAM HEIGHTS
BUILD OVER ALBERTA AND SASKATCHEWAN CANADA WITH A LARGE AMPLITUDE
RIDGE TAKING SHAPE. A SHORTWAVE TROUGH MOVES OVER THE NORTHERN
PLAINS SUNDAY AND SUNDAY NIGHT. BOTH FACTORS RESULT IN THE SLOW
MOVEMENT OF THE MID/UPPER LOW. THE 12Z ECMWF SEEMS TO HAVE BETTER
RUN TO RUN CONSISTENCY...AND IS FURTHER NORTH AND FASTER WITH THE
EASTWARD PROGRESSION OF THE TROUGH ACROSS THE CWA MONDAY NIGHT AND
TUESDAY. SIGNIFICANT BOUNDARY LAYER UPSLOPE FLOW DEVELOPS OVER THE
CWA FRIDAY THROUGH SATURDAY WITH SURFACE LOW PRESSURE SITUATED
SOUTH OF THE CWA. SURFACE HIGH PRESSURE SLOWLY MOVES SOUTHEAST
FROM THE NORTHERN ROCKIES TO THE CENTRAL PLAINS SUNDAY AND MONDAY.
SYNOPTIC LIFT WILL ALSO BE ENHANCED BY 300 MB DIVERGENCE OVER THE
AND MID LEVEL FRONTOGENESIS. THE MODELS CONTINUE TO SHOW WIDESPREAD
PRECIPITATION THROUGH SUNDAY EVENING AS WELL AS COOLER TEMPERATURES.
RAINFALL AMOUNTS FROM FRIDAY THROUGH SUNDAY WILL AVERAGE BETWEEN
0.25 AND 0.75 INCHES...WITH AMOUNTS IN EXCESS OF AN INCH A GOOD
POSSIBILITY. THIS PREDICTED RAINFALL WILL EXACERBATE THE CURRENT
BANKFULL OR FLOODING RIVERS...RESULTING FROM RECENT SNOW MELT FROM
THE SNOWY AND SIERRA MADRE RANGES. HIGHS SATURDAY WILL BE IN THE
40S AND 50S AND EVEN COOLER OVER THE MOUNTAINS. SNOW WITH AMOUNTS
LESS THAN AN INCH MAY ACCUMULATE OVER THE MOUNTAINS ABOVE 9000
FT... ESPECIALLY SATURDAY NIGHT AND SUNDAY MORNING. A SOMEWHAT
DRIER AND WARMER AIR MASS BEGINS ON TUESDAY WITH THE DEVELOPMENT
OF A SURFACE LEE TROUGH ALONG THE EASTERN WYOMING BORDER. ISOLATED
CONVECTION WILL BE POSSIBLE TUESDAY AND WEDNESDAY AFTERNOON AND
EVENING OVER NORTHERN AND EASTERN PORTIONS OF THE CWA.

&&

.AVIATION...18Z TAF ISSUANCE
VFR CONDITIONS WILL PREVAIL THIS AFTERNOON AND EVENING. BREEZY
SOUTHWESTERLY WINDS WEST OF THE LARAMIE RANGE AND SOUTHEASTERLY
WINDS EAST OF THE RANGE WILL PREVAIL THIS AFTERNOON. ISOLATED
THUNDERSTORMS WILL DEVELOP THIS AFTERNOON AND INCREASE IN
COVERAGE AND INTENSITY AS THEY MOVE EAST. SOME OF THE STORMS WILL
PRODUCING STRONG GUSTY WINDS...HAIL AND HEAVY RAINFALL...RESULTING
IN BRIEF MVFR VSBYS/CIGS. THE SHOWERS AND STORMS MAY LINGER
THROUGH THE EVENING EAST OF INTERSTATE 25... FOLLOWED BY A FEW
SHOWERS. BOTH THE SREF AND NAM NUMERICAL GUIDANCE CONTINUE TO
PREDICT MVFR TO OCNL IFR CIGS WITH BRIEF MVFR VSBYS. GIVEN THIS
CONSISTENT TREND...CONFIDENCE NOW HIGH ENOUGH TO INCLUDE AT
KCYS...KBFF...KSNY...KCDR AND KAIA.

SNOW MELT AND RECENT/FORECAST PRECIPITATION. THE FIRE DANGER WILL
REMAIN LOW THROUGH THE WEEKEND.
