.SHORT TERM...(THIS EVENING THROUGH MONDAY)
ISSUED AT 314 PM MDT SUN APR 26 2015

RAIN AND SNOW CONTINUE ACROSS NORTHEASTERN AND NORTH CENTRAL
COLORADO AS AN UPPER LOW OVER NEW MEXICO WRAPS MOISTURE AROUND
OVER THE STATE AND SURFACE HIGH PRESSURE OVER THE GREAT PLAINS
KEEPS UPSLOPE FLOW GOING. IMPRESSIVE RAINFALL AMOUNTS HAVE BEEN
REPORTED OVER THE PLAINS BOTH SINCE LAST NIGHT AS WELL AS TODAY.
AREAS OVER SOUTHEASTERN WELD...MORGAN...AND EASTERN ARAPAHOE AND
ADAMS COUNTIES HAD UP TO 3 INCHES OF RAIN OVERNIGHT THROUGH THIS 
MORNING. TODAY HAS SEEN AROUND AN INCH ALREADY FALLING OVER THE 
SOUTHERN AND WESTERN DENVER SUBURBS. SOUTHEASTERLY FLOW FUNNELED 
INTO PARK COUNTY WHERE IT UPSLOPED AGAINST THE MOSQUITO 
RANGE...SNOWFALL RATES OF 2 TO 4 INCHES PER HOUR WERE OBSERVED 
TODAY. OVERALL...THIS SYSTEM SEEMS TO HAVE TRENDED SLIGHTLY FURTHER 
SOUTH AND A BIT QUICKER. BELIEVE WE HAVE SEEN THE HEAVIEST RAIN AND 
SNOW FALL RATES THIS AFTERNOON. 

UPSLOPE FLOW WILL CONTINUE OVERNIGHT BUT WEAKEN IN STRENGTH.
EXPECT RAIN AND SNOW TO CONTINUE WITH SNOW LEVELS LOWERING FROM
THE CURRENT 8500 FEET DOWN TO NEAR 7500 FEET. THIS WILL ALLOW A
RAIN AND SNOW MIX DOWN AS FAR AS 6500 FEET. THIS MAY ALLOW THE
PALMER DIVIDE TO ACCUMULATE AN INCH OR SO OF SNOW. AN ADDITIONAL
2 TO 5 INCHES ARE EXPECTED TO FALL TONIGHT OVER THE HIGH
ELEVATIONS OF THE FRONT RANGE AS WELL AS SOUTH PARK. ACROSS THE
PLAINS...RAIN AND LOW CLOUDS WILL PREVAIL OVERNIGHT WITH LIGHTER
RAINFALL AMOUNTS THROUGH THE NIGHT. UPSLOPE FLOW WILL ALLOW FOR
MORE WIDESPREAD RAIN ALONG THE URBAN CORRIDOR WHERE AS THE FAR
EASTERN PLAINS WILL BE MORE SPOTTY. 

AS THE UPPER LOW PULLS FARTHER AWAY MONDAY...RAIN AND SNOW WILL BE
DECREASING THROUGH THE MORNING...AND LIKELY BE ONLY ISOLATED TO SCATTERED
SHOWERS IN THE AFTERNOON. CLEARING CLOUDS WILL ALLOW FOR SOME
WARMING...BUT ONLY LOOK FOR HIGHS IN THE 50S. SNOW LEVELS WILL
GROW FROM 7500 FT IN THE MORNING TO NEAR 10000 FEET BY THE
AFTERNOON. EXPECT ONLY ANOTHER TRACE TO 2 INCHES TOMORROW MORNING
OVER THE HIGH TERRAIN AS THE WINTER STORM WARNING COMES TO AN END
BY NOON. 

.LONG TERM...(MONDAY NIGHT THROUGH SUNDAY)
ISSUED AT 314 PM MDT SUN APR 26 2015

ANY LINGERING SHOWERS WILL GRADUALLY END IN AND NEAR THE FRONT
RANGE I-25 CORRIDOR MONDAY EVENING AS THE AIRMASS DRIES AND
STABILIZES. STILL CANT RULE A FEW SHOWERS HOLDING ON THE MOUNTAIN
TOPS OVERNIGHT BUT OVERALL DRYING SHOULD OCCUR. THERE IS SOME MID
LEVEL MOISTURE SO DONT THINK SKIES WILL TOTALLY CLEAR OUT
OVERNIGHT. IN FACT...ANOTHER WEAK WAVE WILL DROP SOUTHWARD AND
COULD PRODUCE A FEW SHOWERS IN THE NORTHERN BORDER AREA LATE IN
THE NIGHT. AS LONG AS SKIES DONT CLEAR SUFFICIENTLY...TEMPS SHOULD
HOLD ABOVE FREEZING AND LIMIT FOG DEVELOPMENT. WILL WATCH THIS
OVER THE NEXT 24 HOURS.

TUESDAY WILL BE MAINLY DRY ALTHOUGH ONCE AGAIN SHOULD STILL SEE A
COUPLE SHOWERS OVER THE MOUNTAINS DUE TO DAYTIME HEATING AND
INSTABILITY. TEMPERATURES WILL GET BACK CLOSE TO NORMAL.  

FOR WEDNESDAY...THE UPPER RIDGE AXIS WILL CENTER ITSELF ACROSS THE
STATE WITH WARMER WEATHER AND MUCH ABOVE NORMAL TEMPS. DONT SEE
ANY RISK OF AFTERNOON SHOWERS WITH THE HEART OF THE RIDGE AXIS
OVER THE FORECAST AREA. 

BY THURSDAY AND FRIDAY HOWEVER...MOISTURE WILL BEGIN TO BUILD
UNDER THE RIDGE. AS A RESULT...SHOULD SEE ISOLATED TO SCATTERED
AFTERNOON AND EVENING SHOWERS AND A FEW STORMS. TEMPERATURES WILL
REMAIN ABOVE NORMAL. THERE SHOULD BE A WEAK WAVE OR TWO BRUSHING
THE AREA TO THE NORTH. THAT WOULD PUSH A COUPLE WEAK FRONTS ACROSS
THE PLAINS WITH ONLY SLIGHT COOLING. MOISTURE WOULD INCREASE AT
THE SAME TIME SO THE IDEA OF ISOLATED TO SCATTERED LATE DAY
SHOWERS AND STORMS WILL REMAIN IN THE FORECAST THROUGH NEXT
WEEKEND.

AND LOWER TO 500 FT TONIGHT. CEILINGS MAY DROP BELOW 500 AT TIMES
AND REDUCE VISIBILITY TO LESS THAN A MILE AT TIMES THIS AFTERNOON
AND EVENING UNDER THE SHOWERS. GUSTY EAST WINDS WILL PREVAIL
THROUGH THIS EVENING BEFORE DECREASING IN SPEED AND BECOMING MORE
NORTHEASTERLY BY MONDAY. CEILINGS ARE EXPECTED TO IMPROVE MONDAY
