...SPRING STORM TO AFFECT NORTHERN COLORADO THROUGH FRIDAY
NIGHT...

.A STORM SYSTEM WILL MOVE VERY SLOWLY FROM THE FOUR CORNERS AREA
INTO EASTERN COLORADO FRIDAY. MEANWHILE VERY MOIST AIR WILL MOVE
INTO EASTERN COLORADO AND BE LIFTED BY THE STORM AND BY UPSLOPE
WINDS. HEAVY WET SNOW WILL BECOME WIDESPREAD IN THE MOUNTAINS AND
FOOTHILLS THIS MORNING AND CONTINUE THROUGH FRIDAY AFTERNOON.
DEPENDING ON THE EXACT TRACK AND SPEED OF THE STORM SYSTEM HEAVY
SNOW COULD LINGER INTO FRIDAY NIGHT AS WELL. ACCUMULATIONS OF 12
TO 24 INCHES ARE EXPECTED WITH UP TO 36 INCHES IN SOME FAVORED
EAST SLOPE LOCATIONS.

ALONG THE FRONT RANGE URBAN CORRIDOR THERE WILL BE A MIX OF RAIN
AND SNOW WITH MOSTLY RAIN ACROSS THE PLAINS. CURRENT EXPECTATIONS
ARE THAT AREAS ALONG THE FRONT RANGE URBAN CORRIDOR WILL SEE FROM
2 TO 4 INCHES OF WET SNOW WITH LOTS OF MELTING ON ROADWAYS. UP
TO 8 INCHES OF SNOW IS POSSIBLE NEAR THE FOOTHILLS...OVER THE
PALMER DIVIDE...AND NEAR THE WYOMING BORDER ON INTERSTATE 25. IF
TEMPERATURES END UP BEING A FEW DEGREES COLDER THAN CURRENTLY
FORECAST THEN AREAS NEAR THE FOOTHILLS AND SOUTH OF DENVER COULD
HAVE MUCH HEAVIER SNOW. THE GREATEST THREAT OF THAT WOULD BE
OVERNIGHT TONIGHT.
