...WINTER STORM WARNING FOR THE MOUNTAINS AND FOOTHILLS THIS
AFTERNOON THROUGH FRIDAY NIGHT...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHEAST AND NORTH CENTRAL
COLORADO.

.DAY ONE...TODAY AND TONIGHT

A STRONG AND MOIST SPRING STORM SYSTEM WILL BRING RAIN AND SNOW TO
MUCH OF COLORADO TODAY. THE SNOW WILL BE HEAVIEST ON THE EAST
SLOPES OF THE FRONT RANGE...WHERE 10 TO 24 INCHES OF SNOW MAY
FALL BY FRIDAY MORNING. OTHER MOUNTAIN AREAS...CAN EXPECT 4 TO 10
INCHES OF SNOW. ON THE EASTERN PLAINS...PRECIPITATION WILL MAINLY
BE RAIN...BUT IN AREAS ABOVE 5000 FEET INCLUDING DENVER WILL
MAINLY SEE SNOW THROUGH THE AFTERNOON. PERIODS OF HEAVIER SNOW
THROUGH THIS EVENING COULD CAUSE SIGNIFICANT ACCUMULATIONS IN
AREAS SOUTH OF DENVER AND NEAR THE FOOTHILLS WHERE 4 TO 8 INCHES
OF SNOW WILL BE POSSIBLE. FOR THE REST OF DENVER AREA...UP TO 4
INCHES OF SNOW WILL BE POSSIBLE THROUGH TONIGHT.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

THE STORM SYSTEM WILL CONTINUE TO AFFECT COLORADO ON FRIDAY AND
MAY LINGER INTO SATURDAY. PERIODS OF SNOW WILL CONTINUE IN THE
MOUNTAINS AND FOOTHILLS ON FRIDAY AND MAY BE HEAVY AT TIMES.
ADDITIONAL ACCUMULATIONS OF 6 TO 12 INCHES WILL OCCUR WITH
LOCALLY HIGHER AMOUNTS POSSIBLE IN THE MOUNTAINS OF LARIMER AND
BOULDER COUNTIES. OVER THE PLAINS...THERE WILL BE PERIODS OF RAIN
ALONG WITH A FEW THUNDERSTORMS. THERE ALSO LOOKS TO BE A SLIGHT
RISK OF SEVERE WEATHER ACROSS THE FAR EASTERN PLAINS DURING THE
AFTERNOON WITH LARGE HAIL AND POSSIBLY A TORNADO. SOME SNOW MAY
BE MIXED IN WITH THE RAIN EARLY FRIDAY MORNING ALONG THE FRONT
RANGE BUT ACCUMULATIONS WILL ONLY BE AROUND AN INCH OR SO ON
GRASSY AREAS.

FOR FRIDAY NIGHT INTO SATURDAY THE STORM SYSTEM WILL BE OVER
EASTERN COLORADO. DEPENDING ON EXACTLY WHERE THIS SYSTEM IS
CENTERED COULD LEAD TO MORE PRECIPITATION IN SOME AREAS ESPECIALLY
CLOSER TO THE WYOMING BORDER. TEMPERATURES WILL BE WARM ENOUGH FOR
PRECIPITATION TO FALL AS RAIN OVER THE PLAINS.

THE SYSTEM SHOULD FINALLY MOVE EAST OF THE AREA BY SATURDAY
NIGHT INTO SUNDAY. ANOTHER WEAKER SYSTEM MAY AFFECT THE AREA LATE
SUNDAY NIGHT INTO MONDAY BRINGING ANOTHER CHANCE OF
PRECIPITATION.


.SPOTTER INFORMATION STATEMENT...

SNOWFALL REPORTS FROM SPOTTERS WILL BE APPRECIATED.
