.UPDATE...
ISSUED AT 1017 AM MST MON JAN 26 2015

NO NEED TO MAKE NAY CHANGES TO THE FORECAST AT THIS TIME. THE
VISIBILITIES AT KREMMLING AIRPORT ARE STILL LESS THAN A MILE IN
FOG...BUT SATELLITE IMAGERY SHOWS ONLY A LIMITED AREA TO THE NORTH
OF TOWN THAT HAS LOW CLOUDS. THE REMAINDER OF THE FORECAST AREA IS
CLOUD-FREE WITH GENERALLY LIGHT WINDS. TEMPERATURES HAVE WARMED TO
NEAR 60 IN THE DENVER-BOULDER AREA...ON THERE WAY UP TO AROUND 70
DEGREES. TEMPERATURES ARE A LITTLE COOLER ALONG THE SOUTH PLATTE
RIVER ACROSS WELD AND MORGAN COUNTIES...BUT INSOLATION SHOULD BE
STRONG ENOUGH TO WARM THEM UP THROUGH THE AFTERNOON.

UPDATE ISSUED AT 635 AM MST MON JAN 26 2015

UPDATED 1ST PERIOD FORECAST FOR LOW CLOUDS AND AREAS OF FOG IN
PARTS OF GRAND COUNTY/ZONE 32. KREMMLING HAS BEEN REPORTING FOG
THE PAST SEVERAL HOURS. NOW DENSE FOG IN THE PAST HOUR WITH THE

.SHORT TERM...(TODAY THROUGH TONIGHT )
ISSUED AT 343 AM MST MON JAN 26 2015

OUR LATE JANUARY THAW CONTINUES TODAY AS A STRONG UPPER RIDGE
MAKES ITS SLOW EASTWARD PROGRESS ACROSS THE STATE. A SHRINKING BATCH
OF HIGH CLOUDS SLIDING DOWN THE FRONT SIDE OF THIS RIDGE WILL
QUICKLY PASS OVER ERN SECTIONS OF THE CWA EARLY THIS MORNING. BY
MID TO LATE MORNING SHOULD SEE A RETURN TO CLEAR SKIES WHICH
SHOULD PERSIST THROUGH THE OVERNIGHT HOURS WITH THE UPPER RIDGE
PASSING OVERHEAD. TEMPERATURES THE BIG HEADLINER TODAY WITH
AFTERNOON READINGS LIKELY TO CLIMB INTO THE UPPER 60S/LOWER 70S
ALONG THE FRONT RANGE...MID 60S FARTHER OUT ON THE PLAINS AND
BALMY 40S AND LOWER 50S IN THE HIGH COUNTRY. MAY COME WITHIN A DEG
OR TWO OF TYING THE RECORD OF 73F AT DENVER. SHOULD ALSO SEE
ANOTHER NIGHT OF VERY MILD TEMPS WITH 30S AND LOWER 40S ON THE
PLAINS...WARMEST NEAR THE FOOTHILLS...AND BALMY TEENS AND LOWER
20S IN THE HIGH COUNTRY.

.LONG TERM...(TUESDAY THROUGH SUNDAY)
ISSUED AT 343 AM MST MON JAN 26 2015

THE STRONG RIDGE ALOFT WILL SHIFT ACROSS COLORADO ON TUESDAY AND
INTO THE CENTRAL PLAINS TUESDAY NIGHT. ANOTHER UNSEASONABLY WARM
DAY EXPECTED WITH TEMPERATURES NEAR 70 DEGREES ON THE PLAINS. THE
UPPER LOW NOW OVER THE SOUTHERN CALIFORNIA COAST WILL WEAKEN AS IT
MOVES NORTHEAST AND ACROSS COLORADO ON WEDNESDAY. THIS WILL
PROVIDE SOME MOISTURE AND OROGRAPHIC FLOW INTO THE MOUNTAINS FOR A
CHANCE OF SNOW SHOWERS. AS THE TROF MOVES ACROSS THE STATE AN
ASSOCIATED COLD FRONT WILL SWEEP ACROSS EASTERN COLORADO WITH AN
INCREASING NORTHWEST DOWNSLOPE FLOW. THIS WILL KEEP NORTHEAST
PLAINS DRY BUT WITH COOLER TEMPERATURES.

THE WEATHER PICTURE IS A BIT MORE MUDDLED ON THURSDAY AND FRIDAY
AS THE FLOW ALOFT BECOMES MORE OF A SPLIT FLOW PATTERN WITH
THE STRONGER SOUTHERN BRANCH DEVELOPS A CLOSED LOW OVER ARIZONA
BY LATE FRIDAY. THE GFS SHOWS A BIT DEEPER TROF WITH THE NORTHERN
BRANCH WHILE EUROPEAN SOLUTION IS WEAKER WITH MORE RIDGING OVER
COLORADO. WILL MAINTAIN LOW POPS DURING THESE PERIODS ALONG WITH
THE CONTINUED COOLING TREND. TEMPERATURES WILL RETURN TO MORE
SEASONAL NORMALS FOR THURSDAY AND BEYOND. DRIER AND WARMER AGAIN
BY SUNDAY AS RIDGING BUILDS BACK INTO COLORADO.
