THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF CENTRAL...EAST
CENTRAL...SOUTH CENTRAL AND SOUTHEAST COLORADO.

.DAY ONE...TODAY AND TONIGHT

AREAS OF FREEZING FOG...DENSE AT TIMES...WILL PERSIST ACROSS
PORTIONS OF THE SAN LUIS VALLEY...INCLUDING ALAMOSA...THROUGH 10 AM
THIS MORNING.

A STRONG PACIFIC JET STREAM WILL MOVE OVER THE AREA TONIGHT. A
COMBINATION OF STRONG WINDS ALOFT AND STRONG DOWNSLOPE PRESSURE
GRADIENTS WILL RESULT IN HIGH WIND POTENTIAL. THE POTENTIAL FOR HIGH
WINDS WILL INCREASE THIS EVENING...PEAK BETWEEN 11 PM AND 5 AM...AND
THEN DECREASE TUESDAY MORNING. THE PRIMARY AREA FOR CONCERN IS ALONG
AND NEAR THE EASTERN MOUNTAINS AND WEST OF INTERSTATE 25. IN THE
MOUNTAINS... WEST WINDS 30 TO 50 MPH WITH GUSTS OVER 75 MPH WILL
BE POSSIBLE. ACROSS THE LOWER ELEVATIONS ADJACENT TO THE
MOUNTAINS...WEST WINDS 20 TO 40 MPH WITH GUSTS OVER 60 MPH WILL BE
POSSIBLE.

SNOW SHOWERS WILL BEGIN TO DEVELOP ALONG THE CONTINENTAL DIVIDE
AFTER MIDNIGHT TONIGHT.  LOCAL ACCUMULATIONS OF AN INCH OR 2 WILL
BE POSSIBLE ACROSS THE HIGHER TERRAIN OF THE SAWATCH AND MOSQUITO
RANGES BY TUESDAY MORNING.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

FORECAST MODELS ARE IN GOOD AGREEMENT ON MOVING COLD AND SNOWY
WEATHER INTO SOUTHERN COLORADO...ARRIVING ALONG THE CONTINENTAL
DIVIDE TUESDAY AND MOVING INTO THE EASTERN MOUNTAINS AND PLAINS
TUESDAY NIGHT. A LARGE LOW PRESSURE SYSTEM WILL CARVE OUT OVER THE
WESTERN UNITED STATES DURING THIS PERIOD...ALLOWING ARCTIC AIR TO
PLUMMET SOUTHWARD INTO COLORADO. THE COMBINATION OF MOIST PACIFIC
AIR ALOFT...AND VERY COLD ARCTIC AIR AT THE SURFACE...WILL PROVIDE
THE NECESSARY INGREDIENTS FOR AN EXTENDED PERIOD OF VERY COLD
TEMPERATURES AND PERIODS OF SNOW OVER SOUTHERN COLORADO.

THE EXCEPTIONAL ASPECT OF THIS ARCTIC OUTBREAK WILL BE THE LENGTH
OF TIME IT STICKS AROUND. SOUTHERN COLORADO IS FREQUENTLY VISITED
BY ARCTIC AIR MASSES DURING THE WINTER...BUT THEY USUALLY ONLY
STICK AROUND FOR A DAY OR TWO. THIS ONE LOOKS LIKE IT WILL MOVE IN
LATE TUESDAY AND LINGER THROUGH AT LEAST SUNDAY. THE AIR WILL BE
VERY COLD DURING THIS PERIOD WITH HIGHS LIKELY NOT OUT OF THE
TEENS AND 20S MOST DAYS...AND LOWS RANGING FROM 10 BELOW ZERO TO
10 ABOVE.

THERE IS ALSO GOOD SNOWFALL POTENTIAL WITH THIS STORM.  WHILE IT
IS STILL TOO EARLY TO NAIL DOWN SPECIFIC AMOUNTS...IT IS A GOOD
BET THAT THE MOUNTAINS WILL SEE AT LEAST A FOOT OR TWO OF NEW SNOW
DURING THIS EVENT...WHILE THE LOWER ELEVATIONS CAN EXPECT TO SEE
SEVERAL INCHES OF SNOWFALL.

TAKE TIME TO PREPARE FOR THE COLD NOW.  THIS WILL BE AN EXCEPTIONAL
PERIOD OF COLD FOR SOUTHERN COLORADO.  PREPARE YOUR HOME...AUTO OR
BUSINESS. CHECK YOUR FURNACE. INSULATE EXPOSED WATER PIPES.  MAKE
SURE YOUR CAR HAS A STRONG BATTERY...PROPER ANTIFREEZE PROTECTION
AND A GOOD SET OF ALL SEASON OR SNOW TIRES. MAKE SURE YOUR KIDS
DRESS WARMLY BEFORE HEADING TO SCHOOL AND GIVE YOUR PETS ADEQUATE
SHELTER FROM THE COLD. THIS WILL BE AN UNUSUALLY LONG PERIOD FOR
SOUTHERN COLORADO TO BE IN THE DEEP FREEZE. GET READY FOR IT NOW
WHILE THE TEMPERATURES ARE STILL MILD.

.SPOTTER INFORMATION STATEMENT...

WEATHER CONDITIONS THAT MEET REPORTING CRITERIA FOR SPOTTERS WILL BE
POSSIBLE ALONG AND NEAR THE MOUNTAINS AND WEST OF INTERSTATE 25
TONIGHT.
