AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
414 AM MDT WED APR 17 2013

.SHORT TERM...STILL A RATHER COMPLEX WEATHER SCENARIO FOR
NORTHEAST AND NORTH CENTRAL COLORADO. WATER VAPOR LOOP SHOWS A
DEEP BUT ELONGATED UPPER LEVEL TROUGH BEGINNING TO PUSH MORE
EASTWARD ACROSS THE GREAT BASIN AND NORTHERN ROCKIES THIS MORNING.
THERE WAS A LARGE AREA OF MODERATE Q-G VERTICAL MOTION AHEAD OF
THIS TROUGH AXIS...AND THIS WILL SHIFT EAST ACROSS THE FORECAST
AREA TODAY BRINGING WIDESPREAD SNOW.

INITIALLY...THE AIRMASS IS ONLY MOIST IN THE LOW LEVELS OVER THE
PLAINS. THIS WILL KEEP FREEZING DRIZZLE IN THE FORECAST UNTIL
DEEPER MOISTURE AND LIFT ARRIVE LATER THIS MORNING. THERE WERE
SIGNS OF THIS DEEPER MOISTURE ARRIVING FROM THE WEST...WITH
COOLING CLOUD TOPS NOTED THE LAST COUPLE HOURS OVER THE WESTERN
HALF OF COLORADO. THE DEEPER CLOUDS AND SNOW SHOULD ARRIVE ACROSS
THE FRONT RANGE FOOTHILLS BY EARLY/MID MORNING AND THEN SPREAD
EASTWARD OVER THE PLAINS LATER THIS MORNING THROUGH THE AFTERNOON.

WITH REGARD TO SNOW AMOUNTS...THE GFS AND CANADIAN WERE STILL THE
MOST AGGRESSIVE WITH SNOW ACCUMULATIONS WHILE THE NAM AND MOST
MESOSCALE MODELS FOLLOWING THE NAMS LEAD WITH LIGHTER ACCUMS. THE
ECMWF PRETTY MUCH SPLIT THE DIFFERENCE. GIVEN THE ELONGATED TROUGH
AND SOME SIGN OF SPLITTING ENERGY AS SEEN IN THE FORECAST Q-G
VERTICAL MOTION FIELDS LATER THIS AFTERNOON/EVENING...CURRENT
THINKING IS WE WILL END UP CLOSER TO THE SLIGHTLY LOWER
EC/NAM/SREF AVERAGES. DESPITE THIS...WE MAY STILL END UP WITH A
SIGNIFICANT WINTER WEATHER EVENT GIVEN A COUPLE FACTORS.
ONE...THERE IS ALREADY SNOW COVERING THE GROUND ALONG AND NORTH OF
THE I-76 CORRIDOR SO ANY NEW SNOW THAT FALLS WILL BE EASILY BLOWN
ABOUT. TWO...STRONG NORTH WINDS OF 20-30 MPH WITH GUSTS TO 40-50
MPH CAN BE EXPECTED ON THE PLAINS. THIS SHOULD CREATE CONSIDERABLE
BLOWING/DRIFTING SNOW AND NEAR BLIZZARD CONDITIONS ESPECIALLY IN
LOCALES WITH PRE-EXISTING SNOW COVER. THERE IS STILL CONSIDERABLE
UNCERTAINTY WITH REGARD TO IMPACTS AT THIS TIME SO WILL MAINTAIN
A BLIZZARD WATCH FOR THE EASTERN PLAINS WITH POSSIBLE MARGINAL
SNOW ACCUMULATIONS IN AREAS THAT HAVE LITTLE/NO PRE-EXISTING SNOW
COVER.

IN THE FRONT RANGE METRO AREAS...WINDS WILL LIKELY BE STRONG
ENOUGH TO PRODUCE CONSIDERABLE BLOWING/DRIFTING SNOW AND HIGHER
IMPACTS GIVEN EXISTING SNOW COVER AND COLDER TEMPERATURES ALLOWING
FOR MORE SNOW ACCUMULATION ON ROADS. THIS WILL VERY LIKELY DEPEND
ON SNOW INTENSITY BUT THERE IS STILL SOME POTENTIAL FOR AN UPGRADE
OF THE ADVISORY TO A WINTER STORM WARNING. THE AFTERNOON COMMUTE
LOOKS NASTY.

THE ONLY CHANGE TO CURRENT HIGHLIGHTS WILL BE TO DELAY THE START
TIME A COUPLE HOURS FOR LOCATIONS EAST OF I-25 GIVEN A SLIGHTLY
SLOWER ARRIVAL OF DEEPER MOISTURE.

.LONG TERM...THE DEPARTING STORM SYSTEM WILL LEAVE THE STATE UNDER
NORTHWEST FLOW THURSDAY. SOME MOISTURE WILL STILL BE EXITING THE
STATE AND WILL LIKELY SEE SOME LIGHT SNOW REMAINING OVER THE FAR
EASTERN PLAINS IN THE MORNING AS WELL AS SOME OROGRAPHIC SNOW
LASTING OVER THE MOUNTAINS THROUGH THE AFTERNOON. TEMPERATURES
WILL STAY COLD...IN THE 30S FOR THE PLAINS AND IN THE 20S FOR THE
MOUNTAINS. NORTHERLY WINDS WILL STILL BE A BIT STRONG DURING THE
DAY...AROUND 15 TO 25 MPH WITH SOME GUSTS AS HIGH AS 40 MPH OVER
THE PLAINS...WHICH WILL CAUSE AREAS OF BLOWING SNOW. THOSE WINDS
SHOULD DIMINISH IN THE EVENING EXCEPT WHERE THEY WILL BE STAYING
GUSTY OUT OF THE WEST IN THE FOOTHILLS.

FRIDAY WILL SEE A SLIGHT WARM UP AND MAINLY DRY WEATHER...BUT
MOISTURE WILL BE INCREASING OVER THE NORTHERN MOUNTAINS LATER IN
THE DAY THROUGH THE NIGHT AS A WEAK DISTURBANCE NEARS THE STATE IN
THE NORTHWEST FLOW. TEMPERATURES SHOULD WARM SIGNIFICANTLY WITH
WARM ADVECTION MOVING IN...AND THE INTENSE APRIL SUN HELPING TO
MELT ANY REMAINING SNOW. READINGS OF UPPER 40S TO NEAR 50 OVER THE
PLAINS AND LOW TO MID 30S FOR THE MOUNTAINS ARE EXPECTED. STILL
ABOUT 10 DEGREES COOLER THAN NORMAL. THE WEAK DISTURBANCE IS
EXPECTED TO INCREASE SHOWERS OVER THE MOUNTAINS AND BRING A SLIGHT
CHANCE OF RAIN SHOWERS TO THE PLAINS SATURDAY AFTERNOON.
TEMPERATURES WILL BE SLIGHTLY WARMER THAN FRIDAY.

SUNDAY...A STRONGER DISTURBANCE WILL BE MOVING OVER THE NORTHERN
ROCKIES AND NEARING THE STATE IN THE NORTHWEST FLOW ALOFT. THIS
DISTURBANCE IS THEN EXPECTED...AS PROGGED BY THE GFS...ECMWF AND
GEM...TO DEEPEN AND DROP SOUTH OVER THE STATE BY MONDAY. THIS WILL
BRING YET ANOTHER ROUND OF COLDER TEMPERATURES AND A CHANCE OF
SNOW FORECAST AREA WIDE STARTING SUNDAY AND LASTING INTO
TUESDAY. HAVE INCREASED POPS FOR THIS PERIOD AND LOWERED
TEMPERATURES TO SHOW THIS BETTER CONFIDENCE IN THE FORECAST. SEEMS
LIKE THE ONGOING ACTIVE WEATHER PATTERN OF APRIL WILL CONTINUE
INTO NEXT WEEK.

&&

.AVIATION...LIGHT FREEZING DRIZZLE/FLURRIES WILL CONTINUE EARLY
THIS MORNING WITH MORE WIDESPREAD AND HEAVIER SNOW THEN DEVELOPING
LATE THIS MORNING INTO EARLY AFTERNOON. IFR/LIFR CONDITIONS WILL
PREVAIL. CYCLONIC CONVERGENCE ZONE WILL FLUSH SOUTH WITH ARRIVAL
OF COLD FRONT BY EARLY AFTERNOON WITH STRONGER NORTH WINDS WITH
GUSTS UP TO 30-35 KTS...STRONGEST AT KDEN. CONSIDERABLE
BLOWING/DRIFTING SNOW EXPECTED WITH STRENGTH OF WINDS. SNOW SHOULD
DECREASE AFTER 03Z-06Z WITH AN ENDING 09Z-12Z AND VFR CONDITIONS
DEVELOPING. TOTAL SNOW ACCUMULATIONS MOST LIKELY WILL BE IN THE
4-6 INCH RANGE.

&&

.BOU WATCHES/WARNINGS/ADVISORIES...
BLIZZARD WATCH FROM 2 PM MDT TODAY THROUGH LATE TONIGHT FOR
COZ041-042-044>046-048>051.

WINTER STORM WARNING UNTIL MIDNIGHT MDT TONIGHT FOR COZ031-033-

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

.DAY ONE...TODAY AND TONIGHT

AN UPPER LEVEL STORM SYSTEM OVER THE GREAT BASIN WILL MOVE INTO
COLORADO TODAY AND THEN ACROSS THE EASTERN PLAINS TONIGHT...
BRINGING WIDESPREAD SNOW AND BLOWING SNOW TO THE AREA. SNOW WILL

BLOWING AND DRIFTING SNOW.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

BY THURSDAY THE SYSTEM WILL EXIT THE AREA WITH LIGHT SNOW
DIMINISHING OVER THE FAR EASTERN PLAINS AND OROGRAPHIC SNOW IN
THE MOUNTAINS. TEMPERATURES WILL BE WARMING FRIDAY AND INTO THE

FORECAST AREA.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY OR TONIGHT...HOWEVER
SNOWFALL REPORTS WILL BE APPRECIATED.
