AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
318 PM MDT WED OCT 5 2011

.SHORT TERM...A DEEP UPPER LEVEL LOW WILL SHIFT FROM THE WEST COAST
TONIGHT TO THE GREAT BASIN TOMORROW. SOUTHWEST FLOW ALOFT WILL
INCREASE AHEAD OF IT WITH A 140 JET MOVING OVER SOUTHERN COLORADO
THURSDAY AFTERNOON. FOR THE REST OF THIS AFTERNOON AND
EVENING...MID LEVELS CONTINUE TO BE SOMEWHAT MOIST AND UNSTABLE.
WATER VAPOR SHOWING DRIER AIR MOVING ACROSS EASTERN COLORADO AT
THIS TIME. DO EXPECT A FEW SHOWERS AND PERHAPS A COUPLE OF STORMS
TO FORM...HOWEVER COVERAGE WILL BE LESS THAN YESTERDAY. MAY HAVE A
FEW WEAK SHOWERS CONTINUE OVERNIGHT AND INTO TOMORROW MORNING OVER
THE HIGH COUNTRY. WILL HAVE LOW POPS IN THE FORECAST FOR THIS.

PACIFIC COLD FRONT AND UPWARD VERTICAL MOTION WILL MOVE ACROSS
THE MOUNTAINS TOMORROW AFTERNOON. SNOW LEVEL WILL START OFF AROUND
11000 FEET AND QUICKLY FALL DURING THE AFTERNOON HOURS BEHIND THE
FRONT. BY SUNSET...EXPECT THE SNOW LEVEL TO BE AROUND 8000 FEET.
TOTAL SNOW FALL AMOUNTS THURSDAY AFTERNOON THROUGH THURSDAY NIGHT
WILL BE 3 TO 6 INCHES IN THE NORTH CENTRAL MOUNTAINS WITH UP TO 4
INCHES POSSIBLE IN THE MOUNTAINS OF SUMMIT COUNTY. WILL ISSUE A
WINTER WEATHER ADVISORY FOR ZONES 31 AND 33 FOR THURSDAY AFTERNOON
AND THURSDAY NIGHT.

THIS SYSTEM WILL PRODUCE A SURFACE LOW OVER EASTERN MONTANA AND
EASTERN WYOMING. A DRY LINE WILL SET UP ALONG THE COLORADO/KANSAS
BORDER TOMORROW AFTERNOON. STRONG SOUTHERLY WINDS WILL DEVELOP
OVER THE PLAINS THURSDAY. WITH STRONG MIXING AND STRONG WINDS
ALOFT...GUSTS TO 50 TO 60 MPH WILL BE POSSIBLE. WILL ISSUE A HIGH
WIND WATCH FOR LINCOLN AND EASTERN ELBERT COUNTIES WHERE THE
STRONGEST WINDS ARE EXPECTED.

THE STRONG AND DRY SOUTHWEST FLOW WILL KEEP MOST OF THE PLAINS DRY
THURSDAY. MAY SEE A FEW LIGHT SHOWERS NEAR THE FOOTHILLS THAT GET
BLOWN ACROSS THE DIVIDE. THE BEST CHANCE ACROSS THE LOWER ELEVATIONS
WILL BE NEAR THE WYOMING BORDER WHERE THE SOUTHERLY FLOW WILL
PRODUCE UPSLOPE FLOW ALONG CHEYENNE RIDGE.

.LONG TERM...MODEL DIFFERENCES PERSIST IN THE HANDLING OF THE TAIL
END OF THE UPPER TROUGH. GFS HAS BEEN FAIRLY PERSISTENT IN BRINGING
AN ELONGATED LOW FAIRLY QUICKLY ACROSS COLORADO ON SATURDAY...ECMWF
REMAINS STRONGER AND SLOWER...QUITE A BIT SLOWER IN SOME RUNS. 12Z
NAM HAD A DEVELOPING LOW MOVING ACROSS SOUTHEASTERN COLORADO
SATURDAY WHICH LOOKED JUST RIGHT FOR A PERIOD OF DECENT ISENTROPIC
LIFT OVER NORTHEASTERN COLORADO AND A FOOT OF SNOW ON THE EAST
SLOPES OF THE FRONT RANGE...18Z RUN IS SLOWER AND A BIT FURTHER
SOUTH. EVEN AFTER THROWING OUT THE EXTREMES STILL LOTS OF
UNCERTAINTY WITH THE DETAILS...WILL SLOW DOWN THE TIMING IN THE
FORECAST A BIT AND RAISE POPS TO LIKELY MOST PLACES...WILL START
SATURDAY OFF WITH A CONSENSUS QPF THAT LOOKS AS GOOD AS ANYTHING.
THIS PRODUCES SEVERAL INCHES OF SNOW IN THE MOUNTAINS BUT DOES NOT
HAVE BIG AMOUNTS IN THE FOOTHILLS.

ONCE THIS SYSTEM MOVES OUT THE WEATHER LOOKS PRETTY QUIET AGAIN WITH
WNW FLOW ALOFT. SOME SHORTWAVE ENERGY IN THE FLOW THAT PASSES NORTH
OF US ABOUT TUESDAY...MAYBE WITH LITTLE EFFECT BUT COULD PROVIDE A
LITTLE COOLING AND A FEW MOUNTAIN SHOWERS AS IT PASSES.

&&

.AVIATION...GUSTY SOUTHERLY WINDS WILL CONTINUE INTO THE EVENING
HOURS WITH GUSTS TO 30 KNOTS POSSIBLE. VERY SMALL CHANCE FOR A
SHOWER OR STORM. IF ONE DEVELOPS IT WILL BE HIGH BASED AND ONLY
PRODUCE LIGHT RAIN. GUSTY OUTFLOW WINDS WILL BE POSSIBLE IF
CONVECTION FORMS. THE SOUTHERLY WINDS WILL TEMPORALLY DECREASE
OVERNIGHT BEFORE INCREASING AGAIN ON THURSDAY. WINDS WILL BE EVEN
STRONGER AND DEVELOP EARLIER THURSDAY WITH GUSTS TO 40 KNOTS
POSSIBLE.

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

.DAY ONE...TODAY AND TONIGHT

WINDY CONDITIONS WILL PREVAIL ACROSS THE EASTERN PLAINS AND PALMER
DIVIDE AREA ONCE AGAIN THIS AFTERNOON...WITH SOUTHERLY WINDS GUSTING
TO AROUND 35 MPH. THIS WILL RESULT IN ELEVATED FIRE DANGER ALTHOUGH
HUMIDITIES WILL BE SLIGHTLY HIGHER THAN YESTERDAY.

OTHERWISE...LOOK FOR SCATTERED SHOWERS AND A FEW THUNDERSTORMS TO
DEVELOP THIS AFTERNOON AND CONTINUE INTO EARLY EVENING. THE STORMS
WILL PRODUCE BRIEF MODERATE RAINFALL ALONG WITH GUSTY WINDS. SNOW
LEVEL WILL BE BETWEEN 10 AND 11 THOUSAND FEET. LITTLE IF ANY
ACCUMULATION WILL OCCUR THROUGH TONIGHT.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

ANOTHER MILD AND WINDY DAY IS EXPECTED ON THURSDAY.  STRONG
SOUTHWESTERLY FLOW ALOFT AND DEVELOPING LOW PRESSURE OVER THE
NEBRASKA PANHANDLE WILL CAUSE GUSTY WINDS TO DEVELOP ON THE PLAINS
AS TEMPERATURES CLIMB INTO THE MID 70S.  RELATIVE HUMIDITY LEVELS
WILL DROP TO THE UPPER TEENS WHICH WILL COMBINE WITH THE GUSTY WINDS
TO PRODUCE HAZARDOUS FIRE WEATHER CONDITIONS.  IN THE MOUNTAINS...AN
APPROACHING UPPER LEVEL WEATHER DISTURBANCE WILL PRODUCE A MIX OF
RAIN AND SNOW.  SNOW LEVELS MAY DROP TO 8500 FEET IN THE AFTERNOON.

FROM FRIDAY THROUGH SUNDAY...MUCH COOLER AND WETTER WEATHER IS
EXPECTED ACROSS NORTH CENTRAL AND NORTHEAST COLORADO.  THE UPPER
LEVEL WEATHER DISTURBANCE MOVING OVER THE STATE WILL PRODUCE THE
CHANCE OF RAIN ON THE PLAINS AND A MIX OF RAIN AND SNOW IN THE
MOUNTAINS.  SNOW LEVELS WILL DROP INTO THE FOOTHILLS. PEOPLE
PLANNING OUTDOOR ACTIVITIES IN THE MOUNTAINS THIS WEEKEND SHOULD BE
PREPARED FOR COLD AND WET WEATHER.

WARMER AND DRIER WEATHER IS EXPECTED TO RETURN TO THE REGION MONDAY
AND TUESDAY.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY OR TONIGHT.
