...RED FLAG WARNING REMAINS IN EFFECT UNTIL 8 PM MDT THIS
EVENING FOR THE PLAINS ADJACENT TO THE FRONT RANGE...AS WELL AS 
ACROSS ELBERT AND LINCOLN COUNTIES IN NORTHEAST AND EAST CENTRAL 
COLORADO...

A RED FLAG WARNING REMAINS IN EFFECT UNTIL 8 PM MDT THIS EVENING.

THIS INCLUDES THE FOLLOWING FIRE WEATHER ZONES...
IN COLORADO...238...239...240...241...243...245...246...247

WEST WINDS OF 20 TO 30 MPH WILL BE COMMON THIS AFTERNOON...WITH
POTENTIAL GUSTS TO AS HIGH AS 40 MPH. AREAS ALONG THE BASE OF THE
FOOTHILLS MAY EVEN SEE HIGHER GUSTS. DAYTIME RELATIVE HUMIDITIES
WILL ALSO BE QUITE LOW...RANGING FROM 10 TO 20 PERCENT. THE STRONG
WINDS AND VERY LOW HUMIDITIES WILL COMBINE WITH LOW FUEL MOISTURE
TO PRODUCE HIGH AND POSSIBLY EXTREME WILDLAND FIRE DANGER
CONDITIONS THROUGH EARLY THIS EVENING. THESE CONDITIONS ARE
EXPECTED TO SUBSIDE IN THE EVENING WITH WINDS SHIFTING TO THE
NORTHEAST AND WITH RISING HUMDITIES FOLLOWING THE PASSAGE OF A
WEAK COLD FRONT.


DRY AND WINDY CONDITIONS IN AREAS FURTHER OUT ACROSS THE NORTHEAST
PLAINS OF COLORADO WILL ALSO ELEVATE THE FIRE DANGER...ALTHOUGH 
RECENT SNOW COVER HAS LIMITED THE AMOUNT OF DRYING OF FUELS IN
THESE AREA.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A RED FLAG WARNING MEANS THAT CRITICAL FIRE WEATHER CONDITIONS
ARE EITHER OCCURRING OR IMMINENT. PLEASE ADVISE THE APPROPRIATE
OFFICIALS AND FIRE CREWS IN THE FIELD OF THIS RED FLAG WARNING.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
400 AM MDT SAT APR 3 2010

.SHORT TERM...JET LIFTS ACROSS COLORADO TODAY...BRINGING AN AREA OF
LIFT THAT MOVES FROM THE MOUNTAINS THIS MORNING ACROSS THE PLAINS
THIS AFTERNOON. THERE IS A LITTLE POCKET OF COOLER AIR AT MID LEVELS
ALONG WITH THE MOISTURE ASSOCIATED WITH THE LIFT. THOUGH THE
INSTABILITY AND LIFT ARE MODEST...THE WINDS ARE STRONG ENOUGH TO
PRODUCE MODERATE SNOWFALL IN OROGRAPHICALLY FAVORED AREAS. MORE
NORTHERN MOUNTAINS AREAS WILL BE FAVORED BOTH FOR THE MORE WESTERLY
WIND DIRECTION AND BETTER MOISTURE. WINDS ALREADY GUSTING TO 65 MPH
ABOVE TIMBERLINE ON NIWOT RIDGE IN BOULDER COUNTY AND 40 MPH GUSTS
SHOULD BE COMMON...SO I WILL GO AHEAD AND ISSUE A WINTER WEATHER
ADVISORY FOR THE HIGHER MOUNTAIN ZONES EVEN THOUGH THE SNOW IS NOT
EXPECTED TO BE HEAVY.  ON THE PLAINS DOWNSLOPE SHOULD KILL ANY
THREAT OF PRECIPITATION. THE MID LEVEL AIR ON THE SOUTHERN EDGE OF
OUR AREA IS VERY DRY...WITH DEW POINTS IN THE CENTRAL COLORADO
MOUNTAINS AROUND ZERO. MIXING OF THE DRY AIR AND THE WINDS ALOFT
WILL CREATE RED FLAG CONDITIONS ALONG THE SOUTHERN FRINGE OF OUR
AREA TODAY...AND THIS WILL LIKELY EXTEND NORTHWARD ALONG THE BASE OF
THE FOOTHILLS. FORT COLLINS/GREELEY/LIMON ARE MORE MARGINAL BUT WILL
PROBABLY MEET THE CRITERIA AT LEAST BRIEFLY THIS AFTERNOON SO I WILL
GO AHEAD AND INCLUDE THEM IN A RED FLAG WARNING. MOUNTAIN ZONES WILL
HAVE SIMILAR CONDITIONS BUT FUELS ARE STILL DRYING OUT FROM RECENT
SNOW COVER...THOUGH LOWER FOOTHILL AREAS WILL STILL HAVE AN ELEVATED
FIRE DANGER TODAY. AS TODAYS SHORTWAVE PASSES...SURFACE WINDS WILL
BECOME MORE NORTHERLY BY EARLY EVENING AND THE REDUCED MIXING WILL
ALSO CAUSE SPEEDS TO DROP OFF PRETTY QUICKLY.

TEMPERATURES WERE LOWERED A BIT TODAY AND TONIGHT IN A COMPROMISE
BETWEEN OUR OLD FORECAST AND GUIDANCE. WIND IS EXPECTED TO HELP HOLD
TEMPS UP A BIT.

.LONG TERM...A STG SWLY FLOW ALOFT WILL BE OVER THE CWFA ON SUNDAY.
THERE IS SOME WEAK QG ASCENT AOA 700 MB ADVERTISED SUNDAY MORNING
...WITH SOME SHORT WAVE RIDGING IN THE AFTN. SPATIAL CROSS-SECTIONS
KEEP THE BEST MSTR OVER NWRN CO.  WL HEDGE THE BEST POPS IN THE HIGH
COUNTRY THERE AS WELL.  ELSEWHERE STRONG DOWNSLOPE FLOW WL ALLOW FOR
DRY AND MILD CONDITIONS.  SUNDAY NIGHT AND MONDAY...THE NEXT SYSTEM
OFF THE PACIFIC NORTHWEST COAST WL MOVE ONSHORE.  A STRONG SWLY FLOW
ALOFT WILL CONTINUE OVER CO WITH A 100+ KT JETSTREAM OVHD.  MSTR IS
PROGGED TO INCREASE IN THE MTNS ON MONDAY AND THIS ALREADY REFLECTED
IN THE GRIDS.  STRONG DOWNSLOPE FLOW ALOFT WILL KEEP THE NERN PLAINS
DRY AND MILD ON MONDAY.  BOTH THE ECMWF/GFS SWING THE NEXT TROF AXIS
ACROSS NRN CO MONDAY NIGHT INTO TUESDAY WITH A JET MAX OF CLOSE TO
120 KTS MOVE OVER THE CWFA.  SOME WEAK QG ASCENT AROUND 00Z TUESDAY
BUT STG DOWNSLOPE COULD AGAIN NEGATE ANY CHC OF SHOWERS.  ENUF
INSTBY IN THE AFTN HOWEVER FOR SOME HIGH BASED VIRGA. THE TROF
ITSELF IS EXPECTED TO PASS ACRS NRN CO AROUND 12Z TUE WITH THE MID
LEVEL WINDS BECOMING MORE WNWLY FOLLOWING THE PASSAGE OF ITS AXIS.
IN THE MTNS...LGT SNOW AND STG WINDS STILL LOOK ON TRACK SO WL STICK
WITH LIKELY POPS ON TUESDAY. BETTER OROGRAPHIC COMPONENT DEVELOPS AT THA
TIME.  ALG THE FRONT RANGE... THE WINDOW OF PCPN MAY BE FAIRLY
BRIEF.  SPATIAL CROSS SECTIONS INDICATE A STG BORA WIND EVENT
DEVELOPING TOWARDS 12Z TUESDAY.  WL GO WITH BASICALLY 10 PERCENT
POPS FOR MOST OF THE URBAN CORRIDOR AND NERN PLAINS.  BEST CHC OF
PCPN WL BE FURTHER EAST AWAY FM THE FRONT RANGE FOR TUESDAY/TUESDAY
NIGHT.  THE MDLS SHOW STG QG DESCENT DEVELOPING OVER WRN AND SRN
PARTS OF THE CWFA...WITH SOME WEAK QG ASCENT IN THE VICINITY OF THE
TROF ITSELF.  SYSTEM WL BE TOO FAR NORTH TO BRING MUCH PCPN TO NERN
CO...SO BEST CHC OF PCPN WL RESIDE IN THE MTNS.  STG BUT DRIER
NORTHWESTERLY FLOW WL BE OVER CO ON WEDNESDAY/THURSDAY WITH
INCREASING SUBSIDENCE DEVELOPING.  COOLER TEMPERATURES STILL LOOK
OKAY FOR WEDNESDAY...WITH A GRADUAL WARMING TREND FOR THURSDAY INTO
FRIDAY.

.AVIATION...STRONG WEST WINDS WILL DEVELOP BY MIDDAY AND CONTINUE
THROUGH SUNSET. GUSTS TO AROUND 30 KNOTS CAN BE EXPECTED AT KDEN AND
KAPA WITH GUSTS TO 50 KNOTS POSSIBLE OVER AND NEAR THE FOOTHILLS.
EXPECT MECHANICAL TURBULENCE FROM THE GUSTINESS AND CROSSWIND ISSUES
AT KDEN AND KAPA. WIND DIRECTION WILL LIKELY BECOME MORE NORTHWEST
BY LATE AFTERNOON WHICH MAY HELP WITH KDEN CROSSWIND COMPONENT...
THEN LIGHTER NORTH TO NORTHEAST WINDS ARE EXPECTED BY 02Z.

EXPECTED ON THE PLAINS ON SUNDAY WITH JUST A SLIGHT CHANCE OF RAIN
OR SNOW IN THE HIGH COUNTRY.

THE NEXT PACIFIC STORM SYSTEM COULD BRING SIGNIFICANT SNOWFALL TO
THE HIGH COUNTRY AND A CHANCE OF RAIN AND SNOW TO LOWER ELEVATIONS
LATE MONDAY THROUGH TUESDAY NIGHT. IT WILL ALSO TURN WINDY AND
COOLER WITH THE PASSAGE OF THIS STORM SYSTEM.
