AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PUEBLO CO
252 PM MDT MON APR 26 2010

.SHORT TERM...

(TONIGHT AND TUESDAY)

...MAIN SHORT TERM CONCERN IS THE POTENTIAL FOR FREEZING
TEMPERATURES AND PATCHY FROST OVERNIGHT ACROSS THE PLAINS...ALONG
WITH SOME LOW CLOUDS...

USED MAINLY THE NAM12 FOR SHORT RANGE PRODUCTS DUE TO ITS DETAIL.

THE WEAK UPPER LEVEL DISTURBANCE HAS MOVED SOUTHEAST OUT OF THE AREA
THIS AFTERNOON...LEAVING ENOUGH MOISTURE AND COLD AIR TO CAUSE A FEW
SHOWERS OVER THE EASTERN MOUNTAINS AROUND COLORADO SPRINGS. THESE
SHOWERS ARE EXPECTED TO DIE OFF BY MID EVENING. CLOUDINESS IS
DECREASING OVER THE AREA WITH SKIES EXPECTED TO BECOME MOSTLY CLEAR
ACROSS MOST AREAS BY MIDNIGHT. TEMPERATURES WILL DROP TO AROUND OR A
LITTLE BELOW FREEZING OVERNIGHT...ALLOWING PATCHY FROST TO
FORM...MAINLY IN LOW LYING AREAS OF THE EASTERN PLAINS. PERSONS WITH
DELICATE PLANTS SHOULD TAKE STEPS TO PROTECT THEM.

WITH THE CLEARING SKIES...SOME PATCHY LOW CLOUDS ARE ALSO EXPECTED
TO FORM...AND PERSIST UNTIL AN HOUR OR TWO AFTER SUNRISE TUESDAY.
LATER TUESDAY...TEMPERATURES SHOULD WARM TO AROUND OR A LITTLE
ABOVE NORMAL ACROSS MOST AREAS WHICH DO NOT HAVE SNOW COVER. BY
LATE AFTERNOON...BREEZY CONDITIONS ARE EXPECTED TO DEVELOP AS THE
WINDS ALOFT SHIFT INTO THE WEST AHEAD OF A NEW STORM SYSTEM WHICH
IS APPROACHING THE GREAT BASIN BY TUESDAY NIGHT. -JKH-

.LONG TERM...

(TUESDAY NIGHT THROUGH MONDAY)

MODELS IN AGREEMENT THROUGH THE FIRST HALF OF THE EXTENDED
FORECAST BEFORE DIFFERENCES SHOW UP FOR THE WEEKEND. HIGH PRESSURE
AHEAD OF A STRONG STORM SYSTEM WILL BE OVER THE ROCKIES TUESDAY
AND EARLY WEDNESDAY. THE HIGH PRESSURE WILL MOVE EAST INTO THE
CENTRAL PLAINS BY WEDNESDAY AFTERNOON AS FLOW TURNS SOUTHWESTERLY
AHEAD OF THE APPROACHING STORM SYSTEM. WARM DRY AIR ALOFT WILL MIX
DOWN ALONG THE LEE SLOPES AND EASTERN PLAINS ALLOWING TEMPERATURES
TO WARM INTO THE LOWER 80S. THE MAIN IMPACT WEDNESDAY AFTERNOON
WILL BE WINDS. WINDS AT 700 MB PEAK BY 00Z THURS APPROACHING 60
KTS ACROSS THE RATON RIDGE AND SOUTHEASTERN PLAINS. WITH MIXING
AND DOWNSLOPE WINDS ACROSS THE PLAINS WILL BE STRONG. WOULD NOT BE
SURPRISED TO SEE GUSTS TO 45 KTS WEDNESDAY AFTERNOON. DRIER AIR
WILL ALSO WORK INTO THE REGION LOWERING AFTERNOON HUMIDITY VALUES
ACROSS THE PLAINS INTO THE TEENS. FUELS ARE CURRENTLY BELOW
CRITICAL STATUS SO NOT PLANNING ON FIRE WEATHER HIGHLIGHTS. A LEAD
VORT MAX WILL BE MOVING INTO WESTERN COLORADO BY WEDNESDAY
AFTERNOON WHERE SHOWERS AND THUNDERSTORMS WILL DEVELOP ALONG THE
CONTINENTAL DIVIDE AND WILL PERSIST THROUGH THE OVERNIGHT HOURS.

A STRONG COLD FRONT OUT OF THE PACIFIC NORTHWEST WILL TRACK
SOUTHEAST ACROSS COLORADO WEDNESDAY NIGHT INTO THURSDAY MORNING.
MODEL TEMPERATURES PROFILES BRING NEARLY 10-15 DEGREES OF COOLING
BEHIND THE FRONT AT 700 MB. EXPECT SNOW LEVELS TO DROP QUICKLY
BEHIND THE FRONT WITH SNOW FAVORED ON THE NORTH AND WEST FACING
SLOPES OF THE CONTINENTAL DIVIDE. CURRENTLY EXPECTING TO SEE
SEVERAL INCHES OF SNOWFALL THROUGH THURSDAY MORNING OVER THE
CENTRAL MOUNTAINS WHERE THE BEST OROGRAPHIC EFFECTS WILL BE
PRESENT. GFS IS BREAKING OUT A BAND OF PRECIPITATION ALONG THE
FRONT THAT WILL DROP SOUTH ACROSS THE PLAINS DURING THE DAY ON
THURSDAY. EXPECT THE MOST FAVORED AREA TO SEE PRECIPITATION TO BE
ALONG THE PALMER DIVIDE.

BEYOND THURSDAY...UPPER LOW AND ASSOCIATED BROAD TROUGH WILL
REMAIN STATIONARY OVER THE NORTHERN PLAINS INTO THE DESERT
SOUTHWEST. MODELS HANDLE THE EVOLUTION AND MOVEMENT OF THE SYSTEM
DIFFERENTLY. TRENDED WITH THE GFS WHICH AS SOME ENSEMBLE SUPPORT
THROUGH THE WEEKEND. BOTH THE GFS AND ECMWF WANT TO DEVELOP A
SECONDARY LOW PRESSURE CENTER OVER THE DESERT SOUTHWEST HEADING
INTO THE WEEKEND. GFS SLOWER ON THIS SOLUTION THAN THE ECMWF.
EXPECT UNSETTLED WEATHER TO CONTINUE ACROSS THE WESTERN AND
CENTRAL MOUNTAINS THROUGH THE WEEKEND. THERE WILL ALSO BE PERIODS
OF PRECIPITATION ACROSS THE PLAINS AS SEVERAL DISTURBANCES ROTATE
AROUND THE MAIN STORM SYSTEM AND TRACK ACROSS THE REGION. TIMING
AND TRACK ARE VERY UNCERTAIN SO BROAD BRUSHED THE AREA WITH MOSTLY
SLIGHT CHANCE POPS FRIDAY THROUGH MONDAY. COOLER WEATHER WILL ALSO
BE ENTRENCHED OVER THE AREA WITH HIGHS GENERALLY IN THE 50S AND
60S ACROSS THE PLAINS THROUGH THE WEEKEND.  MOZLEY

.AVIATION...

VFR CONDITIONS AT KALS THROUGH THE PERIOD WITH GUSTY WINDS
EXPECTED TO END AROUND 01Z. WINDS AGAIN BECOMING GUSTY AFTER 17Z
TUESDAY. A FEW SHOWERS ARE EXPECTED VICINITY KCOS AND KPUB THROUGH
18/03Z...THEN CEILINGS LOWERING TO JUST ABV VFR MINS BOTH
TERMINALS AFTER 06Z AND PERSISTING UNTIL AROUND 14Z. EASTERN
PLAINS OF COLORADO WILL HAVE AREAS OF MVFR OR IFR FROM 06Z THROUGH
14Z TUESDAY. -JKH-
