AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
322 AM MDT MON MAY 24 2010

.SHORT TERM...UPPER LEVEL LOW IS CURRENTLY SPINNING OVER UTAH AND
WILL QUICKLY MOVE TO THE NORTHEAST TODAY. BY LATE AFTERNOON...IT
WILL BE OVER CENTRAL WYOMING AND BY 12Z TUESDAY IT WILL NEARLY BE IN
CANADA. AS IT PASSES TO THE NORTHWEST OF THE FORECAST AREA...IT WILL
BRING A STRONG SOUTHERLY FLOW THIS MORNING AND THEN A STRONG WEST TO
SOUTHWEST FLOW THIS AFTERNOON. WINDS WILL AGAIN BE THE BIGGEST ISSUE
TODAY. STRONG SOUTHERLY WINDS WILL PREVAIL THIS MORNING AND TURN TO
THE SOUTHWEST BY NOON AND THEN TO THE WEST BY 00Z. THE SOUTHERLY
WINDS HAVE BROUGHT MOIST AIR BACK INTO THE AREA WITH DEW POINTS IN
THE 50S. HOWEVER...THE MOISTURE IS SHALLOW AND WILL QUICKLY BE SWEPT
OUT BY THE DRIER SOUTHWEST WINDS LATER THIS MORNING. WILL SEE VERY
GOOD MIXING TODAY DUE TO COLD AIR ADVECTION...THUS IT WILL BE EASY
TO MIX THE STRONGER WINDS ALOFT DOWN. WINDS SPEEDS LOOK TO BE
SUSTAINED IN THE 20 TO 30 KNOTS RANGE WITH GUSTS UP TO 50 KNOTS.
BECAUSE OF THE COLD AIR ADVECTION...HIGH TEMPERATURES WILL BE COOLER
THAN YESTERDAY. THE ONLY EXCEPTION WILL BE THE FAR EASTERN PLAINS
WHERE IT WILL TAKE THE COOLER AIR LONGER TO REACH AND HIGHS WILL BE
IN THE UPPER 70S.

PRECIPITATION CHANCES WILL AGAIN BE ON THE LOW SIDE. THE BEST CHANCE
FOR SHOWERS AND POSSIBLY A FEW THUNDERSTORMS WILL BE OVER THE NORTH
CENTRAL MOUNTAINS. THIS IS WHERE LIFT WILL BE THE GREATEST AS THE
UPPER LEVEL LOW PASSES TO THE NORTH. THE NORTHEAST CORNER OF
COLORADO MAY SEE A COUPLE OF THUNDERSTORMS THIS AFTERNOON. MOISTURE
SHOULD HANG ON UNTIL EARLY AFTERNOON AND CAPES WILL CLIMB TO AROUND
1000 J/KG. BIGGEST QUESTION CONCERNING THE CONVECTION IS CAN IT
BREAK THE CAP BEFORE THE DRY AIR MOVES IN.

THE WINDY CONDITIONS WILL QUICKLY TAPER OFF EARLY THIS EVENING.
AIRMASS WILL BE DRY BEHIND THE SYSTEM AND EXPECT MOSTLY CLEAR SKIES
FOR TONIGHT. LOWS WILL BE ON THE COOL SIDE DUE TO THE DRY AIRMASS.
MOST LOCATIONS ACROSS NORTHEAST COLORADO WILL BE IN THE UPPER 30S TO
LOWER 40S.

.LONG TERM...ONLY MINOR ADJUSTMENTS PLANNED.  NOT MUCH CHANGE IN THE
OVERALL PATTERN FM YESTERDAY.  COLORADO WILL BE UNDER A PERSISTENT
SOUTHWESTERLY FLOW ALOFT...WITH A TROF OVER THE PACIFIC NORTHWEST
AND A BUILDING RIDGE OVER THE CENTRAL PLAINS.  THE FLOW ALOFT WILL
BE WEAKENING SOMEWHAT OVER COLORADO ON TUESDAY WITH A SHORT WAVE
RIDGE OVER THE CWFA.  DRIEST AMS WILL BE OVER THE MTNS.  SELY SFC
WINDS OVER THE PLAINS WILL USHER IN INCRG BOUNDARY LYR MSTR LATE
TUESDAY AFTN/EVNG.  BEST CHC OF TSTMS TUESDAY AFTN WILL BE IN THE
VICNITY OF THE PALMER DIVIDE.  ONLY CHANGE TO TUESDAY WAS TO HOLD
OFF TSTMS FOR ZONES 44..45 AND 49 UNTIL TUESDAY NIGHT.  INTERACTIVE
SOUNDINGS KEEPS THE LOWER LEVELS FAIRLY DRY THROUGH THE DAY ALTHOUGH
THEY WILL BE MODERATING UPWARDS TOWARDS 00Z WEDNESDAY...SO THE
BEST CHC OF TSTMS WILL BE TUESDAY EVENING.  ENOUGH OF AN INCREASE IN
BOUNDARY LYR MSTR OVERNIGHT TO ADD THE POSSIBILITY OF PATCHY FOG AS
WELL FOR LATE TUESDAY NIGHT AND WEDNESDAY MORNING.  FOR THE REST OF
THE PERIOD...TEMPERATURES WILL CONTINUE TO INCREASE SLIGHTLY EACH
DAY AS THE RIDGE BUILDS UP OVER THE CENTRAL PLAINS.  NO SIGNIFICANT
SYNOPTIC SCALE FEATURES MOVING OVER THE AREA THROUGH AT LEAST
FRIDAY...SO THE PATTERN WILL BE RELATIVELY BENIGN.  THERE WILL STILL
BE ENUF MSTR AROUND TO INCLUDE THE SLGT CHC OF TSTMS EACH
AFTN/EVNG.  THIS ALREADY REFLECTED IN THE GRIDS TO NO CHANGES NEEDED
FOR THE LATER PERIODS AT THIS TIME.

&&

.AVIATION...THERE WILL BE A SLIGHT CHANCE FOR LOW CLOUDS THROUGH
14Z. IF ANY LOW CLOUDS DEVELOP THEY SHOULD BE IN THE 1500 TO 3000
FOOT RANGE. THE BIGGEST ISSUE TODAY WILL BE THE STRONG WINDS. STRONG
SOUTHERLY WINDS EARLY THIS MORNING WILL TURN SOUTHWEST BY MID
MORNING AND THEN TO THE WEST BY LATE AFTERNOON AS A LOW PRESSURE
SYSTEM PASSES TO THE NORTH. SUSTAINED WINDS WILL BE 20 TO 30 KNOTS
AND GUSTS COULD REACH AS HIGH AS 45 KNOTS. AIRMASS WILL BE UNSTABLE
THIS AFTERNOON...BUT BECAUSE OF THE DRY AIR MOVING IN FROM THE WEST
NO SHOWERS OR THUNDERSTORMS ARE EXPECTED.

&&

.BOU WATCHES/WARNINGS/ADVISORIES...NONE.
