AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
300 PM MDT SUN JUL 4 2010

.SHORT TERM...THE PLAINS ARE BEGINNING TO DESTABILIZE AS MORE AND
MORE CELLS FIRING OFF THE FOOTHILLS ARE ABLE TO MOVE FARTHER EAST.
HOWEVER...LOOKING AT THE VERTICAL DEVELOPMENT OF THE CU OUTSIDE AND
AT ACARS SOUNDINGS...THERE IS QUITE A STRONG CAP THAT REMAINS. AS
THE UPPER TROUGH CURRENTLY OVER UTAH MOVES CLOSER AND PROVIDES AN
INCREASE IN QG LIFT AND THE OVERCAST SKIES NOW CLEARING PROVIDING
HEATING FROM BELOW...SHOULD HELP BREAKDOWN THE CAP MID TO LATE
AFTERNOON. CURRENTLY A FEW STORMS OVER THE PALMER DIVIDE HAVE BEEN
ABLE TO SUSTAIN FOR A BIT AS THEY ARE OVER HIGHER TERRAIN AND THE
CAP IS WEAKENING EASIER THERE. A TORNADO HAS BEEN ISSUED FOR THE
NORTHERN COLORADO BORDER AS STORMS IN WYOMING HAVE BEEN PRODUCING
SEVERAL TORNADOES. BELIEVE IT WILL STILL BE A FEW MORE HOURS BEFORE
WE SEE ANYTHING REALLY GET GOING STRONG IN OUR FORECAST AREA. STORMS
OVER THE HIGHER TERRAIN WILL HELP WEAKEN THE CAPPED MOIST
ENVIRONMENT ON THE PLAINS IN THE LATE AFTERNOON AND EVENING. WINDS
ALOFT WILL HELP THE STORMS MOVE ABOUT 10 TO 15 KNOTS SO MAJOR
FLOODING IS NOT EXPECTED. HOWEVER WITH SUCH A MOIST ENVIRONMENT
STORMS WILL HAVE THE POTENTIAL THIS EVENING AND TONIGHT TO PRODUCE
HEAVY RAIN IN EXCESS OF 2 INCHES AN HOUR OUT OF THE STRONGER STORMS.
AS THESE STORMS BECOME MORE NUMEROUS...SMALL STREAMS AND STREETS MAY
HAVE SMALL FLOODING ISSUES. MIXED LAYER CAPES OF AROUND 1000 J/KG
AND ENOUGH SHEAR WITH COOLING ALOFT FROM THE PASSING UPPER TROUGH
LATER TONIGHT WILL ALLOW LARGE HAIL AND A POSSIBLE TORNADO BE THE
MAIN THREATS.  EXTENDED HIGHER POPS THIS EVENING AND SLOWED THE
DECREASE EVEN FURTHER AS THE UPPER LOW WILL NOT PASS OVER
NORTHEASTERN COLORADO UNTIL EARLY MONDAY MORNING. COULD SEE SHOWERS
AND A SLIGHT CHANCE OF THUNDERSTORMS PAST MIDNIGHT INTO THE MORNING
HOURS OVER THE EASTERN PLAINS.
TOMORROW WILL BE A MUCH QUIETER DAY AS SUBSIDENCE ON THE BACKSIDE OF
THE TROUGH KEEPS POPS TO A MINIMUM. ONLY THE MOUNTAINS HAVE A SLIGHT
CHANCE OF A FEW LIGHT RAIN SHOWERS AS DRIER AIR MOVES IN.
TEMPERATURES WILL BE SIMILAR TO TODAY WITH SLIGHT WARMING OVER THE
PLAINS BY A FEW DEGREES. WINDS WILL BE LIGHT SO NO FIRE WEATHER
CONCERNS.

.LONG TERM...THE NEXT IN A SERIES OF ACTIVE SHORTWAVE IMPULSES SWING
OUT OF THE PACIFIC NORTHWEST AND ACROSS NORTHERN COLORADO TUESDAY
AFTERNOON INTO WEDNESDAY...ONCE AGAIN IMPACTING AREAS MAINLY EAST OF
THE FRONT RANGE. A SFC COLD FRONT ORGANIZING OUT AHEAD OF THE MAIN
TROUGH IS PROGGED BY THE NAM TO GFS TO SLIDE SOUTHWARD OUT OF SRN
WYOMING/WRN NEBRASKA AND ACROSS NERN COLORADO BY LATE TUESDAY
MORNING. DURING THE AFTERNOON MODEL X-SECTIONS AND SOUNDINGS SHOW
MOIST E-NELY UPSLOPE FLOW DEEPENING ON THE PLAINS WITH PRECIPITABLE
WATER VALUES RISING FM ABOUT A HALF INCH IN THE MORNING TO AROUND AN
INCH BY 00Z/WED...TO AROUND 1.25 INCH DURING THE EVENING. MEANWHILE
AT THE SAME TIME SLY MID-LEVEL FLOW IN ADVANCE OF THE TROUGH
TRANSPORTS A NARROW PLUME OF SUBTROPICAL MOISTURE UP FM NEW MEXICO
AND OVER ERN PORTIONS OF COLORADO FURTHER MOISTENING THE COLUMN OVER
THE AREA. BY 00Z/WED NAM INDICATES SFC BASED CAPES OVER 2000 J/KG IN
THE VICINITY OF WHAT APPEARS TO BE A STALLED SFC FRONTAL BNDRY
SITTING ALONG THE SPINE OF THE PALMER DIVIDE. QPF FIELDS OFF THE NAM
AND GFS INDICATE A BULLS EYE OF 2-4 INCH RAINFALL 3-HR TOTALS
TUESDAY EVENING WITHIN A ZONE OF STG LOW-LEVEL CONVERGENCE AND SHEAR
ALONG THE FRONT...CENTERED AROUND THE LIMON AREA. PAST COUPLE MODEL
RUNS HAVE INDICATED A SIMILAR QPF PATTERN. MINOR IMPULSES
TRANSLATING ALONG THE BOTTOM OF THE MAIN TROUGH ARE LIKELY TO
PRODUCE CONVECTION IN OTHER PARTS OF THE CWFA THROUGH THE NIGHT.
AFTER MIDNIGHT WITH ALL OF THE MOISTURE AND OUTFLOW BNDRYS FLOATING
AROUND PRETTY GOOD BET WE/LL SEE SOME LOCALLY DENSE FOG ON THE
PLAINS. WHILE ALL THIS IS GOING ON...MTN AREAS INCLUDING THE WRN
VALLEYS SHOULD ESCAPE WITH LITTLE MORE THAN ISOLATED TO WIDELY
SCATTERED AFTN AND EVE -SHRA/-TSTMS ALONG WITH NOT MUCH COOLING.

BY WEDNESDAY...AMBIENT HIGH PLAINS AIRMASS REMAINS RELATIVELY COOL
AND MOIST WITH GENERAL TROUGHING OVER THE REGION AND WEAK LOW-LEVEL
UPSLOPE FLOW EAST OF THE MTNS. LOOKING FOR MAX TEMPS ON THE PLAINS
TO BE AS MUCH AS 12-15F BELOW AVERAGE. AVG HIGH AT DENVER AT THIS
TIME IS 87F. ATMOSPHERE LOOKS A BIT MORE STABLE OUT ACROSS THE
PLAINS...SO RAIN CHANCES EXPECTED TO DROP OFF OUT THERE. CLOSER IN
TO THE FRONT RANGE MONSOONAL MOISTURE STILL IN PLACE AND WITH
DIABATIC HEATING SHOULD SEE RE-DEVELOPMENT OF SHWRS AND STORMS BY
AFTERNOON. LIGHTER FLOW MAY PRODUCE A FEW HVY RAIN MAKERS IN AND
NEAR THE FTHLS LATE IN THE DAY.

BY THURSDAY...SHORTWAVE TROUGH MOVES OUT MAKING WAY FOR AN UPPER
RIDGE TO BUILD IN THE FM 4-CORNERS REGION. WARMING BEGINS ALOFT
INITIALLY EVENTUALLY MIXING DOWN TO THE GROUND THRU THE DAY. SHOULD
SEE AFTERNOON TEMPS RETURNING TO THE LOWER 80S ON THE PLAINS.

FRIDAY AND BEYOND...MEDIUM RANGE MODELS SHOW RESUMPTION OF THE
MONSOON MOISTURE PLUME COMING UP FM NRN MEXICO BENEATH THE UPPER
RIDGE SITTING OVER THE REGION. AS A RESULT SHOULD SEE AN INCREASED
CHANCE FOR SOAKING RAINFALL FROM WARM CORE CONVECTION. LOOKING FOR
TEMPS TO BE NEAR OR SLIGHTLY ABOVE NORMAL DURING THE PERIOD.

&&

.AVIATION...SHOWERS AND THUNDERSTORMS ARE EXPECTED TO INCREASE IN
THE LATE AFTERNOON AND EVENING AND INSTRUMENT APPROACHES TO KDEN
WILL LIKELY BE NEEDED. THERE MAY BE SOME LOCALIZED IFR
CEILINGS/VISIBILITIES IN THE RAIN THIS EVENING. SHOWERS WILL
DIMINISH AFTER MIDNIGHT BUT LOW CEILINGS WILL LIKELY PERSIST INTO
TUESDAY MORNING. EXPECT CEILINGS TO IMPROVE AFTER 15Z WITH VFR
CONDITIONS PREVAILING THROUGH MONDAY.

.BOU WATCHES/WARNINGS/ADVISORIES...TORNADO WATCH FOR
