AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
335 AM MDT TUE JUN 14 2011

.SHORT TERM...HAVE BEEN DEALING WITH CONVECTION OVER THE PLAINS
OVERNIGHT AS WEAK UPPER LVL TROUGH AND ASSOCIATED QG ASCENT IN THE
MID LVLS IS NOW MOVING ACROSS.  AXIS OF THIS TROUGH SHOULD BE EAST
OF NERN CO BY LATE MORNING HOWEVER UNTIL IT PASSES THE THREAT OF
SHOWERS AND A FEW TSTMS WILL CONTINUE.  FOR THIS AFTN ALTHOUGH
SUBSIDENCE WILL DVLP BEHIND UPPER LEVEL TROUGH RATHER COOL MID LVL
TEMPS COMBINED WITH SOME LINGERING MOISTURE COULD ALLOW FOR SOME
ISOLD CONVECTION IN THE MTNS SOUTH OF I-70 AND OVER PORTIONS OF THE
PLAINS SO WILL KEEP IN LOW POPS.  AS FOR HIGHS WILL KEEP READINGS IN
THE UPPER 70S TO LOWER 80S ACROSS NERN CO.  FOR TONIGHT ANY
CONVECTION THAT DOES DVLP SHOULD QUICKLY END BY EARLY EVENING AS SEE
NOTHING TO KEEP IT GOING AFTER SUNSET.

.LONG TERM...AGREE WITH THE PREVIOUS FORECASTERS ASSESSMENT OF THE
UPCOMING WEEK OF WEATHER AND MADE ONLY MINOR ADJUSTMENTS TO THE
FORECAST PACKAGE.  THE GFS AND ECMWF HAVE NEARLY IDENTICAL SOLUTIONS
FOR THE UPPER AIR PATTERN OUT THROUGH ABOUT 120 HOURS AND THEN HAVE
SIMILAR IDEAS BEYOND THAT.  MODERATE WESTERLY FLOW ALOFT ON
WEDNESDAY IS FORECAST TO BECOME SOUTHWESTERLY THURSDAY AND THEN
REMAIN THAT WAY THROUGH EARLY NEXT WEEK.  UNCERTAINTIES STILL EXIST
IN FORECASTING WHICH DAYS WILL FEATURE AN EJECTING SHORTWAVE
EMBEDDED IN THE SOUTHWEST FLOW THAT WILL ORGANIZE AFTERNOON AND
EVENING CONVECTION.  IT IS ALSO HARD TO SAY THAT ANY PARTICULAR DAY
WILL BE COMPLETELY DRY.  LOW POPS WILL STAY IN THE FORECAST THROUGH
THE FORECAST PERIOD.  THE POSSIBLE EXCEPTION TO THIS IS THE WESTERLY
FLOW ON WEDNESDAY THAT DOES APPEAR THAT IT WILL BE DRIER THAN LATER
ON IN THE FORECAST PERIOD.

TEMPERATURES WILL CONTINUE RUNNING SLIGHTLY ABOVE NORMAL...BUT AM
STILL HESITANT TO FOLLOW THE EXTENDED MOS GUIDANCE WHICH IS
ADVERTISING HIGH TEMPERATURES IN THE LOWER 90S FROM THURSDAY THROUGH
SUNDAY.  THAT SCENARIO IS POSSIBLE UNDER THE SOUTHWESTERLY FLOW
ALOFT...BUT THE MEX GUIDANCE ALSO SEEMS TO HAVE HAD A WARM BIAS THIS
SPRING.  SO WILL STICK WITH THE MID AND UPPER 80S THAT BLENDS IN
WELL WITH NEIGHBORING OFFICE/S FORECASTS.

AT THE END OF THE FORECAST PERIOD...IT LOOKS LIKE COOLER
TEMPERATURES ARE IN STORE FOR MONDAY AS SOME COOLER AIR AT THE
SOUTHERN END OF A NORTHERN ROCKIES UPPER TROUGH MOVES ACROSS THE
STATE.  FOR THE TIME BEING COOLER AFTERNOON HIGHS AND ANOTHER ROUND
OF AFTERNOON THUNDERSTORMS ACROSS THE FORECAST AREA IS AN ADEQUATE
FORECAST.

&&

AVIATION...ANY TSTMS EARLY THIS MORNING SHOULD STAY EAST OF THE
AIRPORT.  FOR THIS AFTN WILL NOT MENTION ANY TSTMS IN THE TAF AS ANY
COVERGAGE SHOULD BE RATHER ISOLD.  WINDS THIS MORNING SHOULD BECOME
MORE WNW AFTER 15Z AND THEN MORE NWLY BY 18Z THRU THE AFTN.  BY
EVENING WILL HAVE WINDS TRENDING TO DRAINAGE.

&&

.HYDROLOGY...NO IMPACTS EXPECTED FOR THE BURN AREAS THIS AFTERNOON
OR EVENING.

TEMPERATURES WILL BE NEAR OR SLIGHTLY ABOVE NORMAL THROUGH NEXT
WEEKEND WITH THE WARMEST DAYS WEDNESDAY AND THURSDAY.  RIVER LEVELS
WILL NOT CHANGE MUCH FROM RECENT LEVELS.

A FLOOD WARNING CONTINUES FOR RIVERS IN JACKSON COUNTY. FLOOD
ADVISORIES CONTINUE FOR RIVERS IN GRAND COUNTY...THE LARAMIE RIVER
AND CACHE LA POUDRE RIVER AND TRIBUTARIES IN NORTHERN LARIMER COUNTY
AND THE CACHE LA POUDRE RIVER IN WESTERN WELD COUNTY.

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

THREAT OF SEVERE THUNDERSTORMS IS LOW.
