UPDATE...
UPDATED THE FORECAST FOR SEVERE THUNDERSTORM WATCH 636. NO OTHER
MAJOR CHANGES TO THE FORECAST.
PREV DISCUSSION... /ISSUED 257 PM CDT WED JUL 29 2009/
DISCUSSION...
COLD FRONT NUDGING INTO SOUTHEASTERN COLORADO SHOULD ENTER THE
PANHANDLE REGION AROUND MIDNIGHT. AHEAD OF THIS FRONT...CONVECTION
MOVING OFF THE HIGHER TERRAIN OF NEW MEXICO AND COLORADO...WILL
PROPAGATE INTO THE PANHANDLE REGION. LIKE YESTERDAY...MODEST WIND SHEAR
VALUES COULD RESULT IN SOME SEVERE STORMS. UNLIKE YESTERDAY...LOW
AND MID CLOUDS ACROSS MUCH OF THE REGION HAVE MINIMIZED THE AMOUNT OF
DIURNAL HEATING...AND THEREFORE DO NOT EXPECT MUCH CONVECTIVE
INITIATION IN THE PANHANDLES.
MODELS HAVE BEEN TRENDING DRIER FROM THURSDAY THROUGH FRIDAY NIGHT.
THIS IS LIKELY DUE TO THE MORE STABLE AND DRIER AIR MASS BEHIND THE
FRONT. HOWEVER...WITH CONTINUED UPPER LEVEL SHORTWAVE TROUGHS
TRAVERSING THE HIGH PLAINS AND CONSIDERING THE RECENT TRENDS...AM
HESITANT TO REMOVE PRECIPITATION FOR ANY PERIOD. A PACIFIC COLD
FRONT SHOULD APPROACH THE REGION SATURDAY...THOUGH MODELS DISAGREE ON
IF IT WILL STALL NORTH OF THE REGION OR IN THE PANHANDLE REGION.
REGARDLESS OF THE SOLUTION...CHANCES FOR PRECIPITATION INCREASE
ESPECIALLY SATURDAY NIGHT THROUGH SUNDAY.
IN THE EXTENDED...GFS CONTINUES TO SHOW THE UPPER LEVEL RIDGE
BUILDING TO THE SOUTHEAST...CLOSER TO THE SOUTHERN HIGH PLAINS. THE
ECMWF...THOUGH IT CONTINUES TO FAVOR NORTHWEST FLOW IS SHOWING THE
RIDGE AXIS A LITTLE FURTHER TO THE EAST THAN PREVIOUS RUNS.
CONSIDERING THIS TREND...HAVE KEPT THE FORECAST DRY AFTER MONDAY
NIGHT.
FIRE WEATHER...
RECENT PRECIPITATION AND RELATIVELY HIGH ATMOSPHERIC MOISTURE WILL
KEEP FIRE WEATHER CONCERNS LOW OVER THE NEXT SEVERAL DAYS.
HYDROLOGY...
FLASH FLOODING OCCURRED IN PALO DURO CANYON AND MANY LOCATIONS HAD
WELL OVER AN INCH YESTERDAY...LEAVING MUCH OF THE REGION WITH
SATURATED GROUND. ATMOSPHERIC MOISTURE...IN TERMS OF PRECIPITABLE
WATER...REMAINS WELL ABOVE SEASONABLE NORMAL. IN ADDITION...AN
APPROACHING COLD FRONT WILL PROVIDE AMPLE LIFT AND A FOCUS FOR
THUNDERSTORM DEVELOPMENT. ERGO...WIDESPREAD ADDITIONAL RAIN
BETWEEN A QUARTER AND A HALF AN INCH WILL BE POSSIBLE TONIGHT.
ISOLATED RAIN TOTALS ABOVE 1 INCH WILL ALSO BE POSSIBLE. WITH THE
SATURATED GROUND...ANY ADDITIONAL RAIN WILL QUICKLY BECOME RUNOFF
AND COULD LEAD TO HIGHER THAN NORMAL RISES IN SMALL STREAMS AND URBAN
AREAS. THEREFORE WILL CONTINUE THE FLASH FLOOD WATCH ACROSS THE
REGION THROUGH 18Z TOMORROW. THE FLASH FLOOD THREAT SHOULD BEGIN TO
DIMINISH TOMORROW AS THE AIR BEHIND THE COLD FRONT WILL BE
RELATIVELY STABLE LEADING TO LESS COVERAGE OF THUNDERSTORMS.
