NWS Denver/Boulder, CO wrote its last area forecast discussion before the first event at Jul 3, 2:25 AM MST, 10 hours 55 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DENVER/BOULDER CO 325 AM MDT SUN JUL 3 2005 .SHORT TERM...FOCUS IS ON CONVECTION AND POSSIBILITY OF SEVERE WEATHER TODAY. COLD FRONT ADVERTISED TO MOVE INTO THE AREA FOR THE PAST SEVERAL DAYS IS RATHER DIFFICULT TO PINPOINT AT THE CURRENT HOUR DUE TO INTERACTIONS WITH LARGE OUTFLOW BOUNDARY FROM THE MCS RACING ACROSS THE DAKOTAS. NONETHELESS...MAPS ANALYSIS SHOWS LARGE PRESSURE RISES EXTENDING FROM THE NEBRASKA PANHANDLE INTO SOUTH DAKOTA...AND ANOTHER ORGANIZING OVER SOUTHERN MONTANA. THIS SHOULD HELP BRING WINDS AROUND TO NORTHERLY AND EVENTUALLY NORTHEAST AS HIGH PRESSURE BUILDS OVER THE NORTHERN HIGH PLAINS THIS AFTERNOON. AS A RESULT...LOW LEVEL MOISTURE NOW SEEN OVER NORTHEAST WYOMING AND WESTERN SOUTH DAKOTA SHOULD BE ABLE TO MOVE INTO THE FORECAST AREA. THE UPPER 40S AND LOWER 50S DEWPOINTS WOULD BOOST CAPES INTO THE 1500-2000 J/KG RANGE PER INTERACTIVE SOUNDINGS. IN ADDITION...SATELLITE SHOWS A VIGOROUS SHORT WAVE ASSOCIATED WITH JET MAX MOVING ACROSS WYOMING AND NORTHERN UTAH. THIS FEATURE IS EXPECTED TO MOVE OVER THE FORECAST AREA LATE THIS MORNING AND AFTERNOON...AIDING AN EARLY START TO TODAYS CONVECTION. IN FACT... WE ALREADY HAVE SOME GOING EARLY THIS MORNING. THE JET CONTINUES TO PUSH EASTWARD TODAY...LEAVING NORTHEAST COLORADO IN FAVORABLE RIGHT REAR ENTRANCE REGION OF UPPER JET BY AFTERNOON. THE ASSOCIATED UPPER LEVEL DIVERGENCE WILL ACT TO ENHANCE STORM COVERAGE SO BOOSTED POPS INTO THE SCATTERED CATEGORY FOR THE MOUNTAINS AND MOST OF THE FRONT RANGE METRO AREAS. THE FAR NORTH COULD SEE LESSER CHANCES OF PRECIP LINGERING INTO THE LATE AFTERNOON AND EVENING HOURS DEPENDING ON EXACTLY HOW FAST THE FORCING ASSOCIATED WITH THE UPPER JET MOVES OUT. AT THIS TIME...THE THREAT OF SEVERE STORMS LOOKS FAIRLY HIGH GIVEN CAPES OF 1500-2000 J/KG AND 0-6KM SHEAR OF 20-25 M/S. WOULD NOT BE SURPRISED TO GENERATE A FEW SUPERCELLS CAPABLE OF PRODUCING LARGE HAIL. ANY TORNADO THREAT WOULD BE MINIMIZED BY LACK OF LOW LEVEL SHEAR. .LONG TERM...MONDAY...THE ERN PLAINS WL BE IN A POST-FNTL ENVIRONMENT AS PW VALUES WL RMN ARND THREE QUARTERS OF AN INCH. MDLS INDG LOW LVL FLOW WL TURN SELY DURING THE AFTN. THUS WITH THE WLY ALF AND SELY NR THE SFC...QUITE A BIT OF SHEAR WL BE AVBL FOR TSTMS TO WORK WITH. USING MAX TEMPS IN THE MID 80S YIELDS NRLY 2500 J/KG CAPE NUMBERS. WL HAV TO KEEP A WATCHFUL EYE ON THE POTENTIAL FOR SVR WX POSSIBILITY DURING THE 4TH OF JULY FESTIVITIES. WL ADJUST POPS UPWARD INTO THE SCT CATEGORY FOR THE ENTIRE PLAINS AS TSTMS SEEM LIKE A GOOD BET. AFTER MONDAY...WK LONGWAVE RDG WL BLD OVR WRN CO/ERN UT. THIS WL ALLOW WLY FLOW ALF TO CONTINUE ACRS THE FCST AREA. A COUPLE OF DECENT SHORTWAVES WL RIP PAST THE AREA TUESDAY EVENING AND AGAIN THURSDAY AFTERNOON. THIS WL KEEP THE FCST AREA IN LINE FOR AFTN/EVENING TSTMS...ALTHO AT THIS TIME IT IS DIFFICULT TO TIME THESE FEATURES. WL KEEP ISOLD CONVECTION IN THE FCST FOR NOW WITH NR NRML TEMPS AS UPR RDG SHOWS LTL SIGNS OF RELINQUISHING ITS GRIP ON THE WEST. && .BOU...NONE. && BARJENBRUCH/046
