AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DENVER CO 210 PM MDT SAT JUL 5 2008 .SHORT TERM...THE UPPER RIDGE WILL GET SHIFTED TO THE SOUTH AND EAST AS A WEAK UPPER LEVEL DISTURBANCE RIDES OVER THE TOP OF IT. WEAK TSTMS HAVE DEVELOPEED ALONG THE FRONT RANGE WITH OUTFLOW BOUNDARIES ALREADY MOVING THROUGH THE METRO AREA. INTERACTIVE SOUDINGS KEEP CAPES IN THE 250-1000 J/KG RANGE WITH PW VALUES AROUND 0.80 INCHES. WL GO WITH PRIMARILY 20/30 PERCENT POPS TNGT. WEAK FORCING ASSOCIATED WITH A PASSING SHORT WAVE WILL MOVE ACROSS NRN CO OVERNIGHT. A FRONTAL BOUNDARY ASSOCIATED WITH THE TROF WILL MOVE INTO THE NORTHERN PLAINS SUNDAY MORNING. A LOW LEVEL THETE-E RIDGE WILL BACK INTO THE NERN PLAINS. INTERACTIVE SOUNDINGS SHOW CAPES RANGING FM 600-1100 J/KG ALG THE URBAN CORRIDOR AND PALMER DIVIDE...WITH CLOSE TO 3000 J/KG GENERATE BY THE NAM12 OVER THE NORTHEASTERN CORNER OF THE STATE. AS A RESULT...SOME SVR TSTMS WILL BE A POSSIBILITY SUNDAY AFTN. .LONG TERM...SHOWERS/THUNDERSTORMS ARE EXPECTED TO INCREASE SUNDAY EVENING AS SUBTROPICAL MOISTURE CONTINUES TO FEED UP FROM THE DESERT SOUTHWEST AHEAD OF A FAIRLY STRONG SHORTWAVE AT MID-LEVELS. EVENING STORMS ON THE PLAINS WILL BE CAPABLE OF LOCALLY HEAVY RAINFALL WITH PRECIPITABLE WATER VALUES WELL UP OVER AN INCH. DEEP CONVECTIVE FORMING ALONG A SFC BNDRY SWEEPING ACROSS NERN COLORADO IN THE EVENING MAY ALSO PRODUCE LARGE HAIL AND POSSIBLY A SMALL/BRIEF TORNADO OR TWO IN THE FAR NORTHEAST. DEPENDING ON HOW FAST THIS WAVE MOVES THROUGH THE AREA...MAY SEE A REPEAT ON MONDAY. HOWEVER...AT THE PRESENT TIME MODELS SHOW THE BEST VERTICAL MOTION AND MOISTURE ADVECTION OVER NERN COLORADO DURING THE MORNING HOURS...AND NOT DURING THE AFTERNOON WITH MAX HEATING. THEREFORE COULD SEE SOME SHOWERS AND POSSIBLY A T-STORM OR TWO BEFORE THE NOON HOUR AS WELL AS DURING THE AFTERNOON. ALTHOUGH BY THEN THE THETA-E RIDGE WILL MOST LIKELY BE EAST OF THE AREA...AND SO DO NOT SEE MUCH CHANCE FOR HEAVY RAINFALL. STORM CHANCES DECREASE EVEN FURTHER MONDAY NIGHT INTO TUESDAY AS DRIER MORE STABLE AIR MOVES IN BEHIND THE TROUGH. SHOULD SEE COOLER TEMPERATURES AS WELL MONDAY AND TUESDAY WITH DAYTIME READINGS NEAR TO SLIGHTLY BELOW NORMAL AS THE SFC-500MB FLOW GOES NLY. WEDNESDAY-SATURDAY...MODELS SHOW A GRADUAL REBOUND IN TEMPERATURES ON WEDNESDAY AS THE FLOW ALOFT BECOMES MORE ZONAL. EAST OF THE MTNS LOW-LEVEL FLOW BECOMES S-SELY WHICH THE GFS SHOWS ADVECTING INCREASING AMOUNTS OF MOISTURE UP INTO NERN COLORADO. BY WED EVENING...MODEL SHOWS A THETA-E RIDGE UP AGAINST THE SRN FOOTHILLS. THIS COULD CAUSE CONVECTION IN THIS AREA TO LINGER FOR MUCH OF THE NIGHT. BY THURSDAY AND FRIDAY...THE UPPER RIDGE BUILDING OUT WEST IS FCST TO SHIFT EAST OVER THE STATE BRINGING WITH IT ABNORMALLY WARM TEMPS. HUMIDITY FIELDS ALSO SHOW A STEADY INFLUX OF SUBTROPICAL MONSOONAL MOISTURE THRU THE PERIOD...WHICH SHOULD RETURN THE AREA TO A DAILY CYCLE OF AFTERNOON AND EVENING RAIN BARING THUNDERSTORMS. && .AVIATION...A FEW HIGH BASED STORMS COULD AFFECT THE AIRPORTS IN THE 21Z-01Z TIME PERIOD. OUTFLOW FROM THE STORMS MAY PRODUCE BRIEF WIND GUSTS IN THE 40-50 MPH RANGE. OTHERWISE EXPECT VFR CONDITIONS TODAY AND TONIGHT. && .BOU WATCHES/WARNINGS/ADVISORIES...NONE. && FMC/MRB
