wow, it looks like it's coming off of a front... Stupid High is still sitting over parts of the SE...wish it would end, these 100 degree temps are brutal as my kinds want to play outside and i won't let them because it's just too hot. here's what the NWS has to say... SHORT RANGE FORECAST DISCUSSION NWS HYDROMETEOROLOGICAL PREDICTION CENTER CAMP SPRINGS MD 445 PM EDT SUN JUL 08 2012 VALID 00Z MON JUL 09 2012 - 00Z WED JUL 11 2012 ...THE BLAZING TEMPERATURES WHICH HAD PLAGUED A REGION FROM THE MIDDLE MISSISSIPPI VALLEY EASTWARD TO THE MID-ATLANTIC SHOULD FINALLY COME TO AN END ON MONDAY... ...EPISODES OF SEVERE WEATHER ARE POSSIBLE ALONG THE FRONTAL BOUNDARY AS IT SINKS SOUTHWARD FROM THE MID-ATLANTIC/LOWER OHIO VALLEY DOWN TO THE CAROLINAS... ...AREAS OF EASTERN COLORADO MAY SEE A THREAT FOR EXCESSIVE RAINFALL THROUGH MONDAY MORNING... AN UPPER RIDGE WHICH HAD BEEN CENTERED ACROSS THE MIDDLE MISSISSIPPI VALLEY AND INTO THE TENNESSEE/OHIO RIVER VALLEYS WILL CONTINUE TO WEAKEN AS A NORTHERN STREAM TROUGH AMPLIFIES ACROSS EASTERN CANADA. THE PRIMARY EFFECT OF THIS SYNOPTIC REGIME IS TO BRING A FRONTAL BOUNDARY THROUGH MUCH OF THE AREAS WHICH HAD BEEN EXPERIENCING ABOVE 100 DEGREE HEAT WITH ACCOMPANYING HUMIDITY. THIS WILL ULTIMATELY BRING RELIEF TO LOCATIONS SUCH AS SAINT LOUIS MO...CHICAGO IL...INDIANAPOLIS IN...WASHINGTON D.C...AMONG OTHERS. HIGH TEMPERATURES EARLY NEXT WEEK ARE GENERALLY EXPECTED TO STAY AT 90 DEGREES OR BELOW WHICH WILL BE QUITE THE CHANGE FROM THE START OF JULY. USHERING IN THIS COOLER AIR MASS WILL BE THE AFOREMENTIONED COLD FRONT WHICH WILL FEATURE NUMEROUS SHOWERS AND THUNDERSTORMS ALONG IT. GIVEN THE EXTREME HEAT AND HUMIDITY SOUTH OF THE BOUNDARY...ABUNDANT INSTABILITY WILL BE PRESENT WHICH COULD PRODUCE REGIONS OF SEVERE WEATHER. THE STORM PREDICTION CENTER SUGGESTS THE BIGGEST THREAT WILL BE DAMAGING WINDS WITH ISOLATED REPORTS OF LARGE HAIL ALSO POSSIBLE. SUCH STORMS SHOULD CONTINUE TO CONGREGATE ALONG THE BOUNDARY SLOWING DROPPING SOUTHWARD WHERE IT WILL EVENTUALLY ATTAIN A QUASI-STATIONARY STATE. THIS WAVY FRONTAL SYSTEM IS EXPECTED TO LINGER FROM THE UPPER CAROLINAS BACK THROUGH THE LOWER TENNESSEE VALLEY AND INTO THE ARKLATEX. TO THE SOUTH OF THIS BOUNDARY...DAILY THREATS FOR THUNDERSTORMS WILL REMAIN POSSIBLE ACROSS THE MOIST AND UNSTABLE AIR MASS OVER THE SOUTHERN U.S. ADDITIONAL FOCUS FOR HEAVIER POCKETS OF STORMS SHOULD BE IN PLACE AS WEAK MID-LEVEL IMPULSES MEANDER OVER THE LOWER MISSISSIPPI VALLEY. OVER THE SOUTHWESTERN SECTOR OF THE U.S...AN ACTIVE MONSOONAL FLOW FROM THE GULF OF MEXICO AND BAJA WILL TRANSPORT ABUNDANT MOISTURE NORTHWARD INTO THE DESERT SOUTHWEST AND FOUR CORNERS REGION. THE ENHANCED LOW TO MID-LEVEL MOISTURE IN PLACE IN COMBINATION WITH SUFFICIENT AFTERNOON HEATING SHOULD LEAD TO WIDESPREAD MONSOONALLY-DRIVEN THUNDERSTORMS EACH DAY. PARTICULAR FOCUS SHOULD TAKE PLACE ALONG THE LOCAL TOPOGRAPHY AS THEY WILL BE AIDED BY OROGRAPHIC EFFECTS. FURTHER TO THE NORTH ACROSS THE FRONT RANGE OF THE CENTRAL ROCKIES...MID-LEVEL DISTURBANCES MEANDERING WITHIN THE AXIS OF WEAKER FLOW ALOFT SHOULD HELP FOCUS AN AXIS OF HEAVIER PRECIPITATION IN THE VICINITY OF EASTERN COLORADO. GIVEN RECENT MODERATE TO HEAVY RAINFALL OVER THE REGION...THE HPC EXCESSIVE RAINFALL FORECAST SUGGESTS A THREAT FOR FLASH FLOODING WILL BE POSSIBLE OVER THIS AREA THROUGH MONDAY MORNING.
