VALID 12Z TUE JUL 29 2014 - 12Z THU JUL 31 2014

...HEAVY RAINS AND FLASH FLOODING EXPECTED ACROSS EASTERN COLORADO
AND MUCH OF OKLAHOMA...

...BELOW NORMAL TEMPERATURES WILL CONTINUE BENEATH A BROAD TROUGH
CARVED OUT OVER THE EASTERN HALF OF THE NATION...


WIDESPREAD SHOWERS WILL CONTINUE ACROSS THE CENTRAL GREAT BASIN
AND CENTRAL/SOUTHERN ROCKIES THE NEXT FEW DAYS.  MUCH OF THE
ACTIVITY SHOULD BE SCATTERED IN NATURE...BUT ANOMALOUS MOISTURE
TRAPPED OVER THE REGION COULD LEAD TO LOCALLY MODERATE TO HEAVY
RAINS.  SLIGHTLY FARTHER EAST...ENERGY DIVING SOUTHEASTWARD
THROUGH THE CENTRAL ROCKIES WILL HELP ORGANIZE AN AREA OF HEAVY
RAINS AND THUNDERSTORMS TO THE NORTH OF A SURFACE LOW AND FRONTAL
BOUNDARY STRENGTHENING OVER THE COLORADO FRONT RANGE TUESDAY
AFTERNOON.  ALTHOUGH THE DROUGHT STRICKEN AREAS COULD USE THE
PRECIPITATION...LOCALLY HEAVY DOWNPOURS COULD LEAD TO FLASH
FLOODING.  THE HEAVY RAINS AND THREAT FOR FLASH FLOODING WILL
SPREAD ACROSS MUCH OF OKLAHOMA AS THE ENERGY ALOFT CONTINUES ITS
SOUTHEASTWARD TREK TUESDAY NIGHT INTO WEDNESDAY.

BELOW NORMAL TEMPERATURES WILL CONTINUE BENEATH A BROAD AND
ANOMALOUS TROUGH CARVED OUT OVER THE EASTERN HALF OF THE NATION.
MUCH OF THE EAST WILL STAY PRECIPITATION FREE; HOWEVER...A COLD
FRONT DROPPING DOWN FROM CANADA WILL TRIGGER SCATTERED SHOWERS AND
THUNDERSTORMS ACROSS THE GREAT LAKES REGION.  ALSO...SCATTERED
CONVECTION WILL CONTINUE OVER FLORIDA AND THE GULF COAST THE NEXT
FEW DAYS...TO THE SOUTH OF A FRONTAL BOUNDARY PLUNGED ACROSS THE
SOUTHERN TIER OF THE COUNTRY.

WHILE THE EAST REMAINS RELATIVELY COOL...AN AMPLIFIED UPPER RIDGE
WILL KEEP TEMPERATURES ABOVE NORMAL OVER THE NORTHERN ROCKIES AND
INTERMOUNTAIN WEST.  HEAT ADVISORIES HAVE BEEN ISSUED FOR PORTIONS
OF WASHINGTON STATE...WHERE DAYTIME TEMPERATURES WILL SOAR INTO
TRIPLE DIGITS AND OVERNIGHT LOWS WILL BARELY DROP OUT OF THE
SEVENTIES.

500 PM EDT MON JUL 28 2014

VALID 00Z TUE JUL 29 2014 - 00Z THU JUL 31 2014

...COOLER THAN NORMAL JULY WEATHER CONTINUES FOR MUCH OF THE
EASTERN HALF OF THE COUNTRY...

...SUMMER-TIME SHOWERS AND THUNDERSTORMS LINGER IN FLORIDA AND
NEAR THE GULF COAST...

...MONSOONAL MOISTURE WILL CONTINUE TO DELIVER SHOWERS AND
THUNDERSTORMS  ACROSS MUCH OF THE INTERIOR WESTERN U.S...

DURING THE SHORT-RANGE FORECAST PERIOD, AN UNUSUALLY BROAD AND
DEEP UPPER-LEVEL TROUGH IS EXPECTED TO REMAIN THE DOMINANT FEATURE
OVER THE EASTERN HALF OF THE COUNTRY.  THIS FEATURE WILL BRING A
NICE STRETCH OF UNUSUALLY COOL AND PLEASANT JULY WEATHER INTO THE
REGION THROUGH MID-WEEK.  THE COOLEST AIR WILL BE FOUND IN THE
UPPER GREAT LAKES WHERE TEMPERATURES ARE EXPECTED TO DROP TO NEAR
50 DEGREES BY DAYBREAK.  NEVERTHELESS, A NEW COLD FRONT WILL BRING
A REINFORCING SHOT OF COOLER AIR FROM CANADA BY WEDNESDAY,
TOGETHER WITH SCATTERED SHOWERS AND THUNDERSTORMS.  MEANWHILE, THE
TYPICAL SUMMER-TIME HEAT AND HUMIDITY WILL BE SHOVED WELL TO THE
SOUTH ALONG THE GULF COAST AND INTO FLORIDA WITH SHOWERS AND
THUNDERSTORMS LINGERING THROUGH MID-WEEK.

OUT WEST, WITH AN UPPER-LEVEL RIDGE REMAINING IN PLACE, MONSOONAL
TYPE SHOWERS AND THUNDERSTORMS ARE EXPECTED TO BE THE RULE OVER
THE INTERIOR MOUNTAINS THROUGH MID-WEEK, WHICH WILL BE ENHANCED BY
HEATING DURING LATE AFTERNOON AND EARLY EVENING HOURS.  AN
UPPER-LEVEL IMPULSE OVER THE CENTRAL/SOUTHERN ROCKIES IS FORECAST
TO TRIGGER ADDITIONAL SHOWERS AND THUNDERSTORMS AND IS EXPECTED TO
PUSH THEM OUT INTO THE CENTRAL PLAINS BY EARLY ON WEDNESDAY.  THIS
DISTURBANCE WILL ALSO INITIATE THE SOUTHWARD PROGRESSION OF A COLD
FRONT THROUGH THE SOUTHERN ROCKIES AND SOUTHERN PLAINS DURING THE
DAY ON WEDNESDAY.

ELSEWHERE, WEATHER SHOULD REMAIN DRY ALONG THE WEST COAST THROUGH
MID-WEEK.
