VALID 12Z MON JUL 25 2016 - 12Z WED JUL 27 2016

...STRONG TO SEVERE THUNDERSTORMS POSSIBLE ACROSS PORTIONS OF THE
MID-ATLANTIC STATES...

...HEAT ADVISORIES REMAIN IN EFFECT THROUGH MONDAY FOR PORTIONS OF
THE EASTERN U.S...

A COLD FRONT WILL PRODUCE SHOWERS AND THUNDERSTORMS FROM THE
CENTRAL/SOUTHERN PLAINS AND OHIO VALLEY TO THE MID-ATLANTIC AND
NORTHEAST TODAY, BRINGING THE THREAT OF LOCALLY HEAVY RAINFALL.
SOME THUNDERSTORMS COULD BE SEVERE ACROSS PORTIONS OF THE
MID-ATLANTIC REGION. PLEASE REFER TO PRODUCTS ISSUED BY THE STORM
PREDICTION CENTER FOR FURTHER DETAILS ON THE SEVERE WEATHER
THREAT. THE COLD FRONT WILL MOVE OFFSHORE OF THE NORTHEAST BY
TUESDAY, BRINGING AN END TO MOST PRECIPITATION OVER THAT AREA. THE
FRONT WILL LINGER FROM THE SOUTHERN PLAINS AND MID-MISSISSIPPI
VALLEY TO THE MID-ATLANTIC AS A STATIONARY FRONT AND EVENTUALLY A
WARM FRONT, KEEPING SCATTERED SHOWERS AND STORMS A POSSIBILITY
INTO TUESDAY AND WEDNESDAY. FARTHER NORTH, ANOTHER COLD FRONT WILL
MOVE INTO THE NORTHERN PLAINS ON TUESDAY, BRINGING SCATTERED
SHOWERS AND THUNDERSTORMS FROM THE NORTHERN PLAINS TO THE UPPER
MIDWEST THROUGH WEDNESDAY. SCATTERED AFTERNOON AND EVENING SHOWERS
AND THUNDERSTORMS WILL ALSO CONTINUE THROUGH MID-WEEK ACROSS THE
GULF COAST AND SOUTHEASTERN STATES. STORMS WILL BE MOST NUMEROUS
ALONG THE WESTERN AND CENTRAL GULF COAST WHERE DEEPER MOISTURE
WILL BE IN PLACE.

THE CORE OF THE UPPER-LEVEL RIDGE OF HIGH PRESSURE THAT BROUGHT A
HEAT WAVE TO THE CENTRAL U.S. HAS NOW MOVED WESTWARD, CENTERED
OVER THE FOUR CORNERS REGION. AS A RESULT, COOLER TEMPERATURES ARE
EXPECTED FOR MUCH OF THE CENTRAL U.S. TODAY AND TUESDAY, WITH
TEMPERATURES NEAR OR EVEN SLIGHTLY BELOW NORMAL ACROSS MUCH OF THE
CENTRAL AND SOUTHERN PLAINS. FARTHER EAST, HOWEVER, A REMNANT
PIECE OF THE HIGH PRESSURE RIDGE WILL PERSIST ACROSS THE SOUTHERN
MID-ATLANTIC TODAY, KEEPING HOT TEMPERATURES IN PLACE ALONG MUCH
OF THE EAST COAST. HEAT ADVISORIES REMAIN IN EFFECT THROUGH TODAY
FOR MUCH OF THE EASTERN SEABOARD.
