NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
249 AM EDT TUE JUL 26 2016

VALID 12Z TUE JUL 26 2016 - 12Z THU JUL 28 2016

...SEVERE THUNDERSTORMS AND HEAVY RAIN POSSIBLE TODAY FOR PORTIONS
OF THE CENTRAL/NORTHERN PLAINS...

...WET CONDITIONS EXPECTED TO DEVELOP ALONG THE GULF COAST...

...ABOVE AVERAGE TEMPERATURES EXPECTED TO CONTINUE ACROSS THE EAST
AND THE WEST THROUGH MID-WEEK...

A STATIONARY FRONTAL BOUNDARY WILL LINGER FROM THE MID-ATLANTIC
REGION TO THE MID-MISSISSIPPI VALLEY TO THE CENTRAL PLAINS THROUGH
THE MIDDLE OF THE WEEK. AS A RESULT, SCATTERED SHOWERS AND
THUNDERSTORMS WILL BE POSSIBLE MUCH OF THE EASTERN TWO THIRDS OF
THE NATION. SHOWERS AND THUNDERSTORMS WILL BE MORE NUMEROUS IN A
COUPLE AREAS TODAY, INCLUDING THE CENTRAL/NORTHERN PLAINS AND THE
GULF COAST. A WEAK WAVE OF LOW PRESSURE ALONG THE FRONTAL BOUNDARY
WILL FOCUS AN AREA OF SHOWERS AND THUNDERSTORMS TODAY ACROSS THE
CENTRAL AND NORTHERN PLAINS. THESE STORMS COULD BE SEVERE AS WELL
AS PRODUCING HEAVY RAINFALL. PLEASE REFER TO PRODUCTS ISSUED BY
THE STORM PREDICTION CENTER FOR MORE DETAILS ON THE SEVERE WEATHER
THREAT.

ALONG THE GULF COAST, A BROAD AREA OF LOW PRESSURE AT THE MID AND
UPPER-LEVELS OF THE ATMOSPHERE ALONG WITH DEEP, TROPICAL MOISTURE
WILL SUPPORT NUMEROUS SHOWERS AND THUNDERSTORMS TODAY AND
WEDNESDAY, PARTICULARLY ACROSS THE CENTRAL GULF COAST STATES.
HEAVY RAINFALL WILL BE POSSIBLE IN THIS AREA AS WELL. SHOWER AND
STORMS ARE FORECAST TO BECOME MORE WIDESPREAD FARTHER NORTH ON
WEDNESDAY AS WELL, ACROSS THE LOWER AND MID-MISSISSIPPI VALLEY.

ABOVE AVERAGE TEMPERATURES ARE FORECAST TO CONTINUE ALONG MUCH OF
THE EASTERN U.S. THROUGH MID-WEEK. AFTERNOON HIGH TEMPERATURES
TODAY AND WEDNESDAY WILL AGAIN BE 5 TO 10 DEGREES ABOVE AVERAGE
FOR MANY AREAS. HEAT ADVISORIES REMAIN IN EFFECT FOR PORTIONS OF
VIRGINIA AND THE CAROLINAS. ACROSS THE WEST, HIGH PRESSURE ALOFT
WILL KEEP DRY CONDITIONS IN PLACE THROUGH MID-WEEK, WITH AFTERNOON
HIGH TEMPERATURES EXPECTED TO BE 5 TO 15 DEGREES ABOVE AVERAGE.
