NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
304 AM EDT SAT JUL 30 2016

VALID 12Z SAT JUL 30 2016 - 12Z MON AUG 1 2016

...HEAVY RAIN AND STRONG STORMS LIKELY FROM THE LOWER MISSISSIPPI
VALLEY
TO THE MID-ATLANTIC THROUGH THIS WEEKEND...

...HOT WEATHER FROM THE DESERT SOUTHWEST TO TEXAS...

A SLOW MOVING AREA OF LOW PRESSURE ALONG A FRONTAL BOUNDARY IS
EXPECTED TO BRING WIDESPREAD MODERATE TO LOCALIZED HEAVY RAINFALL
FROM THE NORTHERN OHIO VALLEY TO THE MID-ATLANTIC AND NORTHEAST
FOR THIS WEEKEND, WITH THE HEAVIEST RAINFALL LIKELY FALLING OVER
PENNSYLVANIA.  THE TRAILING FRONT WILL EXTEND WESTWARD TO THE
CENTRAL PLAINS, WHERE NUMEROUS SHOWERS AND THUNDERSTORMS ARE
LIKELY TO DEVELOP FROM NEBRASKA TO ARKANSAS.  SOME SEVERE
THUNDERSTORMS WILL ALSO BE POSSIBLE.

DIURNAL THUNDERSTORM ACTIVITY IS LIKELY NEAR THE GULF COAST AND
FLORIDA, WITH PEAK COVERAGE DURING THE AFTERNOON AND EVENING
HOURS.  NORTH OF THE FRONTAL BOUNDARY, A COOLER AND MORE PLEASANT
AIR MASS WILL BE ENJOYED ACROSS THE UPPER MIDWEST AND NORTHERN
GREAT LAKES REGION.  HOT AND DRY CONDITIONS ARE EXPECTED TO
CONTINUE ACROSS MUCH OF TEXAS WITH NO MAJOR FORCING MECHANISMS FOR
ORGANIZED RAINFALL EXPECTED.

ACROSS THE WESTERN U.S., SCATTERED SHOWERS AND STORMS ARE EXPECTED
TO DEVELOP EACH AFTERNOON, WITH THE BEST CONCENTRATION ACROSS THE
ELEVATED REGIONS OF ARIZONA AND NEW MEXICO WITH MOISTURE FROM THE
MONSOON.  IT WILL ALSO BE QUITE HOT ACROSS THE LOWER ELEVATIONS OF
THE DESERT SOUTHWEST.  A BREAK IN THE UPPER LEVEL RIDGE AND A
DEVELOPING COLD FRONT WILL BRING COOLER CONDITIONS FOR THE PACIFIC
NORTHWEST GOING INTO THE WEEKEND.
