SHOWERS AND THUNDERSTORMS ARE EXPECTED ALONG AND AHEAD OF A COLD
FRONT TRACKING EASTWARD THROUGH THE CENTRAL PLAINS TO THE UPPER
MISSISSIPPI VALLEY/GREAT LAKES REGION. EMBEDDED AREAS OF HEAVY

ARE FREQUENT LIGHTNING, SEVERE THUNDERSTORM WIND GUSTS, HAIL, AND
A MINIMAL THREAT OF TORNADOES. MEANWHILE, A QUASI-STATIONARY FRONT
OVER THE MID-ATLANTIC WILL AID IN PRODUCING SHOWERS AND STRONG TO
SEVERE THUNDERSTORMS TODAY. SOUTH OF THE FRONT, UPPER-LEVEL
IMPULSES, DAYTIME HEATING, AND MOISTURE WILL CREATE SHOWERS AND
THUNDERSTORMS ON SUNDAY OVER THE OHIO/TENNESSEE VALLEYS, SOUTHERN
PLAINS, LOWER MISSISSIPPI VALLEY, AND THE SOUTHEAST. SIMILARLY,
UPPER-LEVEL IMPULSES, DAYTIME HEATING, AND MOISTURE WILL CREATE
SHOWERS AND THUNDERSTORMS OVER PARTS OF THE SOUTHERN HIGH PLAINS.
ALSO, ON SUNDAY, SCATTERED RAIN SHOWERS WILL DEVELOP OVER PARTS OF
NORTHERN NEW ENGLAND AS LOW PRESSURE MOVES EASTWARD INTO
SOUTHEASTERN CANADA.
ELSEWHERE, UPPER-LEVEL IMPULSES, DAYTIME HEATING, AND MOISTURE
WILL PRODUCE SHOWERS AND THUNDERSTORMS OVER PARTS OF THE SOUTHERN
MID-ATLANTIC/SOUTHEAST, THE GULF COAST STATES INTO THE
MIDDLE/LOWER MISSISSIPPI VALLEY AND THE CENTRAL/SOUTHERN PLAINS.
PARTS OF THE WEST WILL BE HEATING UP OVER THE NEXT FEW DAYS AS
UPPER-LEVEL RIDGING BUILDS OVER THE REGION. HEAT ADVISORIES ARE IN
