...SEVERE THUNDERSTORMS AND HEAVY RAIN POSSIBLE FROM THE CENTRAL
PLAINS TO THE MIDWEST...

...GRADUALLY RISING TEMPERATURES EXPECTED ACROSS THE WEST COAST
STATES...

AN ACTIVE WEATHER PATTERN WILL BE IN PLACE FROM THE PLAINS TO THE
GREAT LAKES THROUGH THE NEXT COUPLE DAYS. A FRONTAL SYSTEM WILL
BRING SHOWERS AND THUNDERSTORMS TO AREAS FROM THE CENTRAL PLAINS
TO THE MIDWEST AND GREAT LAKES TODAY AND TONIGHT. SEVERE
THUNDERSTORMS WILL BE POSSIBLE ALONG WITH HEAVY RAINFALL. PLEASE
REFER TO PRODUCTS ISSUED BY THE STORM PREDICTION CENTER FOR
FURTHER DETAILS ON THE SEVERE WEATHER THREAT. THURSDAY AND
THURSDAY NIGHT, A ROUND OF SHOWERS AND STORMS WILL MOVE FROM THE
GREAT LAKES INTO THE NORTHEAST AS THE INITIAL FRONTAL WAVE MOVES
INTO SOUTHEASTERN CANADA. MEANWHILE, ANOTHER AREA OF LOW PRESSURE
IS FORECAST TO DEVELOP ALONG THE FRONT ACROSS THE CENTRAL PLAINS,
SPREADING ANOTHER ROUND OF SHOWERS AND STORMS FROM THE CENTRAL
PLAINS TO THE MIDWEST. SEVERE THUNDERSTORMS AND HEAVY RAINFALL
WILL ONCE AGAIN BE POSSIBLE.

ELSEWHERE, INCREASING MOISTURE AND INSTABILITY WILL RESULT IN A
GRADUAL INCREASE IN SHOWERS AND STORM ACROSS THE SOUTHERN TIER.
STORM SHOULD REMAIN CONFINED GENERALLY ALONG THE GULF COAST TODAY.
SCATTERED SHOWERS AND STORMS ARE EXPECTED FARTHER INLAND ACROSS
THE SOUTHEAST ON THURSDAY, HOWEVER. FARTHER WEST, AFTER A BRIEF
COOL DOWN, TEMPERATURES ARE EXPECTED TO BEGIN RISING ONCE AGAIN
THROUGH THE END OF THE WORK WEEK AS HIGH PRESSURE ALOFT BUILDS
INTO THE REGION. HIGH TEMPERATURES ON THURSDAY ARE FORECAST TO BE
5 TO 10 DEGREES ABOVE AVERAGE ACROSS THE WEST COAST STATES, WITH
TEMPERATURES RISING FURTHER BY FRIDAY. TEMPERATURES THROUGH FRIDAY
ARE EXPECTED TO REMAIN BELOW THE EXTREME LEVELS EXPERIENCED IN
RECENT DAYS, HOWEVER.
