SHORT RANGE FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
440 AM EDT THU APR 24 2014

VALID 12Z THU APR 24 2014 - 12Z SAT APR 26 2014

...THE THREAT FOR SEVERE WEATHER WILL SET UP ACROSS THE LOWER AND
MIDDLE MISSISSIPPI VALLEY TODAY...

...RAIN AND MOUNTAIN SNOW WILL BE COMMONPLACE OUT WEST THROUGH THE
END OF THE WEEK...

A STORMY WEATHER PATTERN WILL REMAIN IN PLACE ACROSS THE U.S. WITH
THREE SIGNIFICANT STORM SYSTEMS TO IMPACT THE LOWER 48. ONE OF
THESE SYSTEMS IS ONGOING NEAR NEW ENGLAND THIS MORNING IN THE FORM
OF A SLOW MOVING LOW PRESSURE CENTER. WHILE THE STORM`S EFFECTS
ARE MOSTLY OFFSHORE AT THIS POINT, MAINE WILL CONTINUE TO FEEL THE
EFFECTS TODAY WITH BREEZY WINDS ALONG WITH RAIN AND POSSIBLY SNOW
SHOWERS MIXING IN NEAR HIGHER ELEVATIONS.

THE IMMEDIATE HAZARDOUS WEATHER CONCERN WILL BE ACROSS THE
MISSISSIPPI VALLEY LATER TODAY AHEAD OF A COLD FRONT WITH A THREAT
FOR TORNADOES, LARGE HAIL AND STRONG STRAIGHT LINE WINDS ACCORDING
TO THE STORM PREDICTION CENTER. LOCALLY HEAVY RAIN WILL ACCOMPANY
THUNDERSTORMS NEAR THE COLD FRONT BUT LARGE SCALE FLOODING SHOULD
NOT BE AN ISSUE. OUTSIDE OF NEW ENGLAND, MUCH OF THE EAST COAST
WILL SEE PLEASANT SPRING WEATHER TODAY BUT RAIN WILL MOVE INTO THE
REGION FOR FRIDAY IN CONNECTION WITH THE ADVANCING COLD FRONT.

TEMPERATURES WILL WARM QUICKLY ACROSS THE SOUTHERN AND CENTRAL
PLAINS FOR FRIDAY AND SATURDAY OUT AHEAD OF ANOTHER STORM SYSTEM
MOVING INTO THE WESTERN UNITED STATES. AN UPPER LEVEL TROUGH WILL
AMPLIFY ACROSS THE WEST ON FRIDAY WHILE A COLD FRONT SLOWLY MOVES
THROUGH THE INTERMOUNTAIN REGION. SCATTERED RAIN SHOWERS WILL
CHANGE TO SNOW SHOWERS, MOSTLY ACROSS THE HIGHER ELEVATIONS OF THE
SIERRA NEVADA AND SAWTOOTH RANGES WHERE LOCALLY HEAVY SNOWFALL IS
LIKLEY. LOWER ELEVATIONS OUT WEST WILL STAY MOSTLY RAIN, WITH SNOW
MIXING IN DEPENDING ON ELEVATION. AS THE UPPER LEVEL DISTURBANCE
CONTINUES EAST ON SATURDAY, THE BEGINNING OF AN ACTIVE SEVERE
WEATHER SETUP APPEARS LIKELY, WITH THREATS CONTINUING THROUGH THE
WEEKEND.
