000 FXUS01 KWBC 302035 PMDSPD SHORT RANGE FORECAST DISCUSSION NWS WEATHER PREDICTION CENTER COLLEGE PARK MD 434 PM EDT MON MAR 30 2015 VALID 00Z TUE MAR 31 2015 - 00Z THU APR 02 2015 ***MODERATING TEMPERATURES ACROSS THE EASTERN U.S.*** ***SNOW LIKELY FROM THE GREAT LAKES TO UPSTATE NEW YORK*** ***RAIN AND MOUNTAIN SNOW RETURNING TO THE PACIFIC NORTHWEST*** WARMER TEMPERATURES HAVE ARRIVED TO THE EASTERN THIRD OF THE U.S. AFTER A COLD WEEKEND. THIS IS ESPECIALLY THE CASE FOR THE MID-ATLANTIC AND SOUTHEAST U.S., WITH HIGH TEMPERATURES CLOSE TO SEASONAL AVERAGES. THE EXCEPTION TO THIS WILL BE NEW ENGLAND AND UPSTATE NEW YORK, WHERE HIGHS WILL LIKELY REMAIN BELOW 50 DEGREES OVER THE NEXT FEW DAYS. A DISTURBANCE TRACKING SOUTHEASTWARD FROM THE GREAT LAKES ON TUESDAY HAS THE POTENTIAL TO BRING ACCUMULATING SNOW FROM MICHIGAN TO NORTHERN PENNSYLVANIA AND SOUTHERN NEW YORK, WITH SCATTERED AREAS OF RAIN TO THE SOUTH ACROSS PARTS OF THE MID-ATLANTIC. THIS SYSTEM SHOULD BE QUICK-MOVING AND BE OFFSHORE BY WEDNESDAY MORNING. UNLIKE PREVIOUS SYSTEMS THIS PAST WINTER, THERE IS NOT REALLY ANY SEVERE ARCTIC COLD WEATHER BEHIND IT, AND THAT SHOULD REMAIN OVER CANADA. A COLD FRONT APPROACHING THE PACIFIC NORTHWEST WILL BRING SCATTERED SHOWERS AND MOUNTAIN SNOW BACK INTO THE FORECAST GOING THROUGH WEDNESDAY MORNING. THE HEAVIEST SNOWFALL IS LIKELY TO OCCUR JUST NORTH OF THE BORDER INTO SOUTHERN BRITISH COLUMBIA. UNFORTUNATELY, AREAS TO THE SOUTH IN CALIFORNIA AND NEVADA ARE EXPECTED TO REMAIN DRY WHERE THE SEVERE DROUGHT IS ONGOING. TOWARDS MIDWEEK, THIS SYSTEM WILL BEGIN TO EMERGE OVER THE GREAT PLAINS AND ALLOW FOR VERY WARM TEMPERATURES ACROSS THE CENTRAL AND SOUTHERN PLAINS BEFORE THE COLD FRONT PASSES THROUGH. D.
