Latest Forecast Discussion From the Main National Weather Service Forecast Prediction Center Outside of Washington D.C.

I have been following the guy who put this discussion together for many years. He is one of the best forecasters in the country in my opinion. 



EXTENDED FORECAST DISCUSSION

VALID 12Z TUE MAR 25 2014 - 12Z SAT MAR 29 2014

...NOR'EASTER TO BOMB OFF THE MID-ATLANTIC COAST LATE TUESDAY...

THE CROSS-POLAR FLOW WHICH HAS PERIODICALLY REACHED INTO NORTH

AMERICA SINCE JANUARY SEEMS DESTINED FOR AT LEAST ONE MORE

TRANSPORT OF ARCTIC AIR INTO MUCH OF THE CENTRAL AND EASTERN

UNITED STATES TUESDAY. WITH HEIGHTS STILL LOW ACROSS THE EAST IN

THE WAKE OF THE COLD BLAST DURING SUNDAY AND MONDAY IN THE SHORT

RANGE, THE STAGE WILL BE SET FOR ANOTHER ROUND OF SNOW AND ICE

WITH THE CLIPPER SYSTEM HERALDING TUESDAY'S OUTBREAK. IT SEEMS

THAT THE CLIPPER WILL GAIN ENOUGH AMPLITUDE TO SIPHON SOME

SUBTROPICAL MOISTURE AND ENERGY CROSSING THE SOUTHEAST FROM THE

GULF OF MEXICO EARLY TUESDAY. MOST OF THE GLOBAL NUMERICAL MODELS

INDICATE THAT THE SLIGHT NEGATIVE-TILT TO THE CLIPPER WILL SET UP

A DUMBBELLING WITH THE GULF ENERGY TOWARD EVENING TUESDAY

SOMEWHERE OFFSHORE BETWEEN CAPE HATTERAS AND THE ATLANTIC

"BENCHMARK" OF 40N/70W. THIS BINARY INTERACTION--OR FUJIWHARA

EFFECT--IS A PARTICULARLY ENERGIZING PHENOMENON. BY EARLY

WEDNESDAY MORNING, A SUB-970MB SURFACE CYCLONE IS LIKELY NEAR THE

BENCHMARK AFTER THE BOMBING PHASE. HOW FAR SOUTHWEST THE BOMBING

OCCURS IS CRITICAL FOR THE SENSIBLE WEATHER FROM THE CAROLINAS TO

NEW ENGLAND. THE EARLIER/FARTHER SOUTHWEST, THE GREATER THE

CHANCES FOR SIGNIFICANT WINTER WEATHER FROM THE CAROLINAS AND

SOUTHERN MID ATLANTIC ALL THE WAY THROUGH MAINE. IF THE BOMBING IS

LATER/FARTHER NORTHEAST, EASTERN NEW ENGLAND WOULD SUFFER THE

WORST EFFECTS. EITHER WAY, WINDS LOOK REMARKABLY STRONG ON THE

WEST AND SOUTH SIDE OF THE TIGHT CIRCULATION TUESDAY NIGHT INTO

EARLY WEDNESDAY--A MAJOR CONCERN FOR COASTAL AND OFFSHORE

INTERESTS FROM EASTERN LONG ISLAND TO DOWN EAST MAINE.

AFTER THE EAST-COAST STORM, THE AMPLITUDE OF THE FLOW ACROSS THE

NATION SHOULD RELAX SOME, THOUGH THE GENERAL BACKGROUND PATTERN

APPEARS TO REMAIN. USED A RECENT ECENS MEAN TO HANDLE THIS PHASE

OF THE FORECAST. THE NORTHWEST SHOULD CONTINUE TO BE UNSETTLED IN

STRONG ONSHORE FLOW, WITH THE SOUTHWEST RELATIVELY SHELTERED DUE

TO THE SPLITTING. MUCH OF THE EASTERN UNITED STATES LOOKS WET,

WITH THE GULF OF MEXICO OPENING VIA RESIDUAL BROAD TROUGHING.
