AREA FORECAST DISCUSSION

NATIONAL WEATHER SERVICE WAKEFIELD VA

349 PM EST SAT JAN 22 2011

.SYNOPSIS...

LOW PRESSURE WILL TRACK NORTHEAST OFF THE MID ATLANTIC COAST AND

FARTHER OUT TO SEA TONIGHT INTO SUNDAY. HIGH PRESSURE WILL BUILD

ACROSS THE GREAT LAKES AND INTO NEW ENGLAND SUNDAY AFTERNOON THROUGH

MONDAY. ANOTHER STORM SYSTEM WILL AFFECT THE REGION TUESDAY THROUGH

WEDNESDAY.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...

CLOUDY SKIES WILL PREVAIL ON TUE AND WED WITH THIS NEXT SYSTEM.

HAVE LEANED HEAVILY ON THE ECMWF SOLN AND HOW IT HAS STAYED VERY

CONSISTENT OVER THE LAST SEVERAL RUNS WITH THE H70 LOW POSITION

AND TRACK OF THIS NEXT SYSTEM. I CAN NOT SAY THE SAME FOR THE GFS

AND ITS GEFS SOLNS NOT ABLE TO COME TO ANY ONE FAIRLY CONSISTENT

TRACK. SO WITH THIS IN MIND...THE GFS AND DGEX ARE THE FURTHEST

EAST OF SOLUTIONS FOR TODAY. SINCE IT IS DAY 4/DAY 5 PERIOD...THIS

IS USUALLY WHERE SOME MODELS WILL DO A DRAMATIC JUMP EAST TO ONLY

QUICKLY CHANGE ITS MIND OR SLOWLY TREND BACK WESTWARD TO THE

ORIGINAL SOLNS OVER THE NEXT SERIES OF RUNS. WE HAVE ALREADY SEEN

THIS WITH THE COASTAL CAROLINA SYSTEM TODAY. 84 HRS AGO...ALL SHRT

RANGE GUIDANCE KEPT THE SYSTEM WAY OFFSHORE AND LITTLE BY LITTLE

HAVE TRENDED BACK CLOSER TO THE COAST.

STILL GNRLY KEEPING THE WARMER SOLN OF MODELS WITH THINKING OF

PHASING TO DVLP LATER WITH THE NRN/SRN STREAMS. NEW EURO IS SLOWER

WITH PRECIP START THEREFORE...PRECIP WILL NOT INITIALLY START TILL

AFT 12Z TUE (IF NOT LATER AM AS TRENDS CONTINUE TO SLOW ITS

NORTHWARD TREND). THE HIGH TO THE NORTH IS BECOMING MORE OF A

PROBLEM FOR MODELS TO HANDLE WHEN AND HOW FAR NORTH THIS SYSTEM WILL

REACH WITH THE HIGH SITUATED OFF THE NORTHEAST COAST. THE LONGER IT

TAKES TO MOVE UP THE COAST...THE CLOSER TO THE COAST IT WILL

EVENTUALLY TRACK AS THE HIGH WILL BE FURTHER OFFSHORE. AS OF

NOW...PRECIP LOOKS TO START OUT AS LIGHT RAIN OVER THE FAR S/SE TUE

AM. AS PRECIP SHIELD PUSHES TO THE NORTH OVER THE CWA...LOOK FOR IT

TO BE COLD ENOUGH INITIALLY FOR SNOW TO A WINTRY MIX OVER THE

CENTRAL SECTIONS WITH -SN GNRLY OVER THE NWRN THIRD. PRECIP WILL

TRANSITION TO MORE OF A RAIN SOLN TUE EVE AS WARMER AIR TRIES TO

FILTER INTO THE RGN AT 850 LVLS (MORE OF A RA/SLEET SOLN OVER THE NW

THIRD). HAVE TRENDED A BIT FURTHER EAST WITH THE RA/SN LINE ON WED

WITH MORE CHCS OF SN OVER WRN THIRD. PAST FEW RUNS OF THE ECMWF

WOULD SUPPORT H85-50 FRONTOGENESIS DVLPG AFT 06Z WED THROUGH AROUND

15Z WED. OVERLAYING THIS WITH WHERE THE SE H70 WINDS INTERSECT THE

+/- H85 THERMALS...THERE IS NOW BETTER SHOT OF SIGNIFICANT THERMAL

DIFFERENCE TO SEE DECENT COLLISION AND COALESCENCE FOR A GOOD SHOT

OF MOD/HVY PRECIP WHERE THE RA/SN LINE EXISTS. TAKING TOTAL

VERBATIM...MORE OF AN ACCUMULATION WILL DVLP OVER THE EASTERN

SECTIONS OF THE METRO RICHMOND AREA AND INTO THE MIDDLE AND NRN NECK

AND INTO WRN SECTIONS OF THE ERN SHORE. FOR NOW...HAVE CRNTLY STAYED

FURTHER TO THE WEST (WITH TRENDS OF SYSTEMS OF LATE) AND KEPT BETTER

ACCUM CHCS FURTHER INLAND. BEAR IN MIND...ITS STILL WAY TOO EARLY

TO PROJECT ANY SN/PL ACCUMS AND RAIN AMOUNTS. HOWEVER...STILL

THINKING THIS WOULD BE THE AREA TO CONTINUE TO WATCH FOR POSSIBLE

ACCUMS OF SN/PL.

SOME WRAP AROUND MOISTURE WILL EVENTUALLY DEVELOP...AND COULD SEE

SOME ACCUMS REACH FURTHER ALONG THE COAST BEFORE ENDING AS

FLURRIES....TIME WILL TELL. ANOTHER COLD AIR PUSH DVLPS BEHIND THIS

SYSTEM (BUT MODERATES) LATE WK AHEAD OF NEXT SYSTEM EARLY NEXT WK.

Down to 10.0 now.

Tuesday: A slight chance of rain and snow after 1pm. Mostly cloudy, with a high near 38. Chance of precipitation is 20%.

Tuesday Night: A chance of snow before 1am, then a chance of rain and sleet. Cloudy, with a low around 33. Chance of precipitation is 50%.

Wednesday: A chance of snow and sleet. Cloudy, with a high near 37. Chance of precipitation is 50%.

Wednesday Night: A chance of snow showers. Mostly cloudy, with a low around 28. Chance of precipitation is 30%.

Can I split the difference with these temps in the forecast? Low 20s with some moisture would be better than 10 and dry.

Why? They look like a blend of just about all the models. Probably a safe bet at this range.

is this laughable? based on most of the data, I think DT's stands a better chance of verifying.

Maybe laughable is too strong of a word.

My point was that I don't think he should release any sort of map until Sunday night or Monday morning at the earliest, but that is just my opinion I guess. Also he has no mention of the possibility for back-end snows in area B which is sort of misleading.
