Possible Major Eastern Storm on the way???

[Hybridstorm_November2001]

...CENTRAL US...

06Z GFS SENT HEART OF COLD AIR THRU THE ERN PLAINS...WITH MARKED
CHINOOK CONDITIONS DRIVEN BY PROGRESSIVE HIGH AMPLITUDE RIDGE OVER
WRN CANADA. LATEST GUIDANCE GIVES CONFLICTING SIGNALS...WITH
SEVERAL MODELS DRAPING A MODIFIED ARCTIC AIRMASS ACROSS THE NRN
TIER LATE IN THE PD.

...ERN US...

06Z GFS SENT BIG STORM UP THRU THE CENTRAL APPALACHIANS AND MID
ATL REGION D3-4...COURTESY OF VIGOROUS S/WV LIFTING FROM SWRN
STATES DURING THE SHORT RANGE. NOW OTHER GUIDANCE IS QUITE
UNDECIDED WITH THE EVOLUTION OF THIS SYSTEM...WITH THE POSSIBILITY
OF A DISTINCTLY MORE SUPPRESSED LOW TRACK. LATE IN THE
PD...SIGNALS ARE MIXED AS TO EXTENT OF COLD AIR OVER THE
REGION...WITH 06Z GFS SUGGESTING A MERIDIONAL DRIVE OF CP
AIR...AND OTHER MODELS MORE ZONAL.

Well, it looks like it'll be all rain but a pretty good Nor'easter.

BOMBS AWAY!!

I hope it is ALL RAIN. The track of this one is most uncertain; a more off shore & a tad deeper path, and we could get some decent snows for interior parts of the region. Need to keep a close eye of this one as it evolves.

A POTENT WEEKEND SYSTEM PASSAGE WILL FAVOR WIDESPREAD
LEAD...WRAP-BACK LOW...AND TRAILING COLD FRONTAL FOCUSING PCPN.
GREAT LAKE EFFECT SNOWS AND COOLING MAY ALSO BE ENHANCED AS A
SECONDARY SHOT OF COLD AIR FOLLOWS IN THE WAKE OF THE LEAD SYSTEM.
IN THIS PATTERN...PLAN FOR A MORE PROLONGED PCPN POTENTIAL FOR AT
LEAST SRN FL NEXT WEEK AS POOLED FRONTAL/TROPICAL MOISTURE AND
INFLOW MAY STALL OVER THE REGION.

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...

COOL HIGH PRESSURE OVER THE AREA WILL BRING A CLEAR TO PARTLY
CLOUDY AND CHILLY NIGHT FRIDAY NIGHT WITH TEMPS FALLING INTO THE
20S ACROSS MOST OF THE AREA. LOW PRESSURE OVER THE GREAT LAKES
SUPPORTED BY A STRONG TROUGH OF LOW PRESSURE IN THE UPPER MID WEST
WILL BEGIN TO APPROACH ON SATURDAY. SECONDARY LOW PRESSURE WILL
FORM NEAR SOUTHERN NEW ENGLAND AND RAPIDLY APPROACH SATURDAY
AFTERNOON SPREADING RAIN ACROSS THE AREA. BOUNDARY LAYER
TEMPERATURES NOW INDICATE THAT THE AIR WILL BE TOO WARM FOR SNOW
IN MOST AREAS...EVEN UP NORTH...HOWEVER TEMPS NEAR -3 AT 850
INDICATE THAT PRECIPITATION MAY BEGIN AS SNOW OVER SOME HIGHER
ELEVATIONS TO THE NORTH LATE SATURDAY INTO SATURDAY NIGHT. ANY
ACCUMULATIONS WOULD LIKELY BE CONFINED TO ELEVATIONS OVER 1200
FEET AND WOULD BE AN INCH OR LESS. STRONG WINDS AHEAD OF THE
SECONDARY LOW WILL MOVE ONTO THE DOWNEAST COAST SATURDAY
EVENING...POSSIBLY REQUIRING A WIND ADVISORY. AS THE LOW LIFTS
NORTH OF THE AREA SUNDAY IT INTENSIFIES TO BELOW 970 MB. COLDER
AIR AND MOISTURE WILL BE WRAPPING IN BEHIND THE LOW ON VERY STRONG
AND GUSTY WEST SOUTHWESTERLY WINDS. SNOW SHOWERS WILL BE LIKELY IN
THE NORTHWEST WITH A CHANCE OF RAIN AND SNOW SHOWERS
ELSEWHERE...AND SOME HEAVIER SNOW SQUALLS CAN`T BE RULED OUT
SUNDAY INTO SUNDAY NIGHT...ESPECIALLY IN THE HIGHER ELEVATIONS.
WIND ADVISORIES MAY BE NEEDED ACROSS THE STATE IN THE STRONG
GUSTY WINDS ON SUNDAY. THE LOW WILL GRADUALLY MOVE AWAY EARLY NEXT
WEEK.
