A deep anamolous trough looks to dig hard into the eastern CONUS, possibly all the way to the GOM bringing a SLP up out of the Gulf across the SE and possibly up the east coast. Could go without saying with this crowd...but a lot of disagreement if this tracks overland or over water, if the trough cuts off and trough orientation.

Both 0z GFS and CMC have the trough going negative earlier with a more explosive surface storm, also cutting the upper low off, allowing the storm to virtually stall. 0z Euro was much more progressive with the trough, keeping more positively tilted and not allowing explosive surface development.

Not many questions regarding p-type here unless maybe your trying to hike Mount Washington, NH....or Mount Marcy, NY. These spots though are well known to get snowstorms in late May & even June though...

I'll just post one 0z GEFS image...

I remember 20 yrs ago going to Tucks early May and 5 feet of new snow was in the bowl. It had rained for 4 days previous at lower elevations with temps in the 40's

Mmm...'96-97...

Just 4 years ago, we had the big Memorial day storm...was a bigger snow producer for the Adirondacks & Greens than the Whites, but pretty a pretty impressive late season storm:

There's a chance if the setup is right that snow could make it down pretty far. On May 16 of last year we had flakes in Bartlett and North Conway (which is at 500 ft elevation). Bretton Woods picked up an inch or more. We had 4" of snow April 26 last year in Bartlett/N Conway

12z GFS, GFS-P & CMC were all a disorganized mess with the trough cutting off too early so all that energy seems to get spit out in waves instead of a consolidated mass.

Think this was a NorEaster07 inspired post...but from June 16th last year:

00z Euro has a W Apps Runner look - indicating more of a temp contrast driven event, as opposed to a Nor. Of course, at D6 lead time, the spread seems to pretty wide.

EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
252 AM EDT SAT APR 29 2017

VALID 12Z TUE MAY 02 2017 - 12Z SAT MAY 06 2017

...PATTERN OVERVIEW AND GUIDANCE EVALUATION...

THE MAJORITY OF GUIDANCE CONTINUES TO SHOW AN EWD SHIFT OF THE
LARGE SCALE PATTERN, SETTLING INTO A SLOWER MOVING WEST COAST
TROUGH/CNTRL U.S. RIDGE/ERN TROUGH CONFIGURATION BY THE LATTER
PART OF THE PERIOD. THUS FAR GUIDANCE HAS NOT MADE MUCH PROGRESS
IN RESOLVING IMPORTANT DETAILS OF AMPLIFYING CNTRL-ERN U.S. UPR
TROUGH ENERGY LEADING TO SOME VERY DIFFERENT SFC EVOLUTIONS LATE
WEEK INTO THE WEEKEND. TROUGHING LIKELY TO REACH THE WEST COAST
LATE IN THE PERIOD SHOULD BE LESS EXTREME THAN THAT FCST OVER THE
EAST BUT THERE ARE ALSO SIGNIFICANT DIFFS AMONG THE GUIDANCE FOR
THAT TROUGH.

THE FIRST CONSIDERATION OF NOTE IS THAT 6-HRLY GFS RUNS FROM AT
LEAST AS FAR BACK AS 12Z HAVE BEEN FASTER THAN CONSENSUS,
INCLUDING GEFS MEANS, FOR FLOW ACROSS THE ALEUTIANS/NRN PAC BY DAY
4 WED. WITHIN ABOUT A DAY THIS LEADS TO ACCELERATION OF NERN PAC
TROUGH ENERGY ACROSS SRN CANADA BEYOND WHAT IS FCST BY NEARLY ALL
OTHER GUIDANCE THAT HOLDS ONTO A MORE ROBUST RIDGE INSTEAD.
MAJORITY GUIDANCE TREND OVER THE PAST DAY HAS BEEN STRONGER FOR
THE U.S./SRN CANADA RIDGE, SO THERE ARE SIGNIFICANT QUESTION MARKS
WITH GFS SPECIFICS OVER/NEAR THE LOWER 48 AFTER ABOUT EARLY THU.

TELECONNECTIONS RELATIVE TO STRONG POSITIVE HGT ANOMALIES OVER
ICELAND/SRN GREENLAND PROVIDE SUPPORT FOR THE UPR TROUGH FCST BY
MOST SOLNS TO SETTLE OVER THE WEST COAST, AND IN FACT LOOSELY
SUPPORT THE POTENTIAL FOR SOME SEPARATION AS SUGGESTED IN THE 12Z
ECMWF/ECMWF MEAN AND NOW THE 00Z CMC. THE 12Z CMC WAS JUST A
LITTLE DELAYED IN ITS UPR LOW FORMATION. RECENT GEFS MEANS HAVE
BEEN A LITTLE FARTHER WWD WITH THE TROUGH BUT WITHIN TYPICAL DAYS
6-7 ERROR RANGES AND MUCH CLOSER TO CONSENSUS THAN OPERATIONAL GFS
RUNS.

SOLNS FOR THE AMPLIFYING CNTRL INTO ERN U.S. TROUGH WERE
REASONABLY SIMILAR INTO ABOUT EARLY DAY 5 THU WITH INCREASING
DIVERGENCE THEREAFTER. THE PAST COUPLE DAYS HAVE FEATURED 12-HRLY
ECMWF RUNS ALTERNATING BTWN A CONSOLIDATED MID ATLC/NORTHEAST
SYSTEM (12Z RUNS) AND FLOW SEPARATION THAT RESULTS IN A SERN
SYSTEM AND MORE PROGRESSIVE NRN WAVE. RECENT GFS/CMC RUNS HAVE
ALSO BEEN WAFFLING BTWN THESE IDEAS, AND NOT SURPRISINGLY THE FULL
ENSEMBLE ENVELOPE FOR SFC LOWS REMAINS EXTREMELY BROAD. EVEN WITH
SUCH SPREAD THE ENSEMBLE MEANS CONTINUE TO BE FAIRLY CONSISTENT
WITH A CONSOLIDATED MID ATLC/NORTHEAST SYSTEM BY FRI-SAT. THE 12Z
GEFS MEAN WHOSE SFC REFLECTION WAS BRIEFLY WEAKER/N-S ELONGATED
AROUND FRI WAS ONE EXCEPTION BUT THE 18Z RUN RETURNED BACK TO THE
GENERAL MULTI-RUN ENSEMBLE MEAN CONSENSUS. THE HIGH UNCERTAINTY
IN SPECIFICS GREATLY FAVORS MAINTAINING THE ENSEMBLE MEAN SCENARIO
FOR THE DETERMINISTIC FCST.

FOR THE DAYS 3-5 TUE-THU PART OF THE FCST, AGREEMENT WAS
SUFFICIENTLY GOOD TO SUPPORT A BLEND CONSISTING OF MOSTLY
OPERATIONAL 12Z-18Z GFS/12Z ECMWF RUNS. THEN AS GUIDANCE DIVERGED
THE 18Z GEFS/12Z ECMWF MEANS BECOME THE DOMINANT COMPONENTS OF THE
FCST FOR DAYS 6-7 FRI-SAT WITH THE 12Z ECMWF STILL CLOSE ENOUGH TO
THE MEANS TO ALLOW A MINORITY WEIGHTING OF ITS FCST.


...WEATHER HIGHLIGHTS...

AFTER TUE EXPECT CONDITIONS OVER THE MIDWEST/GRTLKS TO MODERATE AS
A COLD/WINDY SHORT RANGE SYSTEM CONTINUES ON ITS WAY ACROSS SERN
CANADA. EXPECT SOME HIGHS OF 10-20F BELOW NORMAL TUE FOLLOWED BY
TEMPS THAT MAY REMAIN BELOW NORMAL FOR ONE OR MORE DAYS BUT WITH
LESS EXTREME ANOMALIES.

ENERGY ALOFT SUPPORTING THE EVENTUAL CNTRL-ERN U.S. SYSTEM WILL
FIRST BRING A BAND OF RAIN/HIGH ELEV SNOW SEWD ACROSS THE ROCKIES
AND THEN EXTEND RAIN/CONVECTION INTO THE PLAINS AS A SRN PLAINS
SFC WAVE DEVELOPS TUE-TUE NIGHT. THEN EXPECT AREAS OF HEAVY RAIN
TOWARD THE GULF COAST/LWR MS VLY BY WED WITH AN EWD-NEWD
EXPANSION/PROGRESSION OF THE MSTR SHIELD THEREAFTER. WIDE SPREAD
IN POTENTIAL EVOLUTION SFC/ALOFT MAINTAINS LOW CONFIDENCE IN
COVERAGE/LOCATION OF HEAVIEST RNFL OVER THE EAST BY LATE
WEEK/WEEKEND
. CURRENTLY THE BEST POTENTIAL FOR HIGHEST TOTALS
DURING THE PERIOD EXTENDS FROM THE LWR MS VLY/CNTRL GULF COAST
THROUGH THE MID ATLC INTO THE NORTHEAST
. DEPENDING ON SYSTEM
DETAILS THERE MAY BE ALSO ONE OR MORE BANDS OF ENHANCED RNFL TO
THE NW OF THIS AXIS. SOME CONVECTION MAY BE STRONG TO SEVERE BUT
CURRENT GUIDANCE DIFFS MAKE IT DIFFICULT TO PINPOINT FAVORED AREAS
FOR SUCH THREATS AT THIS TIME
.

STRONG RIDGE ALOFT BUILDING INTO/ACROSS THE WEST WILL BRING VERY
WARM TO HOT TEMPS TO THE REGION, WITH AN EVENTUAL COOLING TREND
OVER THE WEST COAST STATES BY SAT AS UPR TROUGHING APPROACHES
WHILE THE WARMTH SPREADS EWD INTO THE ROCKIES/HIGH PLAINS. THE
BROADEST EXPANSE OF PLUS 10-20F ANOMALIES FOR HIGHS SHOULD BE
AROUND THU-FRI. CURRENTLY EXPECT SOMEWHAT HIGHER POTENTIAL FOR
SCATTERED DAILY RECORD WARM LOWS VS RECORD HIGHS. ON THE OTHER
HAND THE STRENGTHENING CNTRL-ERN U.S. UPR TROUGH AND ASSOC SFC
SYSTEM WILL BRING AN EXPANDING AREA OF BELOW NORMAL TEMPS FROM
PARTS OF THE ROCKIES/HIGH PLAINS TOWARD THE EAST COAST, LIKELY
INCLUDING SOME POCKETS OF AT LEAST MINUS 10F ANOMALIES.

VALID 12Z TUE MAY 02 2017 - 12Z SAT MAY 06 2017

...15Z UPDATE...

THE GUIDANCE AS A WHOLE IS IN ALMOST COMPLETE AGREEMENT THROUGH
WED, ALOFT AND AT THE SURFACE. THIS INCLUDES THE DEPARTURE OF THE
DEEP CYCLONE DEPARTING THE UPPER MIDWEST AND GREAT LAKES REGION
ALONG WITH ITS ASSOCIATED COLD FRONT SWEEPING THROUGH THE ERN
THIRD OF THE COUNTRY. ALSO, THE ASSORTMENT OF SHORT WAVE DYNAMICS
DROPPING SOUTH AND EAST FROM THE NRN ROCKIES AND WEST CENTRAL
CANADA TOWARD THE CENTRAL/SRN PLAINS AND MID/LOWER MS VALLEY IS
HANDLED REASONABLY WELL WITH AMPLIFICATION OF A SHARP SPLIT FLOW
UPPER TROUGH BUT RESULTANT PRECIPITATION ON WED AT LEAST HAS LARGE
SPREAD. THIS SPREAD WITH QPF BEGINS TO IMPACT MASS FIELDS PRETTY
SIGNIFICANTLY THURS THROUGH SAT, AS OPERATIONAL GUIDANCE DIFFER
QUITE A BIT ON THE TROUGH PHASING AND/OR NON-PHASING ALONG WITH
FORWARD PROGRESSION OF THIS LARGE SCALE FEATURE DOWNSTREAM
. THE
00Z ECMWF HAS SHIFTED GEARS AND TRENDED TOWARD A MORE PHASED AND
PROGRESSIVE LONG WAVE TROUGH WITH NEG TILT MOVING THROUGH ERN
THIRD-TWO THIRDS OF COUNTRY. THE LAST SEVERAL RUNS OF THE GFS,
INCLUDING THE 00Z/06Z RUNS, KEEPS JETS SEPARATE AND A LARGE
BOWLING BALL ROLLING THROUGH THE SRN TIER OF THE COUNTRY. THIS IS
A COMPLETE FLIP FROM YESTERDAY OF PHASED, PROGRESSIVE SYSTEM. SO,
THE ECMWF NOW LOOKS LIKE YESTERDAYS GFS AND GFS LOOKS LIKE ECMWF,
GO FIGURE.
WPCS APPROACH IS MEANS, ECMWF/GEFS/NAEFS WITH 00Z
NAVGEM ON A UNIFORM AMPLIFIED UPPER TROUGH ROLLING EAST AND NEG
TILTING BY END OF PERIOD WITH VERY, VERY SMALL PERCENTAGES OF THE
GFS/ECMWF. BASICALLY REMOVING THE VARYING DETAILS BUT KEEPING THE
SRN STREAM/MARITIME JET THE MOST ACTIVE AND STRONG CONTINUITY FROM
OVERNIGHT.

One thing that seems to be for sure, it looks to be a pretty soggy week ahead for almost the entire eastern CONUS:

There is very high confidence that this will be a wet and unsettled
period. In fact...our forecast area will most likely be on the
receiving end of another significant rainfall...something that we do
not need after one of the wettest April`s in recorded history. The
GEFS and ECMWF based ensembles (including the operational runs) are
in strong agreement that an unusually well organized storm for early
May will track from the Tennessee Valley across our forecast area.
This system will be more typical of a mid winter storm...both in its
intensity...upper level support and overall structure. The only
difference is that temperatures will be some 5 deg c too high for a
major snowstorm. That being said...


QUOTE
The pending storm system will be supported by a highly amplified
pattern...again...more typical of mid winter. A very strong...full
latitude ridge will be anchored over the western states while an
anomalously deep trough (-3 STD) with an early May return interval
of once every 10 years will be found over the eastern third of the
country. Despite the impressive climatology behind this pattern...
there will initially be two distinct branches within the deep
trough. The wet storm system that will bring a substantial rainfall
to our region will be found within the southern branch...but as we
work through the weekend...very robust energy within the northern
branch will dive south across the Upper Great Lakes to phase the two
into a broad closed low that will largely reside over western Quebec


QUOTE
Digging deeper into the details of this storm system...it will
already be raining across all of our forecast area as we open this
period Thursday evening...but the most significant rain will be yet
to come. A strongly divergent upper level flow will be in place
across the Lower Great Lakes Thursday night...while even stronger
forcing aloft will be generated from a coupled H25 jet. Meanwhile in
the low levels...increasing baroclinicity in the H925-85 layer will
establish a steep surface for a 40-50kt low level jet to impinge up
on. All of this lift will be accompanied by a wealth of Atlantic
moisture that will extend back across our region from the Delmarva
Peninsula. This will boil down to a steady rain Thursday...which
could prove to be heavy at times...mainly over the western counties.
Have taken the lead and raised pops to 90 regionwide.

This storm is beginning to remind me of a similar system that affected us on May 5-6, 1989, though that storm's low was in a different place. Places to our west--notably the Rochester area--had major snow accumulations on the back end.

Really wish I m ew more about what to expect with this system for northern Virginia / D.C. On Saturday.

I'm supposed to photograph an air show and I'm not sure if I should commit or not. Clouds seem almost certain - not sure if ceilings will be low enough to call it a bust yet, but getting close.

Most precip (and lots of it..) seems to be Friday?

Man it is really coming down out there. Down at BWI for the overnight shift and have had so far .25" not really seeing much in the way of convective activity so far but seems like this thing, as we get closer to the front, will develop a mechanically forced line to form and not only drop some rather heavy rains but bring with it some strong winds with it maybe 40-50mph and higher in some spots. I really cant rule out the possibility of a tornado or two in areas south of the PA/MD border as you have decent vorticity as well strong veering, the cape is not there but the forcing of the system may be enough to sustain rotation.

Looking like it will be about 1-1.5" by the end of today from rains and maybe another half inch over the next couple days. This will depend on how the ULL tracks but may even see some convective activity, pop-up storms, across the area from some really cold temps aloft and if any place can break out into some sun and try to warm the surface this seems like a real good possibility if there are no breaks in sun looks like we could just get scattered showers.

Stay warm!

Another 3/4" in the bucket so far with plenty more to come, Gfs is close to some mangled flakes with surface in the mid 30s and 850 mb temps dropping down to -8c, won't happen here but north/elevation "may" see some flakes..
