NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Mount Holly New Jersey 
308 PM EDT Friday Oct 31 2014 


Synopsis... 
a series of low pressure areas will organize off the middle Atlantic 
coast tonight through Saturday night...and finally move northeast 
into the Canadian Maritimes Sunday night. High pressure will move 
in from the west on Sunday and crest over the region on Monday. A 
warm front will cross the region on Tuesday followed by a cold front 
on Thursday. 


&& 


Near term /until 6 am Saturday morning/... 
through this afternoon...sprinkles may develop Monmouth/ocean 
counties...and become heavier showers toward 6 PM. We see an ob of 
sprinkles at kwri but unsure of it. 


Tonight...strong 180 M hfc associated with closed low aloft moving 
down into Georgia/SC early Saturday will permit considerable lift to 
develop in our area late as vorticity aloft stretches northward. 
Rain may be briefly heavy after midnight. Boundary layer appears 
too warm for snow and sleet in the Poconos. 


Gusty NE winds to 25 miles per hour develop Monmouth County coast after midnight. 


50 50 blended 12z NCEP MOS guidance but trended with the slightly 
warmer GFS mav dewpoints. 


&& 


Short term /6 am Saturday morning through 6 PM Saturday/... 
plenty of cyclonic moist inflow and rather unstable should wring 
out pretty decent periods of rain through the midday hours. Chilly. 


Noting large tt of nearly 55c and swi -1c and ki near 29c lower part 
of Delaware-Maryland-Virginia Saturday morning. Could be isolated thunder but not in 
grids. 


Temps: lowered the 50 50 blended 12z NCEP MOS guidance per the 
12z/31 European model (ecmwf) and the drier dewpoints filtering south during the 
afternoon. 


Gusty north winds 20-30 miles per hour...may gust 40 miles per hour nearest 2-5 miles of 
the coast but no Wind Advisory at this time. 


&& 


Long term /Saturday night through Friday/... 
the strongest gradient will likely be over the eastern half of 
the region Saturday night into early Sunday, however at this time 
the middle and upper level trough axis should be bisecting the 
region. Also a middle level inversion will limit mixing. Instead, the 
strongest winds likely Sunday afternoon into early Sunday evening 
when the tightest middle and upper level height gradient will be over 
the region. Also, 6 hour pressure rises through this period are 
forecast to be between 2 and 6 mb, while not nearly as impressive 
as the 10mb plus pressure rises well off the coast that the models 
show, it could be enough for a small component of an isallobaric 
wind. Having said all that however, based on local high wind 
guidance we still appear to be on the lower end of a Wind Advisory 
threat even along the coast. Therefore, will just keep mention in 
the severe weather potential statement at this time. 


Temperatures...in the wake of the cold front on Saturday, temperatures by 
Sunday should be 10 to 15 degrees below normal. The coldest 
weather is expected Sunday night with decreasing winds and 
clearing skies. Still expecting the vast majority of the region to 
be near or below freezing Sunday night. 


Precipitation...models are in much better agreement of the timing of the 
precip, which will mainly be during the day Saturday, with some 
lingering into Saturday night. Through this period, all of the 
region is expected to be well above freezing, so precipitation type is 
expected to be rain. From the model soundings, the melting layer 
through this period is forecast to be at or above 4000 feet above ground level. 
With such a deep warm layer, even flurries are very unlikely. 


Monday and Tuesday...surface high builds northeast as the upper 
level ridge slides over the region. Still expect a warming trend 
through this period due to both air mass modification and 
increasing thicknesses. However, interestingly, the GFS is now 
showing a much more dramatic warming trend through this period as 
compared to yesterdays runs, with highs in the upper 60s possible 
by Tuesday. 


Wednesday through Friday...still considerable uncertainty if the 
cold front that will approach from the west will stall west of the 
region until late Thursday when an upper level trough digs southeast 
toward the region. Given the uncertainty and model differences 
have stayed close to the previous forecast. 


&& 


Aviation /19z Friday through Wednesday/... 
the following discussion is for kphl, kpne, kttn, kabe, krdg, kilg, 
kmiv, kacy and surrounding areas. 


Rest of today...VFR ceilings overspreading at or above 3500 feet. Spotty MVFR 
ceilings in New Jersey. North to northeast wind gusts increasing to 15 knots late 
this afternoon. 


Tonight...ceilings lower to MVFR conds in periods of rain/drizzle. 
Chance of IFR conds in New Jersey. North-NE wind gusts 15-20 knots. Chance of a 
period of heavy rain after 05z/01. 


Saturday...MVFR ceilings expected across the region. Localized 
IFR conditions closer to the coast including kacy and kmiv and 
possibly back to kphl and kilg during the morning-midday in 
periods of heavier rain. Gusty north winds 20 to 30 knots. 


Outlook... 
Saturday night into Sunday...conditions will slowly improve from 
west to east. Breezy northerly and northwesterly winds expected 
especially near the coast. 


Monday through Tuesday...VFR conditions expected. 


&& 


Marine... 
tonight...Small Craft Advisory north-NE wind conditions develop but the headline is 
superseded by tomorrows Gale Warning. 


Saturday...gale conditions expected all waters by 6pm Saturday 
with various starting times. At this time it looks like marginal 
gale begins vicinity 44065 (nnj waters) near daybreak Saturday and 
then spreads southward during the day with gusts increasing 5 knots 
everywhere during the afternoon. We may see spotty gale gusts 
during the late morning even in Delaware Bay. 


Gale watch upper Delaware Bay changed to a warning at the 330 PM issuance. 


Outlook... 
Saturday night through Sunday night...gale conditions expected on 
the Atlantic waters and lower Delaware Bay with peak gusts near 45 
knots. Seas as high as 10ft possible on the Atlantic waters. On the 
upper Delaware Bay...Small Craft Advisory gusts expected primarily 
Saturday night into Sunday. 


Monday...conditions should fall below Small Craft Advisory criteria by Monday 
afternoon. 


Tuesday...winds and seas are expected to be below Small Craft Advisory criteria. 


&& 


Tides/coastal flooding... 
a strong northeast flow associated with the strengthening low 
pressure system off the East Coast will produce elevated water 
levels down the shore through the weekend. Current guidance suggests 
minor tidal flooding along both the New Jersey and Delaware coasts 
for Saturday afternoon/S high tide...and perhaps again at the time 
of high tide early Sunday morning. Total water levels (astronomical 
tide plus the positive anomalies caused by the storm) from Atlantic 
City south through Lewes Delaware have a good probability of being high 
enough during Saturday afternoon/S high tide to warrant an advisory 
statement...so one has been issued. Right now current guidance 
suggests that while minor tidal flooding is expected in 
Middlesex...Monmouth...and ocean counties...total water levels will 
peak just short of advisory level criteria. This could be a close 
call, so residents along the coast should keep abreast of updated 
forecasts and advisories as this event unfolds. 


Right now elevated water levels are also expected in the Delaware 
Bay, with pockets of minor tidal flooding possible at the time of 
high tide Saturday afternoon and evening up through Reedy Point. No 
flooding is expected at this time in the tidal portions of the 
Delaware River...including Philadelphia. 


No problems are currently expected along the shores of the 
Chesapeake Bay affecting the middle and upper portions of the 
Maryland Eastern Shore. 


&&

PA...none. 
New Jersey...coastal Flood Advisory from 1 PM to 7 PM EDT Saturday for 
njz022>025.
