NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Mount Holly New Jersey 
951 PM EDT Wednesday Oct 22 2014 


Synopsis... 
an area of low pressure offshore will continue to strengthen as it 
slowly tracks northeastward overnight. This storm system should 
be off the New England coast later Thursday into Friday, then move 
into Nova Scotia Friday night. High pressure is forecast to build 
toward our area from the southwest Friday and Saturday, then a 
cold front is expected to move through Saturday night. High 
pressure builds in for later Sunday and Monday before shifting 
offshore Tuesday. 


&& 


Near term /until 6 am Thursday morning/... 
the middle level low was centered over the waters off Delaware-Maryland-Virginia this 
evening. It should lift northeastward to the waters off New 
Jersey and Long Island toward morning. Meanwhile, the surface low 
was centered about 150 miles off the Delaware coast. That feature 
is expected to drift about 50 miles to the east during the course 
of the night. 


It will remain overcast and chilly in our region overnight. Low 
temperatures are anticipated to be mainly in the 40s. The wind 
should back from the north to the northwest at speeds around 10 to 
15 miles per hour with gusts into the 20s. 


Rain rotating around the coastal system will maintain a northeast 
to southwest orientation in our region overnight. Sometimes the 
rain will come down a little heavier than at other times, but most 
of this precipitation is still expected to lift north of our area 
during the late overnight perioe. Rainfall amounts over the entire 
County Warning Area should be in the quarter to half inch range, with lesser 
amounts possible in the southern poconoes...and western Berks County. 


&& 


Short term /6 am Thursday morning through 6 PM Thursday/... 
the middle level low and the surface low are forecast to move toward 
the waters off Cape Cod on Thursday. The precipitation associated 
with the coastal system will begin to lift northeastward, as well. 


We are expecting the rain to become showery and end gradually from 
southwest to northeast on Thursday. 


The sky should remain cloudy with a northwest wind in the 10 to 20 
miles per hour range with gusts of 20 to 30 miles per hour. The clouds and the northwest 
flow will likely keep temperatures from getting above the 50s on 
Thursday afternoon. 


&& 


Long term /Thursday night through Wednesday/... 
model consensus through the first couple days of the extended is 
pretty good, but once you get past Saturday a much larger spread is 
seen. We will, however, be transitioning from troughiness to degrees 
of ridging through the extended, starting by early next week. For 
the most part we maintain a relatively dry longterm from Saturday 
Onward as ridging begins to build to our south-southwest. 


Friday...upper level low continues to spin and pull away to our 
northeast with just some lingering backside showers possible across our 
northern zones. The overall trend on Friday is for drying as the 
strong pressure gradient and northwest winds remain in place. 
Temperatures should be able to rebound back in the low to middle-60s 
with less cloud cover than previous days and the lack of showers. 


Saturday and Sunday...high pressure builds to our south Saturday, 
however a strong short wave diving southeastward from the Great 
Lakes will dig another upper-level trough across the northeast later 
Saturday into Sunday. This will toss a cold front across our area 
Saturday night but still unsure if we will see a dry passage with 
this system. Thinking that the atmosphere will not have much time to 
modify ahead of the front and how much influence the energy will 
have as it comes in on the heels of the once cut-off low. With the 
limited amount of moisture expected it should result in a generally 
dry frontal passage. The associated surface low looks to intensify 
as is exits New England, which means a tightening pressure gradient 
down into the middle Atlantic Sunday. As a result, a breezy day may 
occur as mixing deepens. High pressure then starts to build in 
Sunday night. 


Monday - Wednesday...an upper-level ridge slides toward the east 
allowing high pressure to build across our area Monday before 
shifting offshore Tuesday. This is expected to result in warming 
conditions, especially as warm air advection develops Tuesday ahead of the next 
cold front. No major changes were made for this time frame, with 
just some blending in of the new 12z wpc guidance. 


&& 


Aviation /02z Thursday through Monday/... 
the following discussion is for kphl, kpne, kttn, kabe, krdg, kilg, 
kmiv, kacy and surrounding areas. 


Generally, MVFR ceilings are anticipated through tonight in our 
region. Periods of rain are expected, with some breaks in between. 


The ceilings are forecast to lift gradually into the VFR category 
from southwest to northeast on Thursday. The rain is anticipated to 
become more showery and it should end at our taf sites by middle to 
late afternoon. 


The wind shifted from north to northwest after sunset, and a 
northwest flow is expected overnight and Thursday. Sustained 
speeds are expected to be around 10 to 15 knots with gusts into 
the 20s or higher on Thursday. 


Outlook... 
Friday...VFR. Continued northwest winds with gusts around 20 knots. 
Some lingering showers possible north of Abe. Medium confidence, 
lower on showers. 


Saturday - Sunday...VFR. Winds shift to the west-southwest. Dry cold 
front passage expected late Saturday night. Medium confidence. 


Monday...VFR. 


&& 


Marine... 
the Gale Warning continues until 600 PM Thursday for our ocean 
waters and for the lower part of Delaware Bay. The circulation 
around the slow moving low off the coast should maintain a north 
to northwest wind over our waters with gusts of 35 to 40 knots 
anticipated. A Small Craft Advisory remains in place for the upper 
part of Delaware Bay. Gusts there should peak around 30 knots. 


Outlook... 
Friday - Saturday morning...Small Craft Advisory conditions persist, once the gales 
come down, as the coastal low pressure continues to move northeast 
though the pressure gradient should be relaxing by Friday night. 
Northwest winds around 15 to 20 knots. Medium confidence. 


Saturday...sub-sca. Westerly winds around 15 knots. Medium 
confidence. 


Sunday...period of Small Craft Advisory possible behind a passing cold front. Medium 
confidence. 


Monday...sub-sca. Medium confidence. 


&& 


Tides/coastal flooding... 
tides are running high due to a combination of the storm off the 
coast and the approaching new moon. High tides Wednesday evening 
peaked just at or slightly under minor flood levels along the 
ocean. The next high tide...Thursday morning around noon...will 
have a slightly higher astronomical component but winds will have 
a more pronounced northwest component which might help push water 
away from the coast. Right now the only flooding we/re expecting 
would be isolated minor flooding below our established thresholds 
needed for an advisory. However...we will be keeping an eye on the 
situation and issue additional statements as necessary. 


&& 


Phi watches/warnings/advisories... 
PA...none. 
New Jersey...none. 
Delaware...none. 
Maryland...none. 
Marine...Gale Warning until 6 PM EDT Thursday for anz431-450>455. 
Small Craft Advisory until 6 PM EDT Thursday for anz430.
