NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Mount Holly New Jersey 
924 PM EST Thursday Mar 5 2015 


Synopsis... 
Arctic high pressure builds in overnight and Friday. The high 
will then settle to our south on Saturday. A weak low pressure 
system will track to our north late Sunday into Monday, pulling a 
cold front across our region on Monday. High pressure should then 
build into the area Tuesday into Wednesday, with the next cold 
front scheduled to arrive later Wednesday into Thursday. 


&& 


Near term /until 6 am Friday morning/... 
storm over: pns and rer's are posted. The pns for snow will 
further update overnight. 


Have raised temperatures overnight because of increased wind. 
Record lows still appear to have a good chance of occurring at 
kabe and krdg, provided late decoupling occurs near sunrise. 


The 18z NAM was much better at at attempting to depict the 
gustiness across the forecast area. The 00z NAM suggests wind 
gusts will increase 5 knots toward 06z before decoupling attempts to 
become more extensive around 09z. 


At 02z, the backedge of the thick high cloud deck was moving east 
of the Appalachians. 


Low temperatures tonight are blended met/mav and additionally for 
the east PA and nnj Countryside only, added the modeled GFS two 
meter temperatures. 


Wind chills are likely to fall to near zero across most of the 
region, with the Poconos seeing wind chills which may get close to 
advisory threshold for a few hours. Given the limited window and 
marginal values in terms of and advisory, will just continue 
mention in the severe weather potential statement. 


&& 


Short term /6 am Friday morning through 6 PM Friday/... 
sunny day with high pressure building in on Friday but still cold. 
Did go a touch warmer than mav/met given the cool daytime bias 
with snow cover. Other elements straight mav/met. Continued 
northwesterly winds under 10 miles per hour or so. 


&& 


Long term /Friday night through Thursday/... 
the overall synoptic setup is comprised of an upper-level trough 
from the Midwest to the northeast and middle Atlantic. As short wave 
energy moves through the flow, this feature should amplify a little 
for a time or two. This should eventually weaken as energy ejects 
across the Southern Plains late in the weekend and early next week, 
with a ridge potentially building off the southeastern U.S. Coast. 
This results in the upper-level flow turning more zonal next week. 
We used a model blend for Friday night through Sunday, then went 
with the 12z wpc guidance thereafter. We then made some adjustments 
after additional collaboration with our neighboring offices. 


For Friday night and Saturday...a short wave trough looks to slide 
across the area, however a dry airmass results in no precipitation. 
At the surface, high pressure builds over the area however its 
center slides to our south through Saturday. This will result in a 
gradual return flow being established and after a very cold start 
Saturday, some moderation is expected in the afternoon. 


For Sunday and Monday...a short wave is forecast to track near the 
Midwest and Great Lakes Sunday, then well to our north Monday. This 
will drive weak low pressure well to our north, however a cold front 
is forecast to move through during Monday. It appears that the 
moisture will be lacking with this feature as much of the lift 
occurs well to our north. There could be a snow shower though Sunday 
night into Monday across the far northwest. Otherwise, the airmass 
is forecast to continue to modify as the flow comes more from the 
west and not the north. 


For Tuesday and Wednesday...high pressure should shift to our east 
as a cold front moves across the Midwest and the Great Lakes. Low 
pressure appears to track well to our north once again, with a warm 
front lifting mostly to our northwest. While the flow looks fairly 
weak, enough warm air advection is expected to occur to allow for further 
moderation of the airmass with many areas getting into the lower 50s 
Wednesday afternoon. The cold front should be arriving late 
Wednesday, however given the track of the surface low and short wave 
aloft it also looks to be moisture starved. 


For Thursday...a weak surface high is anticipated to move across the 
area, while a frontal boundary is draped from near Maine to the 
Great Lakes then into the Central Plains. The airmass should be much 
milder with afternoon highs getting into the 50s. The ocean and 
Delaware Bay are cold and if there is light enough flow, then a 
cooling affect can be expected closer to the coast. 


&& 


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


Remainder of tonight...VFR ceilings become VFR clear from west to east 
between 3z and 6z. North-northwest wind gust around 20 knots 
diminishing toward sunrise. 


Friday...VFR clear with scattered-broken cirrus at or above 20000 feet late in the day. 
Light wind. 


Outlook... 
Friday night through Sunday...VFR overall. A weak system moving by 
later Saturday should result in more clouds, however any 
precipitation looks to stay to our north and west. 


Monday and Tuesday...VFR overall. A weak cold front moving through 
Monday should result in more clouds, however it appears that it 
moves through dry. 


&& 


Marine... 
extending the Small Craft Advisory along lower Delaware Bay through much of the 
night. We may need to add a short fuse Small Craft Advisory for upper Delaware Bay around 
05z? Small Craft Advisory continues along the altc coastal waters through the 
overnight hours. 


For Friday, winds and seas should remain below Small Craft Advisory criteria. 


Outlook... 
Friday night and Saturday...the conditions are expected to be 
below Small Craft Advisory criteria, however the winds will 
increase some from the west-southwest during Saturday. There is a 
chance for some light freezing spray Friday night and Saturday 
morning. 


Sunday through Tuesday...we are anticipating sub Small Craft 
Advisory conditions as a weak front moves through mainly during 
Monday. 


&& 


Climate... 
with a snow cover in place and another Arctic airmass settling 
into the region and radiational cooling occurring we have another 
chance for more record lows across the region.
