NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Mount Holly New Jersey 
401 am EDT sun Apr 26 2015 


Synopsis... 
low pressure along the North Carolina coast will move out to sea 
today and merge into a large low pressure circulation near Nova 
Scotia early this week. Low pressure along the Gulf Coast Tuesday 
moves to the southeast United States coast Wednesday then 
intensifies northeastward Thursday. It becomes a large circulation 
Friday to the east of New England. Warmer high pressure spreads to 
our south next weekend. 


&& 


Near term /until 6 PM this evening/... 
low pressure offshore will continue to pull away while high 
pressure builds across the area. A dry day is expected with 
varying amounts of clouds. There will still be some clouds 
associated with the offshore low across the south this morning and 
then it should become sunny there later. Some daytime cumulus will 
develop across the region this afternoon. Winds will be mostly north 
or NE at 5 to 10 miles per hour. High temperatures will be a few degrees below 
normal...but mostly in the upper 50s or low 60s...so overall quite 
pleasant. 


&& 


Short term /6 PM this evening through 6 am Monday/... 
the fair weather will continue tonight. High pressure remain to the 
west while an upper trough will approach from the north. 
Overall...sky conditions will average partly cloudy. Temperatures 
will be milder than this morning with lows in the upper 30s north 
and low to middle 40s elsewhere. Winds will be light...mostly from the 
northwest. 


&& 


Long term /Monday through Saturday/... 
500 mb: colder than normal heights prevail here most of this 
forecast period with a large cyclonic circulation in the western 
Atlantic near Nova Scotia, dominating the flow here through Tuesday. 
Then a potentially complex interaction between the northern and 
southern streams may yield another closed low near Long Island by 
Friday. Ridging follows next weekend. 


Temperatures: calendar day averages around 5 degrees below normal 
Monday, maybe a few degrees below normal Tuesday then near normal 
Wednesday - Friday, with a definite warming trend to follow next 
weekend! 


The 12/25 naefs situational awareness table has nothing extreme for 
our forecast area the next 6 days. 


Hazards this 6 day period: fire weather is the most likely consideration 
prior to next weekend. 


Forecast basis: unless otherwise noted, a 50 50 blend 00z/26 GFS/NAM 
MOS guidance Monday-Tuesday, 00z/26 mex MOS Tuesday night and 
Wednesday, then the 0521z/26 wpc gridded elements of maximum/min temp, 
12 hour pop, 6 hour dewpoint-sky-wind from Thursday through next 
Saturday. 




The dailies... 


Monday...breezy with northwest gusting 20-30 miles per hour during the day, 
diminishing at night. Considerable cloudiness during the day with 
scattered instability showers, mainly the daylight hours. 
Confidence: above average. 


Tuesday...partly sunny day, probably clearing at night. North-northwest wind 
gusting to 20 miles per hour during the day, diminishing at night. Confidence: 
above average. 


Wednesday...partly cloudy. Light west wind. Confidence: average 
except below average on the small chance of showers mentioned in 
the afternoon. 


Thursday...considerable cloudiness with chance of a sprinkle or 
shower as the western lobe of the the Atlantic trough rotates southeastward 
overhead and tries to form a closed low. North to northeast wind 
gusting to 20 miles per hour during the day, possibly higher coast. Confidence: 
below average. 


A caveat for Thursday...there is a chance that the interaction of 
the northern and southern stream short waves may yet result in a 
strong rainy gale for our coast Thursday. 


Friday...partly cloudy to clear. Northwest wind gusting 20 to 25 miles per hour. 
Confidence: above average. 


Saturday...partly cloudy. Northwest wind. Confidence: above 
average. 00z/26 GFS MOS guidance. 




&& 


Aviation /08z Sunday through Thursday/... 
the following discussion is for kphl, kpne, kttn, kabe, krdg, 
kilg, kmiv, kacy and surrounding areas. 


Good flying weather is expected across the region today and tonight. 
A low pressure system is moving well south of the area while weak 
high pressure remain across our area. Clouds associated with the low 
will remain over the region before moving east. Clouds are of the 
middle variety across the Delaware-Maryland-Virginia and southern New Jersey with high clouds father 
north. Winds are mostly light northwest/west and they will turn NE after 
sunrise. Later today...a continuation of VFR with daytime cumulus scattered 
across the region. Winds mostly NE 5 to 10 knots. Tonight...VFR 
(mostly clear) with northwest winds 5 to 10 knots. 


Outlook... 
Monday...mainly VFR ceilings with scattered showers, mainly daylight hours. 
Northwest wind gusty 20-25 knots during the day diminishing at night. 
Confidence: above average. 


Tuesday...VFR scattered-broken at or above 5000 feet. North-northwest wind gusty 20 knots. 
Confidence: above average. 


Wednesday...VFR with scattered-broken at or above 5000 feet. Small chance of an 
afternoon shower. Light west wind. Confidence: average. 


Thursday...VFR ceilings with a chance of a shower, mainly daylight 
hours. North-NE wind gusty 20 knots. Confidence: average. Uncertainty 
exists regarding the potential of the developing ocean gale 
coming closer to the coast than now generally expected. 


&& 


Marine... 
not a bad day to be out on the waters. Winds and seas will be gentle 
with weak high pressure across the waters. Winds will mostly NE 
today and then turn more nwrly tonight. Winds speeds mostly under 10 
knots. Seas on the ocean mostly around 2 feet today and tonight 
and on the Bay 1 to 2 feet through the period. A few showers far S 
before dawn today...then dry the rest of today and tonight. 


Outlook... 
Monday...Small Craft Advisory may be needed for the nearshore waters during the 
afternoon and evening where it will be more unstable with northwest wind 
gusts near 25 knots along the nearest mile of the coast but less wind 
once away from The Dock. No Small Craft Advisory hazard yet. Confidence for a 
nearshore Small Craft Advisory is above average but not yet categorical. 


Tuesday through Wednesday...no marine headlines are anticipated. Northwest 
wind Tuesday gust to 20 knots and then a light wind Wednesday. 
Confidence: above average. 


Thursday...a Small Craft Advisory appears likely, especially the 
Atlantic waters where hazardous seas will probably exceed 5 feet 
off New Jersey and 7 feet east of Delaware. There is a small chance of 
gale force gusts and 13 feet seas. Confidence: below average due 
to the uncertainty regarding the size, strength and track of the 
northeastward moving coastal Carolina low. 


&& 


Fire weather... 
dry fuels and minimum afternoon rh's of 25 to 35 percent may necessitate 
statements for increased fire danger sometime between this 
afternoon and Tuesday afternoon. Winds today and Tuesday will be 
close to the needed criteria or just below. Rh's are marginal. 


&& 


Climate... 
rer lows yesterday 4/25/15 for kilg kacy krdg kabe and that 
information was posted yesterday. 


&& 


Phi watches/warnings/advisories... 
PA...frost advisory until 8 am EDT this morning for paz061-062-105.
