Area Forecast Discussion National Weather Service Mount Holly NJ 947 PM EDT Tue Apr 29 2025

SYNOPSIS
A cold front will move through the area later tonight into Wednesday morning as low pressure passes by to our north as it moves from Ontario through Quebec and then eventually into Atlantic Canada. High pressure briefly returns late Wednesday into Thursday. Another low pressure system tracks to our north on Friday with a cold front moving through by Saturday. High pressure starts to build in from the north and west by Sunday however an upper level low could then impact the area by early next week.

NEAR TERM /THROUGH WEDNESDAY/
As we go through tonight, a rather mild to warm night for the region ahead of a cold front although the cold front will be working its way across parts of the region overnight. An upper- level trough will pivot across the eastern Great Lakes and adjacent Canada, however the main forcing looks to track to our north. A cold front tied to this feature though will arrive in our area.

The earlier MCS which affected Western and Central PA has diminished to an area of clouds and showers as of 930PM. What is left of the activity is moving across the southern Poconos and northeast PA attm. The activity is becoming more disorganized but a few claps of thunder are possible thru midnight. More scattered showers are possible across NJ later tonight according to some mesoscale models. We have kept in some slight chc pops overnight in case these develop ahead of the cold front. Pop/Wx changes were recently performed and minor edits to temp/winds already done from earlier.

For Wednesday, we will be in a dry post frontal regime.
However, there is not much of a cold airmass behind the front, primarily a slight reduction in temperatures across the board as well as much lower dewpoints and lower relative humidity (see the Fire Weather section below for more fire weather details).
Any lingering clouds will clear out quickly in the morning, then another mostly sunny and warm day in expected. High temperatures are mainly in the 70s to low 80s. Northwest winds will be near 10-15 mph with some occasional gusts near 20-25 mph possible at times.

SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/
High pressure centered north of the area will continue to dominate our weather Wednesday night through Thursday leading to mainly dry conditions. Wednesday night should be mainly clear with a mix of sun and clouds to follow for Thursday. Expect lows Wednesday night mainly in the 40s to low 50s with some 30s over the southern Poconos into parts of NW NJ. For Thursday, most inland areas (except the Pocono Plateau) will see seasonably warm temperatures with highs in the 70s. However an onshore flow from the southeast will keep it cooler for coastal counties with highs for these area mainly in the 60s.

For Thursday night through Friday, the next area of low pressure will advance northward from the midwestern states into the Great Lakes region and then on through Ontario towards Quebec. This will push a warm front through overnight Thursday night with warmer and more humid weather to follow by Friday as the flow becomes southwesterly. Generally expect highs Friday in the 80s except low to mid 70s right near the coast and over the southern Poconos. The day will also feature a bit more in the way of cloud cover compared to Thursday with the potential for some showers and storms to develop in the afternoon ahead of an approaching cold front.

LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/
A cold front moves into the area Friday night into early Saturday while at the same time a vigorous upper level disturbance rounds the base of the long wave trough over the east. Indications are that this may result in an area of low pressure developing in our general vicinity by early Saturday and this could slow the front down and keep things unsettled with periods of rain/showers lasting at least through Saturday morning and potentially right through the day. This will depend, however, on the speed of the front and the evolution of the low and this is still a bit uncertain.

For the latter half of the weekend into early next week, there is growing uncertainty regarding how the upper level pattern evolves. The trough over the east is likely to close off into a slow moving upper level low but there is considerable spread in our forecast models in terms of where this occurs. The deterministic GFS has generally been more progressive and closes it off farther east over the Canadian Maritimes however some of the GEFS ensemble members along with the ECMWF are suggesting it will set up farther west. This latter solution would keep us unsettled. Given the uncertainty, we stayed close to the NBM (National Blend of Models) which keeps at least chances for showers in the forecast (POPs 20-30 percent) Sunday through Tuesday.
