| Area Forecast Discussion National Weather Service Mount Holly NJ 239pm EDT Sat Oct 3 2026 .WHAT HAS CHANGED... Small Craft Advisory issued for coastal waters off of New Jersey. Updated Aviation discussion for 18Z TAF update. .KEY MESSAGES... 1. Showers are expected to impact portions of the region Sunday and Sunday night. 2. Canadian high pressure will bring much cooler temperatures and dry weather through much of the week. KEY MESSAGE 1...Showers are expected to impact portions of the region Sunday and Sunday night. Low pressure developing along the stalled frontal boundary to our south Sunday and Sunday night will provide another round of showers across portions of the region. The timing of the showers will be focused during the afternoon hours Sunday, but could begin near/south of Philly in the morning and linger area wide into the evening or overnight hours. Probability of Precipitation has retreated slightly and now range from around 40-50% along and north of I-80 to around 50-60% within the I-95 corridor and Philly metro, to 60-70% across Delmarva and far southern New Jersey. The latest Quantitative Precipitation Forecast forecast has around 0.10" or less along the I-95 corridor and points north and west with around 0.25-0.75" across the southern Delmarva and far southern New Jersey. It's possible the showers don't make it much farther northwest than the I-95 corridor. There still remains spread in the guidance as to exactly how far north and west the showers will make it. Given overcast skies, easterly winds, and showers, temperatures Sunday will be cooler with highs likely only reaching the low to mid 60s in many areas. KEY MESSAGE 2...Canadian high pressure will bring much cooler temperatures and dry weather through much of the week. Canadian high pressure and a much cooler air mass will build into the region starting on Monday. Monday will feature mostly sunny skies with highs within a few degrees of 70, though a stiff northwest breeze will make it feel cooler. Sunny skies continue on Tuesday, though highs will only be in the upper 50s to mid 60s for much of the region which is upwards of 10 degrees below normal. Lows will fall mainly into the 40s, with 50s along the coast and the upper 30s in the Poconos. Some areas of frost will be possible mainly north of I-78 late Tuesday night into Wednesday morning. As cold advection wanes by mid-week, the airmass will begin to modify and trend warmer as southerly flow returns. Highs remain in the 60s on Wednesday, before warming back into the 70s again for Thursday and Friday. With high pressure remaining in control, mostly clear skies and dry weather is expected through the end of the week.
