DISCUSSION
KEY MESSAGE 1...Below normal temperatures continue this weekend into early next week.
As low pressure moves into the Canadian Maritimes this weekend and high pressure builds to our west, northwesterly flow will continue to usher in cold air into the region. This will keep temperatures slightly below normal through the weekend into early next week. Early morning clouds have kept temperatures much warmer than expected, so canceled freeze warning and frost advisory soon. Growing season ends per regional agreements on November 15th, so this will be the last frost/freeze headline of the year. No further will be issued by our office until Spring 2027.
In addition to the colder temperatures, winds will be gusty during the day due to a tight pressure gradient across the area through the weekend with winds gusts of 20-30 mph possible.
With the cold air and northwest flow, there will also be the possibility for some lake effect/lake enhanced snow or rain showers in the Poconos and higher elevations of Sussex County, New Jersey as well. Brief periods of reduced visibility are possible, but little to no accumulation is expected. Conditions are not favorable for any snow squall development. Regardless, always reduce speed and turn on low beam headlights anytime it snows or visibility becomes reduced.
Temps gradually moderate as we head toward the middle of next week.
