Winter-Like Weather on the Way

By Steven DiMartino

Another warm start to the work week will give way to the arrival of winter-like temperatures as an Arctic cold front drives through the region on Wednesday. However, for the start of the week, mild Pacific high pressure will be in control leading to tranquil weather conditions.

Monday through Tuesday, high pressure will produce clear skies to scattered cloud cover. Winds will back to the southeast at 5 to 15 mph through Tuesday, increasing to 10 to 20 mph by Tuesday evening. Temperatures will average above normal through Tuesday. Temperatures Monday afternoon will rise into the upper 50s to lower 60s. Temperatures Tuesday morning will range from the mid to upper 30s. High temperatures Tuesday afternoon will rise into the lower to mid 60s.

An area of low pressure off the Florida coast this morning will lift northeast to around 300 miles off the New Jersey coast. This low-pressure system will slow the approach of the Arctic cold front on Wednesday with overcast skies and a few scattered showers. The Arctic cold front will drive through the Philadelphia area by Wednesday afternoon with additional showers. Winds will veer from the southeast to northwest at 10 to 20 mph with higher gusts in the afternoon and evening. Low temperatures on Wednesday morning will range from the mid to upper 40s. High temperatures ahead of the cold front will range from the mid 50s. Temperatures will fall into the 30s in the late afternoon and evening hours.

Arctic high pressure will be in place on Thursday with scattered cloud cover and much colder temperatures. Low temperatures will range from the mid to upper 20s. High temperatures will struggle into the mid 40s throughout the region.

A wave of low pressure will develop along the Arctic cold front on Friday morning producing snow showers over the interior. Some minor accumulations of snow is possible for elevations over 500 feet. Low temperatures will range from the mid to upper 20s. High temperatures will range from the lower to mid 40s throughout the region.

Arctic high pressure will be in control Friday evening on through Sunday with clear skies to scattered cloud cover. Temperatures will average well below normal for this time of year. Low temperatures will range from the lower to mid 20s. High temperatures will range from the upper 30s to lower 40s.
