Cold front ends reign of mild weather

A cold front driving through the Philadelphia and New York City metropolitan areas will happen this week with periods of showers expected. The showers will mark the end of the warm regime of weather the past few days and begin the transition to a colder and stormier period of weather for this weekend.

The cold front will drive through the northern Mid Atlantic today with periods of showers. The showers will be capable of brief heavy downpours and wind gusts over 30 mph. Winds will veer from the southwest to northwest at 10 to 20 mph. Temperatures will rise into the mid to upper 60’s throughout the Philadelphia and New York City metropolitan areas ahead of the cold front before falling into the 50’s by late this afternoon.

Skies will clear tonight as the cold front exits and high pressure builds into the region. Scattered cloud cover is expected tomorrow. Winds will be from the northwest at 10 to 20 mph through tomorrow morning, decreasing to 5 to 15 mph by tomorrow afternoon. Low temperatures will range from the upper 30’s to lower 40’s over the interior and lower to mid 40’s along the coast. High temperatures will range from the mid to upper 50’s over the interior and upper 50’s along the coast.

Scattered cloud cover can be expected tomorrow night on through Friday afternoon with near perfect weather conditions for those going out for Halloween trick or treating. Winds will veer to the north at 5 to 15 mph. Low temperatures will range from the upper 20’s to lower 30’s over the interior, mid to upper 30’s over the western suburbs of Philadelphia and New York City, and upper 30’s to lower 40’s along the immediate coast and in urban areas. High temperatures will rise into the mid to upper 50’s throughout the Philadelphia and New York City metropolitan areas.

An area of low pressure organizing off the Mid Atlantic coast will produce increasing clouds on Friday evening with rain developing towards Saturday morning. The development and track of this low pressure system is very much uncertain, however those along the coast are more likely to be impacted by this storm on Saturday than over the interior. Periods of rain are expected through the day on Saturday with snow some mixing in at times, even along the coast. However, no snowfall accumulation is currently expected in any location. Winds will veer to the northeast at 15 to 25 mph with gusts over 30 mph at times. Low temperatures will range from the upper 30’s to lower 40’s over the interior and lower to mid 40’s along the coast.

The storm will exit on Saturday night with clearing skies through Sunday. Rather windy conditions can be expected with winds from the northwest at 15 to 25 mph with higher gusts. Low temperatures will range from the upper 20’s to lower 30’s over the interior and mid to upper 30’s along the coast. High temperatures will range from the mid to upper 40’s over the interior and upper 40’s to lower 50’s along the coast. The strong winds will produce wind chills in the 30’s and 40’s throughout the region.
