High pressure will continue to give way to an advancing cold front today which will lead to an increase in clouds through this afternoon. Winds will increase from the southwest around 5 to 10 mph with temperatures rising into the upper 50’s to mid 60’s for highs.
Tonight, the cold front over the central Great Lakes this morning will move through the Philadelphia and New York City metropolitan areas with scattered showers. The showers will be rather weak and will move through between late tonight and early tomorrow morning. Winds will shift to the west and northwest around 5 to 10 mph with temperatures falling back into the upper 30’s to mid 40’s for lows tonight.
High pressure will briefly take hold once again for tomorrow providing another round of tranquil weather conditions with light westerly winds. Temperatures will rebound into the lower to mid 60’s throughout the region, which is about normal for this time of year. However, by tomorrow night, clouds will rapidly increase as the first of several disturbances will approach the northern Mid Atlantic.
A warm front will approach but stall to the south of the region with scattered showers through the day. Temperatures will remain near normal for this time of year with lows in the mid 40’s to lower 50’s and highs in the lower to mid 60’s. The low pressure system associated with the warm front will move through central New Jersey and to the south of Long Island on Thursday with periods of rainfall. Some snow may mix in for the highest elevations over northeastern Pennsylvania and northwestern New Jersey as the low pressure system exits, however no accumulation is expected. Temperatures will struggle in the mid to upper 50’s over the interior and lower to mid 60’s along the coast for highs.
A break in the rainfall can be expected on Friday as high pressure briefly builds into the region. Temperatures will be much cooler, averaging below normal for this time of year with lows in the upper 30’s to upper 40’s and highs in the upper 40’s to upper 50’s.
Another low pressure system will approach on Friday night and pass to the southeast of the New Jersey coast on Saturday with periods of moderate to heavy rainfall. Once again, the elevations above 1,500 feet will have a chance for some snow to mix in with the rainfall, but no accumulation is expected. Temperatures will be very chilly with lows in the lower 40’s to lower 50’s and highs in the upper 40’s to upper 50’s. The warmest conditions will be along the immediate coast.
