Stormy Conditions in Malvern Over Next Several Days

By Steven DiMartino

As a strong disturbance in the Ohio River Valley dives towards the Delaware and New Jersey coast Tuesday, a coastal low-pressure system is expected to develop by Tuesday afternoon leading to periods of showers. This coastal low will linger over the Philadelphia area Tuesday night on through Thursday, producing periods of rain and windy conditions. A tranquil weather pattern will return just in time for the weekend.

An area of low pressure over the Great Lakes and a strong disturbance over the Ohio River Valley will transition towards the New Jersey coast today on through tomorrow. Periods of showers can be expected as the new low-pressure system organizes east of the southern New Jersey coast. The showers will feature heavy downpours at times. Winds will back from the south to the northeast at 5 to 15 mph, increasing to 10 to 20 mph by Wednesday morning. Temperatures Tuesday afternoon will rise into the upper 50s to lower 60s over the interior and mid to upper 60s along the coast. Temperatures Tuesday night will fall into the mid to upper 40s. Temperatures Wednesday afternoon will range from the upper 50s to lower 60s throughout the Philadelphia area.

Periods of rain can be expected Wednesday night on through Thursday. Rainfall amounts will range from 0.25” to 0.50” for the western Suburbs of Philadelphia; and 0.50” to 1.50” for northeastern Pennsylvania. Winds will back from the northeast to northwest at 15 to 25 mph with higher gusts. Localized flash flooding will be a threat, along with minor to moderate coastal flooding. Low temperatures on Thursday will range from the mid 40s over the interior and upper 40s to lower 50s along the coast. High temperatures will range from the upper 50s to lower 60s throughout the Philadelphia region.

Showers will linger on Friday as the low-pressure system exits with improving conditions from west to east. Skies will clear by Friday evening as high pressure takes control. High pressure will remain in control through Monday with comfortable and tranquil weather conditions. Low temperatures will range from the lower to mid 40s over the interior and upper 40s to lower 50s along the coast. High temperatures will range from the lower to mid 60s over the interior and mid to upper 60s along the coast.
