ALLENTOWN, Pa. — The Lehigh Valley could experience a weather rollercoaster over the next several hours as a cold front approaches the region, bringing a medley of precipitation and thunderstorms.

Folks on Tuesday night can expect showers with the possibility of thunderstorms emerging after 2 a.m., according to National Weather Service in Mount Holly, New Jersey.

Some of those storms may pack a punch, with gusty winds and heavy rainfall likely. The temperature will dip to around 65 degrees.

The chance of precipitation is 90%, and new rainfall amounts are expected to range between one-tenth and one-quarter of an inch, although higher amounts could occur during thunderstorms.

As Wednesday dawns, the weather pattern is predicted to persist, with showers and thunderstorms expected to linger until about 2 p.m. Gusty winds and heavy rain remain on the menu.

The day's high will reach nearly 76 on Wednesday, and a calm wind may transition to a gentle breeze in the afternoon. The chance of precipitation remains at 80%, and new rainfall amounts between three-quarters and 1 inch are possible.

By Wednesday night, the atmosphere will settle down, but a chance of lingering showers and thunderstorms will persist until around 8 p.m. The sky will partially clear, and temperatures will drop to about 56 degrees.

According to the weather service, a north wind at around 5 mph will bring a touch of coolness to the air. The chance of precipitation diminishes to 30%, with new amounts expected to be less than a tenth of an inch, though thunderstorms may still bring higher accumulations.

As a cold front is expected to move offshore by late Wednesday, high pressure will then build in and maintain control through Sunday.

Looking ahead, another frontal system may approach early next week, keeping the weather patterns unpredictable.
