Active weather continued for parts of the East on Friday, while rain spread across the Northwest.

A strong low pressure system over the Great Lakes slowly advanced eastward and pushed a front into the Northeast. This kicked up thunderstorm activity with heavy rains and strong winds from Pennsylvania to Maine. Rainfall totals surpassed 2 inches in parts of Pennsylvania in the early morning hours.

A midday total of 3.61 inches of rain was reported at Mt. Pocono. Behind this system, lighter and more widespread showers persisted for the Upper Midwest and Midwest. Strong winds also continued along the back side of this system with gusts from 40 to 50 mph across the Northern Plains and Upper Midwest.

Yankton, S.D. reported 51 mph wind gusts in the early morning hours. Severe storm development has not been reported across the Midwest or Northeast on Friday, but the system has a history of large hail, heavy rainfall, and damaging winds.

Meanwhile in the West, a low pressure system over British Columbia created a cold front that moved through the Pacific Northwest. This system pulled in moisture from the Pacific Ocean and allowed for scattered rain showers to develop, which turned to snow at high elevations of the Cascades.

Precipitation from this system advanced eastward into the Intermountain West as the system moved eastward throughout the day.
