Lehigh Valley residents are waking up to several inches of snow Sunday morning as the latest winter storm to impact the region wraps up.
A winter weather advisory issued for the region has been extended until 10 a.m. The National Weather Service issued a slight uptick in its snowfall projections early Sunday to 3-6 inches across the larger region, up from 2-4 inches.
By 8:30 a.m., snow largely moved out of the area, however, lingering snow showers are possible through noon.
Expect slippery road conditions to continue throughout the morning, with increasing winds leading to blowing snow that could reduce visibility, the weather service warns.
Snow began overspreading the Lehigh Valley around 8 p.m. Saturday and increased in intensity later in the night, leading to treacherous travel conditions.
Just before 1 a.m. Sunday, PennDOT announced it was reducing the speed limit to 45 mph on most major highways in the region, including Interstate 78, Route 22 and Route 33. As of 8:30 a.m., speed limit restrictions remain on the following highways:
Interstate 80 in Carbon and Monroe counties
Interstate 81 in Schuylkill County
Interstate 380 in Monroe County
Slick roads led to numerous crashes. A vehicle rollover was reported on Airport Road at Locust Road in East Allen Township and a vehicle hit a pole on Uhler Road and East Braden Boulevard in Forks Township, according to the Northampton County Emergency Alerts Facebook page. On Route 191 in Plainfield Township, multiple vehicles were reported stuck.
The weather is also affecting mass transit in the region. LANTA bus service is operating under snow emergency routes, and LANtaVan service is limited to ADA and dialysis trips only.
With the snow moving out, high winds and bitter cold is moving in. Wind gusts are expected to increase to 30 mph by Sunday night, leading to continued drifting of snow, according to the weather service.
Temperatures on Sunday will stay in the upper 20s, well below freezing, and overnight lows will dip into the low teens, according to the weather service. Combined with the high winds, wind chill values overnight will drop as low as zero in the Lehigh Valley and -10 in the highest elevations of the Poconos.
