An early-season off lake squall dumped a foot of snow on the city in the early morning hours Tuesday.
By daybreak the intense snow streamer had shifted east, impacting north and eastern Lambton County through Tuesday afternoon.
Environment Canada ended its snow squall warning for Sarnia and west Lambton County by noon, and its warning for areas to the north and east was lifted just after 3 p.m.
Meteorologist Mark Schuster expected flurries and local snow squalls to move out of the region by late afternoon.

"It's possible that some portions of Lambton County, generally just to the east of Sarnia can see as much as 20 to 30 centimetres of snow," said Schuster.
He said local blowing snow would reduce visibility to near zero at times making travel hazardous in areas impacted by lake effect snow.
The City of Sarnia declared a "Significant Weather Event" warning residents about snow-packed streets and sidewalks and asking that they not park on city streets to allow for snow plowing. City council decided this year to extend on-street parking to the end of November.
Morning buses in all zones, 1 through 8, were cancelled Tuesday as well as classes at Lambton College and various other events. For the full list of closures click here.
Sarnia Transit reduced its service on Tuesday due to the weather and started slower than usual. There was no morning service in Bright’s Grove and limited service in the Village of Point Edward. Service to some side streets including in the Mitton Street and Rosedale Avenue areas will be slower than usual. Check twitter, @SarniaTransit for updates.
OPP advised motorists to stay off the roads unless absolutely necessary. West Region OPP said within 12 hours officers responded to over 200 collisions. No serious injuries were reported in any of those crashes.
