If you're going to be driving late tonight, be careful.

With forecasters saying snow could fall at the rate of an inch per hour at times, driving conditions could begin to deteriorate by midnight.The National Weather Service has issued a winter storm warning for tonight into tomorrow morning for four-to-eight inches of snow in Carbon, Schuylkill, and Monroe Counties. AccuWeather, based at State College, has a slightly lower estimate of 3.3 inches.Some TV station meteorologists are predicting only one-to-four inches, with the four inches expected in the higher elevations.The accumulation certainly won't match the freak Halloween snowstorm on Oct. 30, when Summit Hill got over 13 inches of the white stuff.Forecasters say rain will fall until 8 or 9 p.m. today, and then change over to snow as a cold front drifts down from Canada.The snow will be accompanied by wind gusts up to 35 miles-per-hour. Little drifting is expected because it will be a heavier snow.If accumulation does exceed three or four inches, there is a threat of downed tree limbs because of the weight of the snow.The National Weather Service in Mount Holly, N.J. warned that untreated roads will become "exceedingly hazardous" toward midnight.Parking regulationsMunicipalities will be enforcing winter parking regulations, which in many towns is an odd-even arrangement throughout the town. If uncertain of the rules, check with your borough office.Joseph Fittos, chief of police in Summit Hill, said officers will be ticketing cars if three or more inches of snow falls and cars aren't removed from the odd-numbered side of the street.He said the ordinance requires that no parking is permitted on odd-numbered sides, once three inches of snow falls, between 8 a.m. and 6 p.m.Fittos said there is no parking on the even numbered side of the street the day following the clearing of the opposite side of the street.Violators will be ticketed with the fine being $25.Lehighton borough is trying a unique approach to winter parking. The borough has voluntary odd-even parking rules if four or more inches of snow is predicted.No tickets will be issued for those who don't comply, but police Sgt. Joseph Lawrence said it will help the borough work crew do a better job of plowing curb-to-curb if cars are moved.Lawrence said in years past, there was odd-even parking only on snow emergency routes. He said the voluntary measure this year is borough-wide.He said the suggestion for voluntary odd-even parking was reached in a committee meeting which was attended by police officers, borough workers, and some council members.Police will also be keeping a watch on alleys to assure cars aren't blocking them when plowing needs to be done.Mayor Donald Rehrig said a problem exists with people parking in alleys when it snows, making it difficult not only for plowing but for emergency vehicles to get through if needed.The snow, however, is good news for area ski resorts. Above-normal temperatures have kept ski resorts from opening around Thanksgiving as originally planned. The expected snow and cooler temperatures projected over the next few days will finally put their operations on a winter course.No additional precipitation is expected during the next week, say forecasters.Daytime high temperatures will be in the mid 30s tomorrow and about 40 on Friday, while overnight lows will be in the mid 20s through at least Monday night.
