A weakening area of low pressure will pass to the north of the region this afternoon and evening. A cold front will pass through the area during this time, increasing the chances for some snow showers or flurries. Behind the frontal system, skies should clear as Arctic high pressure settles into the area to close out the weekend.
Temperatures will start out the forecast period below normal, however, a slow moderation is anticipated as we head into the early portions of the coming work week. The upward trend in temperatures will be augmented by the passage of warm front in the Monday night and Tuesday morning time frame, which should really help give the temperatures a boost as highs may reach well into the 40's by the midweek period. With the increase in temperatures will also come a proportional increase in the cloud cover and chance for precipitation. Rain should be the predominant precipitation type thanks to the warm air mass in place, though precipitation may start as snow on Monday night and Tuesday morning.
A respectably powerful storm is forecast to originate over the nation's heartland on Monday, and ride quickly north and east, through the upper Great Lakes on Tuesday, to a position south and east of James' Bay in Canada by Wednesday morning. This track would bring the system's cold front through the region during the day on Wednesday.
The end of the work week should feature a return to more seasonable temperatures, and precipitation should change from rain back to snow as several disturbances, each reinforcing the colder airmass behind the main cold front, sweep through the region through next weekend.
