We have weather people. It looks like an interesting pattern shaping up across the region starting this evening. The rain is underway across Ontario and southern Quebec with between 50 and 100mm forecast. The culprit is a slow moving - moisture laden cold front to our west that is pushing strong southeast winds and plenty of Gulf of Mexico rain into our regions. The radar is showing waves of precipitation moving east - northeast across the region. Winds are forecast to increase as well especially along the south shore of the St. Lawrence River. Wind warnings are in effect in southern Quebec as well as central New York and the Green Mountains of Vermont. Look for winds gusts to 90km/h by daybreak and into early Wednesday morning. As the day progresses on Wednesday, colder air will work in behind the cold front and change any leftover rain to snow with a few centimetres possible in many locations. The threat will develop once again for lake effect snow off Lakes Erie and Ontario and the NWS has posted watches in those lakefront counties including Jefferson and Lewis.

Into the weekend an omega block will be setting up to our east with high pressure preventing systems from advancing eastward. As a matter of fact some computer models are picking up low pressure southeast of Nova Scotia and retrograding it back towards eastern Quebec. The possibility exists for some measurable snow this weekend even away from the lakes. I will have more on that as the week progresses. In the meantime expect abundant rainfall tonight with rain changing to snow tomorrow night and then colder with flurries into the weekend.
