BLOG: Ravens Weather Report
The only weather issue of concern this weekend will be with regard to an Alberta Clipper racing across the Great Lakes and into southern Quebec this afternoon. For our area, not much is expected however aside from a few flurries late this afternoon and early this evening in northern areas.
This will be of little impact to travel, and the good news is that with temperatures near 40 we will be able to melt much if not all of the crud we have on the ground in some of our northern and eastern communities. Sunday will feature some sunshine and temperatures once again in the upper 30s to near 40 but with cold advection ensuing Monday and high pressure moving overhead we will end relative mild spell and top out several degrees colder or in other words no better than freezing for many.
Big changes come Monday night and Tuesday when high pressure moves offshore and a storm system across the Ohio Valley draws warmer air northward. A second area of low pressure is expected to develop along the North Carolina coast or even just inland and move northeastward during the day as the primary low over the Ohio Valley weakens. What this will all add up to is a mix of snow and ice changing to rain early Tuesday with temperatures rising into the low to mid 40s. Obviously this scenario could change some over the next couple of days, but without a blocking high over southeast Canada and a southerly flow in the mid-levels a changeover to rain seems likely. The milder weather will be short-lived as a polar vortex dives southward through central Canada and sets up shop over Hudson Bay late this week and into next weekend.
Preliminary indications are that this polar low will carry the coldest air in quite some time into Quebec and Ontario... but can it make its' way into our viewing area? We'll see... but at the very least we should end up well below average late next week.
