Good Monday to one and all and welcome to the last week of 2011. It’s hard to believe we are about to wrap up another year and the year looks to be ending on an active note. That’s a fitting way to finish out a hyper active weather year across our region.

A storm system is gaining strength to our southwest today and will roll our way later tonight into Tuesday. The track of this low is one that will bring rain to snow across our part of the world as the storm passes by just to our south and east. The models show this very well…

Here’s a breakdown…

– Rain arrives overnight with locally heavy downpours likely through Tuesday morning.

– The storm deepens and pulls in colder air from the north and west and will result in rain mixing with and changing to wet snow during the afternoon and evening.

– A light accumulation will be possible across most of the region. I will also be watching for what’s known as a ‘deformation zone’ working across the area on the backside of the low. That could mean a band of heavier snow for some.

– Temps will hit the mid 20s by Wednesday morning and that mean some slick spots may develop on area roads. Some leftover snow showers or flurries should be around to start the day… especially in the east. 

– There will be a couple of weak systems diving in from the northwest later this week. These may try to bring something light our way.

– The models continue to point to a big buckle in the jet stream to begin the new year and this should mean a shot of cold and snow.

I will have another update later today. Have a great Monday and take care.
