Are you ready for the arrival of winter? It is coming. This week.
We have a preview Sunday night into early Monday. A weak system, with some moisture drawn north from the SW cutoff low, will bring us some light rain, changing to light snow. Up to 1” can be expected in the valleys and 2” on the ridges. This will primarily be on the grass, trees, cars, etc. The roads should stay mainly wet, esp. in the valleys.
Light snow ends Monday morning, followed by some increasing sunshine. The next storm, that SW cutoff, will then move into our area on Tuesday. This should be a cold soaking rain of around .75 to 1”. This rain will end Tuesday night leaving us with lots of clouds for Wed. Some sunshine is possible before the next system moves in.
“Winter” arrives Thursday. Now this system is a little different than I originally thought. Instead of a strong blizzard/severe weather producing low in the Great Lakes, it looks like we will have a wave developing on the strong front enhancing precipitation as it moves NE into our area. This would help pull the arctic air in changing the rain to snow in most areas. This storm could deepen dramatically in SE Canada, producing strong gusty winds with flurries and snow showers. Highs on Friday and Saturday will only be in the 20s.
Now for the speculation: an intriguing winter storm may be brewing for Dec 11/12/13. More information in the coming days. See maps below for pictures concerning Sun night/Mon and Thu's systems.
