The mid-day model runs are suggesting that tomorrow could be a little more wintry than thought. It still isn’t expected to be a big event, but with rain changing to snow and falling temperatures during the day, things could be pretty slick quickly in the morning. The National Weather Service has not issued any advisories yet, but I expect that to change this afternoon.
In a little more detail, enjoy this afternoon’s mild temperatures because this may be the warmest day for awhile. A cold front will cross the area overnight and a wave of low pressure will ride along the front bringing rain that starts around midnight. Once the front crosses the area, temperatures will fall and eventually change the rain to snow. I am expecting that sometime around sunrise. Temperatures will continuing falling through the morning, and since roads will likely not be pre-treated, quickly deteriorating conditions are possible during the morning commute. Overall, I think most of us will see a general 1 – 3″ accumulation, depending on how soon we change to snow, and then it’s going to be darn cold around here at least through the weekend.
As of now, the Friday night system is well south and not expected to result in anything more than partly cloudy. I’ll update again tonight around 10PM with any changes for tomorrow.
