Posted 6:45 AM Saturday - Things are looking colder for Tuesday's storm...meaning a better chance for snow. Low pressure will slam into the west coast later today and Sunday and then traverse the county, arriving in the Northeast Tuesday. Initially, a few days ago, this thing was forecast to really wind up, and draw warmer air northward, causing snow to mix with rain. The trend over the past 24 hours has been for the air to stay cold enough for primarily snow with a little sleet mixing in. Forecast temperatures up at 5000 feet had been getting up to freezing or even a bit above, now the temperatures are just a bit below freezing. At this point I would think some sleet could mix in.
One thing too. There's not much blocking to our north and east, to keep this thing around long. It should steadily move through which will keep accumulations in check. One thing for sure, some cold air is forecast to drop south from Canada, if only for a day or so, could really drop temperatures Wednesday and Thursday in particular. Boy, for as mild and rainy as this month started, it sure looks like it will end up cold and snowy. I guess this is the foundation being put down for our cold and snowy March predicted in our Spring outlook.
