An intense ocean storm continues to gain strength as it moves eastward this morning. The map above shows how much snow I expect to fall from about 10 AM until the snow ends. You can add these amounts to what you have on the ground. New England is on the western edge of the snow shield and there is often a sharp cut-off line between who gets snow and who doesn't get much. The heavier accumulating snow has been confined east of Worcester in this storm. The accumulating snow has ended for nearly everyone except parts of the south shore, Cape Cod and outer Cape Ann. morning storm of clouds.gifThe satellite loop shows the storm pulling out to sea this morning. Drier air is trying to work into the system and will keep this from becoming more than a light to moderate snowstorm for most of the area. I'll be updating the forecast all day on Twitter at @growingwisdom please send me your reports there.

A quick look at temperatures this morning shows a nice contrast here in eastern Massachusetts. This has helped a snow band set up from about Newburyport to Boston to Providence. Since this band has been sitting in place the past couple of hours those areas will end up on the higher, not lower end of my snow totals.

Here is a radar map of how thing stand as of mid-morning. Notice the heaviest bands are located right along the coast.

The map below shows potential accumulations in the various areas of the state. Notice southeastern Massachusetts and Cape Cod are forecast to get the most snow, but even there this is not going to be a blockbuster event. What will be noteworthy today are the winds which will be especially strong along the coast. At times some coastal areas south of Boston could see wind gusts hit 50 miles per hour. If the visibility falls to under ¼ mile and that happens with those winds some spots may see blizzard like conditions for a brief time. The most likely spots for this would be on a line from New Bedford to Osterville to Dennis Port to Harwich Port and perhaps extending to Chatham. The drier air being pulled into this storm is concerning me. If the dry air ends up moving in faster than forecast then snow totals on the Cape will be significantly under what I am forecasting. At the very least, I am leaning towards the lower end of the range in this area.

Wind and cold
Temperatures in the teens and 20s combined with the strong winds will make it feel very cold today. As you go outside to clean-up whatever snow does fall, just be sure to remember to bundle up. After all the mild air of last week, this will be a bit of shock. Winds are coming from a land direction, so although the winds are strong, they are not going to create any issues with coastal flooding.

After the storm passes, a cold President's day is followed by a milder Tuesday with some rain, especially at night. Temperatures Monday will struggle to hit freezing, while Tuesday afternoon, several spots will near 50°F. The rest of the week looks dry and chilly with some slow melting in the afternoons and hard freezes at night.

Gardening this week
This week I have a video on one of the easiest plants you can grow. The jade plant is one of those houseplants that is almost foolproof. Spend a few minutes learning more about this minimal care plant.
