Weekly Outlook: February 24-March 1, 2020

As we approach the end of February, there’s something you’ll need this week, and it’s not a shovel – it’s an umbrella.

We actually start the week off with another dry and mild day thanks to high pressure, but you’d better enjoy it, because things go downhill for the rest of the week. Temperatures should get into the 50s again, possibly even topping 60 in spots, but along the coast, we may have a seabreeze develop in the afternoon (yes, you read that right). A weak cold front moves through at night, bringing temperatures back toward normal, but that sets the stage for the next few days.

That front will likely stall out south of New England and stay there on Tuesday. A weak wave of low pressure will ride along the front, bringing some showers to the region. They won’t be that heavy, and won’t be that widespread, so the day won’t be a washout. Across southern New Hampshire and the Merrimack Valley, we may have some cold air linger long enough that we get a little bit of freezing drizzle or maybe even a few wet snowflakes. Drizzle and fog linger for Tuesday night into Wednesday morning before the next storm system arrives.

Later Wednesday into Thursday, low pressure will move into the Great Lakes while a secondary area of low pressure develops near or just off the Mid-Atlantic coastline. This secondary low will spread some rain in for Wednesday afternoon and night, and some of it could be heavy. Once again, we may have some cold air in place across the Merrimack Valley, which could lead to a wintry mix or even some snow, but this is far from definite at this point. We’ll keep an eye on this over the next few days.

Depending on where you are and which model you believe, Thursday morning could be wet, white, or already drying out across the region. Images provided by Pivotal Weather.

That low in the Great Lakes swings a cold front through Thursday morning, bringing an end to the precipitation, and ushering cooler and drier air back into the region. High pressure then builds in with cold and dry conditions as we head into the end of the week and the weekend. The only exception could be across parts of Cape Cod and the Islands, where some ocean-effect snow is possible as colder air blows in over the relatively mild ocean.
