DAYS 1-5 (MARCH 19-23)
The final full day of winter will have a bit of a spring feel to it as we are still on the milder side today with showery weather. There is a frontal boundary though that will sit over the region, keeping northern MA and southern NH a little cooler for a good part of the day. Along with the showery episodes, triggered by a broad low pressure area moving into the Northeast, we’ll also see areas of fog. One of the impulses coming along later today and this evening will make the atmosphere unstable enough for possible thunder. Once this goes by, we’ll get some drier air into the area overnight and Sunday as the low pressure circulation begins to move away. We welcome the arrival of spring with the Vernal Equinox at 11:33 a.m. Sunday, and the day, despite being breezy, will be fairly mild, as colder air is locked up behind a trough that won’t come through our region until the evening. This may trigger a quick rain shower, and it will introduce cooler air for the first couple full days of spring early in the week. Another cold front will deliver colder air to the region by late Tuesday and Wednesday, at which time we’ll start to see clouds advancing ahead of our next storm threat, which may start as snow for at least parts of the region as early as Wednesday evening. But that’s several days away so there’s plenty of time to focus on it later…

DAYS 6-10 (MARCH 24-28)
Low pressure impacts the region with what ultimately ends up as a rain event to start this period, and a follow up system brings a precipitation threat around mid period, but less certainty as to the character of that system. Drier weather takes over later in the period. Temperatures near to below normal.
DAYS 11-15 (MARCH 29 – APRIL 2)
The pattern in this time frame likely finds us in that previously-mentioned battle zone between Canadian cold and southeastern USA warmth, and I’m leaning toward the colder side winning out here, including additional precipitation threats which are obviously too far away to speculate much on.
