DAYS 1-5 (MARCH 14-18)

An area of high pressure offshore to our east today starts our next week with fair and milder weather. Some cloudiness will be rolling across the sky especially this morning and maybe some more in parts of the region later in the day in response to this warmer air moving in, but we will stay rain-free. Tuesday, a cold front trailing a weak low pressure area passing to our north will drop southward during the afternoon and evening and then another small wave of low pressure will ride along that frontal boundary as it sits over our South Coast region at night. This means dry and mild weather but with clouds moving in during the day, then cooler weather with a period or two of rain at night, but it may be just cold enough so that this rain can mix with some wet snow across southern NH, although if that does happen I’m expecting no accumulation. That little low pressure wave will have exited by early Wednesday, but it will serve to push that frontal boundary to the south a bit more and result in slightly cooler but fair weather conditions. Thursday, St. Patrick’s Day, may end up featuring weather somewhat similar to what Ireland frequently is like as an area of low pressure passing by to the south gets close enough to induce an onshore wind with lots of clouds, cooler air, and some damp weather as some rain may reach us from that low and/or some drizzle may develop from the onshore air flow, especially in coastal locations. If that low is a bit further south, we stay dry and just see some clouds. Friday, that low is moving away while another low pressure area heads from the Midwest into the Great Lakes and tries to drag it’s warm front across our area. If this happens, we warm up nicely that day. However, at this time of year these fronts can have difficulty moving fully through the region, and depending on how strong that departed low is offshore, and how much a little nose of high pressure from eastern Canada can push southward, at least parts of our region could end up much cooler than a lot of computer guidance and some forecasts currently advertise. For the moment, my leaning is for the cooler scenario, but with most rainfall from that Great Lakes low pressure area staying away for the daytime hours.

FRIDAY: Variably cloudy. Highs 53-60 southern NH and northern MA as well as South Coast, 61-68 in between these areas. Wind variable up to 10 MPH.

DAYS 6-10 (MARCH 19-23)

Low pressure passing to north brings a frontal boundary through the region with a chance of rain showers early March 19 followed by drier and cooler weather for the balance of the weekend of March 19-20, with the vernal equinox occurring at 11:33 a.m. on Sunday March 20. Another unsettled weather system is possible with passing low pressure later in the period.

DAYS 11-15 (MARCH 24-28)

We’ll sit in a battle zone between southeastern USA warmth and Canadian cold, leaving us vulnerable to a couple episodes of unsettled weather late in the month.
