Happy Mother’s Day to any mom reading this!

DAYS 1-5 (MAY 13-17)
It’s all about the wind direction, and it doesn’t even have to be a strong wind. Just this light wind off the Atlantic is holding the low level moisture in much of the area, especially coastal NH, eastern MA, RI, and eastern CT. With a little less of this influence to the northwest, interior southern NH and north central MA stand a better chance at seeing a little sun today. By Monday, the wind will turn more to the south and finally the low cloudiness will erode during the day, and by Tuesday it’s a taste of summer across the region with a southwesterly air flow, although this means the South Coast will be cooler. A cold front will approach Tuesday and may set off a few showers and thunderstorms mainly in areas north and west of Boston, and then this boundary will sit around the region at midweek providing an avenue for additional moisture, so we’re looking at an unsettled stretch of weather at that time. Forecast details…
TODAY: Mainly cloudy but partial sun possible north central MA and interior southern NH. Highs 55-60 immediate coast, 60-65 elsewhere. Wind E up to 10 MPH.
TONIGHT: Mostly cloudy. Patchy fog. Lows 46-53. Wind SE under 10 MPH.
MONDAY: Mostly cloudy into late morning then clearing midday and afternoon. Highs 58-65 coast, 66-73 interior. Wind S up to 10 MPH.
MONDAY NIGHT: Partly cloudy. Lows 52-59. Wind SW up to 10 MPH.
TUESDAY: Partly sunny. Chance of showers and thunderstorms midday through late afternoon, best chance north and west of Boston. Highs 68-75 South Coast, 76-84 elsewhere. Wind SW 10-20 MPH.
WEDNESDAY & THURSDAY: Episodes of showers. Lows in the 50s. Highs in the 60s.

DAYS 6-10 (MAY 18-22)
With the weather pattern likely putting southern New England in a zone between cool Canadian air and warm air from the Mid Atlantic to Southeast US, episodes of unsettled weather are likely, but don’t cancel any plans as there will be stretches of nicer weather amidst it.

DAYS 11-15 (MAY 23-27)
With low confidence I say this period is much like the one before it.

  1. WEDNESDAY & THURSDAY: My days off. 😉

    Of course, even if I had the typical weekend off there would still be unsettled issues I suppose.

    Is a sunny, mild stretch just too much to ask this spring 2018?

    1. It’s too much to ask in about 9 out of 10 springs in New England. It’s just the way it is here. 🙂

    2. Haven’t we experienced a couple of sunny mild stretches thus far? I think it’s been an above average spring thus far.

      1. We have. This is one of the 1 out of 10’s. 😉

        It’s been a decent spring by New England standards. As of 3 days ago May at Boston was in the top 5 warmest (granted only 1/3 of the way through it but a good start).

        1. I don’t want HHH but I would like to stop having to turn on my heat overnights/early mornings. 😉

  2. TK – What will the conditions be across the pond for the Royal Wedding? Since I have to get up early for work anyway, I might as well watch. I believe coverage is at 4:00 am our time. 😀

    2. Good question. I don’t trust the GFS at all right now and I haven’t see any other guidance for over there but I’ll look at that as we go through the week.

  6. In the 1985 NBA Finals, Bird’s Celtics destroyed Magic’s Lakers in game 1 on Memorial Day, and thus was dubbed the Memorial Day massacre.

    Looks like today’s 12z GFS wishes to set up the weather version of the Memorial Day Massacre for eastern New England.

    1. I uninstalled from my phone and clicked on the above link.
      It did install it on my phone.
      You may have to allow installs from unknown sources from this site.

      Good luck.

  8. Will see tomorrow if the SPC puts western parts of SNE in a marginal or slight risk tomorrow. Looking at the 12z runs of the NAM and GFS certainly parameters there for strong to possibly severe storms in those areas.

      2. Who lives at Logan? We lament about that place where seagulls live and a few people work.

          1. That’s only true for airports that stick out in water on their own, or are at significant different elevations than the cities they represent. This is only a very small percentage of airports.

    The correct answer is D.

    1. Thanks, Longshot. When we visited Spokane to see Macs sister, we learned all Mt St Helens info. Amazing that about 10 years or so later that the ash was still on the side of the roads in Washington
