DAYS 1-5 (MAY 31 – JUNE 4)
Memorial Day 2021. We’ve all been talking about the unseasonably chilly and wet weather that we’ve had the past few days after having a relatively very nice spring overall. We can complain about it or accept it, hate it or love it, but let’s all take some time to remember why we get to hide from the weather or face it head on. A big part of that reason are people who served us and paid the ultimate sacrifice, and will never get to walk in rain or sun again. Please remember them as you go about your day today….. As far as the weather, we’re not quite out of this yet, but you’ll see signs of improvement today as the most numerous of the lingering showers are occurring as I write this blog update, and are moving through eastern MA and southern NH. In fact, I just had a tiny but heavy downpour cross my location (about 7:40 a.m.). As a low pressure center cuts right across the region and then slowly exits via the Gulf of Maine by midday and afternoon, we’ll see less shower coverage, becoming just isolated, but there will still be enough instability left in the atmosphere that a shower or even isolated thunderstorm cannot be ruled out right up until the end of the day. Tonight, the drier air finally moves in behind the low for some clearing. This will mark the end of May and meteorological spring, having seen four chilly and fairly wet days, not very representative of meteorological spring overall, which was mild in general, and had significant amounts of dry weather despite some episodes of beneficial rainfall, helping our precipitation deficit get reduced. Meteorological summer arrives Tuesday, the first day of June, and we’ll immediately see a turn in the weather pattern that will put you in summer mode. While Tuesday will only be somewhat warmer, with at least partial sunshine and high temperatures over 70, it will feel quite different than the days preceding it. This trend will continue Wednesday with another warm day, but some clouds will increase later in the day and at night as a weak disturbance approaches. At this time I think the shower activity will hang back mostly to the west of the region at least during the day, but a couple may wander in sometime at night. With high pressure becoming established off the US East Coast toward Bermuda, and a frontal system trying to move into the region from the northwest, Thursday and Friday should be fairly warm and on the humid side, featuring more cloudiness, especially Friday, and some risk of showers and thunderstorms, weighted more toward Friday as it stands now.
TODAY (MEMORIAL DAY): Cloudy with areas of fog and numerous to scattered showers morning. Mostly cloudy with isolated showers and thunderstorms afternoon. Highs 56-63. Wind variable up to 10 MPH becoming W to NW 5-15 MPH during the day.
TONIGHT: Partly cloudy. Patches of fog forming. Lows 48-55. Wind NW under 10 MPH.
TUESDAY: Partly sunny. Highs 71-78. Wind SW 5-15 MPH.
TUESDAY NIGHT: Partly cloudy. Lows 55-62. Wind SW up to 10 MPH.
WEDNESDAY: Partly sunny. Highs 72-79. Wind SW 5-15 MPH.
WEDNESDAY NIGHT: Mostly cloudy. Chance of showers. Areas of fog. Lows 60-67. More humid with dew point near 60. Wind SW up to 10 MPH.
THURSDAY: Partly sunny. Chance of showers and possibly a thunderstorm. Highs 77-84. Humid – dew point 60+. Wind SW 5-15 MPH.
THURSDAY NIGHT: Variably cloudy. Chance of a shower. Patchy fog. Lows 60-67. Humid – dew point 60+. Wind SW under 10 MPH.
FRIDAY: Mostly cloudy. Chance of showers. Highs 73-80. Humid – dew point 60+. Wind SW 10-20 MPH.
DAYS 7-10 (JUNE 5-9)
High pressure will anchor off the US East Coast and probably keep that frontal boundary I talked about mostly to the west and north of the region. Weekend of June 5-6 sees some clouds to start then overall more sun both days with increased heat and moderate to borderline high humidity, but probably no rain threat other than possibly a shower to start out June 5. June 7-9 will see that frontal boundary closer at times with a few opportunities for showers/storms.
DAYS 11-15 (JUNE 10-14)
High pressure offshore should weaken, more of a zonal flow pattern arrives with variable temperatures and a few shower threats amidst mostly dry weather.
