7Weather – Boston hit 100º on Sunday, breaking the previous record of 98º set in 1933. We don’t have to go too far back to find the last triple-digit day. Logan Airport reached 100º last summer on June 30th.
Boston has reached 100º+ 27 times (including today) in 150 years of record. This puts the one-day average at 100º+ every 6 years. If you look at the last 30 years, it’s more common. We have hit 100º+ 6 times in the past 30 years, bringing this average to 100º+ one day every 5 years.
A heat advisory is in effect for Monday. It will be less hot, but more humid. Highs will be in the low 90s, but with the tropical air it will feel like the mid to upper 90s.
Once again we have the ingredients to disperse strong to severe storms in New England. The “light” risk in yellow below includes CT, RI, MA and parts of NH and ME. The main concern with these storms will be straight line wind damage, but we cannot rule out rotating storms.
If we stay mostly dry in the morning, our chances of stronger thunderstorms increase.
Departure times will be between 12pm and 2pm for southern NH and northern Worcester County, between 2pm and 4pm for Merrimack Valley and between 4pm and 5pm within I-495. If the storms continue, they will arrive in SE Mass between 6 and 8 p.m.
These storms erupt in front of a cold front. This front is bringing the humidity down on Tuesday and likely getting us out of this heat wave we are in. Wednesday also has low humidity and highs in the mid to above 80s.
