Many areas to see 4 days of 90 degree heat

For those of you who hate the heat, Monday will be cooler with highs back near 80F. It’s been a cool spring for the most part and a 4 day heat wave is going to be a shock to the system. I am not a fan of the heat and humidity. I know some of you look forward to the 90 degree stuff, but for me I just keep looking to when it will end.

I’ll be updating the forecast throughout the heat wave on Twitter at @growingwisdom Please follow me there. Feel free to comment or ask questions too.

Yesterday’s showers and thunderstorms marked the leading edge of the heat and humidity. Now, high pressure off the coast will continue to provide a hot and muggy southwest flow of air for the next 4 days. This is a pattern more typical of July of August, not late May or early June.
Whenever we see this kind of pattern, there is the risk for pop-up showers and storms in the afternoon. Nearly all of you won’t see any shower activity, but there is a chance so I want to mention it.
Remember, heat waves are defined as three or more days in a row with the temperature reaching or exceeding 90 degrees. Not everyone is going to see a heat wave. Cape Cod, parts of the north shore of Massachusetts, the south coast and some higher elevations won’t hit 90°F in this pattern.
The ocean is still quite cool with temperatures in the 50s to near 60F. Any slight sea breeze will knock temperatures back several degrees at the coast. Being near the water will be the best place to be over the next 4 days.
Areas around Route 495 and in the Pioneer Valley will see the hottest temperatures during starting today and running through the weekend. Several towns including West Townsend, Fitchburg, Manchester, NH, Framingham, Concord and surrounding areas will hit the mid-90s Friday and Saturday. I expect 95°F or 96°F to be a common number in those areas.
On Monday a cold front will break the back of the heat and temperatures will begin their decline back towards more typical levels. We will have to watch how this front evolves as severe weather can be a problem after 3 or 4 days of heat.
If you are curious, the record high temperature in Boston for Thursday, Friday, Saturday, and Sunday is 96F. The years are different, but the number is the same. I think those numbers will stick.
Gardening this week
After moving plants around my yard the past several years because they keep getting bigger and bigger I decided to do a video about just how big some of those plants you see in the nursery will become. While they may only be a foot or two tall today, just wait a few years. Check out how big some of the more typical garden center trees and shrubs can grow. I would be interested in any stories you have from your own garden. Tweet me @growingwisdom
