Evening Storm Threat / How Hot This Week?

Good evening Woods Hill Weather readers! I hope you are enjoying this blog and getting useful info out of it. If you haven’t commented yet, please do so! You can use any name you like (keep it clean), and your email is needed only once for approval (nobody else will see it).

First, I’m going to address the storm threat that continues through the evening hours, then we’ll look ahead to the rest of the week to see how hot it may get and if there will be any other storms, and of course a peek at the weekend (it’s never too early to think about the weekend, is it?).

We have seen several bands of showers and a few thunderstorms roll through southern New England from NW to SE today. Strong to severe storms have been very limited, however, up to this point. Extensive cloud cover and rain-cooled air has prevented the atmosphere from becoming very unstable. However, with a frontal system still to our north, and having to move through the muggy and somewhat unstable air  mass in place, I cannot rule out thunderstorms until sometime between 8PM and 11PM from north to south across southern NH and eastern MA. There are storms in upstate NY and northern New England sinking to the S & SE. Some of these, or other storms that form, may make it down into southern New England during the next few hours. At this point I do not see a widespread outbreak of storms, but any storms that do make it down here will have the potential to produce heavy downpours, hail, strong and gusty winds, and frequent lightning. So be on the look-out for threatening weather approaching from the northwest or north. Once these storms push south or dissipate later tonight, we should be quiet in terms of storms during the overnight hours.

With the boundary hanging around over far southern New England Tuesday and a little moisture in the air, I can’t rule out a few pop up showers and storms on Tuesday. Most areas will see nothing, with just a mostly sunny to partly cloudy, very warm, and moderately humid day. High pressure will build over the area at all levels of the atmosphere Wednesday with a sunny, warm to hot day, but not too humid. By Thursday and Friday, surface high pressure will build just off the East Coast and upper level high pressure remaining over New England will produce hazy, hot, and humid weather. Thunderstorms should be limited or not occur at all, despite the surface heat, because of very warm air aloft, which limits storms. There is always a slight risk of a pop up air mass thunderstorm in that kind of heat, though, but I will leave them out of the forecast for now.

By the time we get to Friday night or Saturday, a cold front should move through the region, taking the edge of the heat. The timing of this front will determine how hot Saturday is. This front may also produce some thunderstorms Friday night or Saturday. By Sunday, heat and humidity will be noticeably lower.

Detailed Boston Area Forecast…

TONIGHT: Variably cloudy. Isolated to scattered shower and thunderstorms mainly between 8PM & 11PM from north to south. Not all areas will see them. Areas that do may experience downpours, small hail, strong & gusty winds, and frequent lightning. Areas of ground fog after 11PM dissipating about dawn. Mild and muggy. Low 65 to 70. Wind NW 5 to 15 mph, except variable and possibly strong and gusty around any storms.

  1. Thank’s TK- I will take the heat over the cold anytime. Keep up the good work with this
    site.

    1. Thanks John. I had a time error on the discussion but it’s been fixed. Had the wrong time for the storm threat. Oops!

  2. I have noticed what appears to be a plume of smoke on the satellite loop, extending from a cluster of fires in south central Canada to western New England as of early this evening. This may cause a milky or hazy appearance to the sky later this evening, tonight, and part of tomorrow as it drifts ESE across New England. Some of the smoke may mix down low enough to result in a faint smell of smoke in the air to those with a good sense of smell.

    1. Interesting TK. Thanks

      Sun is out here and it’s really a lovely evening. We didn’t have enough rain to help the vegetation which is too bad.

      1. Some areas got pounded earlier. Around 11:50AM Reading got nailed. Rained so hard I could barely see across a parking lot. Woburn Mall parking lot was flooded about the same time. While here, just a few miles away, we had a 30-second downpour, a few light showers, and 0.03 inch rain.

  3. As I’m watching radar trends, I’m starting to think the threat of storms is rapidly diminishing, but we’ll not let our guard down for about 4 more hours, just in case.

  4. I’m thinking that we’re gonna get virtually nothing this evening at this point.

    Going for the Gretzky on Friday, eh? (and a Pavel Bure on Thursday) Don’t wanna pull the trigger on triple digits?

    1. I was thinking that as early as 7PM but I’m always leery of some outflow boundary that suddenly kicks off a “storm out of nowhere”, so I held the threat for a while.

      Yes, a Bure and a Gretzky are in my forecast at this point. I’m hesitant on the 100+ but if the wind is straight west on Friday, look out.

  5. Looking at the glass half full with the heat at least we are not talking a long stretch of 90 plus heat like they are dealing with in the Plains and parts of the upper Midwest.

  6. Nor sure if anyone saw but Oklahoma City has had 28 days straight of 100+. Now that is some serious heat!!

  7. O.M.G. Bri, Take about a flashback! The “keep it clean” comment shot me right back to 1983 and walking JP home down Montvale and you making that comment. I remember it like yesterday….I must be getting old.

    2. I wouldn’t call it “old”. How about “nicely aged”? 1983 was a great year. Loved the hot summer we had that year. Hit 100 on Saturday July 16. And we hit the upper 90s on two occasions in September, after the start of school.

  8. Storm threat is done for tonight. I’m going to update the blog, basically an edit to remove the storm threat part of the discussion and forecast.
