Peak Of Summer Brought Us A Brief Break. Now It's Back To Humidity, Downpours, And Eventually Heat Again

On average, if you have to pick the exact height of summer, it's right around July 21.

My Quick Fire Hydrangeas are what I consider at their 
peak and prettiest right now. They follow the season starting
off white in early summer, turning pink at the peak of summer
and gradually going to a russet in the autumn. 

That's right around the time we've had half our heat waves, half our spells of humidity. The hottest days of summer are often right around that date. 

You start to notice the start of a journey toward autumn about now.   

Vermonts trees, forests and hillsides are still the royal green of summer, but a few of the leaves are looking tired or ragged. If you look closely, you see hints of red in the swamp maples.  

As I sat out in my yard last evening, I noticed a relative lack of birds compared to spring and early summer. We're starting to see the sun set a little earlier. 

July 21 this year turned out to be a little cooler than it has been lately, belying the reputation as the peak of summer.  The high temperature in Burlington Sunday was 79 degrees. That ended a streak of 19 consecutive days with high temperatures of 80 degrees or more. The streak was good enough to become the sixth longest set of consecutive 80s on record. The longest such streak was 29 days in 2018.

Chances are, the hottest temperature of this summer came early in the season. The toastiest we've gotten so far, at least as measured in Burlington, was 96 degrees on June 19.

We might be halfway through summer, but there's plenty of it left. Plenty of time for more downpours, sunny days, heat waves, you know the drill.

UP NEXT

As of today, Vermont's summer weather of 2024 is up to its old tricks. Like we've seen so often this summer, it's gotten humid and wet, with locally heavy downpours. That'll be our state of affairs through Thursday.  

As has been so often the case this summer, National
Weather Service radar is lit up with rain, with 
locally  heavy downpours in red. Image is
from around 6:40 a.m. today. 

Rainfall has been highly variable overnight and early this morning, as is typical of summer. The northern Adirondacks of New York have had enough downpours to trigger a local flood warning up there early today. 

Areas of heavy rain also showed up on radar across far northern Vermont, though I haven't seen any indication of a flood risk there. 

Meanwhile, Burlington had just 0.04 inches of rain as of 7 a.m. 

We'll need to watch out - once again - for instances of flash flooding over the next three days, with Thursday the likeliest day to produce trouble. If indeed we get any trouble. 

The risk of flash flooding is the usual harassment we've had all summer: There's a chance of isolated flood problems, but nothing widespread or super scary like on July 10-11. 

The rain we're getting this morning will tend to taper off as we head toward noon. In the afternoon, we'll see some more showers and thunderstorms erupt.  That's when an isolated, slow moving thunderstorm in one or two spots could cause some new local washouts or culvert problems. The chances of this happening today are quite low, but not zero.

The sticky weather that's returned will, um, stick around for a few more days. Nights will be stuffy, but at least days will only reach the low 80s, as clouds and showers will hold temperatures down a little. 

Wednesday will be sultry again with the usual hit and miss storms. Afternoon and evening are the most likely times for that, as usual.

We start to get some weak boundaries and cold fronts approaching and passing through Thursday, which will make even more showers and downpours and storms erupt in the humid air. That's why I'm eyeing Thursday as a potential flash flood day, again in a few isolated places. Most of us will be fine, but we'll need to keep an eye out. 

DRYING OUT?

Beyond that, there's good news and bad news. High pressure that originated in south central Canada will drift in from the west and northwest by Friday.  There's been record heat in central and western Canada, so the air with this one is warm. 

Friday and Saturday might well end up being warmer than earlier in the week. But the humidity will temporarily crash so we'll have a couple of fairly comfortable sleeping nights and some really decent beach days over the weekend.

Bonus: As it looks now, we might have at least four consecutive days of rain-free weather with this. 

This high pressure looks like it will want to strengthen overhead and also team up with the dreaded offshore Bermuda High. Early indications are this will set us up for another hot spell, with more 90 degree days possible starting Sunday or Monday.
