Temperatures reached into the mid and upper 90s yesterday. Along with the humidity, it felt like it was over 100 degrees for several hours.
Today we will find a little more in the way of cloudiness, but it's still humid and hot. There might be an afternoon shower or thunderstorm as a cold front approaches the area.
This will be day three of a heatwave. On Tuesday, somewhat cooler and drier air will be here, and I think it'll put to the end to the heat wave in most of the area. This doesn't mean it's going to be cool – it just won't be 90 degrees.
It stays warm and humid for the rest of the week. Temperatures will be well into the 80s for Wednesday and Thursday, along with higher humidity.
A more significant cold front will finally come through for Friday and the weekend, ushering in dryer and more comfortable air.
You can thank the jet stream, which has gone way up into Canada, for the current heat and humidity. This is all quite typical for this time of the year as we are now at the absolute peak of the average summer temperatures. We had the same kind of heat this time last year. Very often, this week is one of the warmest and best weeks to take vacation. Keep that in mind when you're planning 2021.
