The Heat and Humidity Returns, Just in Time for the First Day of Summer 6/19

Heat and Humidity Returns, Just in Time for the First Day of Summer

It may have seemed that Mother Nature's calendar has been a little off the last several months, with a nice mild winter, unusually early spring temperatures in March, and a return to the 60s for the beginning of June.

It looks like she's back on track though this week. Just in time for the First Day of Summer. Summer officially starts at 7:09pm Wednesday evening meaning we will have 14 hours and 51 minutes of daylight.

So how did we go from several days of beautiful, comfortable, mild conditions to extreme heat?

Well part of it all stems from the same ridge of high pressure. This was our pattern last week and over the weekend.

We saw the High to our north with helped bring in an onshore flow. Basically air travels clockwise around high pressure and brought in the cooler northeast air. Making conditions for the end of last week and over the weekend very comfortable.

Unfortunately that high has shifted to the east over the Atlantic now. Continuing our clockwise flow around the high, now we're seeing south, southwesterly winds which is bringing in the heat as well as the humidity.

The bad news? We'll see several days of extreme heat and humidity. It would not surprise me at all if the National Weather Service were to issue Excessive Heat Warnings for our area for Wednesday and Thursday. Meaning that our heat index or our "feels like" temperature could be around 100 degrees. OUCH! In fact Heat Advisories have already been issued East of the Blue Ridge. Here's our Mid-Week Forecast.

Record high temperatures for Wednesday and Thursday are 96 and 97. Each a degree above our forecast, so tying or breaking a record isn't impossible. The good news is we have a cold front that will be moving into the area Thursday night into Friday which will help cool things off a bit for the end of the week.

But get ready, the summer time heat is here, stay hydrated and don't forget your sunscreen!
