Friday July 22 – It’s mid summer and we have a heat wave building. That should be expected and not a headline. But the famed Heat Dome across the nation is building east and we will be on the edge of the region that could reach 100°F. I say could because there are some signs in the upper air pattern that might hold many in the upper 90s. Regardless, the humidity will make it feel like well over the century mark. So it will be dangerous to be outside at times.
This morning, there is a line of storms in northern Pennsylvania dropping south. The latest radar simulation suggests this will hold together and reach central Maryland later today. Ahead of it, clouds will filter the sun and perhaps hold back the temps. The problem here is that this is a relatively new development that the mid range models didn’t catch on. Check out the simulation, then compare to the Storm Predication Center outlook for severe storms. See more notes on the heat below.

Severe Storm Outlook
Heat Wave:
I am purposely NOT showing the temperature outlook over the next week because I don’t want to get hung up on 99°F vs 101°F. Here is a look at the temps and Heat Index today… The upper air pattern such as what will carry the storms out of PA today, could hold the core of the heat dome just out of our range. If we reach 100°F, it would be the first time since July 2012. But it will surely feel like it, so plan your weekend accordingly.
