While the official start to the summer season (the annual solstice) remains just under two weeks away, Mother Nature must not have gotten the memo; summer-like conditions have made themselves at home in the Tri-State after arriving unceremoniously early. Afternoon highs may have only peaked in the mid to low 80s earlier today, but tropical dew point values near 70° made things feel a whole lot hotter. You'll want to get used to that, because this heat and this humidity isn't going anywhere anytime soon. Higher pressure camped out over the Eastern Seaboard will continue to pump Gulf heat and humidity northward into the Tri-State for much of the foreseeable future.
Outside of a few scattered showers and thunderstorms, the evening and overnight should remain primarily dry for the Tri-State. However, that southerly wind flow and ample amount of moisture at the surface will keep temperatures from falling much lower than the upper 60s overnight - we'll dip to just 69° early Tuesday morning. Make sure you have the umbrella as you head out the door in the morning - scattered showers and thunderstorms are expected to affect the region on and off throughout our Tuesday. In fact, the Storm Prediction Center has placed a good chunk of the Tri-State under a "1" on the Threat Index for tomorrow afternoon and early evening; some of the storms we'll see may produce gusty winds and small hail.
Heat indices will routinely reach into the upper 80s and low 90s each and every afternoon through the end of the work week and into the weekend. This combination of excess humidity and seasonal heat will make it nothing less than uncomfortable across the Tri-State. There are some hints that we may finally catch a break late this weekend or early next week - a cold front will sweep through the region and briefly usher cooler, less humid air back in across the Ohio Valley. In the meantime, we're stuck with the swampy, muggy air.
