ROCHESTER, N.Y. – The News10NBC First Alert Weather team has issued a multi-day Yellow Alert for Tuesday through Friday of this coming week. The main impacts will be dangerously high heat and humidity, but Tuesday could also bring some gusty thunderstorms that we need to monitor.
For the next 24 hours: Sunday night will feel very comfortable compared to the temperatures and humidity that is due to set in this coming week. We will stay in the 70s for the early evening hours and drop down into the 60s as we head into the latter part of Sunday evening. Overnight temperatures are expected to drop near 57 degrees with mostly clear skies. Winds will stay between 5 and 10 mph out of the southeast through Sunday night. For Monday, the Threat Tracker remains green. Even though temperatures will near 85 degrees, lower humidity will keep the feel-like temperatures in the 80s. No rain is expected for the majority of Monday and winds will stay out of the east at 10 to 15 mph. All in all, Monday will be a quiet and seasonable start to the week. However, that all changes Tuesday.
Tracking our Yellow Alert: Monday night humidity will start to increase ahead of the incoming warm front. This warm front may bring some gusty thunderstorms through Tuesday. Right now, data shows a cluster of storms in the morning, followed by clearing mid-day, with a second line of storms in the evening. This forecast is still a few days out, so details are still quite muddled. We will keep you up to date each day as the finer data starts to come in over the next 24 hours. Then, timing and intensity should become clearer. Tuesday will still be very warm. High temperatures on Tuesday are expected to reach 90 degrees and dew points are expected to climb into the 70s. This heat and humidity is exactly why we are tracking the intensity of Tuesday’s storms.
Wednesday through Friday will then bring even higher temperatures. We are expecting air temperatures in the low to mid 90s and heat indices between 100 and 105 degrees. Though we are not expecting to hit any record high temperatures, Wednesday’s forecasted high of 93 degrees does come close to the record high of 96 degrees set in 1901.
Remember, the heat index is a guide to how your body responds to the combined heat and humidity. Even though your thermometer may read the low-90s, to your body it may feel like the low-100s. When humidity is extremely high, like it will be this coming week, your body cannot efficiently cool off. Please stay hydrated, limit time outdoors, and listen to your body. If you must be outdoors, be mindful of heat exhaustion and take frequent breaks…
