Latest Forecast

A massive Jet Stream ridge, or "heat dome," will build over the Eastern United States over the next several days and be responsible for an extremely dangerous and record-breaking heatwave through the 4th of July weekend. An Extreme Heat Warning is in effect through 8 PM Friday. High temperatures will soar into the mid 90s to perhaps 100 degrees this afternoon with dewpoints in the low-to-mid 70s. The heat will peak on Thursday and Friday with high temperatures between 100-105 degrees and dewpoints in the mid-to-upper 60s. As a result, heat indices will peak between 105-110 degrees each afternoon and dramatically increase the risk of heat-related illnesses. Blistering sunshine will accompany the blazing heat, and there won't be much relief at night with lows in the mid-to-upper 70s. The record high temperatures of 101 degrees and 104 degrees from July 2-3, 1966, at Millersville University may both be tied or broken. Drink plenty of non-alcoholic beverages to stay hydrated, stay out of or limit time in the sun, and take frequent breaks from the heat in an air-conditioned room or building. Eating a diet high in fruits and vegetables can replenish electrolytes and help with hydration, as well. Never leave children or pets unattended in a vehicle! The internal temperature of a car can reach lethal levels in a matter of minutes on a 100-degree day. Periodically check up on relatives, friends, and neighbors, especially the elderly and those with underlying medical conditions.
