Heat Advisory

A Heat Advisory has been issued for the I-95 corridor from Philadelphia to Baltimore to D.C. on Friday. Temperatures could approach record levels during the afternoon with most spots in the area expected to reach the mid 90s. The June 8th record high for Baltimore is 97F set in 1999. The heat advisory, however, is based on the heat index, which takes into account the high temperatures plus the moisture in the air. When heat and humidity reach high levels, our body’s natural cooling system begins to falter because it is harder for sweat to evaporate from the skin. Early in the hot weather season (May 1st through June 3oth), a heat advisory is posted when the heat index is expected to reach 98F to 105F. Beginning in July, when most of us have become more acclimated to the hot weather, the heat advisory is triggered for heat indices of 100-105. An Excessive Heat Warning is issued for heat indices of 106F or higher, at any time of the year. Luckily, this mini heat wave shouldn’t last long. A cold front is expected to move through the area Friday night with cooler, less humid air arriving in time for the weekend. Until then, slow down, keep hydrated and check on elderly friends and neighbors who might need a cool spot to spend the afternoon. Also, don’t forget to have a shady spot and some water available for pets. My Field Spaniel, Pete, will probably spend the whole afternoon stretched out on the tile floor in the bathroom!
