Hazy, hot, and humid weather has settled into Central New York this week. The heat and humidity comes from a southwest wind being driven by high pressure off the Atlantic Coast. This is known as a Bermuda High, and is a common summertime pattern.
By definition, a heat wave is three days in a row at or above 90 degrees. We expect air temperatures to come up short form an official heat wave. However, the exceptional humidity this time around will make it feel like 90s for the next 3 days. So, while technically not a heat wave, it will feel like it.
Be careful walking your pets this week. You'll want to avoid the heat of the day, the late mornings through late afternoons. When air temperatures climb to near 90, the temperature of pavement can vary between 120-135 degrees. Pets paws can burn in 5 minutes in these conditions. A simple test is to feel the temperature of the pavement. If it's too hot to keep your hand on the pavement, it's too hot for your pets to be on the pavement, too.
The heat is expected to continue into Wednesday, Thursday, and Friday. The hottest day looks to be on Thursday, with the heat index approaching 100 degrees. Take breaks if planning on being outdoors. Avoid strenuous exercise, and be sure to check on your elderly neighbors.
A cold front arrives on Friday and brings a drop in the temperature and humidity. Strong storms are possible on Friday afternoon as the front moves through, with the possibility of heavy rain and gusty winds.
