CHICOPEE, Mass. (WWLP) – Another hot day brought temperatures well into the 80s across western Massachusetts. This weather is typical of summer, not early May.
Breaking down the first 10 days of May, average high temperatures for the first 10 days of the month are normally 67 degrees. Average temperatures for the first 10 days of this May have been near 80 degrees, 13 degrees warmer than average.
Why is this all happening? It’s the reverse weather pattern from the one we had this winter.
The jet stream, an area of strong winds high in the sky that separates warm air to the south and cold air to the north, has pushed north of us, allowing warm air into western Massachusetts.
Cooler air has arrived in the middle and western part of the country, bringing unusual late spring snow.
As we go forward in time, the jet stream will dip south of western Massachusetts by Wednesday, bringing cooler air to the area. This cool down does look temporary.
