A rare four-day heat wave is predicted beginning Monday but rising humidity today and tomorrow will make it feel more like a heat wave six pack, a rare almost weeklong stretch that will bring unbearable heat and humidity to the Greater Rochester area.
"After a comfortable stretch of weather with lower temperatures and lower humidity, it will be a return to reality for the Northeast and mid-Atlantic as we head into the final days of June," AccuWeather Senior Meteorologist Dan Pydynowski said.
As high pressure strengthens off the East coast this weekend, increasingly humid conditions will be pumped into the region. Despite the muggy conditions, much of the region will remain dry, unlike areas farther to the west.
Today's rising humidity will make it feel like 87 and Sunday's will be worse with humidity index of 95, but Monday is when the heat wave begins in earnest.
Monday will see a high of 97 with a heat index of 104, followed by high temps of 96 on Tuesday, 91 on Wednesday and 90 on Thursday. Monday's nighttime low will be an uncomfortable 77, with the following few days slowly working their way down into the mid-60s.
Meantime, any showers or T-storms that might mitigate the misery won't arrive till Thursday.
