Enjoy the cool and comfortable weather today because things will be changing drastically as we head into the middle of the week. High pressure centered over the Great Lakes today will be moving over the Mid-Atlantic coastline as we get into Tuesday and Wednesday and this will be one reason the heat and humidity returns to the Twin Tiers. An upper level ridge is beginning to build as well and will gain its full strength by the middle of the week which is the second reason the heat will be on and temperatures climb into the 90s. With this dangerous combination of heat and humidity, we are expecting heat index values to be in the upper 90s and near 100 for some Tuesday and Wednesday. Make sure you check on your elderly neighbors, drink plenty of water and limit your time outside if need be.
