The Heat Advisory is in effect through noon today.
Between 3 to 4 p.m. the high is expected to hit 96 degrees, said Charles Mott, National Weather Service meteorologist, with the low at 81 degrees Sunday morning.
The temporary reprieve from the weekend's crippling heat will give way to hotter conditions heading into the Fourth of July holiday on Wednesday, according to the weather service. The humidity will be extremely high as well, leading to unsafe conditions thanks to heat index values over the weekend that will feel like 100-105 at times.
That EXCESSIVE HEAT WARNING is now in effect for Jefferson, Lewis, Northern St. Lawrence and Southwestern St. Lawrence counties until Monday at 10 p.m.
An excessive heat warning is issued when the combination of heat and humidity is expected to make it feel like it is 105 degrees or greater. If you must be outside during the late-morning/afternoon, stay out of the sun as much as possible, seek shade and drink plenty of water. For many communities, the heat index is forecast to reach as high as 110 degrees.
Never leave children, pets or disabled adults in a parked vehicle. Highs will be in the upper 80s. As quick as these storms came in, they moved out and the clearing began.
PRECAUTIONARY: An Excessive Heat Warning means that a prolonged period of dangerously hot temperatures will occur.
Heat stroke is a severe medical emergency.
Another round of hot air will move into the central USA on the Fourth of July.
"If you bring enough water and you just try to keep moving and keep the breeze going you can stay cool and have a good time", one man told FOX29.
Symptoms of heat stroke include hot body temperature, hot/red/dry/moist skin, rapid and strong pulse and possible unconsciousness.
Anyone who'll be working or otherwise spending time outside between now and Monday should take extra precautions.
Wear lightweight, light-colored clothing.
