...HEAT ADVISORY REMAINS IN EFFECT...

* HEAT INDEX VALUES...In the upper 90s due to temperatures around 90, and dewpoints around 70.

* TIMING...Monday afternoon into early evening.

* IMPACTS...The heat and humidity may cause heat stress during outdoor exertion or extended exposure.

The combination of hot temperatures and high humidity will combine to create a situation in which heat illnesses are possible. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun and check up on relatives and neighbors.

  • Take extra precautions, if you work or spend time outside.
  • Reschedule strenuous activities to early morning or evening.

  • Wear lightweight and loose fitting clothing.
  • Drink plenty of water.

Showers and thunderstorms tonight may produce gusty winds and locally heavy rainfall leading to localized poor drainage flooding.

Showers and thunderstorms on Tuesday may produce gusty winds and locally heavy rainfall leading to localized poor drainage flooding.

National Weather Service (NWS) says today will be hot and humid with isolated afternoon thunderstorms. The best chance for thunderstorms will be Monday night and Tuesday as a cold front moves through the region. High pressure will bring cooler and less humid weather for Wednesday through Friday.

...A cold front will approach the region late
tonight and cross the area on Tuesday. Airmass ahead of this boundary will be rather juicy with precipitable water values around 2 inches so any convection will contain heavy downpours and possibly cause some poor drainage flooding, especially in urban areas...The cold front will likely pass through the Finger Lakes region during the mid-morning hours reaching the Utica/Binghamton area around midday...
