Temperatures over 30 degrees could feel like 40 with the humidex.
The rising heat could also lead to widespread thunderstorms across the province late Monday afternoon.
The storms will work their way down Lake Superior and then spread across northeastern Ontario. There's a risk in parts of southern Ontario through the overnight as well.
Some of these storms have the potential to be severe in nature with wind gusts up to 90 km/h as well as large hail. According to Environment Canada, an isolated tornado in the Nickel Belt region isn't out of the question either. Residents are urged to stay up-to-date with the warnings in their area and to take the necessary precautions if severe weather moves through.
Heavy rain is expected across much of northern Ontario, which is a relief to firefighters who've had their hands full withwidespread wildfires.

May 25, 2012 1630 UTC Day 1 Convective Outlook
...NORTHEAST... A VIGOROUS SHORT WAVE TROUGH ACROSS SRN ONTARIO IS FORECAST TO CONTINUE TO LIFT RAPIDLY NEWD ACROSS JAMES BAY AND OVER QUEBEC THROUGH THE DAY. COLD FRONT ASSOCIATED WITH THIS DISTURBANCE IS CLEARLY EVIDENT IN SURFACE AND SATL DATA AND WILL CONTINUE TO SPREAD EAST ACROSS LAKES ERIE AND ONTARIO...AND TO NRN NY LATER THIS AFTERNOON/EARLY EVENING. THE FRONT WILL THEN SETTLE ACROSS NRN NEW ENGLAND THROUGH TONIGHT. STRONGEST FORCING FOR ASCENT ALONG THE COLD FRONT WILL EXIST NORTH OF THE BORDER IN QUEBEC WHERE SEVERE STORMS APPEAR MORE LIKELY. WHILE LOW LEVEL CONVERGENCE AND LIFT ALONG THE FRONT WITH SWD/SWWD EXTENT WILL BE WEAKER...LATEST GUIDANCE DEPICTS AREAS OF WEAK TO MODEST DESTABILIZATION FROM NY ACROSS NRN VT BY LATER TODAY. MLCAPE VALUES IN THESE AREAS SHOULD REACH THE 500-1000 J PER KG RANGE WHERE FORECAST SOUNDINGS FROM NAM AND WRF-ARW MODELS DEPICT PRONOUNCED LOW LEVEL VERTICAL SHEAR. ANY STORMS THAT CAN DEVELOP WILL EXIST IN AN ENVIRONMENT WITH SUFFICIENT VERTICAL SHEAR FOR UPDRAFT PERSISTENCE AND ROTATION. GREATEST UNCERTAINTY EXISTS WITH REGARD TO STORM COVERAGE GIVEN THE RAPID TRANSLATION OF THE UPPER TROUGH AWAY FROM THE AXIS OF STRONGER POTENTIAL INSTABILITY LATER TODAY. LATEST INDICATIONS CONTINUE TO SUPPORT THE DEVELOPMENT OF AT MOST SCATTERED TSTMS ALONG THE FRONT DURING A RELATIVELY NARROW WINDOW IN SPACE/TIME FROM LATE AFTERNOON INTO THE EVENING. GIVEN INSTABILITY AND SHEAR FORECAST OVER UPSTATE NY INTO NRN VT...A FEW ROTATING STORMS MAY EVOLVE IN THIS PERIOD AND POSE SOME THREAT OF DAMAGING WINDS OR PERHAPS A TORNADO. SPC HAIL MODEL GUIDANCE INDICATES ONLY ISOLATED HAIL PERHAPS TO AROUND 1 INCH IN DIAMETER.
