Sunday, June 21, 2026, started steamy in Orlando, with clear, muggy skies and temperatures in the mid-70s at Orlando Executive Airport. The mostly sunny morning is expected to trade in the blue sky for scattered showers around midday as sea-breeze boundaries collide, with the afternoon high still headed for about 92°F. If your plans are outside, keep Plan B handy, since storms are possible through the early evening and can pop up in a hurry.
Afternoon Storms Likely
Showers and thunderstorms are expected to fire up inland and push east this afternoon, with a roughly 60% chance of rain and highs near 92°F, according to the National Weather Service. Most storms should be brief, but slower-moving cells could drop a few tenths of an inch of rain, and forecasters say isolated pockets could see 2 to 3 inches in heavier downpours. The most active window is expected from about noon into the late afternoon, with the greatest coverage west of I-95 and along the coast.
Storm Hazards And Commute
Any stronger storm can quickly produce damaging wind gusts and frequent cloud-to-ground lightning, so pull off the road if visibility drops and avoid driving through standing water. Look for ponding on low-lying streets and slick pavement during the heaviest cells, and build in extra time for afternoon commutes and school pick-ups. Boaters and beachgoers should plan to head to shore at the first rumble of thunder, since lightning can strike well away from the core of the rain.
Heat Returns Monday And Tuesday
Rain chances decrease later in the week as drier air moves in, but the tradeoff is a jump in temperatures into the mid to upper 90s on Monday, June 22, and Tuesday, June 23, with heat-index values near 105 in some inland neighborhoods, according to the National Weather Service. Officials say the start of the workweek brings widespread Major HeatRisk impacts, so it is a good idea to shift strenuous outdoor work to the coolest hours of the day and keep water close at hand. As always, never leave children or pets unattended in a parked car, even for a short errand.
Local Cooling Options
Orange County recently lowered its heat-activation threshold to a 103°F heat index and will offer free LYNX bus rides to designated cooling locations when that threshold is reached, according to Orange County. County parks, splashpads, libraries and community centers are available during hot spells; call 2-1-1 or check the county site for a current list of open locations. If someone you know is vulnerable to heat, plan ahead and make use of those resources during the peak afternoon hours.
Bottom Line
Orlando gets a muggy morning, scattered but potentially strong storms this afternoon, and a quick turn toward hotter, drier weather by early next week. Keep an eye on radar for fast-forming thunderstorms, secure loose items on patios and in yards before storms move in, and be ready to tap county cooling resources if the heat index spikes later in the week.
