Strong thunderstorms that developed across Southwest Florida Sunday evening are winding down, with quieter conditions expected overnight. Once the storms fade, skies will clear, and temperatures will settle into the mid to upper 70s by Monday morning.
Temperatures have climbed into the mid-90s across Southwest Florida, with heat index values once again reaching the triple digits, well above average for late June. If you're spending time outdoors, be sure to stay hydrated and take frequent breaks in the shade.
Monday is shaping up to be one of the hottest days we've seen so far this summer. A touch of Saharan dust in the atmosphere and a slightly drier air mass will help limit storm development, allowing temperatures to soar into the mid and upper 90s across much of Southwest Florida.
Forecast highs include 96 degrees in Fort Myers, 95 in Punta Gorda, and 93 in Naples. Those temperatures will put Fort Myers and Naples within a degree or two of daily record highs, while Punta Gorda could approach its record as well.
While actual temperatures will be hot, it will feel even hotter. Heat index values are expected to climb between 103 and 107 degrees during the afternoon, especially away from the immediate coast. Inland Collier County could see "feels-like" temperatures approach 109 degrees. If you're spending time outdoors, be sure to stay hydrated, take breaks in the shade, and limit strenuous activity during the hottest part of the day.
Looking ahead, the heat will continue through much of the week with highs generally in the mid-90s. Daily storm chances will gradually increase beginning Tuesday, with scattered afternoon and evening thunderstorms expected through the Independence Day weekend.
Temperatures should ease back slightly toward the lower to middle 90s by late week as cloud cover and rain coverage increase.
The National Hurricane Center continues to monitor an area offshore of the southeastern United States for possible development later this week. A broad area of low pressure is expected to form near a stalled front off the Carolina coast Monday or Tuesday.
Gradual development is possible for a couple of days as the system drifts westward, but environmental conditions are expected to become less favorable by the end of the week. The latest outlook gives the system a near 0% chance of development over the next 48 hours and only a 20% chance over the next seven days.
At this time, the system poses no threat to Southwest Florida and is expected to remain well to our north.
If you're heading out on the water today, keep an eye on the radar for developing storms. Winds will be out of the east at 5 to 10 knots before becoming westerly later in the day, with a light chop in the bays.
Don't forget to reapply sunscreen, today's UV index is an extreme 11!
