JACKSONVILLE, Fla.<\/strong> \u2013 If you\u2019re a fan of classic hits, you\u2019ll appreciate that \u201cmore, more, more\u201d isn\u2019t just a song lyric\u2014it\u2019s our weather theme this week in Jacksonville.<\/p>\n

We\u2019re starting the week off with some of the highest heat and humidity of the season. Even in the early morning, temperatures are climbing fast, with Jacksonville and Mayport already close to 80 degrees. <\/p>\n

By this afternoon, we\u2019re forecast to be about 5 degrees above our seasonal average of 90, pushing up to 95 degrees on Monday and 93 on Tuesday.<\/p>\n

What you\u2019ll actually feel is even higher. We\u2019re looking at heat index values between 100 and 107 degrees, especially during the peak times from 12 p.m. to 6 p.m. <\/p>\n

If you have to be outdoors, remember how quickly that blacktop heats up\u2014keep an eye on your pets\u2019 paws and take care of yourself.<\/p>\n

This heat and humidity pattern is expected to continue for much of the week. The stickiness isn\u2019t going anywhere soon, so keep the Exact Track 4D radar handy and check News4JAX for real-time updates and alerts.<\/p>\n

Scattered rain and storms increase<\/b><\/p>\n

With all this heat fueling our atmosphere, it\u2019s no surprise that showers and general thunderstorms are expected to pop up earlier in the afternoon and grow heavier into the evening.<\/p>\n

While there are some showers already west of Jacksonville today, they\u2019re likely to be very scattered, giving way to our classic summer pattern.<\/p>\n

Here\u2019s one bright side: We are still in a drought, so every bit of rain helps. Over the next seven days, we\u2019re forecasting about 2 to 3 inches of rain, which will be a big benefit for lawns and gardens. <\/p>\n

If you\u2019re a gardener, Mother Nature is expected to do some of the hard work for you.<\/p>\n

Rain chances start around 60% at the beginning of the week, dipping to 40% or 50% midweek and holding steady through Friday. Most of these showers should dissipate before causing any severe issues, though gusty winds and bursts of heavy rainfall are possible.<\/p>\n

Tropical outlook: Keeping an eye on the Gulf<\/b><\/p>\n

We\u2019re also watching the tropics. Right now, there\u2019s an area of low pressure in the Gulf with a low potential to develop over the next seven days. <\/p>\n

In the next 48 hours, chances are near zero, but by the end of the week, there\u2019s about a 30% possibility it could organize.<\/p>\n

Whether it develops or not, this system is likely to bring extra rain to Texas and Louisiana\u2014at this point, it doesn\u2019t look like a threat to us in Jacksonville.<\/p>\n

Rest assured, we\u2019re staying on top of it and will bring you updates on News4JAX as needed.<\/p>\n
