KEY MESSAGES

Updated at 711 AM EDT Sun Jul 12 2026

- Heat indices between 105-110 expected each day into next week. Take appropriate precautions during extended periods outdoors.

- Drier air has moved into the region leading to lower rain chances across the coastal areas. A few showers and storms may develop across interior areas each afternoon into early next week.

SHORT TERM

(Today through Monday) Issued at 134 AM EDT Sun Jul 12 2026

Not much in the way of synoptic influence within the vicinity of South Florida this morning other than deep layer high pressure over the western Atlantic and into the FL peninsula. This will continue to facilitate low level southeasterly flow today and tomorrow. A Dry and hazy Saharan air mass continues to overspread the region through the short term period, leading to reduced chances for showers and storms today and Monday although a few showers and storms should still manage to develop across interior South Florida each afternoon. High temperatures today and tomorrow are expected to be well above average into the mid to upper 90s. Expect mid 90s along the immediate east coast, getting warmer as you head westward with upper 90s across SW Florida. Very similar conditions expected on Monday, except maybe a degree or two warmer in some areas. Maximum heat index values will once again range from 105-110 degrees. A Heat Advisory will be in effect for Miami Dade and Broward County today and likely Monday as well. While the high temperatures are stealing the show, the low temperatures will also be quite above average with most of the east coast metro area struggling to dip below 80...gross! Limit strenuous outdoor activities and take action when you see symptoms of heat exhaustion and heat stroke.

LONG TERM

(Monday night through Saturday) Issued at 134 AM EDT Sun Jul 12 2026

Drier than average conditions persist through most of the upcoming work week as a plume of Saharan dust makes its way across the area.A few showers or storms may manage to develop each afternoon across interior areas, but rain chances will remain in the 20-30% range each afternoon with highest chances across interior and SW Florida. An increase in moisture is expected for next weekend where rain chances will increase to 30-40%. The main story this week will be the heat - with afternoon high temperatures in the mid to upper 90s each day and heat index values ranging between 105-110 degrees. Heat advisories are possible each afternoon, although this will be evaluated on a daily basis.
