JACKSONVILLE, Fla. – Temperatures this afternoon will climb into the mid-90s for inland areas, while coastal communities can expect highs near 90 degrees. The heat index will feel seasonably hot but is not expected to reach Heat Advisory levels.
By this evening, the focus shifts to storms. Areas along I-75 from Lake City southward face the potential for localized heavy rain and localized flooding.
This weekend: A tropical airmass moves in
A deep tropical airmass is set to overspread the region through the weekend, bringing numerous showers and thunderstorms each afternoon and evening, regardless of any tropical development offshore.
The east coast sea breeze is forecast to push far enough inland to keep the most intense storms further west, leaving the coastal areas relatively dry.
Flooding the primary concern
The main hazard with this weekend’s storms will be periods of heavy rainfall capable of producing localized flooding. Repeated rounds of storms in those areas make flooding the primary threat.
Frequent lightning and locally gusty winds will also accompany the stronger storms throughout the weekend.
Saturday: Still hot with dangerous heat index values
Despite all the storm activity, temperatures Saturday will remain seasonably hot, with highs expected in the lower to middle 90s. Peak heat index values are forecast to range between 102 and 107 degrees, so be sure to stay hydrated and always have an indoor space nearby to seek relief from the heat.
Sunday: Slight cool-down, but still humid
Increasing cloud cover and widespread showers and storms on Sunday should knock high temperatures down a bit, with most areas will see upper 80s to lower 90s.
