Severe Thunderstorm Warning 114, NWS Jacksonville, FL

Area Forecast Discussion
National Weather Service Jacksonville FL
844 AM EDT Thu Jun 28 2018

.Near term.../through this evening/...

At the surface, the region will be between high pressure
to the South and a trough to the North Today. This will result in
a general light Westerly flow. Convection will initiate with
diurnal instability late this morning, with the light Westerly
flow allowing the Gulf sea breeze to push well inland in NE FL,
and the East coast sea breeze should be able to push just West of
I95. In addition, an upper trough will pivot Southeast across the
region Today, which will help to further destabilize the airmass.
Scattered to numerous storms will be expected.

Temperatures will rise into the mid 90s this afternoon, with
indices rising to around 105.

&&

.Aviation.../12z TAF period/...

Showers and storms are expected to impact area TAF sites Today.
Restrictions along with gusty winds will be expected with any
storms which develop. The activity will dissipate toward midnight.
Prevailing VFR conditions are anticipated for the Overnight
period.
