URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 150
   NWS Storm Prediction Center Norman OK
   115 PM EDT Sat Jun 2 2018

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Southeast Alabama
     North Florida
     Southern Georgia
     Coastal Waters

   * Effective this Saturday afternoon and evening from 115 PM until
     800 PM EDT.

   * Primary threats include...
     Scattered damaging wind gusts to 70 mph possible
     Isolated large hail events to 1.5 inches in diameter possible

   SUMMARY...Storms will continue to increase and intensify within a
   very moist and unstable air mass across the region. Modestly
   enhanced mid-level winds could support some semi-sustained/organized
   southeastward-spreading multicellular storm clusters with damaging
   wind and some hail potential.

   The severe thunderstorm watch area is approximately along and 80
   statute miles north and south of a line from 30 miles north
   northwest of Panama City FL to 25 miles southeast of Brunswick GA.
   For a complete depiction of the watch see the associated watch
   outline update (WOUS64 KWNS WOU0).

   PRECAUTIONARY/PREPAREDNESS ACTIONS...

   REMEMBER...A Severe Thunderstorm Watch means conditions are
   favorable for severe thunderstorms in and close to the watch area.
   Persons in these areas should be on the lookout for threatening
   weather conditions and listen for later statements and possible
   warnings. Severe thunderstorms can and occasionally do produce
   tornadoes.

Original story posted below...

Most of Florida is experiencing a dry - and hot - Saturday. However, an upper-level disturbance is likely to turn the skies stormy across the northern third of the state. The Storm Prediction Center highlighted sections of north Florida as having a risk of severe thunderstorms earlier in the day.

NEW! Despite the drier pattern, the risk of a few severe thunderstorms is increasing across portions of #NFla and #FLPanhandle today. Highest chances near #PCB and #Tally by mid-afternoon, then in #Jax metro by early evening. #flwx pic.twitter.com/bG67bcBhg3

A few hours later, just after 1 pm EDT, the National Weather Service issued a Severe Thunderstorm Watch for much of the same area, for the possibility of damaging wind gusts and large hail.  The latest Future Radar (seen below) suggests several of the smaller cells developing in the panhandle will congeal into a larger complex of storms, traversing the I-10 corridor and approximately 40 miles either side of it, all the way to the First Coast.  The storms are most likely near Tallahassee between 2 and 5 pm, Lake City and Gainesville 4 to 7 pm, and Jacksonville 5 to 8 pm.
