OTHERWISE: As noted in the title, strong to potentially briefly severe thunderstorms are possible today mainly from Volusia County and South as noted in the graphic.
Winds along the coast are expected to become more southerly to side shore or nearly so, which will aid in low level helicity east of I-95. Additionally, there is a chance of some better low level wind shear (albeit very weak) north of MLB toward DAB along the southern fringes of Beryl's mean circulation pattern as well as a CAPE (convective instability) gradient setting up near the Brevard/Volusia Line or a bit further north right at those cross-hairs.
Thus, where ever that gradient sets up could be where at least one option for a strong/severe storm, perhaps two with one even further north than DAB. The other favored area would be along the Lake Shadow Gradient which should set up near South Brevard to Vero Beach zone. A stronger storm with hail could set up in Western or Central Dade/Broward Area as well.
There is a chance of a brief landspout tornado or waterspout mainly east of I-95 or a waterspout offshore Brevard or Southern Volusia, and a funnel cloud could also be observed from northeastern Osceola County to the coast as far south as Palm Bay. Hail is also possible , potentially near severe category size of 1 inch..but if so, very very isolated as today's unfolding will be in any case.
Activity expected to commence after the morning convective temperature of 83F is broken, thus, could be as soon as 1:30pm - 2:30pm and to continue in various locations and various times noted in the image above through sunset with one or two storms near or approaching the coast after 6pm, most likely south of MLB toward Sebastian and Vero Beach.
TUESDAY/WEDNESDAY: With 'Beryl remains' lifting toward the ENE out and away cloud cover will be appeased, and more statewide chances of storms both days, with strongest activity east 1/2 of state (in general). Locations and degree of strength of storms each day will be as always in question. The
storm could begin to interact with the Atlantic on Wednesday and begin to
emerge offshore the coast of North Carolina, but by that time would be
THURSDAY/FRIDAY: Chances are a weak disturbance will eject northward from Western of Central Cuba as is being noted which will impact coastal areas of far south Florida, but details, if even so, remain too sketchy to elaborate upon this morning given the time between now and then, anything could
change. Out of interests sake, this day could be a big severe weather makes for much of Northern Alabama and Georgia northward to the eastern Great
Lakes region and eastward to Southern Pennsylvania...(Friday time frame)
EVENTUALLY: A frontal boundary and lowering atmospheric moisture by
Sunday or Monday state wide (possibly) with a more westerly flow, the ridge axis at the mid levels being near the Florida straits, could set up for that hot spell mentioned a few posts ago early next week.
