...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF

THE CENTRAL AND SOUTHERN FLORIDA PENINSULA...



...SUMMARY...

Strong thunderstorms, capable of marginally severe wind gusts and

hail, will be possible across the central and southern Florida

Peninsula on Monday.



...Central and Southern Florida Peninsula...

An upper-level trough will move to the Atlantic Seaboard on Monday,

as a cold front advances southward across the central and southern

Florida Peninsula. Along and south of the front, surface dewpoints

should generally be from 65 to 70 F. As the moist airmass heats up,

scattered thunderstorms are forecast to develop around midday. This

activity is expected to persist through much of the afternoon,

gradually progressing southeastward to near Miami. NAM forecast

soundings from 18Z to 21Z to the northwest of Miami have MLCAPE

peaking near 1000 J/kg, 0-6 km shear around 50 knots, and 0-3 km

lapse rates reaching 7 C/km. This environment could support an

isolated supercell, associated with hail and damaging wind gusts.

However, multicell is expected to be the dominant storm mode. The

stronger short line segments could be capable of a marginal

wind-damage threat. The threat is expected to be concentrated during

the mid to late afternoon.
