Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK

Valid 102000Z - 111200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
A few thunderstorms are expected across parts of central and south
Florida late this afternoon into tonight.
...20Z Outlook Update...
Scattered thunderstorms have initiated near the surface front now
advancing southward across the central peninsula, with additional
storms developing near and just inland of Gulf coastal areas south
of Tampa, perhaps aided by weak cooling around the 700 mb level.
Latest Rapid Refresh suggests that this mid-level cooling will
continue overspreading south central interior portions of the
peninsula (mainly across and north of the Lake Okeechobee vicinity)
through the remainder of the afternoon, before the loss of daytime
heating contributes to diminishing thunderstorm probabilities over
the interior peninsula. Thereafter, as pre-frontal near-surface
winds veer to a north-northeasterly component this evening into the
overnight hours, and the front continues to advance southward,
lingering thunderstorm development is expected to become focused
near or just offshore of southeastern peninsula Atlantic coastal
areas.

.PREV DISCUSSION... /ISSUED 1015 AM CST Mon Jan 10 2022/
...FL...
Visible satellite imagery shows mostly clear skies across central
and south FL today, where strong heating and dewpoints in the
mid-upper 60s will promote moderate afternoon MLCAPE. Mid-level
temperatures are cool (-14C at 500mb), further aiding in the degree
of instability. Scattered afternoon showers and thunderstorms are
expected to develop over the east-central and southeastern
peninsula, perhaps aided by sea-breeze interactions. Vertical shear
is weak, limiting much severe threat. Nevertheless, the strongest
updrafts may produce small hail and/or gusty winds. Considered a
small MRGL east of the lake between MLB and MIA, but the very small
area and weak vertical shear limit confidence in the severe risk.
