Area Forecast Discussion
National Weather Service Tampa Bay Ruskin FL
834 AM EDT Sun Apr 30 2017

.UPDATE...
Lots of clouds across the region this morning as an upper-
level short-wave trough moves by. Clouds will gradually thin
from west to east today, with sunshine returning to the
beaches around noon or so, then to the rest of the area this
afternoon.

Moisture has increased since yesterday, so we will likely
see more cumulus development during the afternoon hours.
This combined with slightly cooler low-level temperatures
will keep us a few degrees cooler than yesterday, although
still likely reaching the lower 90s.

We may see a band of sea breeze showers and thunderstorms
develop late this afternoon and early this evening from
about the Tampa Bay area north. These would occur primarily
near or west of I-75 and move northwestward toward the Gulf.

Last nights surge has brought seas up to 4 feet just
offshore. Winds are forecast to remain rather gusty and turn
more southerly and a bit onshore right at the beaches
during the afternoon hours. The combination of gusty winds
and choppy seas will result in conditions favorable for the
generation of strong rip currents. Will be issuing a rip
current statement with the morning update for Pinellas and
Hillsborough counties south through Lee County.

&&

.AVIATION...
VFR expected next 24 hours. Gusty southeasterly winds may
briefly turn southerly as a sea breeze tries to advance
inland between 20Z and 00Z.

&&

.MARINE...
Seas are about a foot higher than forecast in the nearshore
waters, so will update to include these higher seas.
Otherwise expect rather robust southeasterly winds through
the early afternoon hours, then some relaxation of the winds
as a sea breeze develops. Winds will come right back at 15
to 20 knots again tonight. A weak frontal boundary will move
into the region Monday night but only serve to collapse the
pressure gradient and result in lighter winds and seas
through mid-week.
