Synopsis.. High pressure ridge axis will slowly move south early this week to the florida straits...with winds veering to the southwest. Winds speeds stay at 15 knots or less through Tuesday... But begin to increase to around 20 knots during midweek as a cold front approaches from the northwest. Higher winds and seas can be expected in the vicinity of Thunderstorms ahead of this front.

Update (rest of today through Wednesday night)
14z water vapor and h4 rap analysis shows an amplified
upper level pattern in place over the conus... Anchored by a
large closed upper low spinning over the upper midwest.

Several impulses are rounding is larger circulation. One
weak shortwave passed through our region last night and was
the forcing mechanism for the showers in the pre-dawn hours.

This energy has no passed by... And the shower activity has
dissipated. Another stronger impulse can be seen dropping
southward into the high plains. This shortwave is destined
to have a much greater impact on our weather during the mid-
week period as it amplifies southward and moves across the
northern gulf of mexico. We will talk more about this
further down this discussion.

At the surface... Atlantic high pressure ridges westward
across the florida peninsula... But is starting to shift
southward toward the florida straits. Low level synoptic
winds which have been out of the east/se the past several
days are shifting to the south as this ridge axis
moves... And eventually will veer to the southwest by
Tuesday.

Rest of today... Earlier clouds and showers are dissipating
allowing diurnal heating to get going. By early this
afternoon this heating will lead to sea-breeze formation.

Without the easterly flow to hold the sea-breeze
back... Expect this boundary to move steadily inland with
time... Making it well past the i-75 corridor by late
afternoon. Due to this change from previous days... Higher
rain chances for diurnal storms will be well inland as well.

Close to the coast... Storms are unlikely later today. The
main sea-breeze collision looks to take place across the
central portion of the peninsula
(polk/highlands/desoto/hardee/sumter counties). Storms are
likely to continue in eastern polk/highlands counties a few
hours past sunset before finally quieting down for the
night.

Tuesday is going to be the transition day between sea-breeze
dominated weather today... And widespread synoptic/frontal
rain Wednesday into Thursday. Synoptic winds will be out of
the southwest by Tuesday... Keeping any sea-breeze
unorganized and pushed well inland and out of our area
before much potential for convection occurs. Off to our
northwest... The pre-mentioned trough will be amplifying
across the central part of the country... With upper flow
becoming cyclonic in nature all the way to the southeast
coast. With little in the way of sea-breeze storms... Most of
the area will be dry (in terms of rain) Tuesday... But the
flow off the gulf will keep this quite humid... Under
considerable high level cirrus to dim the Sun (especially
along and north of the i-4 corridor). There is some
potential for some synoptic showers to approach far northern
areas (levy/citrus) counties late in the day... Although
better rain chances will arrive Tuesday night for these
northern zones.

A significant trough amplification for late may takes place
into the northern gulf later Tuesday night through
Wednesday. Increasing large scale ascent ahead of this
trough... Supplemented by diffluent flow aloft is quite
favorable to support widespread heavy rainfall across the
florida peninsula. Associated surface front will be slow to
advance across the region, and this sets up the potential
for several rounds of rainfall to move across the region. In
addition, increasing wind fields/deep layer shear (35-45kts)
ahead of the trough is plenty to support more organized
thunderstorm/updraft potential. The storm prediction center
has outlooked our entire region in a slight risk of severe
weather (including isolated tornadoes) Wednesday/Wednesday
night... And feel this is appropriate given the nwp ensemble
solutions for this event. Although during the day Wednesday
is likely to be wet... With some stronger storms... The most
organized severe weather potential looks to be Wednesday
evening through early Thursday morning.

Aviation (22/14z through 23/12z)
Vfr conditions will prevail this morning. Sea-breeze will
form in the next few hours and quickly move inland past all
terminals this afternoon... Shifting winds to the southwest.

Best potential for storms later this afternoon will be well
inland. Storms may form in the vicinity of klal, but then
likely will move further east by the evening hours. General
vfr conditions continue overnight into Tuesday morning with
a light south to southeast flow.

Marine
High pressure ridge axis will slowly move south early this
week to the florida straits... With winds veering to the
southwest. Wind speeds stay at 15 knots or less through
Tuesday... But begins to increase to around 20 knots during
midweek in advance of a cold front. Higher winds and seas
can be expected in the vicinity of numerous thunderstorms
expected ahead of this front.
