Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Aviation
Scattered showers and thunderstorms will continue to develop
and move propagate south and east causing MVFR local ifr
conditions at the TAF sites today. This convection will
first affect the tampa bay TAF sites from around mid-morning
into early afternoon, then the rest of the TAF sites this
afternoon and early evening. MainlyVFR conditions are
expected outside of the convection into early tonight. Late
tonight after 09z some more MVFR ceilings will be possible
at tpa, pie, and srq as the southwest to west flow brings
moisture in from the gulf.

short term (today - Thursday)...

mid-level ridging over the northeastern gulf of mexico today
will shift east across florida tonight and Thursday as a
strong shortwave ejects from the central plains into the
midwest. At the surface, the subtropical ridge of high
pressure centered over the atlantic is weakly extending into
the florida peninsula this morning, keeping the low level
flow light and variable. Through the rest of today and
tonight, this ridge will slip south as a weak boundary
pushes into florida from the north, setting up a light but
more organized westerly flow pattern across the area.

Atmospheric moisture will increase across the northern half
of the florida peninsula ahead of this boundary, increasing
the chances for isolated to scattered showers and
thunderstorms to develop across the nature coast this
morning. Farther south, surface heating will allow for
scattered thunderstorms to develop early this afternoon,
but these storms will quickly move inland late in the day
as the flow turns to westerly.

On Thursday, deeper moisture (precipitable water values of
around 2.0 inches or more) will lead to a bit more numerous
thunderstorms, but a stronger westerly flow should clear out
coastal locations by the mid afternoon. Otherwise, a similar
pattern will repeat, with temperatures running slightly
above normal.

Mid long term (Thursday night - Tuesday)...

a broad u l trough will extend across much of the CONUS to
begin the period with an u l ridge over the florida
peninsula. A strong u l disturbance will push across the
midwest and ohio river valley Friday and Friday night... Then
rotate and weaken as it lifts across the eastern great
lakes on Saturday. This will briefly allow the u l trough to
sink over north florida... However the u l ridge will build
back across the state during the weekend as the u l
disturbance exits the CONUS and the trough lifts back north
of the state. The u l ridge will hold over the region into
early next week with heights building a bit in response to a
trough digging over the central plains.

At the surface, strong high pressure over the central
atlantic will extend across the florida peninsula Friday
and Saturday with the ridge axis across the florida straits.

This will create onshore boundary layer flow across west
central and southwest florida... Which will promote scattered
showers thunderstorms developing over the coastal counties
during the late morning and early afternoon, pushing inland
across the interior by mid afternoon with an increase in
areal coverage. The ridge axis will gradually lift
north... Extending across the central florida peninsula on
Sunday. This will allow easterly boundary layer flow to
develop over southwest florida which will increase
convergence along the west coast sea breeze boundary... With
higher pops and an increase in areal coverage of afternoon
showers thunderstorms south of the ridge axis. Onshore flow
north of the ridge axis across the nature coast should still
promote best chance of showers thunderstorms during the
late morning early afternoon with activity gradually pushing
inland through the day.

Early next week, the area of high pressure over the central
atlantic will shift a bit east of the area with weak
boundary layer flow developing across the florida peninsula
in its wake. This will likely allow scattered
showers thunderstorms to develop along the west coast sea
breeze boundary over the coastal counties during the early
afternoon... With the boundary gradually pushing inland
through the day eventually colliding with the east coast sea
breeze boundary over the interior which will enhance
shower thunderstorm activity during the late afternoon to
early evening hours. Due to the weak boundary layer flow,
could see outflow boundaries push back to the coast with a
continued chance of showers thunderstorms through the
evening hours each day across all of west central and
southwest florida.

Marine...

the ridge of high pressure across the area will sink south
today and hold across the florida straits for the next few
days, setting up light westerly winds into the weekend.

Daily thunderstorms will cause locally hazardous boating
conditions each day. Otherwise, tranquil marine conditions
will continue.

Fire weather...

relative humidity will remain well above critical levels
through the forecast period.
