What's New / NOTES
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

307 pm edt Mon jul 24 2017

Near term through Tuesday
Isolated to widely scattered storms across northeast florida will
continue to quickly push towards the atlantic coast and move
offshore by late afternoon. Mid level ridge over the florida
peninsula has kept convection across northeast florida on the very
tame side today.

Activity developing across the florida panhandle and up through
southeast georgia will continue to increase in coverage and
intensity with storms expected to become numerous across southeast
georgia later this afternoon as troughing approaches the region.

Storms will move northeastward at a decent clip so the threat of
heavy rainfall will be inhibited somewhat, but still cannot rule
out some locally heavy rain across southeast georgia if storms
train over the same areas and possibly along the immediate coast
where the there is some evidence of a very slow moving seabreeze.

Activity will wind down quickly across northeast florida but will
linger across southeast georgia into this evening. All activity
across southeast georgia should push offshore by late evening.

Moist southwest flow will continue to bring the threat of some
late night showers off the gulf. It will be another muggy night
with min temps a few degrees above normal.

Activity will get off to an early start on Tuesday morning with
numerous storms expected across southeast georgia as the trough
pushes even closer to the area. Deep moisture will bring a locally
heavy rainfall threat into play across southeast georgia on
Tuesday as well as some localized strong wind gusts due to precip
loading. Northeast florida will continue to feel the influences of
the upper ridge, thus convective activity will be more isolated
to widely scattered, with the lowest chances across our southern
zones. A few strong to possibly severe storms however will be
possible in northeast florida near the florida georgia border late
in the day.

Short term Wed through fri...

a mean layer trough will persist across the region during this
period with a 500 mb trough extending across the eastern CONUS and
across the eastern gulf coast region while a surface trough axis
meanders across georgia while becoming diffuse. Surface high
pressure centered over the western atlantic will extend a ridge
axis across south florida toward another ridge center holding over
the central gomex. This pattern will bring prevailing wsw
steering flow across SE ga and NE fl and a more dominant west
coast sea breeze convective regime. Expect an early start to
rainfall each morning across SE ga due to proximity of the surface
front and across the suwannee river valley due to prevailing wsw
flow. Then rainfall will pressing inland toward the atlantic coast
through the afternoon hours, expanding in coverage and increasing
in intensity as diurnal instability increases. The main driver of
daily convective coverage will be atmospheric moisture content as
forcing and instability will be in place with the mean layer
trough across the region.

Wed & thu... Precipitable water values (pwats) will be at or above
2 inches across SE ga and the suwannee river valley and combined
with forcing from the surface front and potentially a broad
surface low, locally heavy rainfall is expected. Drier air will
bring more limited precipitation coverage across portions of ne
florida roughly from gnv to sgj Wed afternoon with a typical west
coast sea breeze regime, but by Thu moisture rises to near 2
inches pwat values as the trough deepens farther south and thus
rain chances will increase across much of NE fl. Given the
dynamics across the region and high moisture content, rainfall
potential will exist overnight as well.

Fri... The 500 mb trough and associated PVA presses downstream of
the forecast area, which a decrease in precipitation potential
compared to the past 2 days. Although upper level forcing will be
weaker, elevated moisture content with pwats 1.75-2 inches will
fuel diurnally enhanced showers and tstorms.

A few strong to severe storms will be possible each day, mainly
during the afternoon hours with the greatest threats locally heavy
rainfall and gusty wet downburst winds.

Temperatures will trend near normal with maximums near 90 and
minimums ranging in the 70s. Near 90 temperatures will even reach
the beaches each afternoon due to delayed east coast sea breeze
under prevailing wsw flow, while mid to upper 80s for daily maxes
will be possible farther west across portions of SE ga and the
suwannee river valley due to cloud cover.

Long term Sat through mon...

yet another mean layer trough axis will deepen across the region
fri with another 500 mb short wave trough carving southward across
the eastern gulf coast region and a surface front moving across
north ga. Locally, SW flow will continue to bring a more dominant
west coast sea breeze sat, and with increased moisture and forcing
with the next trough, rain chances increase this weekend, with
widespread rainfall Sun & Mon with pwats once again above 2
inches. Mon the upper trough axis begins to retrograde across the
gulf coast region as the mean layer 1000-500 mb ridge axis lifts
northward across the florida straits. This westward shift will
gradually bring lowering rain chances from east to west mid-week
next week as subsidence and drier air advances over the forecast
area from the south.

Temperatures will trend near normal with maximums near 90 to
lower 90s and minimums ranging in the 70s.

Aviation
The threat of thunderstorms is winding down across northeast
florida with only a low chance of storm impacts, mainly along the
coast. The thunderstorm threat in southeast georgia, however, is
just ramping up and will continue to do so through the afternoon
hours and into the early evening. Ssi could possibly see a couple
of rounds of storms, and we will do our best to try and time this
activity as we go through the afternoon. Ifr conditions in heavy
rain and gusty winds will be possible at ssi through early this
evening. Otherwise,VFR conditions will prevail.

Marine
High pressure will be southeast of area waters this week. A trough
of low pressure is expected to move southeast over the region
toward mid week and dissipate. Another trough is expected to move
southeast toward the region this weekend.

Rip currents: low risk.
