255 am edt Mon apr 24 2017

Short term Today and tonight... Upper low over N al will move
ese across central ga today and into sc tonight. Very dry air
rotating around low has resulted in just isolated showers over ne
fl/se ga early this morning. Cold front now entering western
zones will move east across the area this morning shifting sw
winds to the west and ending the chance of showers by late
morning. Cooler and drier air will advect into the area today with
cooler temperatures... Reaching the 75 to 80 degree range with
lower humidity. Tonight temperatures will drop into the 50s. With
westerly winds today and wnw winds tonight smoke from the
okefenokee swamp wildfire will likely move across parts of
charlton... Nassau and duval counties.

Tue/wed... Stacked low pressure system over the carolinas will
continue to move NE away from the region with high pressure ridge
slowly building northward up the florida peninsula in its wake. The
near breezy westerly flow on Tuesday will keep the atlc coast sea
breeze pinned at the coast and expect mostly sunny skies and highs
generally in the lower/middle 80s all areas. Weaker steering flow on
Wednesday will allow for both gulf/atlc coast sea breezes to move
inland but atmosphere too dry to support and precipitation and max
temps under mostly skies will push well into the upper 80s inland
and lower 80s at the coast.

Long term /thu-sun/
Thu-fri... Both gfs/ecmwf supporting above normal temps with s/sw
steering flow pushing MAX temps into the lower 90s inland and 80s at
the coast, with a weakening shortwave aloft pushing across the SE us
late Thu and into NE fl/se ga Thu night and washing it out on
Friday. Still too far out but there might be enough moisture to
support some isolated showers/storms mainly during the afternoon and
evening hours on both days but overall not a significant pcpn event
expected.

Sat/sun... Summer-like bermuda high pressure ridge builds over the
region at the surface and aloft and expect well above normal temps
to continue with highs into the lower 90s inland and 80s at the
coast but lack of moisture and high pressure aloft will suppress any
diurnal convection and mainly hot/dry conditions will prevail.

Aviation MostlyVFR ceilings this morning with isolated showers
possible as cold front pushes through the area early this morning.

Tempo MVFR CIGS possible around 1500 feet til around 13z near
frontal boundary. SW winds will shift to the W with frontal
passage.

Marine Sw winds will shift to the west this morning as a cold
front moves across the waters. Scec headline possible for tonight
and Tuesday as winds increase due to deepening surface low off the
carolina coast. After a brief lull... South winds will increase to
scec levels Wednesday night through Thursday night as the pressure
gradient tightens between building high to the east and low
pressure to the west.

Rip currents: low risk today and Tuesday as winds become offshore.

Fire weather
Lack of much significant rainfall with this system didn't help the
wildfire situation much and westerly winds at 10-15g20 mph today and
Tuesday will enhance fire danger despite rh's remaining above
critical levels although the winds will produce pockets of elevated
dispersions this afternoon and again Tuesday afternoon.

Also, the smoke from the wildfire will head towards the east behind
the frontal passage today and will likely impact at least the
northern portions of the jax metro area with the smell of smoke
today and possibly some visibility restrictions tonight.
