Area Forecast Discussion
National Weather Service Jacksonville FL
407 PM EDT Sun Jun 2 2019
...NEAR RECORD TEMPS WITH LIMITED RAIN CHANCES THROUGH MONDAY...
...RAIN CHANCES INCREASE BEGINNING TUESDAY...
.NEAR TERM (through Monday night)...
Pattern of predominately hot and dry conditions to continue
due to a dry Nw flow aloft across the area. Some pooling of
low level moisture from a stalled frontal boundary just south
of the I-10 corridor along with seabreezes and outflows will
lead to isolated to scattered mainly afternoon and early evening
storms mainly across Ne Fl. Activity will diminish during the
evening due to loss of heating. The streak of upper 90s across
inland areas to continue again on Monday while coastal areas
will be in the lower/mid 90s before the seabreeze develops
and eventually moves inland to just east of U.S. Hwy 301.
Lows will be from near 70 inland to mid 70s coast.
.SHORT TERM (Tuesday-Wednesday night)...
Nw flow aloft continues across the area as an upper ridge
builds across the central gulf. The low level ridge axis moves
to the Ne of the area which sets up a return flow of moisture
as a backdoor front sweeps through the area. Pw's increase to
1.80 to 2.00 inches across much of the area by late Tuesday onward.
This results in greater coverage of showers/storms which will initially
be mainly across inland areas late Tuesday afternoon as the east
coast seabreeze drives most storms to the west. On Wednesday...
the low level flow lightens some and veers to the south and southeast
allowing for greater pcp coverage as storms will tend to develop closer
to the coast before spreading inland. There will also be a somewhat
downward trend in afternoon temps especially coastal areas where high
temps will be held to less than 90 degrees while areas well inland will
be in the mid/upper 90s on Tuesday and lower/mid 90s Wednesday.
.LONG TERM (Thursday-Sunday)...
A trend more towards climo early June conditions as atmospheric
moisture levels climb to more seasonable levels with PWATs closer
to the 1.75-2.00" range and weak southwest steering flow which
will support diurnal sea breeze activity during the afternoon and
early evening hours, as rainfall chances become more scattered
each day in the 40-60% range and Max Temps remain above normal but
fall below record levels into the lower to middle 90s inland and
upper 80s/near 90 along the coast each afternoon.
&&
.AVIATION...VFR conditions will prevail. VCTS at SGJ as isolated
to scattered showers and thunderstorms will affect the St.
Augustine area till around 00Z. West winds near 10 knots will keep
the east coast seabreeze near the coast this afternoon...with
winds shifting to the se at SSI and SGJ between 18z-20z.
&&
.MARINE...With lingering trof near or just west of the waters expect a
mainly offshore flow at 10-15 knots with seas 2-4 ft through Monday
and local sea breezes along the coast. High pressure builds north
of the waters Monday Night which brings in a surge of easterly
winds but remaining below headlines. Winds veer and decrease some
towards the end of the week as high pressure builds further
offshore.
Rip Currents: A low risk is anticipated for Monday. The risk
is expected to be elevated Tuesday due to a surge of onshore
winds.
&&
.FIRE WEATHER...
Elevated Fire Danger conditions will continue through Monday
across Southeast Georgia and possibly as far south across
the FL/GA border to the I-10 corridor as a hot and dry airmass
settles in place as frontal boundary remains stationary just
south of the I-10 corridor. Afternoon humidities across Se Ga
falling to around 25 percent this afternoon and 30 percent Monday
afternoon along with wind gusts of 15 to 20 mph will lead to
elevated fire danger conditions. Dispersions will be high
along and north of the I-10 corridor. Both moisture levels
and rain chances increase Tuesday as a backdoor front sweeps
through the area.
