Area forecast discussion, May 12, 1:14 AM EDT, 2 hours 34 minutes before

Area Forecast Discussion
National Weather Service Jacksonville FL
114 AM EDT Wed May 12 2021

.AVIATION...[Through 06Z Thursday]
Showers and isolated storms are weakening as they move east
towards the east coast. Have VCSH in TAFs until 08z. Mostly VFR
ceilings overnight with some MVFR conditions by early morning
along with light and variable winds. A cold front will push
southward into se Georgia this afternoon bringing showers and
storms to the TAF sites in the late afternoon and early evening.
Westerly winds near 10 knots today will shift to the nw and
increase late afternoon and then ne this evening as the front
pushes south of the area. Showers will end this evening with MVFR
ceilings spreading across the area by 00Z Thursday.

&&

.PREV DISCUSSION [921 PM EDT]...

.NEAR TERM [Through Tonight]...

A quasi-stationary frontal boundary is stalled just north of our
area, with short wave troughs rolling across what is otherwise
mostly zonal flow aloft. Winds are predominantly out of the west
with areas east of the St Johns river experiencing a wind shift to
out of the east this afternoon. This westerly flow has allowed
scattered to numerous showers and thunderstorms to develop across
NE FL with the Gulf Coast seabreeze. These west winds are also
keeping the East Coast seabreeze pinned near the coast line. Later
this evening, we may also see storms moving with or developing
along outflow boundaries from storms in S-central GA closer to the
frontal boundary. Strong storms are possible this afternoon and
evening, with the primary threats being strong winds and small
hail. High temperatures for today will be in the upper 80s and
lower 90s for inland areas and in the mid to lower 80s along the
coastline. Lows tonight will be in the mid-upper 60s, around 70
along the coastline.

.SHORT TERM [Wednesday Through Thursday Night]...

The front to our north will sink south to near the FL-GA line on
Wednesday evening, and south of our area overnight Wednesday
night. For most of the day, we'll be ahead of the front, staying
warm with temperatures in the 80s and low 90s and with afternoon
ML CAPE values peaking around 500-1000 J/kg, and bulk shear
peaking out around 35 knots. We'll unstable enough to produce a
few strong to severe thunderstorms, the main threats being
damaging wind gusts and small hail.

A much cooler airmass will move into the region behind Wednesday
night's front, but an upper level trough will dig into the
southeast, helping develop an inverted coastal trough off to our
east. Strong northeasterly flow through Thursday night with this
coastal trough setup will keep rounds of scattered showers in the
forecast through Thursday night. Temperatures will be
significantly cooler, with highs in the low-mid 60s in SE GA and
highs in the 70s across NE FL. Overnight lows will range from the
low-mid 50s in SE GA to upper 50s-low 60s in NE FL Thursday night.

.LONG TERM [Friday Through Tuesday]...

The upper level trough will push off the mid-Atlantic coastline
Friday, shifting that inverted trough away from our coastline.
As a result, northeasterly winds will gradually lower in speed as
we move into the weekend. Low level ridging will build in over the
eastern CONUS over the weekend, bringing us a nice weekend. The
ridge will roll off the east coast early next week, bringing a
return of southeasterly flow and likely some seabreeze
thunderstorms. Temperatures will progressively warm from the 70s
Friday back to the 80s for the weekend, with upper 80s to low 90s
returning next week. Likewise lows will warm from the 50s Friday
