Area Forecast Discussion
National Weather Service Jacksonville FL
223 PM EDT Sun Sep 24 2017
.NEAR TERM /Through Monday/...
Overview: The near term begins with an upper trough across the
intermountain west, a ridge over the mid Atlantic and northeastern
conus, the remnants of Jose east of the northeastern conus, an
upper low along the northern Gulf coast, and Hurricane Maria
northeast of the Bahamas well to the east of the region. The upper
trough will lift northeast on Monday, with a shortwave
reinforcing the trough over the intermountain west. The upper
ridge over the northeastern conus will remain stationary, and the
upper low over the northern Gulf coast will begin to shear out on
Monday. The remnants of Lee will continue to weaken and push off
to the northwest. Hurricane Maria will move north to southeast of
the Carolinas on Monday.
Rest of today and tonight: An isolated shower moved into the
coast of northeast Florida late this morning. Otherwise mainly dry
conditions have prevailed. Breezy east northeasterly flow will
continue through the afternoon along the coast, and a few
showers/storms are possible across northeast Florida through the
afternoon. An isolated coastal shower is possible for St Johns and
Flagler County overnight. Otherwise, dry conditions will prevail.
Overnight lows will be in the upper 60s to near 70 inland and the
low to mid 70s along the coast.
Monday: Even drier continental air will rotate into the region
from the north as Hurricane Maria moves north of our latitude. A
dry and pleasant day is forecast for the region, with light
northerly flow. An east coast sea breeze will develop in the
mid/late afternoon with northeasterly winds. Highs will be in the
upper 80s to around 90 degrees, except the mid 80s for the coast.
.SHORT TERM.../MONDAY NIGHT THROUGH THURSDAY/...
Hurricane Maria is expected to slowly move Northeast of the region
this period, while high pressure builds to the Northwest. The
resultant flow will be Northwest/West which should be a dry flow.
Will maintain a dry forecast for this period, with sunshine yielding
above normal high temperatures.
.LONG TERM.../THURSDAY NIGHT THROUGH SUNDAY/...
The combination of a trough extending Southwest from Maria and an
upper trough pivoting through from the West Thursday night into
Friday, could develop a surface low over or near the forecast area
Friday afternoon into Saturday. With the potential for this low and
trough across the region this period, will maintain lower end pops.
Temperatures late in this period will depend on how fast the low and
trough pass through. At this point, have the trough to the Southeast
for Sunday, with cooler air advecting in from the Northwest, so
expecting below normal readings Sunday.
&&
.AVIATION...
Stratocu has moved in from the Atlantic, causing some brief high
MVFR cigs along the coast. Scattered cumulus 2.5-5kft will prevail
through the rest of the afternoon. East northeast winds 10-15
knots will continue through the afternoon, with light and variable
winds overnight.
&&
.MARINE...
Hurricane Maria will move slowly northward early this week, which
will bring increasing swells to the regional waters. East
northeast winds will also be 15 to 20 knots. Seas in the near
shore waters will build to 6-9 feet from tonight through Monday
night. 6 to 9 foot waves offshore will peak in the 9-12 foot range
late tonight through Monday. SCA level seas are likely to persist
for much of next week in the offshore waters due to large swells
from Maria, which is expected to turn northeastward by late next
week. Maria will pass our latitude on Monday well to our east,
allowing winds to shift to a northerly and then northwesterly
direction with decreasing speeds by late Monday and Tuesday.
Rip Currents: High risk of rip currents through Monday due to
increasing swells from Hurricane Maria. High Surf Advisory in
effect through Monday for surf 7 feet or higher along the coast of
northeast Florida. Beach erosion will become an increasing
concern during times of high tide through early this week.
&&
.HYDROLOGY...
A Coastal Flood Advisory remains in place for the St. Johns River
basin, as minor flooding continues during each high tide cycle
from Jacksonville southward to Palatka. Further south, flooding
approaches moderate levels into the Welaka and Ocklawaha River
basins. Strengthening onshore winds may keep the risk of minor to
moderate flooding in place during times of high tide through early
this week.
Moderate flooding continues along portions of the Santa Fe and St.
Mary's Rivers, with minor flooding along the Satilla River east of
Waycross and portions of the Upper Suwannee River north of I-10.
