Area Forecast Discussion
National Weather Service Tallahassee FL
1145 AM EDT Sun Jun 7 2020
.UPDATE...
Heavy rain continues over portions of Taylor, Madison, and Lowndes
Counties where a Flash Flood Warning remains in effect. Highest
rainfall thus far is 8.17" from a mesonet two miles southeast of
Hanson in Madison County. Also getting some reports of downed
trees in Jefferson County, but we suspect this is attributed more
to saturated soils, since winds are only gusting up to 20 mph.
Expect the rainfall axis to lift northward today in response to a
mid-level dry slot moving into the western FL Panhandle, becoming
situated from roughly Dothan to Tallahassee and points east. The
heaviest rainfall with an additional 1 to 3 inches with locally
higher amounts is expected over the Southeast FL Big Bend into
the I-75 corridor of GA.
With drier air moving in aloft, would not be surprised to see a
couple damaging thunderstorm wind gusts with Downdraft CAPE values
increasing. The tornado threat remains low and should be confined
mainly south of I-10 and closer to the gulf coast, where a surface
trough is enhancing low-level shear. Otherwise, the coastal flood
advisory remains in effect for the next high tide this afternoon.

.PREV DISCUSSION [1030 AM EDT]...
.NEAR TERM [Through Tonight]...
Tropical storm Cristobal will continue to track toward the central
Gulf Coast today with a landfall expected this evening in Louisiana.
Cristobal has been and remains an asymmetrical storm which appears
more subtropical than tropical. Local impacts have not changed much.
A widespread 3-4 inches of rain is expected over the our Florida and
far South Georgia zones and a flash flood watch will be maintained.
Locally higher amounts up to twice these values can be expected in
areas where some outer rain banding sets up. This appears to be
happening across our Big Bend zones. 3-hour flash flood guidance
values are generally 3-4 inches and these could be realized through
12Z. This area will also need to be watched for potential tornadoes
as shear becomes more favorable for rotating supercells. The coastal
flood advisory will also be maintained until after we make it
through this afternoon's high tide cycles. Up to 3 feet of
inundation will be possible. We also continue to expect surf heights
peak around 10 feet this afternoon, just shy of warning criteria.
.SHORT TERM [Monday through Tuesday]...
The remnants of Cristobal will be over northern Louisiana Monday
morning and will lift northward into the northern Midwest by late
Tuesday. As it does, the local area may briefly get dry slotted
Monday through most of Monday night before a surge of tropical
moisture fills back in on Tuesday. Will trim back PoPs at least
through the midsection of our CWA on Monday and lower them a bit
Monday night. Likely to categorical PoPs (60-80%) return on Tuesday.
With the tropical airmass in place, locally heavy downpours will
remain a concern. highs both days will mostly be in the upper 80s
with lows Monday night in the lower to mid 70s.
.LONG TERM [Tuesday Night Through Sunday]...
Deep tropical moisture will remain in place through Wednesday night
before an upper trough and associated cold front approach and begin
to scour out the moisture from west to east Thursday through Friday.
Drier conditions but not dry will return for the weekend.
Temperatures will be near seasonal levels.
.AVIATION...
[Through 12Z Monday]
Widespread IFR will continue across the terminals much of the day with
periods of LIFR possible, especially in +SHRA. Improvement to
MVFR is expected by this afternoon with continued SHRA and
vicinity thunder. Southeast winds around 10 knots with gusts to
around 20 knots at ECP and DHN.
.MARINE...
Tropical Storm Cristobal will continue moving northward and make
landfall well to the west of our local waters today. A Small Craft
Advisory remains in effect through Monday. Winds should drop below
advisory levels by daybreak Monday but elevates seas will take
longer to subside. Waterspouts may also occur within some of the
feeder bands across the local waters today. A return to tranquil
boating conditions is expected by mid-week.
.FIRE WEATHER...
There are no fire weather concerns over the next few days.
.HYDROLOGY...
Overall, forecast rainfall amounts are in the 3-6 inch range
across most of the Florida panhandle and Big Bend, with heavy
totals possibly extending into far southwest and south central
Georgia. The flash flood watch continues in effect for all Florida
zones and the lowest tier counties of our Georgia zones. Locally
higher amounts over 6 inches are possible with training feeder
bands, particularly today.
Mainstem river flooding will depend on whether the heavier totals
end up in Georgia or remain across Florida. The farther north the
heavier rain sets up, then the more likely some larger area rivers
such as the Ochlockonee and Withlacoochee could see sharper rises.
If the heavy amounts stay in Florida, then river flooding will be
less of a concern, except for local rivers like the Sopchoppy and
Steinhatchee which will have to be monitored.
In addition, coastal flooding is a concern with inundation generally
remaining 3 feet or less in the minor category. The greatest
inundation is expected to be along the coast of Apalachee Bay.
.SPOTTER INFORMATION STATEMENT...
Spotter activation is not requested. However, spotters are always
encouraged to safely report significant weather conditions when they
occur (while following all local, state, and CDC guidelines) by
