Area Forecast Discussion

118 AM EDT Sat Jun 6 2020

[Through 06Z Sunday]

While TAFs are VFR initially, cigs will decrease through the day
today to MVFR with some vsby restrictions also possible. By the
afternoon, rain will spread northward across the sites.
Instability is limited so only a mention of showers in the TAFs
for now, though an isolated thunderstorm cannot be ruled out.



.NEAR TERM [Through tonight]...
Afternoon convection should diminish this evening for much of the
area, as large scale forcing is initially rather weak. After
midnight, showers and thunderstorms associated with the outer
reaches of Cristobal may begin to move into the coastal waters and
approach the coast.

.SHORT TERM [Saturday through Sunday night]...
Tropical Storm Cristobal will move north through the central Gulf
on Saturday. However, the system will be very asymmetric, with a
large area of showers and thunderstorms well to the northeast of
the system. With easterly flow in place at the surface tomorrow,
isentropic lift will increase through the day as the southeasterly
and southerly flow associated with Cristobal approaches the area.
This will lead to an increase in showers and thunderstorms
throughout the day, especially across Florida. Guidance has been
fairly consistent in bringing a large band of heavy rain into the
Big Bend and Panhandle sometime from Saturday evening into early
Sunday. This band will likely bring the heaviest rainfall into the
area, largely focused south of I-10. This will also bring the
strongest winds to the marine areas as well, with possible gusts
to tropical storm force offshore. At this time, the stronger winds
are not expected onshore. However, with the strong flow over the
waters, some storm surge flooding is expected along the Big Bend
coast. While guidance has trended downward from yesterday, there
is still the potential for 2 to 4 feet of inundation, especially
near the top of Apalachee Bay. This is covered by the Storm Surge

Guidance generally weakens this primary band once it moves onshore
during the day on Sunday, with coverage of rain gradually
diminishing. Rainfall totals through the event will vary sharply
from south to north, from 3 to 5 inches near the coast to less
than 1 inch in parts of SE Alabama and SW Georgia. In addition,
localized higher amounts are possible south of I-10, where Flash
Flooding cannot be ruled out.

.LONG TERM [Monday Through Friday]...
Even as Cristobal moves quickly to the north and east next week,
the area is expected to remain in a fairly moist and tropical
airmass. This will keep PoPs at or above typical summertime
levels. Expect highs in the upper 80s to lower 90s and lows in the
lower 70s.

Winds and seas will begin to increase tonight as Tropical Storm
Cristobal moves into the central Gulf of Mexico. Expect poor
marine conditions to last into Monday, with the worst weather
expected late Saturday into Sunday.

No fire weather concerns through early next week.

See short term discussion above for rain and surge impacts
associated with Cristobal. In short, isolated flash flooding will
be possible along the north Florida coast on Sunday, with minor to
moderate level coastal flooding expected as well.


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
calling the office or tweeting us @NWSTallahassee.
