508 pm cdt Fri oct 18 2019

Short term (tonight through Sunday)
Main change this forecast issuance is to drop the tropical storm
warning for land areas. Tropical storm nestor, which was named
with the 1 pm advisory today, is forecast to have it's center move
just beyond the 60 nautical mile coastal waters ring tonight
before reaching the florida panhandle coast near apalachicola
early Saturday morning. This is expected to keep the tropical
storm force winds over the coastal waters where the tropical
headlines remain in effect. The heavier rain is also expected to
remain mostly offshore with mainly light to occasionally moderate
rain expected over mainly coastal areas. The main concern through
the next high tide cycle later on tonight into early Saturday
morning will be minor coastal flooding with inundation of 1 to 2
feet expected in the lowest lying areas near the coast and
lakeshore. Flooding has already occurred near the time of high
tide in portions of st. Tammany parish and hancock county this
morning, and mdl extra-tropical storm surge guidance indicates a
rise of .5 to .75 feet compared to the high tide cycle earlier
today. It is possible these values may be overdone since winds are
shifting around to more northerly tonight, but minor coastal
flooding is still likely.

Surface high pressure will take hold over the weekend which will
result in dry and pleasant conditions with abundant sunshine on
Saturday and partly to mostly sunny skies on Sunday. The
mid upper level flow pattern is expected to be zonal then
southwesterly across the forecast area as a large and potent
shortwave trough moves through the rockies into the central and
southern high plains region. Temperatures will warm quite a bit
compared to today and return to near normal for highs Saturday and
above normal on Sunday.

Long term (Monday through Thursday)
The larger scale shortwave trough will move east through the
plains into the mississippi valley region Monday and Monday night
with the associated cold front pushing east into and through the
forecast area. There will be ample moisture, shear and instability
for fairly widespread showers and thunderstorms with potential for
some strong to severe thunderstorms. Monday currently has a 15%
probability severe area outlooked by storm prediction center
across portions of the deep south with the southern portion
extending into the southwest mississippi counties. Will likely see
some fine tuning of this outlook and a larger "marginal" risk
area for the 5% severe probability area when the new day 3 outlook
for Monday Monday night is issued late tonight.

Cooler and drier weather will follow the cold frontal passage
Monday night through Thursday with the next system bringing
another round of showers and thunderstorms Thursday night into
Friday. 22 td

Aviation
Vfr conditions prevail at all area airports. Vicinity showers
with wind shifts greater than 30 degrees and gusty winds are
likely along the coastal airports this afternoon into the evening
hours, especially hum and gpt. These vicinity showers could cause
temporary lower CIGS and visibilities, as well. Msw

Marine
Tropical storm nestor will move northeast across the
north central gulf of mexico tonight, just beyond 60 nautical
miles offshore from the mouth of the mississippi river and
mississippi coast, before reaching central florida panhandle early
Saturday morning. Tropical storm conditions are expected across
most of the coastal waters as nestor moves northeast tonight and
early Saturday. Conditions will improve from the west Saturday
through Sunday as high pressure builds into the central gulf
coast region.

A potent storm system and cold front will move approach and move
through the coastal waters Monday and Monday night. Fairly
widespread showers and thunderstorms are expected to occur ahead
and along the cold front, and some strong to severe thunderstorms
could occur. Southerly winds are expected to rise to near 15 knot
at times ahead of the front late Sunday night into Monday then
shift to north to northeast 15 to 20 knots behind the front late
Monday night though Wednesday morning. 22 td
