Area Forecast Discussion
National Weather Service New Orleans LA
Issued by National Weather Service Jacksonville FL
343 AM CDT Mon Aug 30 2021
SHORT TERM (Today through Tuesday Night)...
What is now Tropical Storm Ida will continue to increase in
forward speed as it pushes further north into Mississippi. Despite
Ida's weakening through today, a trailing feeder band will train
thunderstorms across southeastern LA and areas east of I-55
throughout today and tonight. Strongest convergence should align
along and east of I-59 (essentially coastal Mississippi counties)
this afternoon and these locations will have the highest risk of
additional rain of 2-4 inches and localized amounts up to 5
inches. This additional rainfall will continue the ongoing flood
threat, with a Moderate Risk of Flash Flooding through tonight.
Wake trough and convergent flow will likely persist through
Tuesday night and this will keep thunderstorm and additional heavy
rainfall chances in place across the river parishes and coast.
Highs will likely only warm into the lower 80s today and the
middle to upper 80s on Tuesday. Conditions will also remain breezy
through Tuesday as a fairly tight pressure gradient lingers over
the region in the wake of Ida. Conditions should begin to improve
by Tuesday night as the system weakens and the pressure gradient
begins to loosen.
.LONG TERM (Wednesday through Saturday)...
The convergence boundary and resultant showers and thunderstorms
will continue to develop over the area on Wednesday and keep likely
POP values in place through the day. By Thursday, deep layer
northerly flow will take hold of the region and this will usher in a
much drier and much more stable airmass. Precipitable water
values will decrease to between 1.5 and 2 inches, and rain chances
will diminish to 20 percent or less from Thursday through
Saturday as strong upper level subsidence warms the mid-levels and
reduces instability. Some weak cool air advection will also
occur, and this should help with recovery and restoration efforts.
Temperatures are projected to dip into the 60s and lower 70s at
night and highs are only expected to rise into the upper 80s.
Humidity values will also be a bit lower than normal for early
September.
&&
.AVIATION...06Z TAFs
Dangerous aviation conditions from Hurricane Ida will continue
the remainder of Tonight, with gradual improvement during the day
Monday with some increase in CIGs and gradually decreasing surface
winds/gusts. Widespread rain across TAF sites will gradually
decrease to scattered showers during the day Monday as Ida tracks
slowly to the north of TAF sites. Will maintain prior forecast
trends through next 12-18 hours in 06z TAFs.
&&
.MARINE...Hazardous conditions for maritime interests continue
today as what is now Tropical Storm Ida moves inland across
Mississippi. Winds will start to ease today, but a tight pressure
gradient over the coastal waters will keep winds in the Small
Craft Advisory range (20-30 kts) through tonight. The pressure
gradient should continue to weaken on Tuesday and Wednesday as
winds should decrease to 10 to 15 knots by Wednesday night. Seas
will correspondingly decrease to 3 to 5 feet by this time. A weak
front will slip through on Thursday and winds will shift to the
north at 5 to 10 knots for the end of the week. Seas of 2 feet or
less are expected with these lighter winds.
&&
.HYDROLOGY...Surge will slowly pull back through today along
the coastal and river parishes today. However, coastal flooding will
likely continue. Moderate to Major river flooding is expected to
begin today or tonight a last through at least Wednesday on
Natalbany, Tchefuncte, Tangipahoa, Bougue Falaya Rivers. Creeks and
tributaries of the Pearl River are also expected to reach moderate
to major flood stages as well over the next 12 to 24 hours if they
haven't already.
