Short term
Advection of dry cool air will continue through Wed and stabalize
Thursday. Winds will veer around to the east Thursday and
southeast by Friday. This will help to bring some moisture back to
the area starting Friday, but the moisture advection will be a
rather slow process as dew pt temps will struggle to get back to
the mid 60s by the weekend just ahead of the next cold front. The
front should move through Saturday night into Sunday morning. The
front does not look to cleanly push through as the subtrop jet
will keep moisture lifting over the boundary into the cooler air
behind the front. A sfc low may form along the boundary over the
gulf and lift northeast. At the moment, there is no confidence in
the placement of this low and where it approaches the coast. But
this should be somewhere between the new oreans area and tampa
bay Monday or Tuesday of next week. The weekend into early next
week will be the only focus for meso or synoptic scale weather
impacts.

Aviation
Cold front has moved south of all terminals. All terminals currently
vfr. Only two real concerns for the 12z package. First is whether
clouds over northern half of mississippi continue to sink southward
toward kasd and kgpt later this morning. These cold advection
stratocumulus clouds are based around fl025, give or take a few
hundred feet, so MVFR ceilings are not out of the question. Looks
like it will be a close call around 16-18z, but current indications
are that the clouds will get shunted eastward just as they arrive in
the area. Second will be northerly winds due to cold advection at
knew and kmsy. Some potential for gusts to 20 knots during the
evening hours tonight, primarily at knew. 35

Marine
Cold front has moved through most of the coastal waters this
morning. Seeing a brief increase in winds over the coastal waters.

Certainly will need exercise caution headlines over the outer waters
today, but question is over the inner waters and tidal lakes and
sounds. Right now, it appears that 15 knots may hold the for the
lakes, sounds and inner waters, and will hold off on headlines
there. A secondary push of colder and drier air will arrive this
evening and likely will need headlines tonight for most or all
waters. Winds should ease during the day on Wednesday.

Conditions should then be quiet through at least Saturday. Beyond
that, quite a bit of difference in medium range model guidance. Have
opted toward a blended solution which fits with most neighbors. Will
note that the GFS solution is significantly more windy from Sunday
onward as it tracks a fairly healthy surface low across southeast
louisiana. This solution appears to have been favored by the ocean
prediction center for the middle gulf of mexico, but we are
consistent with wfos mob and lch. This is beyond the 5 days of the
marine forecast package, so there is time to make adjustments if
necessary. 35

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
