Marine Weather and Tides
Buras, LA

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Sounding discussion
This afternoon's balloon launch was successful and without any
issues. Looking at the sounding, the atmosphere is dry throughout
the lower, middle, and upper levels. There is some CIN present in
the mixed layer parcel. The winds are mostly easterly throughout
the lower and middle levels of the atmosphere. The winds shift and
are westerly at the upper levels of the atmosphere, including at
the jet stream. Msw

short term...

mid to upper level shortwave troughs and vorticity maxima will
continue to move east to east-southeast across the lower
mississippi valley and interior southeast states through Saturday.

This is in the relatively fast westerlies to the south of the
unseasonably strong deep upper low that will start to open into a
wave and accelerate east-northeast as it moves across the ohio
valley and lower great lakes to the eastern great lakes tonight
and Saturday. There may be just enough moisture and a push of
surface outflow and cool pooling aloft to allow for some isolated
to scattered showers and thunderstorms to move or develop into
southwest mississippi and some adjacent southeast louisiana
parishes this evening. A few thunderstorms that do make their way
into extreme southern portions of southwest mississippi could be
on the strong to severe side, but more likely in a weakening state
as has been the case thus far with storms trying to push
southeast into west central mississippi. Many of the hi-res
models cams have struggled to have a handle on current radar
trends, so have relied on a combination of the previous forecast
and the 12z GFS nam runs for the pop trends. Most if not all of
the showers and thunderstorms should dissipate by 10 pm this
evening. A flat mid upper ridge will expand across the gulf coast
going into the weekend which should really inhibit convection.

Have maintained a dry forecast on Saturday and only a slight
chance of some afternoon showers and thunderstorms over some
inland areas on Sunday. The deep layer ridging will be maintained
over the southeast states and central to eastern gulf coast on
Monday as a shortwave trough moves out of the rockies into the
northern and central plains, so am only expecting isolated
afternoon showers and thunderstorms at best. The combination of
heat and humidity will push heat index values up into the 100 to
105 degree range each afternoon.

Long term...

little change in the overall pattern is forecast going through
next week, however there may be enough of a weakness in the larger
scale ridging combined with moisture pooling and the typical sea
and lake breeze boundaries to support a return to the more typical
scattered diurnal showers and thunderstorms. Confidence is not
particularly high in this transition from isolated to scattered
coverage, so there will likely be some fine tuning of these later
forecast periods. Otherwise, expect temperatures to continue near
to slightly higher than the seasonal normals which will mean heat
indices approaching 105 degrees or slightly higher on some
afternoons. 22 td
aviation...

currently, all terminalsVFR. Cumulus field has developed across the
area, but any thunderstorms development should be extremely isolated
and threat not high enough to carry in the forecast. If there is an
exception, it would possibly be kmcb, if convection currently north
of kjan and kmlu eventually sinks far enough south to affect kmcb
around sunset.

Outside of that, the only real forecast issue will be the potential
for MVFR ceilings to develop near and shortly after sunrise
Saturday. These conditions, where they develop, should improve to
vfr by 16z or so on Saturday. Again on Saturday afternoon, any
convective development is expected to be extremely isolated. 35
marine...

will carry exercise caution headlines overnight for eastern open
waters and sounds as winds increase to 15-17 knots this evening
before settling down around sunrise Saturday. Beyond tonight, expect
relatively quiet conditions on the waters with flow generally
becoming diurnally driven. 35
