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 evening's balloon launch was successful with no issues
encountered. Interesting features on this sounding profile
includes a rather dry moisture profile aloft, with pw of 1.37
inches ranging below-normal for this time of the year according
to sounding climatology. The boundary layer thermal and moisture
profile was well-mixed this afternoon, with a prominent subsidence
inversion between 800 and 850mb which helped suppress area-wide
convective thunderstorm development today. Otherwise, the vertical
wind profile was relatively calm for the most part up to 400mb,
before winds picked up at around 25-35kts from the SW to the
tropopause. Sharp moisture increase right at 300mb looks like the
radiosonde traveled through some patchy high-level cirrus down
wind of the station. Klg

Short term (tonight through Tuesday night)
A deep layer ridge, extending from near florida across the gulf
of mexico and north gulf coast today, will gradually become
centered a bit north Sunday into Tuesday with the mid to upper
level high center expected to be over the interior southeast
states lower mississippi valley region Monday and Tuesday. This
will deflect systems in the westerlies well north of the forecast
area, and any wave features or deeper moisture in the tropical
easterlies should remain well to the south. The only source of any
showers and thunderstorms in this pattern is the strong diurnal
heating combined with available moisture and low level convergence
boundaries. This was largely absent today except for a couple
brief light showers here and there due the capping effects of a
warm nose in the 850-750 mb layer that was observed on the 12z
lix sounding. The westerly winds in this capping layer should back
to southerly then easterly over the next couple days, so that
should allow for a bit more coverage of showers and some
thunderstorms over the next few days, although am only expecting
pops of 10-20% on Sunday and 15-25% on Monday and Tuesday.

Daytime highs may start to nudge up from the lower 90s to some mid
90s in warmer inland locations, but the lows should be able to
lower from the last couple very warm nights due to the lighter
winds that are expected. The combination of heat and humidity will
continue to push heat index values up into the 100 to 106 degree
range each afternoon which would remain below heat advisory
criteria.

Long term (Wednesday through Saturday night)
Little change in the overall pattern is forecast going through
Thursday with deep layer high pressure in place, except the
typical seabreeze and lake breeze regime may be sufficient for
slightly higher rain chances (20 to 30%). Still expect hot high
temperatures in the lower to mid 90s.

Heading through the latter part of the week, the deep layer high
is expected to push very slowly west across the lower mississippi
valley while a broad mid upper low moves west over the eastern
gulf coast florida panhandle. This should bring some higher
precipitable water nearing 2 inches over eastern portions of the
forecast area on Saturday. Rain chances should start to go up
over the mississippi gulf coast during the Friday to Saturday
periods while other locations to the west continue to experience
only isolated to low scattered coverage of showers and storms.

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...

vfr conditions are expected through 09z Sunday across the
terminals. Cannot rule out a few hours of MVFR ceilings again
around around 12z Sunday. These conditions would improve by 15 or
16z Sunday. 18

Marine
Cannot rule out a few observations possibly reaching exercise
caution criteria this evening, but think most sustained winds should
remain below 15 knots. Beyond tonight, expect relatively quiet
conditions on the waters with flow generally becoming diurnally
driven. 35
