Sounding discussion
The column is generally quite moist with a pwat of 2.23 inches,
around the same as the past 2 days, with a prominent dry slot
around 450mb. It is also above the daily mean of 1.88 inch for
this day. MLCAPE at 1883 j kg and relatively low convt indicates
storms should have no problem forming given sufficient forcing.

Cin is present at the surface (-150 j kg) but will likely erode
quickly as temps warm up. Winds are generally light throughout the
column, with the surface at about 15 knots wsw. It speeds up to
25-30 knots and becomes mostly southerly near the top.

short term...

old outflow boundaries exist in most locations this morning. This
can act to initiate sh TS and should be able to do so today once
heating begins. Should still get a crop of sh TS moving in from
the gulf during the morning, maybe not as many as yesterday.

Thunderstorms today through much of the upcoming week will be
capable of very heavy rainfall in a short period causing some
flooding of low lying and poor drainage areas and roadways will
definitely make that list.

Guidance is still advertising a cold front to move into the area
by mid week dropping temps down into the mid to upper 80s with no
dense cloud cover. For this time of year, that is relatively
strong cool air advection. Dry air will also accompany the front
bringing dp temps back down to the mid 60s. This would only last a
day maybe two at the most around wed. The moisture surges back to
the north once again by the end of the work week bringing the
warmth, humidity and sh TS back to the area.

By next weekend, deep easterlies will develop again and at least
one if not two easterly waves will bring a better chance of sh ts
to the area possibly by the end of next weekend or into the new
week. Easterly waves affecting the area are very normal for
august but an actual cold front with cooler temps is not but we
will take it.

Aviation...

forecast scenario is little changed from the past several days.

ExpectVFR conditions to predominate through the forecast period
outside of convective activity. A little less convection noted over
the coastal waters at 08z compared to the past 2 mornings, so pre-
dawn convection may not be quite as common as the past 2 mornings.

Will tend to use vcts with only a 4 hour window of tempo in most
terminals today, as instantaneous areal coverage of convection may
not be much more than 30-40 percent. If convection is expected to
directly impact a terminal, ifr or lower conditions will be
possible, with wind gusts to 30 knots or so. Most convection should
run out of steam around 00z-01z, with a restart of coastal
convection Sunday morning around 10z. 35
marine...

high pressure will remain centered east of the waters through early
next week. As a result, a prevailing onshore flow of 5 to 10 knots
is expected across most of the coastal waters through the period.

The only exception will be over the nearshore waters off the
mississippi coast where a seabreeze is expected to develop each day.

This could induce some stronger onshore winds of 10 to 15 knots for
a few hours each afternoon across the mississippi and chandeleur
sounds. Seas will range from 1 to 2 feet through the entire period
across all of the waters. Medium range models do depict at least a
brief period of northerly winds late Wednesday with a cold frontal
passage, but no strong winds indicated with this frontal passage
outside of convection. 35
