GMZ600 Synopsis For Destin Fl To Pascagoula Ms Out 60 Nm Including Mobile Bay- 439 Am Cdt Sun Aug 20 2017
Synopsis..A surface high pressure ridge will build in from the east on Sunday and persist into the middle part of the week. This pattern will result in a variable light wind flow pattern today becoming more east to southeast through midweek. A weak frontal boundary is expected to approach the marine area late in the period with winds remaining light but possibly becoming more west to southwest. Little change in seas expected through the period. Winds and seas will however be locally higher in and around isolated to scattered showers and Thunderstorms.

Sounding discussion
Routine flight terminated over southwest lake pontchartrain at a
height of 104,000 feet, or 19.7 miles above the surface.

Some drying has occurred with the precipitable water value down to
1.89 inches, which is slightly above average for late august.

Forecast CAPE is just over 2400 j kg with a lifted index of -6.

Mid level lapse rates are around 6.2c km. Downdraft CAPE is 671
j kg, which is quite a bit lower than yesterday. Convective
temperature is 89 degrees, so it'll be a few hours before things
start percolating. Freezing level this morning near 15,000 feet,
with a -20c level at 27,400 feet and wet bulb zero near 13,000
feet.

Winds in the lower levels were rather light this morning,
generally less than 10 knots until nearly 500 mb. Easterly winds
between 500 and 400 mb, then northerly from 350 mb to 100 mb. Max
wind of 40 knots was measured at 34,000 feet. 35

Decision support
Prev discussion issued 335 am cdt Sun aug 20 2017
short term...

a temporary reprieve from numerous showers and thunderstorms is
likely to take place today across the forecast area. Upper level
analysis shows a weak ridge centered through east texas and northern
louisiana with a trough moving east across the northeastern conus.

The ridge will slide across the CWA today as it is absorbed by a
more dominant western atlantic high pressure that will be extending
into the southeast us. Increased subsidence in combination with
strong mid level drying (pw dropping to 1.7" per model soundings)
will significantly limit convective development. Therefore, have
dropped pops down to 20-30% for today and that may be generous.

Long term...

the upper ridge centered in the western atlantic will generally
remain in place through early next week. A tutt low, currently seen
on WV moving west across the eastern gulf of mexico, will be
tracking west across the gom Monday. This movement will erode a
portion of the ridge over the CWA and in combination with daytime
heating will enhance convection. Expecting rainfall coverage to jump
back up to around 40%. A repeat looking likely again on Tuesday as
synoptic changes will be minimal. A slight increase in column
moisture will promote more numerous convection.

Moving into the mid and latter half of the week, models show a broad
long wave trough dipping out of canada and tracking across the
appalachian mountains. A weak cold front associated with this trough
will slowly sag into and stall across the region. It will become the
focus for continued daily rainfall, with pops likely 50% or above
through Friday.

Meffer
aviation... Tsra will show less coverage today. There
will not be enough probability to include in this TAF cycle.VFR
conditions should be the prevailing conditions.

Marine... No changes as high pressure remains the dominant
factor over the northern gulf. Diurnal fluctuations will remain the
main driver of winds. Most nights, look for a weak enhanced jet over
the waters east of the ms delta where winds could bump up to near 10
knots. Seas will remain around 2 ft or less.

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