332 am cdt Thu aug 17 2017

Short term
Upper level analysis shows a somewhat weak ridge centered over
the northeastern gulf of mexico while a trough races northeast
across the upper mississippi river valley towards canada.

Subsidence from the high pressure aloft will limit convective
coverage today compared to previous days. Used a blend of hrrr and
gfs QPF output for pops today. Fewer storms in general, means
more opportunity to warm closer to the mid 90s. 75-78 dewpoints in
place this afternoon combined with those MAX temps will yield
heat indicies 108-110. Thus will continue previous issuance of the
heat advisory. The hottest areas will likely be along a new
orleans to baton rouge line, coincident with slightly higher
moisture along the mississippi river.

Long term
A return to a more typical wet mid august pattern is expected over
the weekend. As the previously mentioned trough moves into canada
near the great lakes, a secondary trough will dip out of canada into
the northern plains. This feature will track on a more west to east
direction, which will suppress the ridge that is currently close to
the cwa. Reducing local subsidence while strong daytime heating
persists will allow for numerous showers and thunderstorms to
develop Saturday and Sunday. Coverage should easily be in the 50 to
70% range. The presence of slight NW flow means there could be a
isolated strong storm or 2 in the afternoon hours.

An upper ridge building from az to tx will try to extend towards the
cwa during the first half of next week. Its possible that it will
push close enough to the area to bring down pops, especially in
western portions of the forecast area. For now, kept the long term
rain chances similar to the previous.

Meffer

Aviation Vfr conditions expected through this TAF cycle.

Thunderstorm probabilities are not high enough to include for any
site until Friday.

Marine High pressure will remain in place with diurnal
fluctuations being the main driver of winds. With most nights look
for a weak enhanced jet over the waters east of the ms delta where
winds could bump up to 10-15 knots at times. Seas will remain in the
2-3 ft range or less.

Dss code: yellow.

Deployed: nohsep.

Activation: none.

Activities: dss support for nohsep; monitoring convective trends
river flooding; and heat advisory.

Decision support services (dss) code legend green = no weather
impacts that require action.

visibility event.

Yellow = heightened impacts with short-fused watch, warning or
advisory issuances; radar support. Orange = high impacts; slight to
moderate risk severe; nearby tropical events; hazmat or
other large episodes.

Red = full engagement for moderate risk of severe and or
direct tropical threats; events of national significance.
