.PREV DISCUSSION... /issued 713 PM CDT Mon Sep 25 2017/

DISCUSSION...
For 00z TAF issuance.

AVIATION...
Local 88Ds show diurnal convection just about coming to an
end...have allowed VCSH to continue for the next hour or so across
the srn sites to account. Thereafter the main issue for the rest
of the night remains fog potential...although restrictions to
visibility weren`t a big deal this morning, have elected to
maintain the inherited TEMPOs for light fog for late tonight due
to recent persistence and climatology. For tomorrow, am only
carrying any precip (and only a VCSH at that) for the Acadiana
terminals where moisture will be best.

PREV DISCUSSION... /issued 358 PM CDT Mon Sep 25 2017/

DISCUSSION...Weak ridging at the surface and aloft remains in
place across the northern gulf coast. A relatively dry air mass is
in place as well, however isolated showers and storms have
developed along the sea breeze. also, an upper trough is located
across the western half of the country.

Through mid week the pattern will remain stagnant locally with
isolated to possibly scattered storms possible. Through mid week
a short wave will move through plains eroding the upper ridge and
sending a cold front through the region by Thursday. The boundary
Thursday is expected to be more of a wind shift line, however the
short wave will deepen Friday and into the weekend finally
sending a more seasonable and less humid air mass into the area.

The return flow will begin early next week.

MARINE...A light to moderate east to southeast flow will remain
in place through Thursday. Northeast winds will increase Friday
behind the front.
