18z issuance... Latest satellite pix showing the development of
fair weather CU to open up the period with bases around 3 kft.

There could be some spotty mid afternoon convection along the
i-10 corridor but due to the isolated occurrence, will hold off
mentioning in the 18z forecast. Light northeast winds become more
southeast thru the afternoon. 10

12z issuance...VFR conditions will prevail through the forecast
period with scattered low clouds above 3000 feet developing late
morning into early afternoon. Added vicinity showers at all the
taf sites mid to late afternoon as a seabreeze pushes inland. A
light north wind this morning will becoming light and varible at
mob and pns by late morning ahead of the seabreeze. South winds
around 6 knots are forecast for pns after 20z in the wake of the
sea breeze. Winds at bfm will become east then southeast as a bay
breeze pushes inland. Mostly clear with light winds overnight. 22
prev discussion... Issued 414 am cdt Wed sep 19 2018
near term now through Wednesday night ... A weak upper level
shortwave over southeast alabama, southern georgia, and north
florida will drop south and then west across the northeast gulf of
mexico as it gets wrapped around the southern periphery of a
large upper high pressure system drifting east across the
southeast conus. A weak east-west surface boundary draped across
the forecast area will continue to dissipate over the next 24
hours as a surface high pressure ridge over the eastern conus
strengthens slightly as it nudges eastward.

The high pressure pattern will suppress much of the convective
activity today with only a few showers and thunderstorms popping up
along the i-10 corridor this afternoon as a sea breeze pushes
inland. Strong insolation throughout the day will allow surface
temperatures to rise into the low to mid 90s, and when combined with
dewpoints in the lower 70s will result in heat index values ranging
from 100 to 105 degrees. Dry conditions are set for the overnight
hours. 22
short term Thursday through Friday night ... An upper ridge
pushes east over the eastern seaboard through the short term, with
the center of the anticyclone located over northern al ga on
Thursday and the carolinas by Friday. As this ridge shifts east of
the area, a weak upper low over the western atlantic begins to
push westward along its southern periphery and over the florida
peninsula. The local area remains beneath the southwestern
periphery of the upper high over the carolinas, leading to
southeastern flow off the gulf and increasing deep layer moisture.

As a result, expecting to see an uptick in thunderstorm activity
along the sea breeze on Thursday, particularly over the eastern
half of the area where moisture levels will be better and
subsidence weaker. High temperatures reach the low to mid 90s with
heat indices around 100 to 105 degrees.

Better rain chances return areawide on Friday as the upper low
over the florida peninsula continues to creep west and upper
support improves along its western periphery. Have chance pops in
there right now across much of our area, mainly 30-40% with
scattered coverage expected. Showers and thunderstorms should
develop offshore and near the coast during the morning hours and
spread inland throughout the day. High temperatures reach the
upper 80s to low 90s. 49
long term Saturday through Tuesday ... A large upper high
centered over mexico shunts the upper low over the eastern gulf
southwest, where it meanders over the southern gulf for a few
days unable to advance any farther west. In its wake, a weak ridge
builds from the western atlantic into the southeastern states and
lower mississippi river valley. Beneath this ridge, only isolated
to widely scattered showers and thunderstorms are expected
Saturday and Sunday. Better rain chances and coverage would be
limited to the western half of the area where the ridge, and
associated subsidence, will be somewhat weaker.

While this is all happening down here in the subtropics, a broad
upper trough in the mid-latitudes begins to develop over the
central CONUS as a series of vigorous shortwaves dig southeast
from the canadian rockies into the northern plains. This sets up a
deep, moist southwest flow over the local area early next week.

Weak shortwaves embedded within the southwest flow bring greater
rain chances to the local area Monday and Tuesday. Going forward,
the GFS and ECMWF are now in better agreement developing a
surface low in the lee of the central rockies during the middle
part of next week. As this low lifts quickly northeast towards the
great lakes, it drags a cold front southeast across the plains
and mississippi river valley. How far southeast this front reaches
will depend heavily on how deep the upper trough and associated
surface low become, something which is tough to forecast with much
confidence this far out. That said, this pattern could be setting
the stage for our first decent frontal passage of the season late
next week. 49
marine... A weak surface ridge of high pressure over the northern
gulf will become reinforced from the north later in the week. A
light offshore flow this morning will be followed by a light to
occasional moderate east to southeast flow Thursday through Sunday.
