658 pm cdt Wed may 24 2017

Discussion Updated for latest marine discussion below.

Marine Latest surface data collection platforms over the marine
area indicate that wind speed has lowered to below small craft
advisory criteria for portions of area bays and sounds from
perdido bay eastward. Will replace with small exercise caution
headlines. For southern mobile bay and the adjacent ms sound,
west northwest winds remain in advisory criteria. The latest high
resolution hrrr guidance suggests that wind speeds will remain so,
there, over the next few hours and have thus extended the
advisory for these areas thru 10 pm. For the open gulf waters,
advisory remains unchanged. 10

prev discussion... Issued 355 pm cdt Wed may 24 2017
near term now through Thursday ... An upper level low pressure
system continues to propagate southward across southern mo toward
northern ar this afternoon, while a broader scale upper level trough
extends across the mississippi tennessee valleys and central gulf
coast region. A surface cold front has pushed to the east of our
forecast area this afternoon, with gusty westerly winds and lower
dewpoints in the 50s spreading across our region. While earlier
convection has moved to the east of the forecast area along and
ahead of the front, visible satellite imagery shows an agitated
cumulus field spreading into interior southeast ms and southwest al
along the trough axis, and there will still be opportunity for a few
isolated light rain showers to develop over the interior through
this evening as the trough axis moves across the region. We will
keep a 20% pop in the forecast this evening mainly north of hwy 84.

We otherwise expect clearing skies late tonight into Thursday as a
drier northwest flow aloft spreads into our region in the wake of
the departing trough axis. A building surface ridge, clearing skies
and a drier airmass will support cooler low temperatures tonight
with readings in the lower to mid 50s over most interior areas, with
upper 50s to mid 60s expected near the immediate coast and beaches.

Highs Thursday are forecast to range from around 80 to the lower 80s
across most locations. 21
short term Thursday night through Saturday night ... The pleasant
break from humidity quickly vanishes heading into the short term
period. Surface high pressure builds into the western atlantic and
onshore flow is reestablished across the central gulf coast by
Friday. Despite increasing low level moisture and cloudiness,
however, the short term remains rain free thanks in large part to
mid-level subsidence beneath an upper high parked over the
central and northern gulf. High temperatures will reach the upper
80's to low 90's inland and the mid 80's along the beaches both
Friday and Saturday afternoons. Overnight lows gradually warm
into the weekend as moisture returns to the area, with temps in
the low to mid 60's Thursday night becoming low to mid 70's by
Saturday night.

49
long term Sunday through Wednesday ... Unsettled weather returns
for much (if not all) of the long term period. A large and deep
upper-level low pressure system over eastern canada pushes the
high pressure in the central gulf farther south and east. This
shift places a more organized zonal upper-level flow over the
central gulf coast along the southern periphery of the
aforementioned canadian low. Beneath this setup, a weak frontal
boundary sags into the local area before stalling and, save for
some minor shifting due to mesoscale forcing mechanisms (e.G.,
sea land breezes), remains stationary into next week. A combination
of the stationary boundary, onshore surface flow, and a series of
impulses embedded within the upper-level flow will support daily
shower and thunderstorm activity beginning as early as Sunday
afternoon evening and lasting into the middle part of next week.

In terms of temperature, Sunday likely remains hot (upper 80's to
low 90's inland, mid 80's along the beach) before the front
enters the area. Monday through the middle of next week, however,
will see highs only reaching the mid 80's as cloud cover and
thunderstorms help to mitigate daytime heating. Low temps will
depend on the location of the stationary front each night. Sunday
night, most locations will continue to see lows in the low to mid
70's before the boundary stalls across the area. Heading into the
rest of the long term (Monday and Tuesday nights), temps north of
the stalled front will dip as low as the mid 60's. Temps south of
the front and along area beaches will continue to stay in the low
to mid 70's.

49
marine... A moderate to strong west to northwest flow will prevail
over the marine area tonight as high pressure builds into the
western and central gulf behind the frontal passage. A small craft
advisory will continue until 7 pm for area bays and sounds where
winds around 20 knots are expected before gradually diminishing this
evening. A stronger west to northwest flow and elevated seas up to 6-
9 feet will support keeping a small craft advisory over the coastal
waters through late tonight. Surface high pressure will build from
the central gulf of mexico Thursday to the eastern gulf and fl
peninsula Friday through early next week. Moderate westerly flow
Thursday should gradually become southerly to southwesterly Friday
through Monday. Seas also gradually subside late this week into the
weekend. 21
