DISCUSSION...Updated for latest aviation discussion below.

the day around 10kts. Isolated to scattered late am into early
afternoon tsra along the terminals with storms more inland thru the
course of the afternoon. /10

PREV DISCUSSION... /issued 449 AM CDT MON AUG 15 2016/

NEAR TERM /Now Through Monday night/...Upper air weather map
analysis this morning shows a strong mid-level Bermuda ridge of high
pressure extending west into the southeast US. A well defined mid-
level trough axis off the western FL Panhandle was spinning
northwest. In the lower levels of the atmosphere, ridge of high
pressure was well established from the southeast US into the
southwest Atlantic. Quasi-stationary surface front was draped from
the New England States to the Ohio River Valley and extends southwest
from there to eastern TX. Deepest layer moisture is highest along the
frontal zone, down into the western Gulf. With the deep layer ridge
axis to the east, wind profiles with height show a well established
south to southeast flow over the forecast area, which keeps Gulf
moisture opened up and sufficient for scattered showers and storms
today. Although the mid-level trough off the western FL Panhandle is
forecast to deamplify as it moves west-northwest today, this feature
also brings potential of enhanced ascent for storms.

Along the beaches, persistent southeast flow, spring tidal cycles
and swell moving up into the surf zone favors a high risk of
dangerous to potential deadly rip currents today.

Today's high temperatures range from 90 to 93 interior 87 to 90
closer to the beaches. Overnight lows near 73 inland to upper 70's
beaches. /10

SHORT TERM /Tuesday Through Wednesday night/...The upper level ridge
of high pressure extending from the western Atlantic Ocean over the
southeast conus will weaken and shift south through midweek as a
series of upper level shortwaves move east over the great lakes
region and northeast conus. Meanwhile the surface ridge extending
from the western Atlantic across the southeast will weaken slightly
and shift a little south as well. Precipitable water values across
the region will remain between 1.5 and 2 inches. A mix of sun and
clouds will occur on both Tuesday and Wednesday, with the diurnal
convective pattern persisting. Expect mainly scattered coverage
during the daytime hours and isolated coverage to rain-free
conditions overnight through the short term.

High temperatures both Tuesday and Wednesday will range from 90 to
95 degrees inland area with upper 80s along the beaches. Low
temperatures both nights will be in the low to mid 70s inland area
with upper 70s along the beaches. /22

LONG TERM /Thursday Through Sunday/...A series of upper shortwaves
will continue to advance eastward over the northern U.S. As a result,
the upper ridge of high pressure over the southeast states will
continue to shift southward over the northern Gulf of Mexico. The
surface ridge extending from the western Atlantic across the
southeast will shift southward as well, and extend from the Bahamas
across south Florida into the eastern gulf by the end of the week.
Scattered showers and thunderstorms will occur each day through the
extended as the high pressure weakens across the region, with
isolated to scattered coverage at night. High temperatures each day
will range from 88 to 93 degrees inland area with mid 80s along the
beaches. Low temperatures each night will range from 72 to 77 degrees
inland area with upper 70s along the beaches. /22

MARINE...A light, to at times moderate southeast flow is forecast to
continue through the middle of the week with high pressure positioned
to the east of the local area. A decreasing trend in seas is forecast.
Scattered storms today will bring locally higher winds, waves and
seas at times. Moving into the remainder of the week, chances of
storms will be small. /10
