.DISCUSSION...
KEY MESSAGE 1: Unsettled weather will continue into late week,
with increasing chances of showers and thunderstorms this weekend.
Tonight: Conditions should remain quiet for much of the area
this evening and early overnight after a full day of convection
working over the environment and a loss of diurnal heating. A
bulk of the area is expected to remain dry through the night,
although HIRES guidance suggests clusters of showers and
thunderstorms returning across parts of the Southeast South
Carolina late tonight, particularly across coastal areas in the
Tri-County Area. Given PWATs around 2.0 inches, showers and
thunderstorms that develop late night could become capable of
producing brief heavy rainfall, and possibly resulting in minor
flooding issues before daybreak.
Thursday through Sunday: As this upper-lvl trough deepens
across the Ohio River Valley, a stationary front will remain
parked nearby. A couple steps forward in time, this stationary
front will become mobile and will start it`s journey
southeastward towards the region, before stalling out across our
area this weekend. This set-up combined with PWATs near 2
inches will yield daily chances of showers and thunderstorms
(esp. in the afternoon and evening hours). There is some
uncertainty regarding the coverage of these showers and
thunderstorms, however overall guidance indicates scattered to
numerous coverage each afternoon/evening. The bottom line is
that it will be a rather soggy weekend, thus the main hazard
with be heavy rainfall as there is potential for training and/or
back-building with these storms. It`s important to note that
there is increasing potential for localized flooding and/or
flash flooding this weekend esp. over urban and low-lying areas.
And again, the severe threat remains rather low with the
potential for a couple severe thunderstorms within the stronger
storms possible.
&&
.AVIATION /00Z THURSDAY THROUGH MONDAY/...
VFR conditions are expected at CHS/JZI through about 08Z
Thursday, before the risk for showers/thunderstorms increase
across the local area prior to daybreak. TEMPO MVFR conditions
between 08-11Z have been introduced at CHS/JZI to account for
this activity. SAV is anticipated to remain VFR through the
night, although some hints of patchy fog and reduced vsbys is
possible approaching daybreak. Mid to late morning hours post
sunrise should remain VFR at all terminals. However, scattered
showers and thunderstorms return during the afternoon. PROB30
groups have been introduced between 17-22Z at JZI, 18-23Z at
CHS, and 18-24Z at SAV for thunderstorms and associated MVFR
conditions.
Extended Aviation Outlook: Showers and thunderstorms will bring
brief flight restrictions through the weekend, especially in
the afternoons.
&&
.MARINE...
Tonight through Sunday: A series of stationary fronts and
surface troughs will be across the Southeast through Saturday,
potentially followed by a cold front on Sunday. Despite this
somewhat active synoptic pattern, no Small Craft Advisories are
expected, with winds generally sustained at 15 kts or less. Seas
will be in the 2-3 ft range. Additionally, thunderstorms could
briefly bring higher winds.
&&
.CHS WATCHES/WARNINGS/ADVISORIES...
GA...None.
SC...None.
MARINE...None.
