...A SEVERE THUNDERSTORM WARNING REMAINS IN EFFECT UNTIL 500 PM EDT
FOR NORTHEASTERN FRANKLIN...SOUTHEASTERN STEPHENS AND SOUTHWESTERN
OCONEE COUNTIES...

At 429 PM EDT, a severe thunderstorm was located 10 miles east of
Toccoa, or 5 miles northeast of Avalon, moving southeast at 20 mph.

HAZARD...60 mph wind gusts and quarter size hail.

SOURCE...Radar indicated.

IMPACT...Minor hail damage to vehicles is expected. Expect wind 
         damage to trees and power lines.

Locations impacted include...
Westminster, Gumlog, Tugaloo State Park, Oakway and Lavonia. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A few trees and power lines will be blown down in the warned area.
Hail can cause major property damage, especially to vehicles. Seek
shelter inside an interior room.

This storm is producing frequent and intense lightning. Turn off
electrical appliances. Do not use corded telephones. Do not take a
bath or shower.

Lake Hartwell is in the path of this storm. Get away from the water 
and seek shelter in an interior room in the nearest shelter. If you 
can hear thunder, you are close enough to be struck by lightning.

Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
257 PM EDT Sun Jun 3 2018

.SYNOPSIS...
A well-deserved drier and seasonably warm airmass arrives to begin
the work week.  Only isolated showers and thunderstorms are expected
on Wednesday as a cold front settles into the area from the north.
Drier and seasonable conditions return for Thursday behind the
front before temperatures, humidity, and chances for showers and
thunderstorms increase Friday through Sunday as another cold front
approaches the region.

&&

.NEAR TERM /THROUGH MONDAY/...
As of 255 PM Sunday: Another warm day has evolved across
northeast GA and the western Carolinas, as latest obs are
showing temperatures well into the mid to upper 80s. With an
upper trough moving across the Great Lakes region and it's
associated cold front draped down through eastern KY/TN and into
AL/LA, expect another late afternoon/evening of isolated to
scattered convection as the front propagates from west to east
this evening into tonight. Latest radar imagery already shows a
few isolated showers and thunderstorms that have developed
across the mountains and Upstate within the past hour. With
continued downslope flow, a developing leeside trough, SB CAPE
1500-2500 J/kg, steep low level lapse rates and 0-6km bulk shear
up to 30 kts across portions of the area - the potential for a
few severe thunderstorms will continue across the western half
of the CWA into early this evening.

With the loss of daytime heating, expect convection to wane as it
nears the I-77 corridor this evening, though would not entirely rule
out a few showers/thunderstorms reaching the CLT area before all is
said and done. The cold front will push through tonight, allowing
for drier air to infiltrate in with sfc high pressure building in
from the west for the beginning of the work week. Expect Monday will
be the first rain-free day that we've seen in awhile across the area
with plenty of sunshine and temperatures around to just above normal.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
As of 230 PM Sunday: Dry and comparatively cool weather is
expected to continue through the first half of the short term,
as an upper trough axis persists along the East Coast. A weak
boundary dropping into the area from the north on Wednesday may
provide a focus for some isolated diurnal convection, although
guidance is in rather good agreement that moisture and
instability will be difficult to come by. Temps will be near to
slightly below normal through Tue night, warming to slightly
above normal Wed afternoon.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/...
As of 245 PM Sunday: By Wednesday evening, the longwave trough
axis will be east of the region with the post-frontal surface high
pressure center moving off the Mid-Atlantic coastline.  The surface
ridge axis will settle across the area into Thursday while heights
gradually build aloft as the Southern Plains heat ridge slowly
builds eastward.  Weak low-level flow and the upper-level ridge axis
overhead should work to limit convection on Thursday, and while the
official forecast keeps the area completely dry per the ECMWF and
Canadian solutions, the GFS is a little faster in veering surface
winds SEly and advecting enough flow and moisture to trigger some
afternoon convection.  Nevertheless, high temperatures are expected
to near normal on Thursday before the airmass begins to modify as
the upper-level ridge axis strengthens and southerly flow returns.
This should allow isolated to widely scattered diurnal convection
to return for Friday afternoon as a strong shortwave drops into
the Midwest embedded within the NW flow aloft.  The associated
cold front will sag into the Ohio Valley on Saturday as a repeat
convective performance is expected across the area; however,
by Sunday, moisture pooling ahead of the front combined with the
proximity of the front and aforementioned shortwave energy will
bring better chances for showers and thunderstorms across the
region.  At this time there is decent model agreement on dropping
the front into the area from north to south near the end of the
period or Monday morning.  In the meantime, given the pattern,
high temperatures will be slightly above normal for the weekend
with increasing humidity.  As dewpoints approach 70 degrees,
low temperatures, therefore, will become somewhat uncomfortable
Friday night through Sunday night.

&&

.AVIATION /19Z SUNDAY THROUGH FRIDAY/...
At KCLT and elsewhere: VFR prevails at all TAF sites this
afternoon with WNW winds and a healthy, growing CU field across the
FA as seen from latest satellite imagery. With a cold front draped
down through eastern TN/KY and back into NW AL, convection has
already begun to fire along this boundary. Expect this activity to
move from west to east as the cold front begins pushing across the
FA later this afternoon, starting within the next few hours. Expect
convection will wane into the evening hours as it approaches KCLT
around 01/02Z. Flight restrictions may briefly drop to MVFR in any
heavy downpours/stronger storms that move over a TAF site. Behind
the front, VFR will prevail through the remainder of the valid TAF
period as NW/downslope winds will persist with drier air
infiltrating in. Sfc high pressure building in from the west will
dominate the weather pattern through at least Monday evening. With
elevated boundary layer winds, do not anticipate fog development
overnight.

Outlook: Increasing chances for VCSH/VCTS towards the end of the
week. Otherwise, expect VFR.
