Lightning Strike in Georgia, July 12, 2012

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
ISSUED BY NATIONAL WEATHER SERVICE MOBILE AL
343 PM EDT Thu Jul 12 2012

.SHORT TERM...[Tonight through Sunday night].

The upper trof oriented along the lower Mississippi river valley
retrogrades somewhat into the southeastern Plains through Saturday
as upper ridging builds into the southeast states. Abundant gulf
moisture in place over the area with precipitable water values
near 2-2.2 inches will see a modest decrease to 1.7 to 2 inches by
Saturday due to correspondingly modest subsidence with the upper
ridging. A weak stationary front currently extending from eastern
Texas northeastward to eastern Tennessee retreats westward and
weakens through Saturday as surface ridging over the east central
states builds into the southeast states along with the upper
ridging. For Friday...a weak inverted trof...an eddy in the
easterlies...will move across the northern Gulf and combine with
the sea breeze to produce enhanced convective development in the
deeply tropical airmass over the region. Will have pops increasing
to likely over the western portion of the area with chance pops
elsewhere...then pops decrease overnight to low end chance/slight
chance. The inverted trof works further inland mainly into
Louisiana and Mississippi through Saturday with the forecast area
left with the sea breeze as the primary forcing mechanism. Will
have good chance pops over the western portion of the area...where
deep layer moisture is highest...tapering to low end chance pops
over the eastern portion. A vigorous shortwave system meanwhile
advances across the northern plains and into the Great Lakes
region on Sunday...and phases with the southeastern Plains upper
trof. The combined upper trof then advances to the lower
Mississippi river valley again Sunday into Sunday night with
ridging over the southeast states retreating into the western
Atlantic. Precipitable water values will be slightly below
normal...near 1.5 inches...due to modest subsidence from the
retreating upper ridge. The surface ridging over the area weakens
meanwhile and shifts southward to be oriented along the coast
maintaining a light southerly flow over the forecast area. The sea
breeze remains the primary forcing mechanism for the most of the
area again on Sunday and will continue with chance pops. The
potential for severe storm development continues to be low through
the period though convection that does develop will have the
potential for locally heavy rainfall thanks to the deep tropical
airmass over the area along with gusty winds and frequent
lightning. Temperatures will be near seasonable levels on Friday
then slightly above seasonable levels Saturday and Sunday. /29

&&

.LONG TERM...[Monday through Thursday].
The phasing of the weak upper trof over the lower Mississippi river
valley and the northeast states shortwave trof breaks down on Monday
with the northern system exiting into the Atlantic.  The weak upper
trof retreats westward Tuesday into Wednesday into the Southern
Plains with modest upper level ridging building into the southeast
states.  A longwave trof begins to amplify over the northeast states
on Wednesday...and builds into the southeast states on Thursday.  A
surface ridge oriented along the northeastern Gulf coast moves into
the northern Gulf by Thursday as a trailing cold front...associated
with a Canadian system moving off into the Atlantic...moves
gradually southward into the Gulf coastal states.  At this time the
front looks to remain north of the forecast area but convective
development may be enhanced over the northern portion of the area.
Otherwise...a light southerly flow will continue over the area with
the sea breeze as the primary mechanism for convective initiation.
Deep layer moisture improves over the area on Monday to near 1.9
inches and remains close to this through Thursday.  Temperatures
will generally be near seasonable values through the period. /29

&&

.AVIATION...
[18Z taf issuance]...scattered convection is ongoing across the
Florida panhandle and will continue to progress inland through the
early evening.  Outside of the showers and stores...vfr conditions
will prevail with light southerly to southeasterly winds.  If the
East coast sea breeze progresses westward fast enough...the
easternmost taf sites could experience another rough of storms
early this evening. Fog and mvfr conditions will be possible and
the northern tier of taf sites early Friday between 10 and 14 UTC.
07/MAB.

&&

.MARINE...
Surface high pressure over the western Atlantic noses westward into
the southeastern U.S. resulting in a light onshore flow and small
sea states through the period.  Winds...waves and seas locally
higher in and near storms.  Will keep the possibility of waterspouts
due to the very moist environment and light winds. /10

&&

.FIRE WEATHER...
A moist southeasterly flow will continue over the area through the
weekend.  Afternoon relative humidities will remain well above
critical levels with scattered to occasionally numerous showers and
thunderstorms. /29
