Synopsis
An upper level ridge parked over the region will continue to
provide generally fair and hot conditions through mid next week.

Near term through tonight
Hot conditions and near record high temperatures expected again
today as the upper ridge remains entrenched over the
southeastern states.

Surface high pressure also centered over the region and expect
mostly sunny skies with a strong subsidence inversion on
forecast soundings. A weak backdoor front over eastern va nc
will push closer to the forecast area this afternoon and may
provide a focus for isolated convection but the strength of the
upper ridge is expected to mute thunderstorm activity. Will
continue to advertise slight chance pops in the pee dee and
northern midlands.

Temperatures will again rise quickly and expected to top out in
the mid to upper 90s with some locations pushing into the triple
digits with record high temperatures possibly being reached or
broken. Temperatures will remain mild tonight with lows expected
in the lower to mid 70s.

Short term Sunday through Tuesday night
Relatively little change thru early next week. The upper ridge
is progged to shift a little farther south, to over the E gomex.

An upper level ripple or two along with a weak surface boundary
expected to come through with little consequence. A generally
dry atmosphere and subsidence expected to preclude significant
pops. H85 downslope flow, and associated hot conditions, to
continue. It appears that relatively dry low level air will keep
apparent temps heat index values from reaching our local heat
advisory criteria of 110f. Current forecast package includes max
heat index values up to 103.

Long term Wednesday through Friday
Upper ridge to remain centered to our south. Continued dry and
hot Wednesday. Some upper energy and a surface front and
increasing moisture progged to enter the picture late in the
forecast period. Latest model consensus indicates slight chance
pops from Thu aftn thru sat. This will also result in MAX temps
trending down some.

Aviation 12z Saturday through Wednesday
Expect mainlyVFR conditions through the 24-hour TAF period
except possible brief morning fog at ags ogb through 13z.

Ridging at the surface and aloft will provide hot and dry
conditions through the period. Convection, if any, should be
confined northeast of the terminals near a weak backdoor front
in the pee dee region. Winds will generally be light and
variable but with deep mixing winds may become prevailing west
to southwesterly after 18z.

Extended aviation outlook... No significant impacts expected at
this time.

Climate
A daily record high temperature was tied Friday at ags.

Prolonged dry and hot conditions expected, with near daily
record high temperatures possible through Wednesday. Heat index
values up to 103 expected. Please remain ALERT to the dangers
of heat and prepare accordingly.

Daily record high temperatures for columbia sc (cae) and
augusta ga (ags).

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
