Synopsis
A weak area of high pressure will be across the area through the
weekend into next week. Moisture will increase through the first
half of next week, as a bermuda high strengthens over the western
atlantic ocean.

Near term through Sunday
As of 7:45 pm: convection has ended across most of the fcst area
with the exception of a large cluster of thunderstorms over union
county, sc. This activity should die off over the next couple of
hours as instability wanes and any lingering outflow boundaries
dissipate.

Otherwise, not much change in the air mass or overall pattern is
expected on Sunday, with weak W SW flow aloft and a nebulous surface
pattern, with the old frontal boundary focusing convection closer to
the coast. Mid-level lapse rates will remain respectable, perhaps
even improve a bit, and strong insolation and seasonable dewpoints
will yield another round of moderate-to-strong instability. Deep
convection should again fire across the usual high terrain areas
during early afternoon, and 30-50 pops are carried across much of
the mtns. At least isolated outflow-driven convection will waft into
the piedmont again by late afternoon, warranting 20-40 pops there.

Max temps will again by a few degrees above normal.

Short term Sunday night through Monday night
As of 200 pm edt Saturday: mid level heights will start out in a
westerly flow pattern Sunday night and Monday. By Tuesday, there
will be mid level ridging centered across the southern plains and
over the atlantic ocean near bermuda. A weakness between the two
ridge centers will exist across the southeastern states allowing for
a more active convective pattern to develop starting on Tuesday.

High temperatures will be in the lower 90s in the piedmont and mid
to upper 80s in the mountain valleys on Monday. However, with
increased moisture and convection, highs will be a few degrees
cooler on Tuesday.

Long term Tuesday through Saturday
As of 200 pm edt Saturday: the medium range still looks fairly
unsettled, as a weakness in the upper level ridge lingers over the
region thru midweek. High moisture content as indicated by
precipitable water values approaching 2 inches by late week suggest
that some locally heavy rain will be possible by late next week.

Temperatures will be near to slightly below climo due to increased
cloud cover and rainfall potential.

Aviation 00z Sunday through Thursday
At kclt and elsewhere: expect mostlyVFR conditions thru the 00z taf
period. Over the past couple of hours, convection has been dwindling
across the fcst area from roughly north to south with some lingering
thunderstorms still firing up over parts of the upstate. This activity
should die off over the next few hours as instability wanes. Fog and or
low stratus is expected to develop again over the usual mtn valleys and
perhaps across the piedmont tomorrow morning. However, restrictions
have had difficulty developing at the TAF sites (except for very brief
periods). Thus, I kept the fcstVFR for now, hinting at restrictions
with 6sm at kclt, kavl, and khky. Otherwise, light and vrb winds will
continue thru tonight and into tomorrow, and then pick back up from
the south by tomorrow afternoon. Tomorrow's convective chances look
similar to today's, so I kept a prob30 for tsra at each site for the
19 to 24z timeframe.

Outlook: moisture and instability will gradually increase through
the middle of next weak, resulting in a steady uptick of afternoon
evening convective coverage each day, especially during the middle
part of the weak as a cold front approaches from the northwest.

Morning fog and low stratus will be possible each day across the
mountain valleys.

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.
