Synopsis
Dry cold front will move through the area this morning then
offshore this afternoon. This will result in strong and gusty
winds again with cooler air moving into the region this
afternoon and tonight. High pressure will build in tonight and
dominate the region through early Sunday. The next low pressure
system along with rain will arrive Sunday afternoon and remain
over the region into the middle of next week.

Near term through tonight
Dry cold front currently moving into the upstate will move
through the forecast area this morning. As the front moves
toward the coast and offshore this afternoon high pressure along
with cooler and drier air will move into the region. This will
result in a tight pressure gradient and another day of strong
and gusty winds. With the strong and gusty winds the lake wind
advisory remains in effect through 7 pm this evening. With the
winds ushering in cooler and drier air temperatures this
afternoon will be several degrees cooler than yesterday with
highs in the mid 70s to around 80. The dry air and winds
continue to dry fuels across the area with concern for the
eastern midlands while fuels in the central and western midlands
are a bit more moist. With the concern have issued a fire danger
statement for several counties in the eastern midlands where
conditions are of greatest concern with forestry partners.

Tonight high pressure will continue building into the region and
with the cold front pushing further off the coast the pressure
gradient will begin to relax. Although the winds will subside
expect wind speeds between 5 and 10 mph overnight which will
prevent radiational cooling conditions from becoming optimal.

With the cold air advection across the region tonight low
temperatures will be in the upper 30s to low 40s.

Short term Friday through Saturday night
High pressure will dominate the region through the short term
with mostly clear skies and winds considerably lighter than the
past couple of days. With northern winds continuing temperatures
will remain in the upper 60s to low 70s for daytime highs with
overnight lows Friday night in the low to mid 40s and mid 40s to
around 50 Saturday night.

Long term Sunday through Wednesday
Synoptic situation will begin changing Sunday as low pressure
moves through the western gulf states and into the forecast area
Sunday night. As atlantic moisture overspreads the region Sunday
afternoon clouds and rain chances will return to the area. The
low pressure will slowly cross the region through Tuesday night
then eject northeastward away from the region on Wednesday. As
such have increases pops slightly with high chance to likely
pops from late Sunday through Tuesday night. With the clouds and
rain through much of the long term temperatures will be slightly
below to near normal.

Aviation 08z Thursday through Monday
Vfr. A dry cold front will come through this morning. Llws
confirmed by recent acars soundings at cae. Breezy surface
winds expected later today with gradually veering directions.

Wind and dry air will preclude any fog stratus concerns through
the TAF period.

Extended aviation outlook
Dry air should preclude restrictions Fri sat. Increasing moisture
and chance of precipitation possible by late Sunday into early
next week.

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.
