Synopsis
High pressure will move north of the region today and tonight
with a weak disturbance developing along the coast late Sunday
and Sunday night. The disturbance will move away from the region
on Monday with the next weak cold front moving through Tuesday.

High pressure will dominate during the middle of the week with
unsettled weather returning late next week.

Near term through tonight
High pressure along with dry conditions will dominate the region
today and tonight as the high moves from eastern tn through the
mid atlantic states. Clear skies and light winds will allow
temperatures this afternoon to climb into the low to mid 60s.

Excellent radiational cooling conditions tonight will allow
temperatures to fall into the upper 30s to low 40s for most
locations, but with the slightly warmer overnight lows a frost
advisory will not be needed.

Short term Sunday through Monday night
High pressure will move northeast of the region on Sunday with a
weak disturbance developing along the sc coast late in the day
and Sunday night. Models have strengthened this feature
slightly over the past couple of runs however moisture remains
contained along the coastal plain. Have increased pops slightly
over the far eastern midlands due to uncertainty in models
however still remain below slight chance through Sunday night.

The disturbance will move northeastward on Monday and Monday
night as the next cold front moves through the tn valley and
into the upstate late Monday night. Although there will be
slightly increased clouds on Monday and Monday night do not
expect any rain. Temperatures will be in the low to mid 60s for
highs Sunday afternoon and mid to upper 60s Monday. Overnight
lows will be in the low to mid 40s.

Long term Tuesday through Friday
Cold front will move through the region Tuesday and with limited
moisture and weak dynamics do not expect any precip with fropa.

High pressure along with slightly cooler air behind the front
and dry air will occupy the region for Wednesday through
Thursday with some uncertainty late in the period. Remains of
the frontal boundary will be south of the area with strong high
pressure dominating the great lakes and much of the eastern
seaboard. GFS moves the high eastward faster than the ECMWF and
returns moisture to the area late Friday while the ECMWF is
slower to move these features. Have introduced slight chance
pops for Friday and Friday night as models come into better
agreement although some uncertainty and run to run changes
continue. Temperatures through the long term will be near to
slightly below normal.

Aviation 15z Saturday through Wednesday
High pressure across the area and a dry air mass will provide
for mostly clear skies andVFR conditions through the day and
into tonight with light and variable winds mainly out of the
east. Models indicate onshore flow tonight may result in a
scattered to broken strato- cumulus deck toward the end of taf
period... After 09z. At this time it appears ceilings will remain
vfr.

Extended aviation outlook... No significant impacts to aviation
expected through Wednesday.

Hydrology
Minor to moderate flooding on the congaree river, enoree river,
great pee dee river and wateree river will continue through the
weekend and into next week. Please see river flood products or
the AHPS website at
https: water.Weather.Gov ahps2 index.Php?wfo=cae for
information on river flooding.

Cae watches warnings advisories

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.
