Synopsis
High pressure will be over the region through the end of the week
allowing for above normal temperatures. The ridge of high pressure
will strengthen further over the weekend into early next week,
leading to near-record high temperatures over the memorial day
holiday weekend.

Near term through tonight
Current satellite imagery shows cumulus developing over the
forecast area with WSR-88D returns showing a few lingering
showers in the upstate into nc as a weak short wave rotates
through the ridge. Through the day and tonight the upper ridge
will continue building with temperatures held somewhat in check
by the developing cumulus. Aloft plenty of dry air remains and
with weak mid level lapse rates the potential for convection is
low. With the flow in the low and mid levels turning more
westerly through the afternoon and some downsloping expect a bit
more drying and have retained the dry forecast through the
afternoon and overnight hours. Afternoon high temperatures will
range from the upper 80s north to the low 90s in the csra.

Overnight lows will be around 70.

Short term Friday through Friday night
High pressure continues to build over the region. Mostly dry
conditions, along with above normal temperatures, will persist.

Afternoon highs will warm to the mid and upper 90s as winds
become downslope, and 850 mb temperatures continue to warm.

Nighttime lows will be in the upper 60s and lower 70s.

Long term Saturday through Wednesday
Little change in the long term thinking. The main concern
will be the very hot temperatures, with near record or record
highs each afternoon through the middle of next week.

With both surface and strong upper ridging building into the region,
temperatures are expected to climb into the mid upper 90s with
possibly some the low 100s in some locations each afternoon.

Due to the expected strength of the ridge, along with a mid-
level capping inversion each afternoon, shower and thunderstorm
activity will be suppressed. Because of the dry conditions,
light winds and lack of humidity, heat indices (apparent
temperatures) may actually be a few degrees cooler than the
actual temperatures.

Aviation 15z Thursday through Monday
Vfr conditions through much of the period with early morning
MVFR ifr possible.

Cumulus have begun developing and will increase in height over
the next couple of hours ending any remaining restrictions at
the terminals. Through the afternoon and evening hours
additional cumulus will develop however convection will be very
limited due to dry air aloft. Winds will remain light and
variable through 17z... Then become southerly around 6 knots
through this evening... Returning to light and variable with
sunset. Main concern will be potential for fog and stratus
forming during the early morning hours. Although confidence in
increasing in restrictions have kept mention out of tafs attm
and will likely include in next issuance.

Extended aviation outlook... Late night early morning
fog stratus possible along with isolated afternoon evening
thunderstorms through Monday.

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.
