Synopsis
Near record temperatures will continue through the end of the
week. High pressure centered off the coast will bring warm and
moist air into region through Saturday. A cold front will cross
the area Sunday into Monday bringing a high chance of showers.

Temperatures will remain above normal next week.

Near term through tonight
Temperatures are warming through the mid 70s to around 80 early
this afternoon after low clouds this morning have transitioned
into diurnal stratocumulus. Visible imagery showing better
clearing with deeper mixing across the piedmont and central
midlands while clouds are a bit thicker over the eastern
midlands but should also improve through the afternoon. Still
expecting near record high temperatures if clouds continue to
dissipate with highs in the lower 80s.

Another mild night expected with little change in the airmass
and upper ridge in place as well as surface high offshore
continuing to circulate warm and moist air into the region.

Stratus fog expected to redevelop overnight with overnight lows
in the 60s with potential to break more record highest minimum
temps. Confidence is a little lower in temps tonight though
given some uncertainty in the overall coverage of low clouds and
areas that do not get the clouds may radiate a bit better
resulting in cooler overnight lows and potentially more fog
potential.

Short term Friday through Saturday night
An upper ridge will remain over the region on Friday with
surface high pressure centered off the southeast coast. This
will promote another unseasonably warm day across the area.

High temperatures are forecast in the lower 80s. The upper ridge
will weaken some on Saturday and high pressure will begin to
retreat eastward a bit. Moisture will deepen some across the
area on Saturday and into Saturday night promoting a slight
chance of rain. Above normal temperatures expected once again on
Saturday with highs in the lower 80s. Overnight temperatures
will also be mild both Friday and Saturday nights, in the lower
60s. Patchy fog is expected to develop early Saturday morning,
although the low level jet is forecast to be stronger than
Friday morning.

Long term Sunday through Thursday
Low pressure over the upper great lakes region will shift into
canada on Sunday bringing a cold front into the forecast area.

Southwesterly flow will bring deep moisture into the area with
increasing chances of rain through the day Sunday and into
Monday. The best chance for rain appears to be Sunday night
through Monday evening so have continued with likely pops. The
front is expected to be off the coast by late Monday night with
high pressure building back into the area. The ECMWF is a
little slower moving the front through the area than the gfs.

Tuesday is expected to be dry with high pressure over the area.

High pressure will move off the coast on Wednesday with
moisture and the chance of rain returning to the forecast area.

Unsettled conditions will continue through the end of the work
week. Temperatures through the period will remain above normal.

Aviation 19z Thursday through Tuesday
High confidence inVFR conditions through aftn eve then expect
fog stratus to redevelop late tonight.

Southerly flow this afternoon 5 to 10 knots will diminish to
light and variable or calm after sunset with no low level jet
forecast overnight. The lack of winds aloft and expected
clearing of skies this evening after diurnal clouds dissipate
should provide good radiational cooling conditions which may
promote fog. Confidence is a bit lower in the coverage of
fog stratus and have confined possible lifr conditions to the
more favored ogb ags terminals 09z-13z. Otherwise bring in
MVFR ifr CIGS after 07z-08z. Improvement expected by 14z-15z
with a return toVFR by 17z all terminals.

Extended aviation outlook... Little change through Sunday morning
with late night morning cig vsby restrictions. Chance of showers and
associated restrictions Sunday afternoon 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.
