Update...
low-level moisture is gradually increasing across the area this evening
as evident on the evening radiosonde observation. A strong subsidence inversion remains
present around 850 mb however. Lows tonight will generally be 5 to
10 degrees warmer than what they were yesterday as winds have taken
a more easterly component as high pressure gradually moves off the
middle-Atlantic coast. Made a few minor adjustments to account for current
trends but otherwise no major changes made the forecast this evening.

&&

Aviation...
VFR conditions next 24 hours with scattered high cloudiness across the
region. Fog is not expected to develop tonight.

&&

Marine...
an area of low pressure moving across the middle Mississippi Valley as
high pressure slides off the eastern Seaboard tonight will maintain
a tight gradient over the coastal waters...with Small Craft Advisory
conditions over the outer waters and brief exercise caution conditions
over some of the near shore waters early in the evening. The gradient
weakens Sunday but then tightens again Sunday night and Monday as
a cold front sweeps across the Gulf waters. Surface high pressure
builds in across the Southern Plains and tracks along the Gulf Coast
during middle week...with generally benign winds and seas for the waters.
