ideal radiational cooling conditions with clear, cool, and dry
conditions are expected. Lows tonight will generally be in the
mid upper 30s for rural inland locations, with low mid 40s for
coastal SE va NE nc. Frost is possible for rural outlying

Aviation 08z Tuesday through Saturday
High pressure is building into the region early this morning.

The sky is clear aside from a narrow bay streamer in vicinity of
orf. A N wind is generally 5-10kt, but remains 10-15kt with
gusts of 20-25kt for orf. The wind at orf will gradually
diminish through 12z and hence the streamer should dissipate. A
nne wind should range from 6-12kt today under a sunny sky. High
pressure builds over the region tonight with the wind becoming
calm to very light under a clear sky. High pressure remains over
the region Wednesday through Saturday with the sky remaining
mostly clear with a light wind.

Marine
The latest surface analysis shows a cold front pushing well offshore
with broad high pressure building into the region. Small craft
advisory conditions are expected to continue through this morning
due to cold air advection behind the front. Wind gusts up to 30
knots will remain possible over the bay and ocean through early this
morning. Went ahead and cancelled the SCA for all of the rivers
besides the lower james as wind gusts have mainly diminished below
20 knots in these locations. Seas over the ocean will be up to 6 to
8 feet with the highest seas over the southern coastal waters. Waves
over the bay will be up to 3 to 5 feet. Seas and waves are expected
to slowly diminish early this morning and through the day today.

High pressure will allow for improving marine conditions by tonight
with just some lingering 5 to 6 feet seas over the far southern
coastal waters. The high will allow for an extended period of sub-
sca conditions through the end of the week.

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.
