Synopsis
A cold front will move across the chesapeake bay this morning.

High pressure will gradually build across the region during the
second half of the week.

Near term today
Personal note - after 33 years in government and 23 years at lwx
i'm calling it a day. It's been a great honor to serve my
country. Thank you.

And a very wild end to the ride it's been on this overnight
shift. I suppose there are records on it, but I doubt there have
been too many oct 24s that have featured 70 dewpoints at 2 am.

This is more like what youd see in late july. But over the past
two hours some of this moisture has been wrung out as the cold
front is now crossing the i-95 corridor.

The band of precipitation may be slow to clear the bay and will
hold onto at least pops until late afternoon.

This will be the final day of well above average temperatures
with highs in the 70s.

Short term tonight through Wednesday night
Upper trough axis crosses the area Wed (gfs) or Wed night
(ecmwf) with temps staying in the 60s during the day and 40s at
night. Any precip would be confined to the upslope areas.

Long term Thursday through Monday
Troughing will remain entrenched over the eastern CONUS through the
period as ridging persists out west and over the north atlantic.

This will lead to near normal temperatures late this week into the
weekend. A spoke of energy will rotate around an upper low stationed
just southwest of james bay likely bringing another period of
unsettled weather at some point next weekend, but timing placement
details remain fuzzy this far out.

Aviation 10z Tuesday through Saturday
Ifr MVFR ceilings at the major sites early this morning will see
improvement as the morning progresses. ThenVFR tonight.

MainlyVFR expected late in the week with light flow.

Marine
We are seeing gale level gusts on the bay. This will be in
effect for the widest portion of the md section of the bay until
3 pm, further north until 8 am. Then SCA everywhere for the
remainder of the day.

Light flow with high pressure over the waters thu-fri.

Tides coastal flooding
Waters are running above normal on southerly flow. A warning has
been issued for anne arundel as water levels continue to climb.

Advisories are in effect along the western shore of the bay
through midday.

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.
