Synopsis
High pressure remains in control through Tuesday bringing dry
weather with moderating temperatures. Wet weather returns
Wednesday into Thursday as low pressure moves through our
region. Mainly dry weather follows on Friday before becoming
dreary again next weekend.

Near term through today
High pressure builds over the region today. Moisture cross
sections show a moist layer between 750 mb and 850 mb this
afternoon. This may be enough to generate a few clouds above
5000 feet, but otherwise a sunny day.

The light pressure gradient will mean light winds today, but
will also be favorable for sea breezes developing along the
coast during the late morning midday and continuing through
afternoon.

Mixing yesterday reached to nearly 750 mb, per 00z soundings.

Model cross sections show mixing to 800 mb today. Temperatures
at that level will be -5c to -6c, which is equivalent to 0c to
-1c at 850 mb. Fully mixed, this would favor MAX sfc temps in
the upper 50s and around 60. Mixing a little deeper would
support MAX temps 60-65. Cooler temperatures near the coast due
to the sea breeze.

Short term tonight through 6 pm Monday
High pressure remains overhead tonight and Monday. Expect
radiational cooling tonight, bringing another chilly night with
areas of frost, even some temps below freezing. Sunny skies on
Monday with light wind, which will again allow developing sea
breezes. Similar deep mixing to today, but with temperatures a
few degrees warmer and supporting sfc MAX temps in the low to
mid 60s away from the cooler coast.

Long term Monday night through Saturday
* highlights...

- warm up early next week
- wet and breezy midweek
- perhaps a reprieve Friday
- more showers possible Saturday
21 12z guidance remained in rather good agreement with the
overall synoptic pattern through Wednesday. Then typical timing
and amplitude differences creep into the solutions. Prefer a
consensus blend to smooth over the less predictable features for
this time range.

Expecting well defined mid level northern and southern stream
features to phase over the central appalachians about mid week.

Guidance remained consistent with that idea from previous runs.

It's how the pattern evolves after this phasing where some
questions remain, particularly with timing. In most cases,
looking like a period of wet weather sometime Wednesday, and
perhaps lingering into Thursday. Depending on timing, another
front may pass through our region sometime Friday into Saturday.

Temperature-wise, looking much closer to normal early next week.

Seabreezes likely on Monday, so cooler towards the coasts. Below
normal temperatures should return mid week, then remain near to
below normal into next weekend.

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.
