Discussion
Current sfc analysis shows the cold front over our coastal waters
with high pressure centered over the upper ms valley now ridging
over the forecast area. Latest obs reflect this with temps
generally in the 50s and dewpoints in the mid 40s-lower 50s. Water
vapor imagery shows troffing in place across the ERN cntl conus
with a shortwave noted dropping sewd out of the plains into the
mid-south this morning... Associated nwrly flow aloft is helping
usher in drier air per 00z regional soundings and corroborated by
clear skies on satellite imagery.

A fairly benign weather pattern looks in place for at least the
first half of the forecast period as sfc high pressure nrly flow
aloft maintain dry conditions through the column. Temperatures look
to run below normal through mid-week, especially tonight when mins
are forecast to be 5-10 degrees below climo. As the high moves
east of the area Wednesday night into Thursday, temps begin to
moderate while low-level moisture begins to creep upward on the
heels of return flow.

After a brief shot of precip Friday with the passage of a weak
disturbance aloft, rain chances ratchet up for the weekend as the
next pacific storm system crosses the rockies and helps push an
associated sfc front ewd through the area on Saturday. Long range
models are a little more gung ho on lingering overrunning precip
for Saturday night and Sunday than this time yesterday, followed
by another potential round of showers associated with the passage
of the mid upper-level trof axis for Monday. Guidance indicates
another shot of cooler temps are on tap for late in the weekend
and early next week.

Marine
Introduced caution headlines on the outer waters for this morning
as a tightening gradient and CAA induce a brief round of elevated
nrly flow. After winds relax for the afternoon, signs of another
round of moderate nrly flow later tonight as the upstream
shortwave helps push a reinforcing cool front through the area and
into the coastal waters.

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.
