Marine Weather and Tides
3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.

Short term (tonight through Thursday night)...
two distinct upper lows combined with a brief shortwave ridge in
between highlight the upper synoptic pattern this afternoon, while
at the surface low pressure pulls away into the mid atlantic as high
pressure slides east into the midsouth. Modest moist nwly flow
continues to promote light showers across the region this afternoon,
however with a gradual decreasing trend in coverage fcst. Thus,
pops initialize in the high chance to low likely range across the
central valley and high terrain along the nc line where upsloping is
favored. Pops will then lower to slight chance levels overnight as
the first system pulls away.
The next upper low will slide east overnight into the midsouth
region, pushing further into middle tn by daybreak Thursday.
Conditions are expected to remain dry yet cloudy across east tn and
southwest va nc through sunrise, before a weak warm frontal axis and
associated WAA regime spread showers east of the plateau into the
great valley by mid late morning. With that, pops will ramp up to
likely levels regionwide, with low end categorical pops favored
south of i40 were best moisture and lift will overlap given expected
track of the sfc upper lows. Speaking of the upper low, fcst
profiles would also suggest modest lapse rates given cooling aloft,
therefore did include slight chances for thunderstorms south of i40
as well. Pops will remain elevated through the day before the
system pulls away to the east through the evening overnight. By
period's end Friday morning, only low end pops are highlighted along
the high terrain amidst developing nwly flow. Temperatures on
Thursday will once again be 8-10 degrees below normal for highs,
while lows hover near normal.|
Long term (Friday through Wednesday)...
during the day on Friday some lingering precipitation and a second
wave of light rain may occur over the forecast area. If this does
occur rainfall would be light, and most places should remain dry
with cloudy skies slowly turning clearer.
After that, mostly sunny and dry weather will be the main pattern
over the weekend and through the first half of next week. Ridging
builds in from the west, but winds out of the north will help keep
temperatures at or just below normal through the weekend. As the
ridge continues to shift off to the east, winds will eventually turn
more southerly and temperatures and dew points will both increase in
response. Tuesday and Wednesday look to have temperatures above
normal with some locations expected to flirt with 80 degrees for a
high temperature. A trough is then expected to move across the
eastern half of the united states late next week and will likely
bring widespread precipitation to the area just beyond this 7 day

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
