Marine Weather and Tides
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.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

A chance for showers will continue today and into Wednesday, as
a trough of low pressure remains centered over the great lakes.
High pressure will move into the area late in the week, with a
slight increase in temperatures. Another cold front will move
into the area late on Friday.
Near term until 6 pm this evening
Highly amplified mid upper level flow pattern with large deep
trof over the eastern u.S. And a strong ridge over the west.
Initial S W is rotating into lower mi as next S W visible on wv
imagery is pivoting thru indiana. A surface reflected trof and
axis of rain showers pushing into western ohio was a result of
this S w. Expect these showers to push east across iln S area
through the early morning hours. As the favorable lift exists
the area expect a general lull in pcpn activity later this
Additional showers are expected to develop this afternoon as
next S W currently digging across ia comes into play. Have gone
categorical for the early morning activity and then high chance
this afternoon with the best coverage across the north. Clouds,
pcpn and CAA will keep temperatures down today. Expect highs
from the lower 50s northwest to the upper 50s southeast.
Short term 6 pm this evening through 6 pm Wednesday
Large mid level trough will keep conditions cloudy and cool
through mid week. Have diminished pops this evening, keeping
only chc slight chc pops across the northern counties thru the
night. Cool night with lows from the upper 30s to near 40.
Model solutions show a digging S W dropping into the mean trof
position over the ohio valley Wednesday. This will provide a
continued threat of a shower. H8 thermal trof settles into the
region with temps of -1 to -3 degrees c by evening. Expect
temperatures to be close to 15 degrees below normal with highs
only reaching the upper 40s in many locations.
Long term Wednesday night through Monday
Upper trough will be departing east Wednesday night, with
isolated showers ending before midnight. Frost may form toward|
daybreak Thursday when temperatures fall to near freezing. High
pressure centered to the south will provide dry weather Thursday
into Friday. Impressive moisture advection along a cold front
developing ahead of a high amplitude upper trough will bring the
likelihood for showers late Friday through Saturday, with
showers lingering Sunday mainly in eastern locations. Expect
drier conditions Monday when high pressure is forecast to build
to the south.
Look for near normal temperatures Thursday and Friday, with highs
around 60. Readings will then plunge below normal in a regime of
cold advection Saturday through Monday, yielding highs around 50.
Aviation 12z Tuesday through Saturday
Several surface troughs will rotate through the area as a deep
upper level low migrates through the great lakes. This will
result in several bands of rain showers that will pivot
across the area. CIGS are variable with widespread MVFR cigs
and a period of ifr CIGS in the wake of this early morning sfc
These MVFR are generally expected to lift back toVFR by late
morning early afternoon before coming back down this evening.
Vsbys will also be variable withVFR conditions outside of rain
showers but dropping to MVFR in some of the heavier rain
showers. Pcpn coverage will generally decrease though the
morning into the afternoon hours.
Breezy southwest to west winds will persist today with some
gusts to up 25 knots.
Outlook... MVFR ceilings and visibilities are possible at times

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.
