Marine Weather and Tides
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.
10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name.

521 am edt Tue mar 26 2019
High pressure provides dry and cool weather today, with a
warming trend to follow. The next chance of light rain will
arrive on Thursday with an approaching front.
Near term until 6 pm this evening
Only minimal changes to sky cover and dewpoint were needed
at 520 am, as the forecast remains on track.
A much drier air mass continues to sink southward across the
cwa. Clouds are generally confined to areas south of the mason-
dixon line and east of mgw, and expect these to dissipate over
the next few hours.
The daytime hours will be dominated by abundant sunshine as high
pressure builds in from the northwest. Despite the near total
lack of clouds and the dry air mass, continued northerly flow
and slow 850 mb cold advection will help to keep afternoon highs
5 to 10 degrees below the seasonal norms.
Short term 6 pm this evening through Wednesday night
The high center crosses tonight, with good radiational cooling
conditions keeping low temperatures around 10 degrees below
normal, in the lower to mid 20s for most areas. Wednesday will
be another dry day, although a weak mid-level wave will pass by.
Levels from 500 mb and below will be much too dry for clouds,
but a few high clouds may be produced by the shortwave. Low
level flow shifts to the south by the afternoon, and
temperatures will be able to recover to near, or even just
A cold front will begin to sag across the great lakes Wednesday
night as ridging flattens over our area and mid-level flow
trends towards zonal. The dry air mass in place should help to
quash any showers that try to approach during the night,
although clouds will be on the increase toward sunrise. A
slowly tightening surface pressure gradient will keep the low
levels stirred through the night, and keep many areas above the|
Long term Thursday through Monday
The front eventually flops into our region by later Thursday or
Thursday night, with chances for light rain showers initially.
As the front becomes parallel to the mean flow, it will likely
become nearly stationary in or near the cwa. This will keep
light rain chances going through Friday night, although
precipitation will be fairly spotty overall.
Better chances for steady rain arrive on Saturday, as a
shortwave from the rockies teams up with a weak disturbance over
the central plains and rides along the stubborn front. Pops were
maximized with likely values for Saturday afternoon and night.
Showers will linger through Sunday as the trailing mid-level
wave passes through, with some snow showers possibly mixing in
at the tail end of the system. High pressure returns dry weather
Temperatures will generally run above seasonal norms through
Saturday, but cooler temperatures will return behind the potent
storm system for Sunday and Monday.
Aviation 10z Tuesday through Saturday
Vfr conditions are expected through the period with light
northerly winds and clear skies.
Vfr expected through midweek. Restrictions possibilities return
late week with a quasi-stationary front.

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.
