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.

853 pm edt Tue may 21 2019
Rain chances return with a late Wednesday warm front, and again with
a Thursday cold front.
Near term through Wednesday
Isolated, very light showers drizzle continue to move into the
region in northwest flow. Given substantial dry air from 700 to
850mb as seen in the 00z sounding, most radar returns are likely not
making it to the ground. However, several observations have included
light rain, and light rain was obsevered at pbz, so have continued
to carry drizzle across affected areas for the next couple of hours.
Any remaining shower activity should end this evening. Previous
the bulk of the next 24 hours will be dry as a result of high
pressure centered over lake superior that extends southeast across
the rest of the great lakes. This quiet stretch of weather will be
interrupted by the potent storm system that is currently producing
severe weather in the central united states. The warm front from this
system will approach the region Wednesday afternoon and bring a
chance of thunderstorms. Respectable low level lapse rates and shear
will pose a threat for severe storms, at least across eastern ohio if
not farther east. The ensembles are more aggressive than the
deterministic models with the coverage of thunderstorms, so
increased pops across the area, but did not have enough confidence to
go with likely pops at this time. After cooler temperatures today,
highs should range from the lower 70s to the lower 80s on Wednesday.
Short term Wednesday night through Friday
The warm front with the low pressure system will move through the
region Wednesday evening, with the associated cold front arriving
late Thursday. Both wind shear and instability values will be higher
on Thursday, and all locations will have the threat for severe
weather, particularly during the late afternoon and early evening
hours. However, the threat does not appear to be nearly as strong as
the severe weather that has been ongoing in the plains. Still did not|
have enough confidence to add likely pops to the forecast, and the
forecast thinking is that thunderstorm coverage will remain
scattered. The threat of rain will continue Thursday evening, but
conditions should dry out on Friday with the front pushing through to
the south. Temperatures will be above normal, with highs ranging from
the mid 70s to the mid 80s.
Long term Friday night through Tuesday
While there will be some ripples occasionally in the upper level
flow, the flow will generally be zonal through the time period. This
will allow multiple shortwaves to move through and bring a repeated
chance for showers. The most defined feature through the extended
forecast is a cold front that will move through Saturday, and modest
amounts of wind shear and instability will allow for yet another
chance of severe weather on Saturday. Confidence was not yet high
enough to include in the hwo at this time. Temperatures will remain
above normal through the period.
Aviation 00z Wednesday through Sunday
Vfr expected through the TAF period. Sfc high pressure will be
displaced east as a sfc warm front moves into the region Wed under
an upper level ridge. Wind will veer with the approach and passage of
the front, changing from E to sse with speeds around 10kts.
Enough daytime heating plus increased lift from a weak disturbance
rounding the upper level ridge will generate isolated to scattered
thunderstorms across eastern oh to kpit Wed evening.
Periodic restrictions are possible through the weekend as
disturbances round the upper level ridge.

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.
