Marine Weather and Tides
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 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.

Frontal boundary in vicinity into the weekend with showers and
storms. Cold front Sunday night.
Near term through tonight
As of 320 am Thursday...
as of 07z, the frontal boundary was draped across central parts
of the cwa, generally in the vicinity of the route 33 50
corridor. A few shra continue to dot the area at this early hour
as low stratus and fog take hold north of the boundary.
For today... An upper level system will approach the area from
the southwest, as the pesky front begrudgingly tries to return
north. This scenario will provide for two focusing mechanisms
for shra tsra today, with chances ramping up into categorical
from south to north today. Instability looks a bit less today
than previous days. This is especially true across the far
northern counties which look to stay north of the front until
early this evening. Pwats around 2 inches with moisture
advection from the upper level system, along with continued
warm cloud processes, will mean another day of downpours and a
flash flood threat. The most vulnerable areas are across
southeast oh and northern WV where FFG is considerably lower
than areas farther south. After mulling things over, i've
elected to hoist a flash flood watch across those locales. The
greatest threat within the watch for this afternoon looks to be
in the route 50 corridor, essentially where the front will be
located during maximum heating. This shifts into our far
northern counties this evening. The watch spans into the short
term to account for additional rains Friday. Temps may make a
run on the other side of 80 degrees before convection takes
As mentioned the main focus remains across far northern
counties and southeast ohio tonight, though I cannot rule out
stray showers or storms anywhere overnight.
Short term Friday through Sunday night
As of 250 am Thursday...
a low pressure system will move into
the great lakes region Friday into Saturday. This will keep
plenty of moisture over the area allowing for showers and
thunderstorms. Meso models are showing some pretty decent
rainfall amounts on Friday afternoon and evening, especially
over northern portions of the region. Will go with a flash flood
watch for this region.
Deeper moisture pulls out by Saturday, so while showers and
thunderstorms are still expected Saturday and Sunday, the flash
flood threat lessens.
A cold front is then expected to push through Sunday night.
Long term Monday through Wednesday
As of 250 am Thursday...
a high pressure system will build into the region on Monday,
remaining through mid week. While some residual moisture behind
the front could allow for some showers or thunderstorms in the
southern counties on Monday, expect dry weather for Tuesday into
Aviation 07z Thursday through Monday |
As of 200 am Thursday...
isolate shra threat continues across the area through the
predawn hours, courtesy of a lingering frontal boundary. North
of this boundary, ares of ifr or worse stratus and or fog will
develop, most likely affecting northern terminals. This low
stratus will be slow to dissipate Thursday, taking until perhaps
late morning to lift into a bkn MVFR CU field.
An upper level system will approach from the southwest today
with rounds of showers and storms moving through. Coverage
should be greater than yesterday with high confidence on all
terminals being affected at some point this afternoon evening.
Brief ifr or worse vsby in the strongest convection which is
being handled with 2 hour tempo groups centered around the time
of highest confidence for each terminal.
Evening showers storms will gradually wane across northern sites
this evening, with areas of low stratus developing along and
northwest of the ohio river.
Forecast confidence and alternate scenarios through 06z Friday...
forecast confidence: medium.
Alternate scenarios: timing and density of low stratus and fog
tonight may vary at northern sites. Timing of convection today
may vary an hour or two at each site.
Experimental table of flight category objectively shows consistency
of WFO forecast to available model information:
h = high: TAF consistent with all models or all but one model.
M = medium: TAF has varying level of consistency with models.
L = low: TAF inconsistent with all models or all but one model.

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.
