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.

1037 am edt Fri may 24 2019
Weak cold front drifts south this morning and lifts back north
tonight. Another cold front will remain near the area Saturday
night through Monday, before returning north as a warm front.
Near term through tonight
As of 1030 am Friday...
front situated across NE ky into the southern coal fields of wv
this morning, as depicted by rap low level theta E gradient,
visible satellite, and radar echoes. This will serve as the
primary focus for convection this afternoon, lingering perhaps
into this evening. After interrogating latest cams along with
sref probs, elected to increase pops a bit along the boundary
into this afternoon which will slowly be moving northward as a
warm front. MLCAPE is progged to increase to near 2000 j kg in
the vicinity of the boundary this afternoon. Coverage of
convection is not expected to be great and should be void of
organization, given marginal deep layer shear and mid level
lapse rates. Overall lack of deep moisture and a capping
inversion should also be a limiting factor, helping to keep
much of the action near the front where better moisture will
reside. Aforementioned model signals do try to hone in on the
coal fields up to the parts of the kanawha valley as perhaps
the locations to see slightly better coverage.
Spc has highlighted parts of SE oh and southern half of WV in a
marginal risk for severe. This seems warranted with rap dcape
values and soundings supportive of a damaging wind threat. While
the threat for large hail is not zero, a repeat of yesterday is
not expected with poor lapse rates and less in the way of shear
Activity should diminish greatly with sunset as boundary layer
cooling allows the mid level cap to become established once
As of 615 am Friday...
made some adjustments to the forecast this morning in the pops,
but all changes were relatively minor. Expansion further north
for the slights across the west over the next 12 hours.
As of 210 am Friday...
tough to pick out the front this early Friday morning, but is
probably near the ohio river based on current wind directions in
southeast ohio and west central west virginia. This feature
should drift southward and settle over the southern part of the
state today, which is where the chances for showers storms
resides today this evening. The rapid update guidance numbers
brings in a cooler day today with front sitting south, but there
remain a couple outliers trying to push upper 80s for portions
of the lowlands. Some minor bust potential here dependent on the
the front location.
On the synoptic scale, the southeastern us upper closed low
dominates the pattern, but there is enough flow aloft pushing
the aforementioned front through. Front will come back northeast
as a warm front tonight, and this warrants low end pops
returning late for showers. Sufficient moisture layer depth is
an issue, however.
Short term Saturday through Monday
As of 225 am Friday...
a high pressure system on Saturday will give way to a cold front
by Saturday night. This front will flirt with the area through|
Monday, before returning northward as a warm front. This will
provide periods of showers and thunderstorms.
Long term Monday night through Thursday
As of 225 am Friday...
an upper level ridge will build over the region for Tuesday and
Wednesday, allowing for 20 c temperatures at 850 mb. This could
allow temperatures to reach into the lower 90s for much of the
A cold front or series of cold fronts will then effect the area
for late in the work week. There are considerable differences
between the models in the intensity of the cooler air behind
these fronts, leading to some uncertainty at this time.
Aviation 14z Friday through Tuesday
As of 615 am Friday...
some MVFR stratus clouds developed overnight and will expect a
gradual lifting of this layer over the next few hours. Same
holds true where fog tried to creep into crw but was likely
inhibited by the aforementioned stratus. There are
convection storm chances today, but they are low and only expect
isolated activity, and should only be a potential issue for the
hts crw bkw line. Mountain valley fog expected tonight, ckb to
crw and east into the mountain valleys with a clearing sky and
Forecast confidence and alternate scenarios through 12z Saturday...
forecast confidence: high.
Alternate scenarios: ceilings toVFR timing may vary this
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.

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.
