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.

639 am edt Sat may 25 2019
Convective activity on the northern side of the ridge again
today. A cold front will remain near the area Sunday through
Monday, before returning north as a warm front early next week.
Near term through tonight
As of 635 am Saturday...
bumped up temperatures slightly area wide this afternoon. Also
timed the showers in central ky for arrival in our western cwa
using the WRF and rap.
As of 240 am Saturday...
life on the northern side of the upper level closed high ridge
will continue to be on the active side through today.
First off, will be tracking a subtle mid level wave currently
producing showers over central ky this morning, and expect this
to ride the upper level flow into the CWA in the late morning
hours. NAM and rapid update models have been keying on this
feature for several hours. Early arrival should not have an
affect on inhibiting later convection during the
afternoon evening as the atmosphere should have plenty of time
to recover once it moves through and out of the cwa, not to
mention the surface based instability could increase from it.
Expect some blossoming of storms later today, and along with the
thinking from spc, stronger storms should reside over the
northern cwa. Any storms advecting into the cwa, especially
north, will be moving into an overall favorable environment for
sustainability despite weaker mid level lapse rates and a
profound lack of moisture above 650mb or so. Activity should
wave significantly with sunset.
An overnight MCS tracking nearly west to east from the mid
mississippi valley warrants pops across the west for later into
Temperatures dewpoints continue the warm and muggy trend. 70f
dewpoints likely again today.
Short term Sunday through Monday night
As of 200 am Saturday...
a frontal boundary will remain near the area for Sunday into
Monday, before returning northward as a warm front. This will
provide periods of showers and thunderstorms. With the front
providing a focusing mechanism, there is some concern that flash
flooding could become an issue.
Long term Tuesday through Friday
As of 200 am Saturday...
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. Still considerable differences|
between the models in the timing of these fronts and the intensity
of the cooler air behind them. This leads to a lower confidence
forecast for late in the week.
Aviation 12z Saturday through Wednesday
As of 635 am Saturday...
expecting more rounds of scattered showers and thunderstorms
for the region later this morning through the early evening.
Tailored the timing of the convection at each terminal with the
highest pops in the forecast, but this could change going
forward. Amds likely today as ifr and prevailing tsra are not in
the 12z forecast.
For the terminals that receive rain, and expect this to be all
of them at some point through the day, this will pave the way
for fog tonight. Trended this to ifr visibilities for after 06z
Sunday, which will likely need to be lower in some cases, but
wanted to convey the degrading conditions expected in valley
Forecast confidence and alternate scenarios through 12z Sunday...
forecast confidence: low.
Alternate scenarios: shower and thunderstorm timing could vary
from forecast. Fog development tonight could vary from forecast
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.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
