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.

Updated for 18z TAF discussion below
Short term (today and tonight)
issued at 439 am cdt Thu oct 18 2018
clear skies have allowed for efficient radiative cooling with
temperatures cooling into the upper 20s to lower 30s this morning.
Despite the cool start, today will be the first day to have above
normal high temperatures since october 3rd.
Soundings indicate a stout warm nose this morning, especially over
western mn where just about 900 feet off the surface, temperatures
are in the 50s. With continued warm air advection through the late
morning, 925 mb will range from 16 c (61 f) in far western mn to to
9c (48 f) in central wi this afternoon. Sunny skies should allow for
strong mixing, but there is medium confidence on exactly how high
the boundary layer will mix to. Most model guidance indicates mixing
to near 925 mb over western mn and more shallow mixing to about 950-
935 mb over central mn and wi. The forecast MAX temperatures account
for the more shallow mixing but are still above guidance. This was
done by blending in the mix down 925 mb temperatures with the
previous MAX temperature forecast. If the CWA does indeed mix to 925
mb, then widespread 70s would be likely over western and central mn.
It will be a another breezy day with increased pressure gradient
ahead of a shortwave trough. Widespread wind gusts near 20-25 mph
are likely during the late morning and afternoon. The wind gusts
will subside with the decoupling boundary layer before increasing
again during the mid morning on Friday with a strengthening low
level jet. Moisture advection will allow for an increase in cloud
cover and chance for light rain as the shortwave trough approaches
from the dakotas Friday morning.
Long term (Friday through Wednesday)
issued at 439 am cdt Thu oct 18 2018
a cold front will be passing through during the day Friday. Gusty
southwest flow in advance of the front will become gusty northwest
behind it with gusts of 30 to 35 mph possible. It will still be a
mild day, but not as warm as today. Earlier CAA aloft should
limit warming potential even as the surface front lags some. Still
expecting highs in the low to maybe some mid 60s across the south
A very potent vort will descend southward from central canada to
the great lakes upper midwest late Friday night and Saturday
morning. There will be a small window with this feature to produce
snow showers Saturday morning before drier air aloft cuts off any|
ice crystal production. It may only be a 2 to 3 hour window, but
the snow showers could be impressive given the forcing and
steepening lapse rates. Could see up to an inch over western wi.
The steepening low level lapse rates will also lead to enhanced
wind gusts with the top of the channel nearly 40 kts.
Ridging will build in rapidly Saturday afternoon, which should
help to scatter out the clouds and ease the wind by evening.
The rest of the long term period will be quiet with periodic cold
fronts and surface ridges. Temperatures will average closer to
Aviation (for the 18z tafs through 18z Friday afternoon)
issued at 1245 pm cdt Thu oct 18 2018
gusty SW winds ahead of next system expected into the evening.
Band of rain associated with next upper trough should spread mid
clouds across the southeast portion of the area mainly 06z-12z.
Will see some llws ws020 22045kt develop mainly 02z-11z. May see
ceilings drop to MVFR in the krnh-keau area late and continue into
Friday morning. Winds picking up ahead of first cold front which
should drop through much of mn area through 18z Friday. Gusty nw
winds 25-30 kts possible behind this front.
Kmsp... Southwest winds are expected to gust around 20 kts this
afternoon. Llws ws020 23045kt will be a concern after sunset.
Period of -ra possible mainly 07z-10z but expect ceilings to
remainVFR. Winds will becoming NW through 17z and gusty to
25-30kts possible in the afternoon.
Outlook for kmsp
fri night...VFR with MVFR and -ra possible. Wind SW becoming nw
Sat...VFR with MVFR -shsn possible early. Wind NW 10-15g25-30kts

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.
