Marine Weather and Tides
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.
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.

Short term (today and tonight)
issued at 242 am cdt Thu apr 19 2018
early morning water vapor imagery together with 500mb heights and
surface obs showed the compact upper level vorticity maxima over
indiana. Surface high pressure was building in the wake of this
system across the dakotas, and this will move over minnesota and
wisconsin over the next 24 hours.
This will set the stage for clear skies and light winds and keep the
region dry. The one area of concern, if you want to call it that, is
the potential for fog overnight. Boundary layer moisture will
increase as snow melts, and the lack of mechanical mixing should
keep this layer fairly shallow and yield favorable conditions for
radiation fog. Did add patchy fog into the forecast for tonight, and
increased today's highs a bit above guidance given the full sun
expected throughout the day.
Long term (Friday through Wednesday)
issued at 242 am cdt Thu apr 19 2018
the extended forecast looks warm and fairly dry. The lone exception
is Monday night into Tuesday. There is increasing model agreement
that an upper level wave will drive a cold front across the region
with rain showers developing along it. As of now thermal profiles
look too warm for snow except perhaps north of i-94, but at most
expecting a rain snow mix with no accumulation.
The main area of interest is a deep western trough that become cut
off across the 4-corners region Friday and Saturday. This upper
level vorticity slowly slides to the southeast, and this seems
reasonable since it does appear to be caught up in the subtropical
jet. Could see some light rain showers across southern minnesota
with this wave, but the more likely solution is just mid high clouds
overspreading the region for the weekend. These clouds could hold
back temperatures on Saturday, so kept highs right at the blended
Next week looks warm. Most of the snow should be gone, and warm air
advection becomes more common place across the upper midwest for
Sunday and Monday. Aside from the warmer temperatures, this will
also bring in stronger winds to aid in mixing and heating. Continued
the trend of the previous forecast to raise high temperatures above
guidance for Sunday and Monday. Tuesday is tricky with the frontal
boundary approaching with clouds and precip, so continued with the
blend the rest of the forecast.
Aviation (for the 06z tafs through 06z Thursday night)
issued at 1016 pm cdt Wed apr 18 2018
high pressure will be in control of things this period, which
means light winds and nothing more than some thin high clouds.
Only concern for aviation purposes comes Thursday night in the
form of the potential for dense fog to form with light winds,
clear skies, and added moisture from snow melt is expected to
increase the fog threat. However, this looks to come largely after
6z Friday, so will be the main concern for the 12z tafs.

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.
