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 tonight through Tuesday
issued at 256 pm cdt Mon mar 19 2018
the main forecast concern was focused on the light snow to move into
western iowa Tuesday. Models continue to be in great agreement with
timing and location of the light snow Tuesday and thus no
significant changes to the ongoing forecast. Surface low currently
tracking across missouri remains well south of the forecast area
tonight and will mainly bring some cloud cover across the south
this evening. A very weak 500mb shortwave enters western iowa b t
06-12z Tuesday and transitions across the state throughout the
day. Saturation begins during the same time at crl to fod to est
and have high pops going past 09z through 18z Tuesday. Forcing is
within the dendritic layer, albeit weak, but should be strong
enough to overcome the shallow dry layer near the surface tomorrow
morning. As the shortwave moves east, the weak forcing diminishes
and have low confidence with much snow accumulation east of
interstate 35. Especially with the surface temperatures warming
into the upper 30s to lower 40s toward the afternoon. There is
another vort MAX that stretches across western iowa by late
Tuesday afternoon and may regenerate some snow showers over the
west to northwest during this time. Thus, kept light snow
accumulations going in the northwest b t 18-00z tomorrow and may
need to extend pops past 00z Wednesday over the far northwest.
Particularly if there is some lingering deeper moisture and ice
introduction into the column.
Long term Tuesday night through Monday

another quick moving shortwave looks to bring rain and or snow to
the central and southwest portions of the forecast area Thursday.
Forecast soundings portray a fairly deep dry layer below 800mb to|
the surface Thursday morning. GFS is certainly stronger with the
forcing and as a result, higher with the QPF amounts. Regardless,
surface temperatures look to be warm enough to melt any snow prior
to reaching the surface and have low confidence with much
Friday into Saturday, there remains some uncertainty wrt the surface
low track across the region. Models have at least come into decent
agreement with timing of the surface low. The GFS is slightly faster
and further south than the ECMWF Saturday morning. Still, models
place the forecast area within the easterly flow and rain much of
the day. Confident to at least lower maximum temperatures a few
degrees on Saturday and leaning to the potential for slightly more
snow over central to northern iowa. Models diverge in solutions
late in the weekend into early next week and low confidence with
any precipitation location and type Saturday night into Monday.
Aviation for the 00z tafs through 00z Tuesday evening
issued at 638 pm cdt Mon mar 19 2018
main challenge will be extent of MVFR CIGS across the area by 12z
along with coverage of light precipitation. Inverted trough
should weaken as it crosses area Tuesday... Though may still pull
lower MVFR CIGS as far east as kmcw... Remaining west of kalo kotm.
Vsby may drop to 2sm-5sm across north northwest as snow reaches
area aft 11z west with coverage remaining less and better vsby
generally east of i35. Will monitor trends for next update at 06z.

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.
