Marine Weather and Tides
Isle, MN

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 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.

Short term (today and tonight)
issued at 300 am cdt Fri jun 22 2018
not much change to the forecast. Today will partly sunny with highs
near 80. Winds will be light as well with an easterly component.

Tonight winds will become a bit more southerly with a few areas of
patchy fog possible. Lows will be around 60s.

Early morning water vapor imagery together with rap13 500mb heights
and winds showed the wound up cyclone over the illinois river
valley. The high level cloud shield extended across the upper
midwest, and these clouds will stick with us most of the day today
and bring filtered sunshine across the region. A baggy surface ridge
extending from quebec eastward across lake superior and minnesota,
and this will bring us light winds today and tonight.

Long term (Saturday through Thursday)
issued at 325 am cdt Fri jun 22 2018
no major changes to the extended period as the weak flow aloft
remains in place until the middle of next week.

Two weather systems will move across the upper midwest in this
weak flow aloft through Wednesday of next week. The first system
has remained very weak and disorganized in terms of surface
features. However, summer time instability, although not strong,
will be capable of generating a few storms during afternoon
heating. The best location and generally higher chances of
precipitation, will occur in west central, southwest and south
central minnesota Saturday afternoon, and evening. Further to the
northeast instability is weaker and the impulse that is associated
with the higher pops will likely shear out before it moves
northeast across minnesota Sunday.

The second system is stronger than the first and will likely
generate a widespread area of showers and thunderstorms late
Monday, and into Tuesday. Models are fairly consistent with the
initial timing of this short wave moving across the upper midwest
Tuesday, and into early Wednesday. As said before, the weak flow
aloft will likely cause some timing issue on the departure of this
system. So I wouldn't guarantee Wednesday will be dry.

Past Wednesday, the weak flow aloft will abruptly end as a strong
west to east flow develops. This has been very consistent with the
models and even the ensembles over the past several days. As this
type of flow develops, fast westerly short waves will likely form
and quickly move across the northern tier of the nation. This is
the period where chances of severe weather return as wind shear
increases. Beyond the 7 day period, model trends have been
developing a large ridge building across the center of the nation.

Some of the models are even depicting a return to a more
southwest flow aloft. Temperatures over the next several days will
average near normal with highs around 80 and lows in the low to
mid 60s. Temperatures will likely begin to modify as the ridge
begins to build northward late next week. Thickness values and
85h temperatures will respond to the building ridge with highs
reaching the 90s once again by the end of next week.

Aviation (for the 06z tafs through 06z Friday night)
issued at 1048 pm cdt Thu jun 21 2018
mid-level clouds will continue to scatter out tonight, with
sct-bkn high clouds for Friday. Winds will be light and variable
into Friday morning, and then east southeast AOB 6 knots on Friday
afternoon eve.

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.
