Update For 18z aviation discussion below.

Short term (today and tonight)
issued at 239 am cdt Wed apr 25 2018
early morning IR imagery with surface obs and rap analysis showed
clear skies and light winds across the region. And area of high
pressure was located from south dakota through northern minnesota.

Today the high pressure will slowly sag to the southeast so should
see northerly winds go calm and eventually take on a light
southerly direction. Expect plenty of Sun today. Tonight a pv
anomaly will drive a cold front through the region. This system is
weakening, but should see a few rain showers develop along it and
move in from the northwest.

Long term (Thursday through Tuesday)
issued at 239 am cdt Wed apr 25 2018
the weakening frontal boundary will bring clouds and a chance for
some light rain showers on Thursday, but most locations should
stay dry. If they do see precipitation, amounts should be less
than a tenth of an inch. High pressure will build in for Friday
and Saturday.

Meanwhile a large upper level ridge will build upstream while a
low develops over the west coast. This low attempts to undercut
the ridge and bring southwest flow across the upper midwest. This
will bring warmer temperatures and increase the boundary layer
moisture. The mid level lapse rates are quite impressive, on the
order of 7.5 to 8.5 c km, and together with the jet aloft will
give us a CAPE shear profile capable of thunderstorms and perhaps
some severe weather. It is too early to for timing, and at this
point the moisture seems limited for widespread severe weather.

None the less, a more active weather pattern continues to look
more likely for next week.

Aviation (for the 18z tafs through 18z Thursday afternoon)
issued at 1200 pm cdt Wed apr 25 2018
vfr trends through period. Some lowering CIGS with incoming cold
front later tonight into Thursday. Should be any lower than
35-4500ft though. Rain chance is small but did include some vcsh
over northern mn portion of the area. Expect surface winds to
become s-sw into tonight and gusty NW with fropa.

Kmsp... Problematic light winds early should become sw-s into
tonight and FROPA expected by 16z or so. Will continueVFR trend
and mention vcsh for possible virga sprinkles around before noon
or so. Winds will become NW and gusty into the afternoon.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
