243 pm cdt Fri jul 19 2019

Short term (this evening through Saturday)
issued at 243 pm cdt Fri jul 19 2019
severe weather potential for east-central mn and northwest
wisconsin this afternoon into early evening. All modes of severe
weather will be possible - see latest hazardous weather outlook
for details. (apologies for the brief discussion due to past,
present, and future severe weather keeping us a little busy today!)
storms could clear out quickly west to east tonight with clearing
skies late tonight. Lows as cool as the low 50s in northern
minnesota as drier air moves in, in the low 60s in northwest
wisconsin.

Mainly sunny and nice on Saturday with highs in the upper 70s and
much more comfortable dew points in the 50s. A low chance for a
few showers across east-central mn and northwest wisconsin, but
very low potential for thunderstorms, and showers won't last all
that long if they do develop.

Long term (Saturday night through Friday)
issued at 243 pm cdt Fri jul 19 2019
zonal flow will be in place in Sunday with a shortwave diving
through the upper midwest Sunday afternoon into early Monday
morning. This may lead to a few showers and storms, mainly across
our western zones. Northwest flow will then set-up for the remainder
of the extended. This will bring periodic rainfall chances through
the week, but no significant systems are expected through the
period. Sunday and Monday will see temperatures in the 70s to near
80 with 80s for most areas for the remainder of the week.

Aviation (for the 18z tafs through 18z Saturday afternoon)
issued at 1236 pm cdt Fri jul 19 2019
vfr cloud decks are seen at all sites early this afternoon with
light showers in the hib, inl, brd and dlh areas. These showers
may linger in spots before additional storm development is
expected, mainly at brd and hyr, after 4pm 21z. Storms may be
severe with damaging winds and large hail, with a few tornadoes
possible in the brd area. Refinements to timing are expected once
development becomes clearer as uncertainty still exists. In
addition to MVFR ceilings in storms, visibility restrictions to
mfvr ifr will be possible.

Marine
Issued at 243 pm cdt Fri jul 19 2019
outside of the potential for a few thunderstorms this afternoon and
evening along the south shore of lake superior, no hazardous
conditions are expected over the next 48 hours. Storms this
afternoon evening may contain wind gusts to 40 to 50 knots. Winds
through Saturday will be generally westerly, but run southwest to
northwest at times. A few gusts to around 12-15 knots will be
possible during the day on Saturday. Waves will be 2 feet or less
through the period.

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.
