Short term (today through Tuesday)
issued at 305 am cdt Mon may 29 2017
a semi-vertically-stacked area of low pressure over northern
ontario will not be moving anywhere in a hurry through Tuesday. It
will mainly spin and slowly drift north and east through ontario.
This low will maintain cool, humid, and breezy west-northwest flow
across the northland. Multiple shortwave troughs will drop through
the area, helping to develop rain showers.
Today will be the wetter and breezier day. Scattered showers will
develop across the northland by late this morning. The gfs, nam,
rap, and SREF indicate there will be up to a few hundred j kg of
mucape over the higher terrain of the arrowhead, and in the far
southeast forecast in northwest wisconsin. These areas could see
some isolated, weak thunderstorms. Expect highs in the middle to
upper 50s, with afternoon gusts of 15 to 25 mph. There could be
stray gusts to 30 mph with the heavier showers and the storms.
The showers will taper off this evening around and after sunset.
Another shortwave trough will probably spread additional showers
out of canada into northern minnesota later in the night.
Tonight's cloud cover will bolster temperatures to the lower 40s.
Tuesday will be a similar story to Monday, but not quite as wet
and windy. Also, the threat of thunder looks very low.
Long term (Tuesday night through Sunday)
issued at 305 am cdt Mon may 29 2017
the upper level trough will continue to move east Tuesday night
into Wednesday with northwest flow over the region. A low level
ridge will be in place over western minnesota eastern dakotas by
Wednesday afternoon but will weaken as it moves east into
Thursday. There will be a chance for showers Tuesday evening over
eastern portions of the northland and over the arrowhead Thursday,
but most other areas will be dry. Highs Wednesday will be in the
mid sixties to around seventy... And in the upper sixties to mid
Friday also looks like a dry day with shortwave ridging over the
northern plains and a surface ridge extending south into the
region. Highs will range from the mid sixties to lower seventies
but be cooler around lake superior as off lake winds develop.
The models start to diverge in their solutions over the weekend
and confidence is lower than normal into early next week. The
differences are in how they treat a northern stream shortwave that
will start to affect the region Saturday continuing into Sunday.
The GFS is now stronger with the shortwave but also seems to be
suffering from convective feedback as the wave continues into
minnesota. The ECMWF which had a stronger low wave with previous
runs is now weaker and keeps much of the area dry through the
weekend with high pressure. We have a chance for showers and
thunderstorms in the forecast over the weekend over portions of
the northland but overall confidence in one model is low.

widespread MVFR ceilings will cover the terminals through much of
the forecast. Some periods ofVFR are possible at brd as these
ceilings are just off to the west of brd at the start of the
forecast. Ifr is feasible in the vicinity of rain showers along
with some br. Gusty winds are expected through this evening before

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.
