537 pm cst Wed nov 14 2018

Short term (this evening through Thursday)
issued at 140 pm cst Wed nov 14 2018
a deepening area of low pressure will cross to the north of lake
superior - this will increase winds this evening and also bring a
threat for snow and possibly patchy freezing rain at precipitation
onset Thursday. QPF amounts are light with only a tad more than a
tenth of an inch of liquid equivalent expected which translates to
an inch or two of snowfall across northern mn. NW wi doesn't see
as much qpf, so snowfall amounts are only a 1 2 an inch there. In
the wake of this low, lake effect snow is likely over NW wi.

Added a marine section to the afd to highlight gales.

Long term (Thursday night through Wednesday)
issued at 140 pm cst Wed nov 14 2018
lake effect snow along the south shore of lake superior will be
the main forecast parameter to begin the long term. Northwest
winds will spark lake effect snow showers as they bring cold air
across the warm, big lake. However, the pressure gradient only
warrants a short period of these showers as the flow is quite
progressive.

High pressure builds for Saturday and most of Sunday. A weak
trough of low pressure accompanying an upper level wave slides
through on Sunday night into Monday - again low qpf, but this will
bring a burst of cold air with lows dipping into the single digits
above below zero. Another clipper system mid week. Overall, a
fairly quiet forecast in terms of large systems.

Aviation (for the 00z tafs through 00z Thursday evening)
issued at 537 pm cst Wed nov 14 2018
vfr at the start of this forecast with a batch of cirrus
overspreading the terminals. A low level jet is moving overhead
and creating some llws that affects each terminal through at least
06z, when the low level jet moves away. As an area of low pressure
moves through south central canada, additional clouds will arrive.

MVFR CIGS vsbys, with some snow showers, will begin to move
across inl hib dlh terminals by mid morning in assocaition with
the surface low.

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.
