529 am est Mon nov 20 2017

Short term (today and tonight)
issued at 248 am est Mon nov 20 2017
upper air pattern consists of a 500 mb trough in the ERN u.S. This
morning and a trough off the pacific NW coast and another in the
canadian rockies. This trough in the canadian rockies digs quickly
southeast into the northern plains tonight and is poised to move
into the upper great lakes. Did not make too many changes to the
going forecast overall and looks pretty quiet as lake effect snow
ends over the east and starts up late tonight again as colder air
comes in late. Will have filtered sunshine through high clouds today.

Long term (Tuesday through Sunday)
issued at 437 am est Mon nov 20 2017
a sfc low NE of the CWA Tue morning will already have dragged a cold
front across the CWA by 12z tue, with a secondary trough front and
shortwave moving through late morning and early afternoon tue. A
second shortwave crosses the area late Tue into early Tue night.

850mb temps around -8c at 12z Tue will drop to -15c by Tue afternoon
and stay that cold through Tue night. Winds will be gusty out of the
nw, with gusts to 40-45mph along the lake superior shore and up to
30mph elsewhere.

Moderate les is expected to develop Tue morning in the NW winds
snowbelts and continue through Tue night before warming temps and
winds becoming W to SW will diminish les on wed. Heaviest snow
should be with the secondary front trough shortwave from late tue
morning into Tue afternoon. Another uptick in les can be expected
with the second shortwave. Dry air looks to limit total
accumulations some with forecast amounts generally of 2-5" in nw
snowbelts Tue into wed. Could see some advisories issued, if
anything.

Looks like a decent shot of seeing over much of the area on Friday
as a low moves N of the area. On the back side of the system sat
into sun, which would lead to light to moderate les in the NW wind
snowbelts.

Aviation (for the 12z tafs through 12z Tuesday morning)
issued at 528 am est Mon nov 20 2017
vfr conditions will prevail thru the fcst period.

Marine (for the 4 am lake superior forecast issuance)
issued at 248 am est Mon nov 20 2017
an area of low pressure will approach, then move through the area
tonight through Tuesday giving a period of southwest gales tonight
before shifting to northwest gales Tuesday into Tuesday night. The
next chance of seeing near-gale winds will be Friday into Saturday;
otherwise, winds are generally expected to be in the 15 to 25 knot
range.

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.
