Short term (this evening through Monday)
issued at 403 pm edt Sun sep 23 2018
wv imagery and rap analysis indicated a shortwave trough moving
through the northern rockies with nearly zonal mid upper level flow
downstream across the rest of the northern conus. At the surface,
the cold front that moved through most of upper michigan last night
has stalled near kesc-kimt. Abundant low clouds persisted across the
north with temps in the mid to upper 40s while sct-bkn CU prevailed
over the south allowing temps to climb into the lower to mid 60s.

Upslope easterly flow into north central upper michigan still
supported some patchy drizzle in the higher terain along with some
fog.

Tonight, a southerly low level jet will increase over the area
tonight in response to deepening low pressure ahead of the advancing
nrn rockies shrtwv. Some pcpn may develop with the WAA pattern but
models 295k-305k isentropic progs suggest that mid level moistening
will remain north of upper michigan with mainly just low level
moisture persisting. So, no more than drizzle would be expected
where SE to S flow upslopes, especially over the NRN keweenaw
peninsula. Otherwise, temps will remain steady or slowly rise
tonight north as the winds veer.

Monday, any remaining low clouds or fog should dissipate during the
morning as low level mixing increases. Sunshine and WAA with gusty
southerly winds to around 25 mph will help push temps to around 70,
especially where downslope flow prevails near lake superior.

Long term (Monday night through Sunday)
issued at 339 pm edt Sun sep 23 2018
no significantly impactful weather expected in the long term as
fairly typical fall conditions persist.

A low will pass N of the cwa, dragging a cold front trough across
the area Mon night into Tue morning. Best resulting rain coverage
should be over the western cwa, with more scattered coverage
elsewhere.

A couple of shortwave troughs moving through the region Tue evening
and Wed may bring some rain showers, but coverage is uncertain.

850mb temps drop down around 1-2c Tue night and wed, so wnw winds
may lead to some isolated to scattered showers downwind of lake
superior.

A stronger trough will then move through the area thu, bringing
chances for showers Thu into Thu night. Lake effect rain showers are
possible Fri as models show wnw flow with 850mb temps around or less
than 0c.

Lots of uncertainty next weekend as models differ significantly, but
could see continue off and on chances for rain.

High temps of 55-65 Tue will fall into the 50s for the most part wed
through Sun (may not even get above 50 in spots Fri and sat. Lows
over the interior will be in the 30s Tue night through Sat night,
with Fri and Sat night looking coldest. Frost will be possible at
times, but potential will need to be fine tuned as precip and cloud
cover can be better sorted out.

Aviation (for the 06z tafs through 06z Monday night)
issued at 138 am edt Mon sep 24 2018
abundant low-level moisture and upslope winds will support ifr lifr
conditions through tonight at kcmx ksaw.VFR conditions will
continue at iwd through most of the period and then rain and MVFR
conditions move in for Mon night. Kcmx will quickly improve toVFR
late tonight. Ksaw will maintain upsloping tonight but should
improve to MVFR early Monday morning as winds become southerly and
vfr by mid morning before MVFR conditions return by Mon evening.

Marine (for the 4 pm lake superior forecast issuance)
issued at 403 pm edt Sun sep 23 2018
another cold front will approach from the west on mon, and this will
keep winds mostly in the 20-30kt range, though the strongest winds
will shift to eastern lake superior tonight and Mon as winds become
southerly. There could be some gale force gusts over the eastern
part of the lake on mon. With passage of the cold front mon
night early tue, winds will shift to the NW at 15-25kt for tue,
strongest over the E half of the lake. May be able to slip in a day
with winds mostly under 20kt on Wed before the next low pres system
moving E toward northern ontario brings stronger winds of 20-30kt
again on thu.

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.
