Short term (this evening through Friday)
issued at 416 pm edt Thu mar 21 2019
wv imagery and rap analysis indicated a mid upper level ridge from
the central plains to alberta and a trough from northeast canada
into the SE CONUS resulting in nnw flow toward the northern great
lakes. A shortwave trough was moving into NRN lake superior bringing
clouds and some light pcpn into eastern lake superior. Otherwise,
breezey west winds under mostly sunny skies has pushed temps into
the mid and upper 40s over most of west and central upper michigan.

Tonight, fcst 700-300 mb qvector conv with the shrtwv and
radar satellite trends suggest suggest that the light rain and snow
showers will move through the area between 21z-00z. QPF toward
neweberry should remain less than 0.10 inch. Enough cold air with
850 700 mb temps of -12c -18c and deeper moisture will drop
through lake superior to support some light les for north flow
favored locations. Winds will also become blustery near lake
superior with gusts to around 30-35 mph.

Friday, any lingering light les will diminish during the morning as
dry air quickly moves in with inversion heights dropping at or below
3k ft. Even with mostly sunny skies in the afternoon, temps will
struggle to near 30 north and the lower to mid 30s south.

Long term (Friday night through Thursday)
issued at 310 pm edt Thu mar 21 2019
high pressure will initially grace the area with its presence at the
start of this forecast period, allowing for benign weather
conditions to prevail tomorrow night into Saturday. As high pressure
drops to the southeast late Saturday, a quick-paced
clipper associated frontal boundary will march through the u.P. On
Sunday. That said, this doesn't appear to produce much with little
qpf anticipated overall. Once it completes its passage late Sunday,
look for another round of high pressure to take over on Monday, with
benign weather once again prevailing into the middle of next week.

By Wednesday, deterministic models are generally agreeable on that
being the next chance for precip as a low pressure system tracks
across northern ontario.

As for precip types during these two lower-end events, model
soundings and thermal profiles are pointing toward a wintry mix on
Sunday, with rain snow primarily dominating and perhaps some sleet
mixing in. With temps lingering near the freezing mark in the
northern portions of the u.P., any rain that does fall may freeze on
any remaining sub-freezing surfaces, but with temps as warm as
they've been as of late, ice accums will be very limited and likely
unimpactful. And again, QPF amounts are anticipated to be on the
light side, less than a tenth area-wide. Regarding the middle of
next week (Wednesday), temps initially will be supportive of wintry
precip, but should quickly transition over to rain everywhere as
temps rise well above freezing.

Speaking of temps, the chilliest day of the forecast period will be
on Monday with highs topping out in the upper 20s to lower 30s.

Otherwise, temps will remain near or above normal this weekend into
next week, with highs flirting with the 50s for many on Saturday.

Aviation (for the 06z tafs through 06z Friday night)
issued at 1239 am edt Fri mar 22 2019
as increasingly colder air flows into the area overnight along with
low-level moisture, expect CIGS at kiwd kcmx ksaw to settle to high
MVFR or lowVFR. MVFR CIGS are more likely to occur at ksaw. In
addition, expect isold sct light lake effect -shsn flurries into the
morning hrs, mainly at ksaw. Vis restrictions are unlikely, but the
-shsn may drop vis to MVFR briefly. Expect clouds to clear out from
nw to SE during the aftn. Winds will be gusty to 20-30kt thru this
aftn, mainly at kcmx ksaw.

Marine (for the 4 pm lake superior forecast issuance)
issued at 416 pm edt Thu mar 21 2019
a few gale force gusts are expected at times late tonight into
Friday morning, mainly over south central lake superior. Winds calm
below 25 knots across the lake Friday night and stay there through
the middle of next week.

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.
