National Weather Service Marquette MI
631 PM EDT Fri Mar 16 2018

.SHORT TERM...(This evening through Saturday)
Issued at 245 PM EDT FRI MAR 16 2018

Expect continuation of quiet weather through Saturday as high
pressure slides across the Upper Great Lakes. Went on lowest end of
guidance for lows tonight with the high overhead and clear skies.
Seems we could see lows into the lower single digits inland west.
Highs on Saturday under mostly sunny skies could reach upper 40s
west and scntrl. Coolest temps Saturday in the lower 30s will be
found over the east near Lk Superior with light north winds and
potential for some broken mid level clouds at times. Overall though
no high impact weather is expected.

.LONG TERM...(Saturday night through Friday)
Issued at 245 PM EDT FRI MAR 16 2018

Split flow pattern prevails through next week with stronger systems
staying well to the south and east of the Upper Great Lakes. Main
weather feature over the region will be sfc high pressure staying
anchored in the vicinity of Hudson Bay. If this were later in the
Spring, this would be a drying fire weather pattern. Still have good
deal of snow on ground over much of Upper Michigan at this time
though. Only real system early on is a weak backdoor cold front
dropping across the area on Sunday as high pressure builds over
Hudson Bay. The front and some limited low-level moisture may bring
some flurries over northern and eastern Upper Michigan on Sunday.

Suppose there could be some flurries at times Monday into Tuesday
with east to northeast winds and h85 temps down to -12c. Instability
will be only marginal for LES though and overall moisture is lacking.
Overall looks like it stays pretty quiet. After some warmer temps
this weekend, temps will fall back below normal with highs from the
upper 20s north to lower 30s south. Normal highs are in the mid 30s
north and the upper 30s south.

Cooler weather lingers through mid week with upper level troughing
overhead and as H85 temps drop slightly in response to sharpening
sfc-H85 northeast flow btwn stronger low pressure system affecting
northeast Conus and the persisting Hudson Bay high pressure.
Probably will see at least isolated snow showers/flurries Wednesday
aftn and Thursday afternoon. Coverage of snow showers will increase
with any more notable shortwave moving through to increase larger
scale lift. By next Thursday and Friday looks a bit warmer than
earlier in the week with temps at or even slightly above normal.
Next chance of widespread precipitation could move in next weekend.

.AVIATION...(For the 00Z TAFS through 00Z Saturday evening)
Issued at 631 PM EDT FRI MAR 16 2018

VFR conditions will continue at all sites through the period.

.MARINE...(For the 4 PM Lake Superior forecast issuance)
Issued at 245 PM EDT FRI MAR 16 2018
