What forecasters said that day

The local office's own words before this winter weather advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Gaylord, MI wrote its last area forecast discussion before this winter weather advisory went out at Apr 16, 3:37 AM EDT, 4 minutes earlier.

.NEAR TERM...(Today through Tonight)
Issued at 336 AM EDT Mon Apr 16 2018

...Winter not done yet...

Triple-point low over western VA is now the dominant surface low. A
sharp inverted trof extends up toward the southern tip of Lk Huron,
and a weak surface wave is present near Lapeer MI. High pressure is
anchored over ne Canada. A closed 500mb low will pass just south of
lower MI today. However, a shortwave will pinwheel back into the
northern lakes as this happens, and this will close off directly
over our heads this evening. This will help maintain an easterly
feed of moisture into the region, and give us some dynamics to act
on that moisture. In addition, 850mb temps of -13/-14C may allow a
lake response to develop. The end result is another pretty typical
mid-winter forecast.

Plume of deep moisture, now just grazing parts of ne lower and
eastern upper MI, will gradually get drawn back westward this
morning. Radar has already lit up substantially since midnight
with convective echoes over central/eastern areas. Expect precip
rates to increase again toward daybreak for APN/Rogers and on up
into far eastern upper MI. 500mb heights will sharply lower this
morning, and a weak surface low reflection will lift ne-ward
across Lk Huron. In response, snowfall rates in the areas
mentioned above will be legit heavy at times in the daylight
morning hours. Expect 2-4" of accums this morning/midday, along
and north of a CVX-GLR-Black River line.

This afternoon, a subtle mid-level dry slot will form in ne portions
of the forecast area, as a closed 500mb circulation emerges over the
Straits area. A rain/snow mix will enter the equation from Gladwin
to Harrisville and points south. Meanwhile, moisture will wrap back
into nw lower MI, along with the colder 850mb temps mentioned above.
Forcing is less than this morning, but it's getting cold enough for
Lake MI to help out. The above plays out thru tonight, though the
850mb thermal trof does start to ease southward late in the
overnight. Inversion heights settle in at 800mb, 5.0-5.5k ft. NW to
borderline WNW flow, when combined with lingering ice cover over the
ne tip of Lake MI, will focus better lake enhanced snow from midday
today into tonight in the Gd Trav Bay region. Afternoon accums of 1-
2" in nw lower, far n central lower, and eastern upper. That segues
to 2-4" tonight in much of nw lower MI, with lesser amounts
elsewhere.

Ongoing winter storm warnings are fine, except for Leelanau, which
won't get caught up in the early morning activity very much. They do
get involved by late morning and beyond as lake enhancement kicks
in. Will cancel the Leelanau warning, but will put them, Benzie, Gd
Traverse, and Kalkaska in an advisory that kicks in later this
morning and goes thru late tonight.

Lots of clouds. Max temps low-mid 30s. Min temps mid-upper 20s.

.SHORT TERM...(Tuesday through Wednesday)
Issued at 336 AM EDT Mon Apr 16 2018

...Moderating Temperatures...

High Impact Weather Potential...Minimal as the snow diminishes and
we get some light rain.

Pattern Synopsis/Forecast...The models show the lake effect snow
should diminish as the 850 mb temperatures warm t around -6c or so
by 00z/Wed, and that the 700-500 mb layer rh begins to dry out
allowing for some <50% RH air in the layer. This leads to a
temporary reprieve of the last few days, with Tuesday night into
Wednesday morning being dry. However, an Alberta clipper system
drops through the Northern Plains and brings some WAA snow and
rain/freezing rain Wednesday afternoon and into Wednesday night. The
sfc low moves into New England by 12z/Thu and the dry air in the 700-
500 mb layer returns into the Upper Great Lakes.

Primary Forecast Concerns...Not sure I buy the blends idea of
freezing rain for Wednesday night. Maybe we get patchy drizzle and
temperatures cool to just below freezing so that we get some
freezing drizzle. The ECMWF soundings for Wednesday night are pretty
dry and the QPF is very low. The NAM and the GFS both really push
some sort of rain/drizzle with the sfc temperatures around 32F. so
will have to watch this. The impacts at most would be a slippery
morning commute on Thursday, but nothing that would raise a
headline. I'm willing to go out on a limb and side with the ECMWF of
little to nothing for the Wednesday night. We'll have to see how
strong the Hudson Bay high is and whether it can push some low level
dry air to keep the warm front from producing much.

.LONG TERM...(Wednesday night through Sunday)
Issued at 336 AM EDT Mon Apr 16 2018

...Becoming precip-free with Moderating Temperatures...

Extended (Thursday through Sunday)...The models dry things out
through the weekend, as High pressure builds into the Upper Great
Lakes at the sfc and aloft. Lots of dry air pushes into the region
as a result and the 500 mb heights begin to build. This pushes our
temperatures up from the lower 40s on Thursday to the lower 50s on
Sunday. It would be surprising if, with the sunshine that one would
expect with this pattern that we could get back to the normal high
temperatures for this time of year which are the mid to upper 50s.

.AVIATION...(For the 00Z TAFS through 00Z Monday evening)
Issued at 711 PM EDT Sun Apr 15 2018

Large area of low pressure will continue to slowly work eastward
through the Great Lakes over the next 24 to 36 hours. Just
scattered precipitation at MBL/TVC this evening, with
precipitation more widespread at APN/PLN.  Still a variety of
precipitation types tonight with light rain, snow, freezing rain
and sleet possible. As colder air wraps in from the northwest late
tonight into Monday, precipitation will transition back toward
all snow. Cigs/Vsbys ranging from IFR to MVFR tonight, with IFR
conditions more likely late tonight into Monday as more widespread
precipitation once again develops across the area. Winds remaining
gusty from the northeast tonight, with the highest gusts gradually
diminishing. Winds will shift to the north/northwest late tonight
into Monday.

.MARINE...
Issued at 336 AM EDT Mon Apr 16 2018

Blustery ne winds will continue to back to the n and nw, while
remaining gusty. Advisories will likely be extended for a lengthy
period, perhaps into Tuesday.
