Area Forecast Discussion
National Weather Service Gaylord MI
320 PM EDT Sun May 27 2018

.NEAR TERM...(Through Tonight)
Issued at 257 PM EDT Sun May 27 2018

...Thunderstorms This Evening...

High Impact Weather Potential...Thunderstorms will again affect
portions of N Lower (mainly NE Lower) with small hail and gusty
winds possible.

Pattern Synopsis/Forecast...The wind shift/convergence line is now
from about the mid-Lake Huron buoy to Mio to HTL, to RQB. This is
expected to move east through the afternoon/evening, triggering
showers/thunderstorms along it, into the early evening. Models are
pushing the rain/thunder out into Lake Huron, and out of the
forecast area by 02z/Mon, so will go with thunder through 02z,
then quiet overnight.

A MCS approaches the Upper Great Lakes and moves into N WI/W Upper
by 12z/Mon. So will keep the night dry with the main action
upstream. Of course, the models quickly cause this system to fall
apart by 15z as it crosses Lake Michigan.

Primary Forecast Concerns...Main concern is the thunderstorms this
evening and tonight. HiRes-W models, the HRRR, and NAMNest and
DNG all have this feature and the thunderstorms moving through the
SE counties and out of the region, around 00z, maybe 02z with the
slower models. This looks to be a good timing and maybe even a
little slow considering the current line. So will have the rain
chances with scattered to isolated thunderstorms through 00z.

&&

.SHORT TERM...(Monday through Wednesday)
Issued at 257 PM EDT Sun May 27 2018

High Impact Weather Potential: Elevated fire danger concerns
Tuesday. Heavy rainfall potential could start as early as Wednesday
evening, but likely more of an issue Thursday.

Pattern Synopsis/Forecast: Ridging will once again build into the
region Monday, with a broad area of deep troughing west of the
Rockies. The most notable feature will of course be Alberto in the
Gulf Coast area, with NHC currently predicting landfall Monday
afternoon. Things get a bit interesting as the remnants of Alberto
work north early in the week through the broad area of high pressure
and ridging over the eastern CONUS. As the remnants move north, and
the western troughing works east, there is rather good agreement
that the two features phase early Wednesday. This will accelerate
the northward movement of those remnants, and likely bring it to our
doorstep. There is good agreement that this feature will be just to
our south Wednesday evening, but poised to move overhead as early as
Wednesday night. Things could of course speed up or slow down, so we
will see how things develop as Alberto makes landfall.

Primary Forecast Concerns: Prior to the arrival of the heavy
rainfall potential with the remnants of Alberto, the primary
concerns will be shower potential with a weak cold front and
elevated fire danger Tuesday. Temperatures will continue to run well
above normal, with many areas seeing 90s Monday. The aforementioned
cold front will knock temperatures down a bit Tuesday but not by
much and many spots will still be in the mid 80s, perhaps higher on
the west side of the state with some downsloping easterly flow.
Lowered dewpoints a bit on Tuesday as blends looked a bit high,
perhaps as much as 10 degrees. With good mixing potential under
clear skies and winds picking up a little bit with the front, as
well as high pressure sitting near Hudson bay, it seems like a prime
time for the blend to under perform with dewpoints. With adjustments
it still doesn't quite hit critical fire weather thresholds, but it
is close and if high temperatures get a bit higher we could easily
be there. Toss in a brief period of gusts creeping over 10kts and we
will likely see a period of elevated fire danger.

&&

.LONG TERM...(Wednesday night through Sunday)
Issued at 257 PM EDT Sun May 27 2018

...Heavy rainfall potential...

The remnants of Alberto will be the primary concern for the extended
period. As mentioned by the previous shift, the PWAT values
currently progged to be overhead are +3 to 4 standard deviations
above normal for this time of year, and could push into record
territory comparing currently forecasted values to the sounding
climatology. We could see a few thunderstorms as the system passes
as well. There are still plenty of details to work out for just
where things will line up, and how quickly we clear out, but things
should start to clear up a bit as Alberto actually makes landfall.
Temperatures will start to lower a bit as we get into the end of the
week and through the weekend, but will still remain above normal.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 243 PM EDT Sun May 27 2018

Main concern is the convective risk today and into Monday. The
main wind shift/convergence line looks to have just cleared APN
and is continuing east, into Lake Huron. This leaves thunderstorms
moving through the rest of NE Lower MI This afternoon/evening
before this threat ends. However for the TAF sites, PLN, TVC, and
MBL, should remain rain free through 12z/Mon as the main trigger
is east, and the next threat isn't until after 12z/Mon. APN has a
small chance, but considering that the SHRA/TSRA TRigger line is
now past APN, think that the small chance will diminish quickly
into the afternoon.

As mentioned the next threat is after 12z/Mon as a complex of
thunderstorms moves into N WI/W Upper. However, the models that
have this complex, cause the thunderstorms to fall apart over N
Lake Michigan, before affecting TVC/MBL. That will be something to
keep an eye on, but for now think that NW lower will remain rain
free.

&&

.MARINE...
Issued at 257 PM EDT Sun May 27 2018

Winds will remain light and generally out of the south to southwest
through Monday evening. An approaching cold front will begin to
shift winds around to the north to northwest Monday evening and into
the overnight, and continue shifting more easterly through the day
Tuesday. Gusts will also pick up a bit Tuesday, getting into the 10
to 15 knot range. There is a slight chance for some showers or
thunderstorms to initiate as the front passes Monday night.
