Area Forecast Discussion
National Weather Service Gaylord MI
243 AM EDT Mon May 4 2026

.KEY MESSAGES...

-Elevated fire weather danger today.

-Showers track across the northwoods this evening.

-Seasonably cool temperatures Tuesday through the rest of the week
will consistently bring frost/freeze concerns across Northern
Michigan.

.DISCUSSION...
Issued at 242 AM EDT Mon May 4 2026

Pattern Synopsis:

A 500mb closed low pressure system remains over Hudson Bay with deep
longwave troughing extending southward into the northeastern CONUS.
Embedded shortwave ridging over the Great Lakes Region today will
advect warm air from the southeast as H8 temperatures remain around
8-10C. Mixing down to the surface, adiabatic heating processes and a
lack of atmospheric moisture will result in highs in the low/mid 70s
today and critically low RH values.

Previously mentioned troughing with its axis extended through the
Minnesota/Dakota region will develop surface low pressure and sweep
a strong thermal gradient cold front across Northern Michigan. After
showers depart the region overnight, the aforementioned trough axis
will shift eastward and settle over the Great Lakes region. Cool cP
air influence with 850mb temperatures below freezing will continue
climatologically cool weather this Tuesday through the rest of the
week. Daytime highs will remain in the 40s and 50s while overnight
lows near freezing will continue Frost/Freeze concerns for
vegetation.

Forecast Details:

Elevated fire weather danger today... The aforementioned warm air
advection associated with the shortwave ridge will begin to surge
into the area today. Model soundings will begin to saturate from the
top of the profile downward with very high dew point depressions at
the surface, creating an “inverted V” profile. Low level jet
development moves over Lake Michigan with 40kt winds by noon.
Efficient daytime mixing will transport strong wind gusts to the
surface along with further lowering dew points to the low 30s.
Minimal RH values and winds will continue elevated Fire Weather
wording along with wind gusts reaching 30 to 40mph this afternoon
through 00Z Tuesday.

Showers and storms this evening...Strong surface low pressure to the
Northwest with attached cold frontal boundary remains moisture
starved even with strong southwest flow during the day. Midlevel
lapse rates will provide enough instability to produce convective
driven showers to sweep across the region. Showers will begin as
early as this evening when saturation aloft finally overcomes dry
surface conditions. Only QPF totals of 0.10” or less is expected
across the CWA.

Seasonably cool weather with Frost/Freeze beyond Tuesday...The
previously mentioned shortwave will progress southeast and position
its axis over Northern Michigan as surface low pressure departs
northeast. Cold cP surface air influence and sub-freezing H8
temperatures will then occupy the CWA this Tuesday through the
remainder of the week. Even with high pressure and overall
precipitation-free conditions this Tuesday through Thursday,
adiabatic heating to the surface will result in highs in the upper
40s and 50s through Friday while overnight lows fall to the mid to
low 30s. The biggest concern at this time remains the continuation
of frost and freeze threatening sensitive vegetation during these
early stages of the growing season. Lingering low-level moisture
will keep some scattered showers in the forecast toward the end of
the week as embedded weak energy waves track through the region, but
little to no QPF is expected at this time.

.AVIATION /06Z TAFS THROUGH 06Z TUESDAY/...
Issued at 1205 AM EDT Mon May 4 2026

Largely VFR through the night, though may contend with some BR /
FG at PLN and / or CIU. S to SW winds really ramp up into the
day Monday, gusting as high as 35 to 40kts from late morning
through the afternoon, strongest in the northern lower TAF
sites. Cold frontal boundary will reintroduce SHRA and perhaps
even TSRA into the picture Monday evening, some of which could
be quite gusty considering high cloud bases. A cold front will
pass through, turning winds N later in the evening, and with
that colder air, CIGs will start a downward journey of
prevailing conditions falling below VFR beyond the forecast
period.

...Elevated fire danger across northern lower Michigan today...

Gusty southwest winds and low relative humidity will lead to
elevated fire danger today. Winds of 10 to 20 mph and frequent gusts
of 25-35 mph will be seen over much northern Michigan late this
morning through this afternoon. Minimum relative humidity values of
20-35 percent are expected over much of northern lower Michigan.
These conditions could lead to rapid spread of fires. Check burning
restrictions and fire danger before burning.

For more information on burning restrictions for Michigan, see
www.dnr.state.mi.us//.
