Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0751 PM CDT Fri May 29 2020

Valid 300100Z - 301200Z

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF
THE NORTHEAST STATES...

...SUMMARY...
Scattered severe thunderstorms primarily capable of producing
damaging winds will continue across parts of the Northeast states
this evening.

...Northeastern States...

Weak mid-level height falls will spread across the northern Middle
Atlantic this evening ahead of the short-wave trough ejecting across
the Ohio Valley. A corridor of untapped instability currently
resides across the Middle Atlantic from VA into southeastern PA
where MLCAPE values range from 1500-2000 J/kg. Scattered convection
is approaching this reservoir of buoyancy and vertical shear remains
strong -- supportive of organized updrafts. 00z sounding from RNK
has sampled the convective generation zone well and this profile
supports maintaining SLGT Risk across this region until
thunderstorms spread toward the Atlantic Coast. For more information
on this scenario, reference MCD # 763.

Farther north across New England, organized convection is
progressing across northern NH into northwestern ME where a narrow
axis of instability remains. Locally damaging winds can be expected
for the next few hours with this activity.

Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1230 PM CDT Fri May 29 2020

Valid 301200Z - 311200Z

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF
THE PACIFIC NORTHWEST...

...SUMMARY...
Widely scattered severe thunderstorms are expected Saturday
afternoon/evening particularly across the Pacific Northwest, with
isolated severe risk arcing from there southeastward across the
northern and central High Plains.

...Synopsis...
While broad upper troughing shifts slowly eastward across the
eastern half of the U.S., an upper low is forecast to move
north-northeastward across northern California and the Pacific
Northwest on Saturday. In between, ridging will prevail over the
Intermountain region.

At the surface, a cold front will advance slowly eastward across New
England and the Atlantic Coast states. In the West, a compact
surface low will shift northward across the Pacific Northwest ahead
of the upper system, while an arcing lee trough persists across the
northern and central High Plains.

...Pacific Northwest...
As ascent increases across Oregon and Washington through the day,
ahead of the upper low, thunderstorms are expected to develop within
a destabilizing environment as diurnal heating of a relatively moist
low-level airmass yields moderate (generally 1000 to 2000 J/kg)
mixed-layer CAPE across parts of central Oregon and into Washington.
Enhanced southerly flow through a deep layer will yield not only
ample shear for organized/rotating storms, but also fast storm
motions, with upscale growth into northward-moving clusters
expected. Along with risk for hail, locally damaging winds are
expected, as storms shift northward through the afternoon and
evening hours.

...Western Montana and across the northern/central High Plains...
Showers and scattered thunderstorms are expected to develop in an
arc-shaped zone around the periphery of the upper ridge during the
afternoon as modest diurnal destabilization occurs, with development
aided by easterly/southeasterly low-level upslope flow.
Moderate/anticyclonic westerly/northwesterly winds aloft will
contribute to ample shear, such that a few storms may reach severe
levels, capable of gusty/damaging winds and hail locally. Storms
should continue into the evening hours, before diminishing
overnight.

...Coastal Carolinas/southeast Virginia...
Scattered thunderstorms -- and perhaps a storm or two nearing severe
levels -- are expected during the afternoon near/ahead of the
advancing cold front, and near sea-breeze boundaries. While shear
is expected to be weak, and thus storms largely disorganized, an
isolated gust or two capable of tree damage may occur, before storms
diminish by early evening.

Area Forecast Discussion
National Weather Service Gaylord MI
919 PM EDT Fri May 29 2020

.UPDATE...
Issued at 919 PM EDT Fri May 29 2020

Secondary cold front is moving into our western CWA late this
evening...ushering in significantly cooler air and a mainly broken
low cloud deck. Remnants of diurnal showers and storms across our
eastern CWA are exiting into Lake Huron attm...diminishing as they
do with with loss of diurnal instability. A few showers have
popped up within the low cloud deck over Upper Michigan and
Wisconsin...and certainly cannot rule out some of these will
drift thru our area overnight. Have reworked POPs and cloud cover
for overnight to increase both...but still expect most locations
will remain dry but partly to mostly cloudy overnight.

Temps will be noticeably cooler tonight...but certainly not cold
enough to worry about frost potential. (We`ll save that worry for
tomorrow night.) Low temps will fall into the 40s across our
entire CWA overnight.

&&

.NEAR TERM...(Through Saturday)
Issued at 336 PM EDT Fri May 29 2020

...Getting cooler...

High Impact Weather Potential...Low. Maybe a few rumbles of
thunder thru early evening. High swim risk possible on some ne
lower MI beaches Saturday.

Rain band has departed ne lower MI. Strong surface heating and
cooling temps aloft have allowed showers to develop in the wake
of the departing rain. As expected, coverage is highest in s
central and se sections. But a few showers have popped elsewhere,
especially in central/eastern Mack Co into se Chip Co in upper
MI.

Ongoing showers in northern lower/eastern upper MI have a clear
diurnal component, and will fade away this evening. However, this
will be a somewhat slowed/delayed process, as steep mid-level
lapse rates are maintained. Some showers could linger near OSC and
Standish thru 9 pm or so. Meanwhile, showers are also trying to
bubble up in central/western upper MI. Remnants of these will try
to move into nw lower MI this evening, and models continue to
advertise that they should have some limited success in doing so.
Will continue to have a small chance of showers this evening in
parts of nw lower MI.

A secondary cold front is dropping across northern Superior this
afternoon. This will cross northern MI late tonight and early
Saturday. High pressure will then build into the upper MS Valley
and western Great Lakes. 850mb temps will cool to a couple degrees
either side of 0C by early Sat afternoon. Occasional cyclonic
curvature to the low level flow will interact with very marginal
lake instability to produce some clouds and small chances for rain
showers. This will occur in western/central Chippewa Co tonight,
and in the same area plus much of nw lower MI Sat morning. The
afternoon looks dry.

The secondary cold front will also bring breezier nw winds.
Winds/waves are presently progged to result in a high swim risk
Saturday on beaches in Presque Isle Co. This was added to the Haz
Wx Outlook earlier today.

Temps will be sharply cooler. Mins tonight will range thru the
40s. Highs Sat in the mid 50s to mid 60s.

&&

.SHORT TERM...(Saturday night through Monday)
Issued at 336 PM EDT Fri May 29 2020

High impact weather potential: Frost potential for Saturday night
(and Sunday night?) for portions of eastern upper and northern lower
Michigan.

High pressure moves overhead of the forecast area Saturday night,
clearing any remaining clouds, producing light wind and excellent
radiational cooling. Ensemble members of the SREF and GEFS are both
tightly centered near the mean of around 32 degrees...from
experience we know that the inland areas and especially the
traditionally colder locations may reach into the upper 20s. Sunday
is supposed to be a bit warmer, so don`t expect as widespread of
frost during Sunday night (or possibly none if winds don`t
decouple), but still some areas inland of the Great Lakes coastlines
will continue to have a frost potential...will need to check again
after the next model runs. Other than the frost, skies should be
mostly clear to partly cloudy Sunday with only some minor gustiness
during the afternoon hours from the west to northwest and should at
least diminish in intensity and possibly even decouple. Winds remain
out of the west for the most part Monday (with afternoon gustiness
once again) as high pressure just begins to move to the east of us
and allow some return moisture to begin late Monday evening on the
western periphery of said high pressure...returning shower chances
to northwest lower Michigan by the end of this forecast period
(Monday afternoon/evening). There will be increased cloudiness
Monday as aforementioned deeper moisture approaches the forecast
area. High temperatures will be in the low to mid 60s Sunday and
warm into the upper 60s to low 70s Monday.

.LONG TERM...(Monday night through Friday)
Issued at 336 PM EDT Fri May 29 2020

High impact weather potential: Thunderstorms possible Monday night
through Tuesday evening.

The next chance for precipitation appears to be the beginning of
next work week when a cold front associated with a low pressure
system over Canada approaches the Great Lakes region. We once again
will be in the warm sector ahead of this cold front...with a decent
LLJ, deep moisture, and upper level wave to help with the developing
of rain showers and thunderstorms once again. Pattern becomes a bit
more zonal after this...with only nuisance clouds and showers at
different periods of the long range forecast. Daytime temperatures
should be in the 70s with some locations occassionally hitting the
80 degree mark...while lows should be in the 50s.

&&

.AVIATION...(For the 00Z TAFS through 00Z Saturday evening)
Issued at 700 PM EDT Fri May 29 2020

Secondary cold front will continue to slide thru Lower Michigan
tonight...ushering much cooler air into our state. Low clouds and
MVFR/low VFR cigs will accompany this colder air. A few showers
are also possible...but the chances are too small to include in
the TAFs for now. NW winds around 10 kts tonight will strengthen
to 10 to 20 kts with higher gusts on Saturday.

&&

.MARINE...
Issued at 336 PM EDT Fri May 29 2020

Nw winds will increase tonight into Saturday, as a secondary cold
front arrives and brings cooler air to northern MI. Small craft
advisories are already up on many waters. Lighter winds are
expected Sat night into Sun morning, before w to sw winds start to
pick up again Sun afternoon.

&&

.APX WATCHES/WARNINGS/ADVISORIES...
MI...NONE.
LH...SMALL CRAFT ADVISORY until 8 PM EDT Saturday for LHZ347-348.
SMALL CRAFT ADVISORY until 7 AM EDT Saturday for LHZ345-346.

Mesoscale Discussion 0764
NWS Storm Prediction Center Norman OK
0708 PM CDT Fri May 29 2020

Areas affected...eastern Wyoming...western Nebraska...far northeast
Colorado

Concerning...Severe potential...Watch unlikely

Valid 300008Z - 300145Z

Probability of Watch Issuance...5 percent

SUMMARY...Isolated marginally severe hail and wind are possible
across portions of eastern Wyoming into western Nebraska and far
northeast Colorado this evening.

DISCUSSION...Thunderstorms are developing this evening across the
central High Plains along the northeastern periphery of an upper
high over the Four Corners. Weak upslope flow and daytime heating
have helped initiate storms within an environment characterized by
modest instability (500 J/kg of MLCAPE) and shear (30-40 knots bulk
shear). High-based, splitting storms are likely given the relatively
straight hodographs and dry low-levels. Marginally severe hail is
possible along with damaging wind gusts. These storms are likely to
diminish shortly after sunset, and a watch issuance is unlikely
given the isolated, marginal nature of the storms.
