Severe Thunderstorm Warning 40, NWS Marquette, MI

Area Forecast Discussion
National Weather Service Marquette MI
234 PM EDT Sun Jul 1 2018

.SHORT TERM...(This evening through Monday)
Issued at 234 PM EDT SUN JUL 1 2018

Upper air pattern consists of a 500 mb 500 mb ridge in the ern U.S.
with a trough across the central and northern plains. There is a
shortwave moving through the trough that will be affecting the upper
Great Lakes this afternoon into this evening and this moves into
Canada on Mon. The pcpn will move out this evening over most of the
cwa with drier air moving in late tonight, then quiet weather for
Mon. It will be less humid on Mon as well.

.LONG TERM...(Monday night through Sunday)
Issued at 234 PM EDT SUN JUL 1 2018

No changes from the previous forecast. Weather of significance in
the long term is heat and humidity into Thu, then possibly some
stronger convection around the Thu time frame.

Upper ridging and southern low level flow will continue the heat and
humidity. Tue through Thu will see highs in the 80s to around 90
with dew points in the 60s to around 70. This should result in heat
indices from the mid 80s to mid 90s.

Models continue to show a shortwave rolling across Canada, dropping
a cold front through the area generally in the Thursday time frame.
Depending on timing and numerous other details, this could result in
stronger convection, but at least scattered general convection
regardless.

Otherwise, more seasonable temperatures can be expected for Friday
through next weekend. Dry high pressure is expected to dominate this
time period, so any rain chances will be minimal at best. No major
changes were needed from the model consensus.

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 121 PM EDT SUN JUL 1 2018
A frontal boundary moving through Upper Michigan this afternoon into
the evening will bring another round of showers and thunderstorms
into the area. Brief periods of very gusty winds and some hail may
develop with the stronger storms at SAW. However, the timing and
location of the impacts remain uncertain. MVFR cigs are expected
with the areas of rain with the potential for some IFR conditions
over the west into this evening. Drier air moving in behind the
front will bring improvement to VFR overnight.
&&

.MARINE...(For the 4 PM Lake Superior forecast issuance)
Issued at 234 PM EDT SUN JUL 1 2018

The very warm, humid air sliding over the relatively cool waters of
Lake Superior, will support widespread fog through Mon morning. The
fog could become locally dense where rainfall occurs. Winds should
remain below 20 knots into the middle of the week.
