Low pressure over the Great Lakes and high pressure over Central Canada will produce a strong
pressure gradient across the Great Lakes on Thursday. Therefore, an area of High Winds will be over
Lakes Superior, Michigan, and most of Lake Huron. The High Winds will also impact the adjacent land
areas on Thursday and Friday. The low-level wind will be up to 40 mph over the open waters.
Furthermore, high pressure over Central Canada will move southward on Thursday and Friday, settling
over the Middle Mississippi Valley on Saturday, then moving into the Ohio Valley on Sunday. The
high pressure will bring clear skies and calm winds, allowing temperatures to become 32 F or lower,
promoting frost over the region. Therefore, on Saturday and Sunday, an area of Much Below Normal
Temperatures over parts of the Central Plains, Middle Mississippi Valley, and Ohio Valley.
. . .Alaska. . .
Deep low pressure over the Chukchi Sea on Thursday will move into the Arctic Ocean on Friday. The
associated pressure gradient will produce an area of High Winds over the West Coast of the Mainland
into the Northwest Coast of the Far North and the Bering Strait on Thursday and Friday. The storm
will also produce 0.50 to 0.75 inches of rain along the western Brooks Range and 0.50 inches over
the Kuskwim Mountains on Thursday. The associated front will produce Heavy Precipitation over parts
of the Alaska Range into parts of the Aleutian Range on Thursday, with the greatest areal coverage
on Friday. On Saturday, the Heavy Precipitation will begin to taper off and go below the criteria
for Heavy Precipitation on Sunday. However, the Heavy Precipitation will impact Denali National
Park's area from Thursday to Saturday.
Moreover, the circulation around the deep low over the Gulf of Alaska will become elongated on
Thursday into Friday, allowing moisture to flow off the gulf into South-Central Mainland. As a
result, an area of Heavy Precipitation will develop over parts of the Kenai Peninsula eastward to
near Sitka from Friday through Monday.
