Detailed Summary:

Cold high pressure moving southward out of Western Canada will produce low temperatures in the low 
twenties below zero with highs in the single digits below zero over the Upper Midwest on Monday and 
Tuesday.  Therefore, the Hazards Chat will have an area of Much Below Normal Temperatures from the 
Northern Plains to the Great Lakes.  Wednesday, the high moves across the Great Lakes/Ohio Valley 
into the Northeast.  Low temperatures will be below zero in the low to mid-twenties over Northern 
Maine and with single digits into the northern Mid-Atlantic on Wednesday.  Also, the high 
temperatures will be in the single digits below zero.  Therefore, an area of Much Below Normal 
Temperatures is on the Hazards Chart for Tuesday and Wednesday.  Low pressure lingering across the 
Great Lakes and the area of high pressure moving eastward will produce strong winds across the 
Great Lakes and Northern High Plains on Monday into Wednesday.  However, the wind speed will not 
meet the criteria for an area of High Winds for the Hazards Chart.

Meanwhile, moisture plume will clip the northwestern portions of Washington State from Tuesday into 
Thursday.  Heavy Rain will develop over parts of the Olympic Peninsula and northernmost parts of 
the Cascades from Tuesday into Thursday.

A front will move across the Southern Plains into the Lower Mississippi Valley on Thursday and 
Friday.  Moisture from the Western Gulf of Mexico will stream northward, crossing the boundary 
producing an area of Heavy Rain over parts of the Southern Plains on Thursday that will expand into 
parts of the Lower Mississippi and Tennessee Valleys on Friday.  There is uncertainty with how 
large the area of Heavy Rain will be.  However, a slightly larger area is depicted on the Hazards 
Chart to cover some of this uncertainty.

Over Alaska, an area of low pressure over the Gulf of Alaska and a second low farther south over 
the Gulf of Alaska will aid in streaming moisture into Kodiak Island eastward to the Alaskan 
Panhandle, producing an area of Heavy Precipitation over the region on Monday and Tuesday.  There 
will be a brief break in the precipitation on Wednesday.

On Thursday, an area of deep low pressure south of the Aleutians over the North Pacific will 
produce an area of High Winds over the Western Gulf of Alaska and the adjacent Alaska Peninsula.  A 
second area of low pressure over British Columbia/Alaskan Panhandle will stream moisture into the 
Alaskan Panhandle, producing a new round of Heavy Precipitation from the panhandle to Kodiak Island 
on Thursday.  On Friday, the deep low from the North Pacific will move into the Western Gulf of 
Alaska, streaming additional moisture into the panhandle.

Therefore, an area of Heavy Precipitation is on the Hazards Chart on Friday as well from the 
panhandle to Kodiak Island.  The systems will raise the snow levels/freezing levels allowing rain 
to fall on snow over the region.  The snowmelt and rain could produce localized areas of flooding.
