Detailed Summary:

. . . CONUS . . .

On Monday, cold high pressure over the Northern/Central Plains will move eastward to the Ohio
Valley by Wednesday. The cold air associated with the high pressure will produce an area of Much
Below Normal Temperatures from interior parts of the Pacific Northwest to the Northern/Central High
Plains and Central Plains from Monday through Wednesday. In addition, a second area of Much Below
Normal Temperatures will develop over the Northern/Central Plains eastward to parts of the Upper
Great Lakes and Western Ohio Valley from Monday to Thursday. Low temperatures will range from 20
below zero to the upper signal digits below zero and high temperatures ranging from the upper
signal digits to the lower twenties over parts of the Northern Rockies and Northern Intermountain
Region. Over the eastern section, low temperatures from 20 below zero to the low teens and high
temperatures from signal digits below zero to the low twenties over parts of the Northern Plains to
Middle Mississippi Valley. On Friday, the temperatures will moderate over the eastern parts and on
Thursday, over the western half.

Meanwhile, low pressure over the Central Rockies will aid in producing an area of Heavy Snow over
parts of the Southwest and Central Rockies on Monday. Furthermore, on Monday, another area of low
pressure over the Lower Mississippi Valley will move to the southern Mid-Atlantic by Tuesday. The
system will produce an area of Heavy Precipitation over parts of the Lower Mississippi Valley to
the Southern Ohio Valley, which will be on the north side of the low, producing areas of snow,
rain, and sleet on Tuesday.

Moreover, a front over the Central Gulf Coast on Wednesday will have moisture from the Gulf of
Mexico will stream northward over the front producing an area of Heavy Rain from parts of the
Southern Plains to the Tennessee Valley/Southern Appalachians.

. . .Alaska. . .

Upper-level ridging over Alaska will start to weaken as upper-level energy moves eastward from the
Bering Sea over the Mainland. However, on Monday, the upper-level ridging will aid in producing an
area of Much Above Normal Temperatures over the Southwestern Mainland. Temperatures will be just
above freezing over the region on Monday, with only a few locations around 34 degrees F and
decreasing on Tuesday.

Low pressure just south of the Alaska Peninsula on Monday will move into the Gulf of Alaska on
Tuesday and Wednesday. On Thursday, the associated front will move into parts of the Panhandle. The
system will produce rain and snow over parts of the Alaska Peninsula on Monday and parts of Kodiak
Island on Tuesday. The precipitation will be below the criteria for hazards. On Wednesday, rain and
snow will start to move over the southern part of the Panhandle and then over the whole Panhandle
on Thursday. However, again, the precipitation will be below the criteria for hazards. Light snow
will develop over parts of the Interior and Far North on Monday and Tuesday. The weather will be
mainly dry over other parts of the state on Thursday and Friday.
