Detailed Summary: A front and an associated plume of moisture moving into the Northwest will produce an area of Heavy Precipitation over the Pacific Northwest and parts of Northern California on Thursday and Friday. Furthermore, as the low pressure moves inland over the Northwest, areas of Heavy Snow will develop over parts of the Bitterroot, Salman River, and Sawtooth Mountain Ranges on Thursday and Friday. Also, areas of Heavy Snow will develop over parts of the Wind River Mountains, likewise, on Thursday and Friday. Also, on Thursday, high pressure over the Northern High Plains will move to the Middle Mississippi Valley by Friday, then the Southeast by Saturday. The high will bring a cold air mass, producing an area of Much Below Normal Temperatures over parts of the Northern/Central Plains and the Upper Mississippi Valley into parts of the Upper Great Lakes on Thursday and Friday. Low temperatures will be in the low to mid-twenties below zero, with single digits extending as far south as Kansas. Gusty winds will develop over parts of the Texas Panhandle on Thursday, but the wind speed will be less than the criteria for high winds to be placed on the Hazards Chart. A wave of low pressure over the Lower Mississippi Valley will move northeastward to off the Mid-Atlantic Coast by Friday. The low will produce an area of Heavy Snow over parts of the Ohio Valley, Central Appalachians, parts of the northern Mid-Atlantic, and the Northeast on Thursday and Friday. As the low moves to the coast, strong winds will develop along the Mid-Atlantic to the Northeast Coast on Friday and Saturday. Low pressure over the Northern Plains will move northeastward to near James Bay in Canada on Saturday and Sunday. The low will produce strong winds over Lakes Superior, Michigan, and Huron on Saturday and Sunday. The associated front will move across the Plains to the Mississippi Valley on Saturday and the Lower Mississippi Valley on Sunday and off the East and Gulf Coast by Monday. The boundary will intersect moisture over the Lower Mississippi Valley and parts of the Southeast on Saturday and Sunday, producing a region of Heavy Rain from the Lower Mississippi Valley into parts of the Southern Appalachians on Saturday into Sunday. Over Alaska, an area of deep low pressure over the North Pacific will move just south of the Aleutians on Thursday and Friday, moving into the Gulf of Alaska on Saturday. The pressure gradient associated with the low will produce an area of High Winds over the Aleutians and the Alaska Peninsula, and parts of Kodiak Island on Thursday and Friday. As the low moves eastward across the Gulf of Alaska, moisture will stream into parts of the South-Central Mainland and the Panhandle producing an area of Heavy Precipitation from Kenai Peninsula to the Alaskan Panhandle on Saturday into Monday. Furthermore, as the low moves close to the Panhandle, an area of High Winds will develop along the coast from east of Valdez to the Alaska Panhandle on Saturday into Monday. Meanwhile, Two areas of Much Below Normal Temperatures will be across parts of the Alaska Peninsula into the Southwest mainland from Thursday to Sunday. However, the temperatures will moderate a bit by Monday. The second area of Much Below Normal Temperatures will be over parts of the South-Central Mainland into parts of the Interior from Thursday into Monday. Ziegenfelder
