What began as a balmy first half of the month for the eastern United States has turned into, or soon will become, the coldest weather of the season. Snow will pile up high in the Great Lakes region and strong wind will force wind chills well below zero degrees over the next couple of days. Freezes will occur as far south as the central Gulf of Mexico coast and northern Florida. * * * Cold air that built up over the western states during the last days of October and early November eventually spilled into the Great Plains, inducing the season's first blizzard in the northern Plains. A second storm of size dumped a foot of snow in Nebraska by mid-month while cold air was continuing to pool in the western and central states. The cold has now set its mind to head east and will overrun just about all of the eastern United States by Thursday morning. Frost and freeze conditions will reach south to the central Gulf of Mexico Coast Tuesday morning and will reach northern Florida Wednesday. Meanwhile, low temperatures in the Great Lakes region will slip to the single digits and teens. Some 20-degree lows may affect the eastern Great Lakes and northeastern states Tuesday, but many more teens and 20s will occur Wednesday. A strong wind is helping to push the cold air into the eastern states, but it also is inducing some impressive wind chills. Wind chill temperatures before dawn Monday slipped colder than -30 in parts of the middle Missouri River Valley. Wind chills at midday were varying from -20 to zero from Iowa into eastern Wisconsin, Minnesota and eastern North Dakota. Wind chills of -10 to 10 were occurring elsewhere across the Midwest where midday temperatures were holding in the 20s. Cool air was pouring into the southeastern states too Monday afternoon when temperatures were struggling into the 50s after being 10 to 15 degrees warmer during the weekend. Anytime a cold northwesterly wind blows across the Great Lakes region while water temperatures are mild to warm, as it has done Monday, you can expect significant snowfall downwind from the lakes. Very heavy accumulations will occur in northwestern New York state, northwestern Pennsylvania and western portions of lower Michigan. Portions of the eastern lakes area will see from 12 to 24 inches of snow by the weekend and more will occur thereafter. Light snow will fall elsewhere across the northeastern United states, but the further one travels away from the lakes the less impressive snow accumulations will become. A trace to 4 or 5 inches will occur in the northern Appalachian Mountain region and interior portions of New England as the snow continues Tuesday and early Wednesday. Tranquil weather will affect the remainder of the nation over the next couple of days. Rain will develop in coastal areas of Oregon and northern California before shifting into the southwestern desert region Tuesday and early Wednesday. By Thursday, a developing storm will have enhanced rain and mountain snowfall from the southern Rocky Mountain region into west Texas, New Mexico and southeastern Arizona. Rainfall in Oregon, California and Nevada over the next couple of days will vary from a trace to 0.60 inch with the greatest amount expected in coastal areas. No more than 0.30 inch of moisture will occur in interior areas. Temperatures will be mild in the western United States the next couple of days. Highs in the 40s and 50s will affect the Pacific Northwest while the 60s and 70s occur in the southwestern desert region. Most of the southern Plains will experience a brief one-day warm-up with highs Tuesday reaching into the 60s as far north as southwestern Kansas. Meanwhile, Georgia and most of the southeastern states will only see highs in the 40s with much colder weather north into the Great Lakes and northeastern states where highs will just be in the 20s.
