The coastal storm that produced measurable snowfall from the Mid-Atlantic to the Northeast is racing northeast and high pressure is building in behind it. Below normal temperatures return to the Northeast on Monday with high temperatures struggling to get above freezing. While the Northeast struggles to crack the freezing mark on Monday, parts of the Northern Plains will struggle to get above zero as a prolonged bout with frigid temperatures continue into the middle of the week. Brutal wind chills as cold as -50 degrees also linger in portions of the Northern Plains and Upper Midwest through Tuesday. Due to the dangerously cold conditions, Wind Chill Warnings and Advisories have been issued for many of these locations through the first half of the week. The surge of below normal temperatures advances into the South-Central U.S. on Tuesday. While this cold is quite anomalous, only a handful of daily low max/min temperature records are forecast to fall over the next few days. The first half of the week features several different areas of wintry weather. Starting in the Northwest, more snowfall is expected tonight and into Monday over the northern and central Rockies. The heaviest totals are forecast to occur in the Bitterroots with snowfall as much as a foot possible. In addition, Avalanche Warnings remain in place for some areas of the northern and central Rockies. Meanwhile, a frontal boundary over the south-central Plains is the focus of freezing rain over parts of northern Oklahoma tonight. Winter Weather Advisories have been issued due to the potential for icy conditions, as well as light snowfall this evening over eastern Nebraska and southwest Iowa. By Monday, snow showers head into the Midwest where light accumulations are possible. A developing area of low pressure then tracks through the lower Great Lakes Monday night and into the Northeast by Tuesday. This will leave a swath of light snow accumulations in these area with amounts as high as 6 inches possible in parts of the interior Northeast on Tuesday. Across the South, above normal temperatures are anticipated in the Southwest and along the Gulf Coast. A stalled frontal boundary over South Florida will act to ignite some spotty showers and thunderstorms on Monday. This front will then move north of out of the Gulf of Mexico and become the trigger for scattered showers and thunderstorms Monday night and into Tuesday along the Gulf Coast. The area that may receive the heaviest rainfall totals would be from eastern Louisiana to the Florida Panhandle on Tuesday. Conversely, dry and mild conditions persist into the middle of the work-week throughout the Southwest. Mullinax Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
