Forecast Winter Weather Hazards An intense cold snap across the eastern two-thirds of the United States will set the stage foran impactful winter storm this weekend through Monday. Arctic air and sub-zerotemperatures will be present across the upper Midwest and Northeast on Friday and An influx of subtropical moisture into the Southwest US on Friday will clash against theentrenched cold air and lead to the development of a low-pressure system over Texas thatwill begin to move east-northeast. A large region of winter precipitation will blossom along the Saturday will bring heavy snow to regions north of the temperature boundary, with Kansas,northern Oklahoma, northern Arkansas, southern Missouri, and the western Ohio RiverValley currently forecasted to have the highest totals. South of the band of snow, warmsubtropical air is expected to advance northward while being undercut by stubborn low-level The snow and ice threat will move northeastward through Sunday, with heavy snowoverspreading Appalachia, the Mid-Atlantic, and the Northeast, including the I-95 corridorfrom Washington, D.C., to Boston. There remains some uncertainty regarding how far northimpactful precipitation pushes, leading to lower confidence in heavy snowfall over NewEngland, given current forecast guidance. At the same time, the focus of icing will move into It is notable that all weather models have shifted the overall storm track northward in recentdays, and it is possible that these trends continue with coming forecast cycles. A continuationof this north trend would ease icing impacts across the south, while increasing snowfall totalsacross the Northeast, most notably in the New York City and Boston Metropolitan areas.

Expected Impacts With extreme winter weather conditions expected from New Mexico all the way through NewEngland, current media estimates place 180 million people in the storm’s path. Widespreadflight delays and cancellations are expected across the country this weekend, with special Current forecast models estimate a potentially crippling 12-18 inches of snowfall in localizedareas, stretching from the Southern Plains through the lower Great-Lakes, Mid-Atlantic, andNortheast. It is currently difficult to pinpoint exactly where the transition from snow to freezingrain will take place but freezing rain accumulations of 0.25 inches are likely over widespread In addition to the severe winter precipitation, a dangerously cold air mass behind and north ofthis system will see temperatures 20-30 degrees below average, stretching as far south asDallas-Fort Worth in Texas. Wind chills are expected to drop to -50°F in some portions of theUpper Midwest and Northern Plains, and the southern plains and southeast could see below-freezing daytime temperatures persist until early next week.

Notable Winter Weather in the Last 5 Years Recent US winter storm experience shows that the most consequential losses are drivenless by snowfall or wind and more by extreme cold interacting with infrastructure andexposure vulnerability. The clearest example is the prolonged Arctic cold outbreak from February 2021 (unofficiallynamed “Uri” by the Weather Channel). Exceptionally cold air impacted Texas and the south- Prolonged power outages led to widespread loss of heat, resulting in extensive pipe-burstand water damage across residential, commercial, and multifamily properties. Economiclosses from this winter system are widely estimated in the USD 80-130 billion range, placingit among the costliest natural disasters in US history, while trended insured losses have anestimated range of USD 12-15 billion, reflecting both the severity of property damage and February 2021 cold air outbreak, showing the number of hours below 0°F.

A second, more recent analogue is the widespread freeze event from late December 2022(unofficially named “Elliott” by the Weather Channel), which struck much of the central,eastern, and southeastern United States in late
