Heavy snow, blizzard conditions, and flooding rainfall likely this weekend as powerful storm impacts the middle of the country
Threats: Heavy snow, blizzard, flash flooding
States affected: CO, WY, NM, NE, SD, KS, OK, TX, AR, MO, IL, IA, IN
When: Thursday, March 10 - Monday, March 15
A slow-moving, multi-hazard storm will develop late this week, bringing heavy snow to the Central Rockies and Central High Plains, as well as flooding rainfall from the Plains through the Ohio Valley.
Snow will begin Thursday evening across the Rockies, expanding eastward into the Central High Plains by Friday morning. The heaviest accumulations of 1-2 feet will occur with rates up to 2"/hr across the eastern slopes of the Central Rockies. Snow of 2-3 feet with rates to 3"/hr will occur across the Front Range.
The potential exists for even higher amounts of snow, in the 3-6 foot range, should the storm take a slightly more southern track and allow the highest peaks of the Rockies to be on the receiving end of upslope moisture.
The greatest disruption to travel and transportation will be on Saturday into Saturday night when the snowfall rates are heaviest and high winds create blizzard conditions across a large portion of the High Plains.
Multiple rounds of flooding rainfall are expected from Thursday evening into the weekend, with rainfall rates reaching 2”/hour at times. The potential for widespread flooding exists from northeastern Oklahoma into southeastern Kansas and southern Missouri, as abnormally high rainfall rates will occur over still dormant vegetation.
With flooding occurrences becoming more frequent as we head into spring, now is the time for businesses to review their assets in relation to flood zones and ensure flood safety is a part of their emergency action plan.
AccuWeather For Business will provide site-specific warnings to clients during this period for varying rainfall amounts and rates that are determined based on geographical location, flood frequency, and site design and material.
