GFS/Tropical Tidbits
February 11, 2021
❄❄❄❄ Two High Impact Winter Storms will affect the Southern Plains, Tennesee and Ohio Valleys, along with parts of the Northeast next week. Disruptions to travel are expected as heavy snow, combined with very cold temperatures, blanket areas hard hit by recent storms...
Storm #1 will get organized early Sunday across the southern Plains and will plague residents from east Texas to the central Tennessee Valley. As the day progresses, Gulf of Mexico moisture will run into a deep, Arctic air mass, setting the stage for heavy snowfall. The peak of this storm appears to be mid-morning Monday through early Tuesday for the northern Tennessee Valley, and most of the Ohio Valley. Significant snowfall accumulation is likely for most areas. Modest wind and cold temperatures will add to the impact from this storm.

*Total Snowfall(10:1) Sunday 7pm through Tuesday 1pm

As noted in the graphic, Storm #1 will overspread the area late Sunday into Monday. Specifics are not yet ready to be discussed, so we will show the European at 10:1 ratios. Significant snowfall can be expected. With Arctic air in place, it is likely snowfall ratios will be higher. Fine tuning will come over the next day or two. This sets the stage for Storm #2.

ECMWF/Pivotal
February 11, 2021
If that was not enough, 36-48 hours later, another significant storm will track almost in Storm #1's path. The timing on this storm will be from middle Wednesday through early Friday, next week. We have to wait for the first storm to exit, because some changes will occur. However, with deep-rooted Arctic air in place and fresh snowpack on the ground, another significant frozen storm is likely. This will bring another round of hefty snowfall. As you can see, at 10:1 ratios, both storms will likely bring over a foot of snow. If ratios end up being higher, snow totals will end up being higher than advertised. Check back often for future updates.
