This is a look at the 48hr snowfall potential across the eastern half of the country. Note the fairly narrow, but heavy snow bands across parts of the Midwest and South/Southeastern part of the country.
Precipitation Outlook Next 3 Days
According to NOAA’s HPC, the 3 day precipitation outlook captures the individual storm systems fairly well. Note the band of precipitation over the South/Southeastern part of the country and again over parts of the Midwest. However, the Western U.S. also looks fairly soggy, which is interesting because a series of storms from the Pacific Ocean and western half of the country will keep things rather active across the eastern half of the country late this week/weekend and early next week.
Soggy End of February/Early March
As you may or may not know, the first day of Meteorological Spring is this Sunday (March 1st). According to NOAA’s HPC, the 7 day precipitation outlook shows some pretty significant moisture through the middle of next week. Some models are even projecting a fairly thundery outlook across parts of the Lower Mississippi/Tennessee Valley and Gulf Coast States… Stay tuned for more on that. However, it appears that March could roar in like a lion!
