Duluth and surrounding areas of northeast Minnesota are now under the gun for some hefty snowfall totals as a strong May storm system rapidly grows cold, resulting in rain changing over to snow Wednesday night through Thursday morning.
With that, the National Weather Service has issued a winter storm warning for Carlton, Lake, Cook and southern St. Louis counties from 7 p.m. Wednesday through 10 a.m. Thursday. The warning includes the cities of Two Harbors, Duluth, Grand Marais, Superior and Silver Bay, among others.
Upwards of a half a foot of snow could fall, according to the NWS:
"Total snow accumulations of 4 to 8 inches, except 6 to 10 inches along the higher terrain surrounding Lake Superior."
These predicted snow totals are nearly double what the early Wednesday morning forecast from the NWS Duluth called for, so this storm is not messing around.
Here's the simulated future radar (may not work in all browsers) from 3 p.m. Wednesday through 8 a.m. Thursday.
Minor accumulations are possible southwest of the Duluth area as Brainerd, St. Cloud and even further towards the higher elevations along the Buffalo Ridge in southwest Minnesota could get snow.
The National Weather Service isn't suggesting anything more than a dusting to an inch or two for those areas, but the HRRR model, among other models, have suggested decent snow totals beyond the winter storm warning. We'll see who's right...
