Definition of a “slop storm:”
Take one part rain, two parts heavy wet snow, and throw in temps above freezeng and warm ground underneath and what do you get?
A world class slop storm.
Temps just above freezing meant a mix of rain and heavy wet snow that downed some branches in northwest Minnesota & the Red River Valley Thursday.
The good news?
A big swath of 1″+ rainfall & sloppy snow made for a pretty effective “fire extinguisher” in northwest Minnesota Thursday. The “peat bog” originated fires that burn in the ground are not out…but at least the landscape is wet. Talk about effective (if temporary) fire suppression.
