It’s certainly been a miserable, yet interesting day so far as far as our local weather goes. We started the day with a round of thunderstorms just aftermidnight that rumbled through the Rochester area at about 2:30, producing pea sized hail and heavy rainfall. We picked up about 0.30 inches in northwest Rochester in that hour long shower and the landscape was thoroughly covered in small hail. Some people in Rochester reported almost an inch of hail covering their yards before dawn from this event.
A second round of enhanced precipitation, possibly involving elevated thunderstorms, came through the area at about 8:30 am, and dropped anouht quarter of an inch ofrain and produced some small hail as well as some sleet, or ice pellets. It’s a little difficult to say exactly if it was one or the other or both as surface temperatures cooled to 34 degrees during that round of moderate precipitation and temperatures aloft were close to freezing as well. It’s possible that hail formed along a line of weak thunderstorms and then as the air became dynamically cooled, sleet followed.
We’ll have some more showers in the area today and this evening with a chance for some thunderstorms, some possibly producing soem small hail at times. There will be an even better chance for some sleet mixing with that rain late tonight and tomorrow as colder air filters into the area behind this storm system as it moves to the east. A little snow is expected tomorrow as well. This is definitely quintessential March weather for southeastern Minnesota!
