Snow On Ground Today, Gone by Saturday(??)
April Storm Biggest of Cold Season
Yesterday's snow storm ended up being St. Cloud's biggest of the cold season. 8.5 inches were recorded at the St. Cloud Prison, beating the 8.2 inches on February 20 and 21. Not only did this storm blow away the April 16 snowfall record of 3.0 inches set in 1961; yesterday's snowfall alone would rank as the 10th snowiest April on record. The actual April snowfall total is now 12.0 inches, which ranks as the 4th snowiest April on record. The total seasonal snowfall in St. Cloud has jumped to 75.5 inches, tying 1916-1917 for 5th place and only 3 inches short of last cold season's ridiculous 78.5 inches.
Yesterday was St. Cloud's 48th day with measurable snowfall. That ties 1974-1975 for 9th most. The record total was 60 days in 1950-1951. There were 49 days in both 1993-1994 and 2012-2013. And, this morning will be St. Cloud's 128th day of the snow season with at least an inch on the ground. If we hold on to the snow through Saturday, it would only be the 17th time there have been at least 130 days with an inch of snow on the ground during the cold season.
Who Got the Most?
The heaviest snow fell in a swath from Redwood Falls to Wright and Meeker Counties, Big Lake, Cambridge, Isanti and Pine City. The highest totals included North Branch 15.1 inches, Darwin 14.8 inches, Monticello 14.6 inches, Big Lake and Milaca 14.5 inches, 14 inches in Litchfield and St. Francis, Maple Lake 13.5 inches, 13 inches in Stacy and Sheldon, 12.7 inches in Rogers, and 12 inches in Hillman and Mora. Some places with high snowfall, like Annandale (10.0 inches) had their last report before the snow ended, so their total could be higher.
The snow is just departing the Twin Cities and the I-35 corridor as of 2 AM (see NWS
Upper Mississippi Valley radar loop) as the storm pushes through Wisconsin and into Upper Michigan (see infrared loop from College
of DuPage Satellite and Radar Menu). Clearing skies have now moved into central Minnesota (see Colorado State RAMDIS western fog/reflectivity product). Still, the rapid rate of snow accumulation means that road crews have some catching up to do. Expect slow improvement of conditions on the MnDOT road conditions site.
Also note that this is a very wet snow that is heavy, so be careful if you are shoveling.
Spring: Wait For It...
Among all of the questions I received yesterday, "When will the snow melt?" was common. We will get a slow start to the melting today as highs will struggle to get much beyond 40 degrees. It will remain colder than average, although not quite as cold as earlier in the week, through tomorrow. There are a couple of "next" storm systems with the biggest one coming onshore in British Columbia (see infrared loop from College
of DuPage Satellite and Radar Menu). A weaker storm, however, is producing some clouds in the Canadian Rockies. This system will push southeastward and move into Minnesota tonight into early tomorrow. It looks like this storm will have slightly more moisture than had been thought earlier, so look for clouds tonight through tomorrow morning. We might have a chance of a stray snow(?!) FLURRY!!!!! late tonight or early tomorrow, but it won't amount to anything. Those occasional flurries will become sprinkles tomorrow afternoon. Again, temperatures will top out in the 40's, but the clouds will keep low temperatures tonight in the 20's.
The weak system coming through tonight is the next attempt to pump warmer air into Minnesota. However, that British Columbia storm will do a better job once it pushes into the Plains on Saturday (see NWS HPC Short-Range forecast map). This will also produce a better chance of RAIN!!! showers or even a thunderstorm late Friday night through the first part of Saturday. The persistent clouds should keep temperatures Friday night in the 35-40 range, so I'm not worried about spotty freezing rain in the area. Even though Saturday will have a lot of clouds, the warmer air will move in behind the morning storms, so highs will climb into the upper 50's and perhaps even the lower 60's. That should mark the end of the snow cover.
The warm front will be past us for Sunday and Monday, so look for spring to finally resume Sunday with the warmth continuing through much of next week. On Sunday, high temperatures will climb to the upper 60's to lower 70's with 70's likely on Monday. Slightly cooler air will move on Tuesday with highs in the upper 60's. However, another warm front is slated to push through late Tuesday night and early Wednesday. I'm getting bold by forecasting that far in advance, but it looks like more 70's on Wednesday.
Another Common Question from Yesterday..
No, that doesn't necessarily mean we're done with snow this cold season (it doesn't mean that there will be more snowstorms either). We just can't see that far into the future reliably.
I now pause for more yelling and screaming.......and ducking projectiles while shoveling..
