Snow, Heavy At Times, Through 6-7 PM (Updated for SCSU Snow Depth)
So far, this storm has lived up to expectations (or produced great disappointment for those who would wish it away). The snow began in earnest in central Minnesota around 10-11 AM . As of 5 PM, I measured 7.2 inches of snow at SCSU, so the snowfall rate has been around an inch an hour through midday and afternoon along the main snowband (see NWS
Upper Mississippi Valley radar loop). At 4:30 PM, the St. Cloud Prison also had 7.2 inches. This breaks the April 16 snowfall record of 3.0 inches set in 1961. In fact, today's total alone would rank 10th among the 10 snowiest Aprils in St. Cloud.
Not all of the area of radar echoes is seeing snow sticking, but where temperatures are at or below freezing, generally from Fergus Falls through Staples, Brainerd and Grand Rapids on the north side and from Cambridge though Buffalo, Crystal, Benson, and Appleton on the south side, it has continued to accumulate all day (see UCAR
Minnesota surface chart loop).
Snowfall reports include 13 inches in Onamia, 12 inches in Little Falls, 9 inches in Cambridge, 8.8 inches in Princeton, 7 inches in Annandale and Isanti, 5.5 inches in Milaca, 5.1 inches in Randall, 5 inches in Long Prairie, 4 inches in Zimmerman, 3.6 inches in Monticello among reports at noon or later.
The western edge of the snowband has been approaching the Minnesota-South Dakota border and will push eastward during the rest of the afternoon. So, the snow should let up substantially in the St. Cloud area by 6 PM, but that's another 4 hours of an inch/hour snowfall. Unfortunately, despite all the begging, pleading and threatening, we will generally end up with 6-10 inches in the main snow band with places between St. Cloud and the Twin Cities possibly getting a foot of snow.
Road conditions have been difficult along this snow band as seen on the MnDOT road conditions site with a steady stream of accidents reported along all major roadways. Those will likely continue past the time that the snow tapers off since it will take a while for road crews to catch up with this heavy snowfall rate.
In the Twin Cities, the snow has only been sticking in the northern and western suburbs and the heaviest precipitation in the next 3 hours will still likely melt on contact with the ground. However, temperatures will begin to fall later this afternoon, so the snow could begin sticking by 5-6 PM. This would still allow 2-4 inches to accumulate with ice hiding underneath in some areas of the Twin Cities.
Cold Continues Late Week
After this storm goes by, another round of cold air will push in for Thursday and Friday. The snow will end by mid-evening, then we will be breezy and colder, with temperatures bottoming out around 20 degrees. That should be a few degrees milder than any record cold lows. Highs, however, will stay in the middle to upper 30's.
We will have a lot of clouds on Thursday night as a weak upper-level storm moves by. The air near the ground will likely be too cold to produce any precipitation, but clouds should keep low temperatures in the 20's, not the teens. It will be a little milder on Friday with highs in the lower 40's.
Warmer Air Begins to Move in After Saturday Cold Rain
Our next storm system will push across Minnesota on Saturday. This system will start pumping much warmer air into the Northern Plains Friday night. The key will be how cold the ground gets when the precipitation begins in the early morning hours on Saturday. Right now, it looks warm enough aloft for rain to develop, but some places nearby could have ground temperatures of freezing or a degree or two below. So, there is a threat of some freezing rain early Saturday morning, but it's too early to pin down where.
Ground temperatures should rise with the southeast winds and daybreak on Saturday, so any freezing rain will quickly change over to rain. The rain should taper off by midday. There will be a lot of afternoon clouds, but we could have some sunny periods. That should allow temperatures to finally climb to the more seasonable lower 50's. The combination of having most of Friday night above freezing, getting some rain on Saturday, and having temperatures climb into the 50's should mean the end of the snow that has fallen today by late Saturday or Saturday night.
The one computer forecast that was holding out on breaking into some more spring-y temperatures has finally caved, so I feel free to forecast highs in the 60's on Sunday and in the 70's on Monday. We certainly will have suffered enough cold this week to bask in some warmth. And, I generally see a warm weather pattern through the middle of next week. So, there is no return to this cold (or snow) in sight.
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 Don't Want to Hear More About Snowfall Records
With today's snowfall, we've "achieved" 48 days 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.
Through 4:30 PM, the 2013-2014 cold season snowfall in St. Cloud has topped 70 inches again with 74.2 inches. That gets us to 6th highest total and we will likely push near or ahead of 1916-1917 by the end of the day. The next year up is last year with 78.5 inches. That 7.2 inches has pushed the April total snowfall to 10.7 inches.We will likely have 11-12 inches for the month by the end of this storm, pushing us into the top 5.
Tomorrow will be our 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.
I now pause for more yelling and screaming.......and ducking projectiles......
