Warmth Returns Sunday To Southern Minnesota - Another Clipper Passes To The North

Strong Winds On Saturday

We saw a windy Saturday across the state, with numerous locations seeing gusts in the 40-50 mph range. Some of the strongest gusts in places occurred before sunrise. Here is a list of all the airport locations that saw a gust of 50 mph or higher on Saturday:

Rochester - 55 mph (5:56 am)
St. Paul - 52 mph (7:09 am)
Morris - 52 mph (4:31 am)
Eden Prairie - 51 mph (4:32 am)
Slayton - 51 mph (5:42 am)
Owatonna - 51 mph (5:36 am)
Alexandria - 51 mph (2:33 am)
Jackson - 51 mph (6:53 am)

Saturday Snow Amounts

It was also a snowy start to Saturday morning in some areas of the state. This was my view as I woke up in the St. Cloud area Saturday - a coating of snow on the ground, most of which had melted by midday. The Twin Cities also got in on the action, officially picking up a trace of snow Saturday. Those in St. Cloud were a little luckier, picking up 0.4" of snow.

The heaviest totals, though, were off to the north and east, with numerous 1-4" amounts common. The Duluth airport officially picked up 3.3" while the heaviest total in the state was 5.5" recorded two miles west of Leonidas in St. Louis County.

A Look At April Records 

I'm one who loves stats and climatology, so it only seems fitting that while I am filling in today that we take a look at April records for the Twin Cities, including highs, lows, precipitation and snow.

Since it has been cool the past couple days, I thought I would start off with April record highs. Most of the record highs fall within the 80-degree range, with seven days of April seeing a record high in the 90s. The "easiest" record to break during the month would be that one day in the 70-degree range - a relatively cool 78 set back on the 2nd of 1981.

When looking at when the record highs were set, only one has occurred within the 2010s - the 84 degree day back on April Fools Day last year. Only five of the current record highs on record occurred before 1950 - two in the 1920s and three in the 1930s.

Turning our attention to record lows, the good news is that we are out of the subzero lows range - all of the April record lows are at/above zero. The coldest April night we've ever had on record was 2, back on the 13th of 1962.

The wettest April day ever was back on the 6th of 2006 when 2.58" was recorded. Most of the records fall within the 0.50" to 1.75" range.

Even though we are moving toward the warmer months of the year, we can still see a wide range of snow during the month of April. The easiest snow record to break is 0.4" of snow, set on the 24th of 1887. The heaviest one day snow was back in 1983, when 13.6" fell on the 14th.

Ice out dates so far this spring. Image: Minnesota DNR.
Continued Early Ice Out Dates. We continue to see lakes losing ice across the state, in many cases earlier than average. According to climatologist Mark Seeley in his weekly WeatherTalk blog, "In many cases lakes are losing their ice 2 to 3 weeks earlier than average. For example Pearl Lake in Stearns County lost ice on March 15th (reported by Sue Dudding) and this is the earliest of record, while Lake George in Anoka County also lost ice cover on March 15th, a record early date. Average ice-out date on Pearl Lake occurs on April 4th and on Lake George it is April 6th."

Like Flicking on a Light-Switch: Instant Spring
By Paul Douglas

Major takeaways from the Severe Storm & Doppler Conference in Des Moines: the new NWS dual-polarization Doppler upgrade is so sensitive it can pick up a TDS, a "Tornado Debris Signature". A major tornado can loft debris 4-5 MILES into the sky. Tracking debris increases confidence that a tornado is, in fact, on the ground.

And suburban sprawl has increased the potential for tornado disasters. America's population has doubled in the last 80 years. More suburbs, more subdivisions, increase the likelihood that if a tornado DOES touch down there will be damage and injury. We are inadvertently standing up more pins in lane 3 of the neighborhood bowling alley.

After Saturday's blustery winds today should be a breath of fresh air with 50s, even a shot at 60F. Canada isn't done roughing us up: expect a family of clippers this week; each one dragging cool exhaust south of the border.

The best chance of rain comes Tuesday - by late week temperatures recover into the 50s. A reminder that spring is more theory than reality.

By mid-April we should see consistent 50s and 60s. In theory.

Sunday Minnesota Weather Outlook

We will be a state divided Sunday... Divided by temperature, that is. Highs across southern Minnesota, squarely placed in a warm sector, will make it into the 50s and 60s. There's even the chance some locations in southwest Minnesota could make it into the low 70s. On the other half of the dividing line, highs will only be in the 30s across northern Minnesota.

On the heels of the clipper that brought snow to northern Minnesota Saturday, another will be moving through Sunday bringing the potential of another 1-3" of snow to the region. Skies will be partly sunny across southern Minnesota.

Here's a look at the snowfall forecast through Monday at 7 AM - again, it looks like 1-3" across parts of northern Minnesota, with potentially some isolated 4-5" amounts.

Due to that next batch of snow coming Sunday, Winter Weather Advisories have been put in place for parts of the Arrowhead.

National Outlook

The clipper that affected northern Minnesota Saturday will continue east Sunday, bringing Buffalo and Rochester, NY the potential of 3-6" of snow. It will also continue to bring windy weather with it, with the potential of 50-60 mph wind gusts from Baltimore to Philadelphia, New York City and Boston. Moisture will be moving off the Pacific as we head into the beginning of the work week, bringing parts of the Pacific Northwest rain. That moisture will travel east and bring us the chance of rain as we head toward the middle of the week.

Thanks for checking in and have a great Sunday! Don't forget you can follow me on Twitter (@dkayserwx) or on Facebook (Meteorologist D.J. Kayser)!
