Today's Weather Summary for Northeast Minnesota and Northwest Wisconsin

Well, it sure wasn't as sunny as I thought it would be Today, and we even had some surprise snow showers and flurries scattered about in parts of Northeast Minnesota and Northwest Wisconsin, other than that the temperature part of the forecast verified quite well with daytime highs in the 30s.  Winds were light and from the east around the head of Lake Superior with northwest winds elsewhere.

Party time? High temps trend toward AVERAGE mid-late week; Slap in the face early next week (Colder again) Storm 1st week of April?

*Trouble may be brewing as we head through next week.  Image below is from the 12z GFS model and is valid for NEXT Wednesday, April 3, 2013.  This is the QPF or precipitation forecast and the amounts this model shows are quite impressive.  Yellow and reds are anywhere from 0.50-1.00".  At the moment it looks like the precipitation would fall mostly as rain which would be very bad news since there's still a ton of snow on the ground so any rain on top of the snow pack would just run off.  Note:  No need to panic just yet, the models aren't in the best of agreement for next week so this system could very well disappear in future model runs.

*This next image is the 12z ECMWF (European model)  It's also valid for NEXT Wednesday AM April 3, 2013.  It also shows a weather system, but this model has 2 separate lows, one NW in Western Canada and the other over the Central Plains, so it's a little bit different than the 12z GFS…

A quiet weather week ahead; Warmest temps of the month (40s later this week?) Stormier weather 1st week of April?

Short Term, Extended, and Long Range Forecast - Confidence:  High.

(Tonight, March 23rd through April 2nd)

A relatively quiet weather pattern rolls on throughout the Northland.  No major storms in sight.  A few snow flurries can't be ruled out Tonight and Sunday, but no accumulations are expected.  Might begin to see the pattern shift on or a little after April…

A good weekend to enjoy the deep snow pack, don't forget the sunscreen.

-Minnesota snow depth map as of March 21, 2013.  (Source, MNDNR)

Still lots of snow on the ground across most of the Gopher state.  Duluth has about 18-20" on the ground.  Bigfork has close to 30".  International Falls has about 24".  Locations along the North Shore of Lake Superior have snow depths of 18-30".

-Here's the snow depth ranking map for March 21, 2013.  (Source, MNDNR)

Yes, it's quite unusual to have this much snow on the ground in late March.  For example, the map above has Duluth with 18" of snow on the ground, looking at the snow depth ranking map you find Duluth sits in the 80-95 percentile range, meaning there's only been 5 to 20 other March 21 snow depths that were greater than or equal to 18".  Note:  This is based on 100 years of weather records.

*Here's the 6-10 day temperature outlook valid for March 26-30, 2013.  Incredibly high odds for below normal temperatures in much of the Central/Eastern U.S.  (Source, Climate Prediction Center)

Note:  March 2013 has made it into the top 10 for snowiest March's at Duluth, Minnesota.  As of the 19th, the monthly snowfall total was at 25.5" which ties with 2007 for 10th place.  I don't see many opportunities for snow through the rest of the month, so it looks like will remain tied in the number 10 spot.

Weather Tidbits for Duluth, Minnesota:

-Thru March 19th, the average monthly temperature was at 18.5F which is 5.1 degrees colder than normal.

-It's pretty much a lock that March will finish with a below average temperature which means that February-March 2013 will be the 1st time with back to back below average temperature months since May-June 2011.

-So far this month, only 6 days with a high temperature of at least 32F…

*Instead of melting the snow pack were adding to it across much of the Upper Midwest.  As of March 19, 2013:  85% of the Upper Midwest was covered by snow vs. just 2% at this time last year.

*This next image shows the snow water equivalent as of March 19, 2013.  There's a lot of water in the snow pack in much of Western-Northern Minnesota (as much as 2-3" in spots) This isn't good if you live in the Red River Valley or near any river in Minnesota for that matter.

This snow pack isn't going anywhere thru at least April 1st.  This is bad because eventually temperatures will warm up (possibly significantly) and this snow will melt.  The longer it stays cold (no melting) the worse it may be in terms of flooding as we head through April.  The ideal scenario is that we see a slow thaw, about a week or so of temperatures in the 40s, lows near freezing with no precipitation.  Getting that to happen is easier said than done.
