bluewave Posted March 17, 2013 Share Posted March 17, 2013 Waterloo, Iowa is experiencing about as an extreme reversal in temperatures that you can imagine from one March to the next at any given location in the U.S. March 2012 had an average temperature of 51.1 for a +15.3 departure. This March so far is averaging 24.3 degrees which is a -8.1 degree departure. More cold is on the way which will push the monthly temperature departure even lower this week.

Chicago WX Posted March 17, 2013 Share Posted March 17, 2013 A few other cities in the Midwest/Northern Plains experiencing a "nice" reversal. Well, everyone is for the most part...but here are a few better ones. Dubuque IA March 2013: 25.2º -6.9º (through 3/16) March 2012: 50.2º +14.8º Grand Forks, ND March 2013: 14.5º -6.5º (through 3/16) March 2012: 38.0º +12.8º Mason City IA March 2013: 23.3º -6.2º (through 3/16) March 2012: 48.9º +15.9º Rockford IL March 2013: 27.5º -6.6º (through 3/16) March 2012: 52.4º +15.2º International Falls MN fell to -28º this morning, which shattered the previous record min temp for March 16 (-18º in 1909). Here in Indiana, average temperatures are running 13-17 degrees colder than last March, through yesterday (average temp comparison below for six sites). This will grow larger this week as temperatures will be solidly colder than normal...all the while last March 17-24 had big time positive departures. Bloomington 2012: 49.8º 2013: 36.5º Evansville 2012: 53.1º 2013: 39.8º Fort Wayne 2012: 46.7º 2013: 32.5º Indianapolis 2012: 50.6º 2013: 35.2º Lafayette 2012: 50.7º 2013: 33.3º South Bend 2012: 47.6º 2013: 31.8º Link to comment Share on other sites More sharing options...

In some ways this reminds me of an opposite reversal that we saw here in the Northeast from December 1989 to 1990. Burlington, Vermont experienced a 22.5 degree temperature swing in the warmer direction after the coldest December on record there.

Chicago WX Posted March 27, 2013 Share Posted March 27, 2013 The cooler high temperature daily departures of this March can't match last year's super warm departures in the Midwest, but as witnessed...there has been quite the turnaround. Chicago: 27.2º colder with average high temperatures this March versus last March, through yesterday. Detroit: 23.0º colder Milwaukee: 25.7º colder Minneapolis: 25.4º colder Des Moines: 27.5º colder Indianapolis: 25.8º colder Moline: 27.4º colder Columbus: 20.7º colder St. Louis: 23.7º colder Marquette: 23.7º colder La Crosse: 27.9º colder Duluth: 19.8º colder Moline IL hasn't had one day this month with an above normal high temperature. LaCrosse, Milwaukee, and Minneapolis have had only one such day. Note below, Milwaukee was a rather remarkable 62º colder on March 20 this year, versus last (21º vs 83º). Chicago was 60º colder and Marquette was 59º colder. Daily high temperatures for March 2012 and 2013, and normal high temps, for the above 12 cities.

Roger Smith Posted April 3, 2013 Share Posted April 3, 2013 The same thing applies to Europe, in Britain the CET value for 2013 was 2.7, for 2012 it was 9.2. The rank was something like 5th warmest in 350 years to coldest in modern times. Link to comment Share on other sites More sharing options...
jsw Posted April 3, 2013 Share Posted April 3, 2013 Don't really know where to put this - wicked windy here yesterday with gusts up to around 35 mph. Sunny and around 30 degrees today. No wind. Snowboarding will be very good on Sunday. Mount Snow, and also hiking up my father's meadow/hill today and snowboarding down. Lots of snow up there still. Just OBS. Again, not sure where to put this, and sorry if wrong place. Couldn't find a current temp/OBS thread. Mods go ahead and move if not right place. Can't talk right now. Leaving out words. Haha.

bluewave Posted April 3, 2013 Author Share Posted April 3, 2013 You can see how the March temperature patterns reflected the shift in the blocking locations from the Great Lakes region in 2012 to the Arctic in 2013. March 2012 featured the strongest March ridge near the Great Lakes since the late 40's. The 500 mb heights this March were the second greatest on record for the area around the Davis Strait.

WEATHER53 Posted April 4, 2013 Share Posted April 4, 2013 What part does global warming play in this very cool March and perhaps especially in light of the reversal from last year. Link to comment Share on other sites More sharing options...
