ST. PAUL (AP) -  Weather experts say it's difficult to know why Minnesota had such high temperatures in February, but the long-term warming trend goes back about 45 years.
Temperatures in the Twin Cities and southern Minnesota soared into the 60s a couple weeks ago. The Twin Cities is in the middle of an 18-month streak of warmer-than-normal temperatures.
Minnesota Department of Natural Resources climatologist Kenny Blumenfeld says that the decadeslong trend is the strongest in the winter. He says this year the state has had an unusually warm swing on top of that.
Blumenfeld says he wasn't surprised that forecasts several months ago for a cold and snowy winter were wrong. He said an analysis by Minnesota's climatology office shows three-month forecasts are wrong more often than they're right.
