It wasn't so happy in the Upper Midwest and near Chicago this weekend when WINTER made a comeback with accumulating snow. Several inches fell from North Dakota to Northern Illinois, but the good thing about the late April sun is it melts snow very quickly. CLICK ON IMAGES FOR A LARGER VIEW.
That cold front ushered in some frost and freezes into the interior Northeast this morning as well.
But, April overall has made one of the most dramatic changes from really cold last year to much warmer this year with the nation overall trending 6th warmest in 30 years, 4th wettest and 9th least snow in 30 years.
Recall last year trended 2nd coldest and 2nd snowiest in over 30 years for the U.S. overall. Tornadoes this year were way up with 227 reported which is 75% more than last year and 29% above average.
This week (29 Apr - 5 May): trends about average for the U.S. overall with cooler conditions than last year but still ranking 14th warmest of the past 30 years. It's wetter than last year with a severe weather outbreak likely for the South Central U.S. The nation overall looks to trend 3rd wettest of the past 30 years.
Next week (6-12 May): Is cooler than last year nationally trending 13th coolest of the past 30 years but wholesale flip flop from driest in 30 years last year to wettest in 30 years this year. More severe weather and tornadoes very likely across the Deep South with a clash of cold to the North and warm to the South.
The spring national year-over-year temperature trends show the really cold start to March but the much warmer April conditions but now back to a colder trend for much of May.
The year-over-year May trends across the world show the U.S. much colder than last year with the month overall likely to trend 13th warmest in 30 years, #1 wettest with severe weather way up over last year. Recall last year was the #1 warmest May in over 30 years in the U.S., 7th wettest in 30 years with way below average tornadoes. Europe also looks to trend dramatically cooler than last year so the very positive seasonal sales trends in April will soften quite a bit in May.
If you're looking for something to do this weekend, consider getting up early in the morning to see 40-50 meteors per hour as the Earth goes through a debris field from Haley's Comet. Sunday pre-dawn is the best viewing time with the new moon making it very dark.
