What a difference a year makes! WELL BELOW NORMAL APRIL ACROSS THE US!
What I find interesting is that the center of the "colder than average" area has stayed virtually the same since the beginning of the year.
Here are the April temperatures compared to the average across North America
Once we include MARCH AND APRIL, the map looks virtually identical
How about FEBRUARY, MARCH and APRIL? Little change in the map
The entire year from JANUARY through APRIL shows how the center of the cold evolved over the last 4 months
The BIG QUESTION will be whether or not the CORE OF THE COLDER THAN NORMAL AIR breaks down, drifts west or east or expands? More on this later.....
