While April will not be as cold as March, thanks to the strengthening sun, pockets of cold air will continue their invasion from the northern Plains to the Midwest and Northeast into the first half of the month.
As we progress through spring, warmth is highly dependent on sunshine. Through the first half of April, most of the northern tier states should bag more sunny days, compared to the first four weeks or so of March.
