Elliott's April outlook:
Let's talk about #April. Many forecasters are calling for below-avg. temps and even mentioning the threat of a late-season snowfall. In my opinion, this is unlikely. Why? First, the MJO may be active in phases 5-7.. all of which are "warm" phases in an ENSO-neutral April..
Next, the Pacific/North American (PNA) pattern should remain negative. A strongly -PNA indicates a deep trough, or dip in the #jetstream, across the West and a mean ridge in the East. Thus, I expect temps to be 2-4°F above normal for the month in southeastern PA.
