For April from Maxar early today: they have slightly cooled the SE SE of a line from Greensboro to ATL to Mobile to less than a degree warmer than normal due largely to the early month cold and they noted the -NAO for even cooler risk:
"Our final pre-month outlook for April undergoes further warm changes
across the mid-continent where an area of 3°+ anomalies have been
added. Meanwhile, cooler trends are noted in the Southeast and
Northwest. After a cool start in the Midwest/East, a broadly-warm
pattern is expected to take shape as troughing becomes prevalent over
the Northwest, promoting ridging downstream. Pattern signals favoring
warmth include –PNA, +WPO, and –GLAAM while a potential –NAO
does suggest cooler risk in the East."
