Another Cold, Wet Period Likely In The East In Early April

 

We are keeping an eye during April 6th through 12th on the potential for much below-normal temperatures from the Northern Plains through Midwest and heavy rains from the Mississippi River Delta through the Tennessee Valley.


 

This potential is related to anomalous 500-hPa ridging forecast over the Bering Sea and a downstream trough over Hudson Bay that will likely help drive Arctic air southward. Typically observed temperature anomalies from this ridge/trough combination are shown here. (2/2)


 

We continue to favor below-normal temperatures and anticipate related -weather hazards stretching from the Northern Plains through Great Lakes during early April.
