The West simmers, the East washes away

|

Chicago’s string of sub-normal days extends to six with today’s reading in the lower 60s, but cool air will briefly relax its grip on the city Wednesday with temperatures expected to top 70º.
Elsewhere, national weather has taken some harsh turns. The same storm system responsible for Chicago’s cool temperatures has simultaneously delivered a multi-day deluge of rain to New England. Rainfall records have toppled in Massachusetts, hardest hit of that region’s states.
At only 15 days into the month, Salisbury, Mass., has logged 18.82 inches of rain, blowing away the state’s previous full-month May record of 15.60”.
The opposite end of the nation, meanwhile, is simmering in unprecedented early-season heat. Some Oregon records established on Monday: Portland, 95º (old record 81º); Astoria, 90º (76º); Medford, 96º (92º). Stockton, Calif., 97º (89º).
