Early June is expected to bring above average temperatures to the inter-mountain west (inland from the coast range summits east to the Front Range of the Rockies) and the SW, SE and much of New England. Otherwise near normal temperatures should be the case, except a little cooler than average over the Central and Northern Plains, and in the vicinity of the western Great Lakes. It should be fairly wet through this period over the Central-Northern Plains and along the east coast, and especially over Florida where the tropics show signs of becoming active.

Temperatures will begin to moderate early this week over the Northeast and Ohio Valley as the upper ridge running N-S from Hudson's Bay to SW Texas slowly shifts to the east to a position N-S from Western Lake Erie to the Florida Panhandle by Wednesday. It stalls in place there and is reinforced over the central eastern Seaboard as the Bermuda ridge rapidly builds over Virginia. The end of the week and weekend over the east is going to be hot and muggy. An upper trough currently over the NW pushes east to over the Central and Northern Plains by the end of the week. In the West, a weak ridge rebuilds along the Pacific coast only to be partially replaced by an new but weak trough over the Pacific NW at the end of the week. Most of the heavy precipitation this week should be confined to the Northern and Central plains and the upper Midwest, although thunderstorms, sometimes severe, are also expected from W Texas north thru the Plains, spreading to the upper Midwest by mid week. Heavy thunderstorms should also begin to build over Florida toward the end of the week.

With a cool but moderating start to the NE early this week, NG for electrical power demand will be a little lower than normal (no AC requirements in the NE but need for a little morning heating). Injections should rise through mid week as temperatures moderate,and then fall toward the weekend as the NE and Mid-Atlantic get downright hot and muggy. Injections to be reported this Thursday should be near to a little above average, and a week from Thursday the same. Its a slightly bearish pattern.
