What To Watch Fore(cast) - May 30 - June 5

Highlights:

Hot and wet in the East - The eastern third of the nation will be seeing warm and wet weather this week as unstable air lingers over the region.

Pacific Northwest finally moving into summer? - After a few more rounds of wet weather this week, this weekend could mark the start of drier, more summer-like weather in the Pac. Northwest.

The onset of cooler weather - The Midwest and Northeast may see the start of a period of below-normal temperatures later this week.

Discussion:

The first week of June marks the beginning of an active weather pattern in the Mid-Atlantic and Northeast, with several storm systems moving through the region over the next 7-8 days. These systems will keep the air relatively unstable throughout the eastern third of the nation, which will initiate scattered showers and thunderstorms all week. More organized and more severe storms will be possible along the onslaught of cold fronts that will move through the Mid-Atlantic and Northeast, which means plenty of opportunities to go chasing!

Following these storms will be increasingly cooler air, which appears to favor sitting over the Midwest and Northeast this weekend, and it looks like it is setting up for an extended stay as the cooler temperatures extend into next week. A long wave upper-level trough is attempting to settle into these areas in the long range, as an active storm track appears to continually reinforce the trough.

As the weather pattern begins to shift from what we have been seeing for the past several months (cool in the west, warm in the east), the change in the ridge/trough pattern in the east will mean closer to normal temperatures in the Western U.S., which will help keep storm systems further north and out of the Pacific Northwest. After a couple more systems push through, the Pac. NW will see the beginning of drier and warmer weather as summer tries to push into the region.
