GRAND JUNCTION, Colo. (KREX) — The Western Slope will continue to enjoy plenty of sunshine this weekend. If you head out, you might want to bring your sun block!
Our Thursday system is slowly advancing toward the Atlantic Seaboard where it should deliver several feet of snow to the beach communities north and south of around Cape Cod, MA. This will be a significant Nor’easter storm system for coastal New England that had it’s origins on the leeside of the Colorado Rockies just outside Pueblo. Meanwhile, the Western Slope will remain dry and mild as a ridge of high pressure continues to influence our weather. Still expecting a chilly start Saturday morning for many locations, but a good temperature recovery is expected Saturday afternoon with the highs very close to the seasonal average near 40°. Quiet weather will continue through the rest of the weekend.
Sunday afternoon there will be a cut-off low pressure system advancing from Southern California, across the Desert Southwest. The track for this system (today and subject to change) remains too far south. This low will traverse across Arizona and New Mexico and it will push clouds as far north as the I-70 corridor for Monday and Tuesday. If the track redirects further north, beneficial snow will be had. The more important issue at hand and the more delicate, this southwest low pressure system will be working in tandem with another low pressure system/cold front. This other system will have a genesis site in the PACNW and will traverse across the western third of the U.S. during the same timeframe. These systems will replace the reigning high pressure system and as such unsettled weather is expected to develop for the middle for next week. This could also open the window to a more prolific pattern that will allow more PACNW storms to roll through the region uninterrupted by a ridge of high pressure. Lots to sort out… so for this weekend… get outside to play and enjoy the mild conditions because late next week there will be colder temperatures as a result of this short term pattern developing.
