Another storm has moved in, and it’s dropping more snow in the mountains. The low is currently sitting just off the shore, and is pushing in plenty of cool, moist air. The Cascades have already started accumulation snow, and some of the mountain roads are a little slippery.
A Winter Weather Advisory is still in effect for this storm. It includes all of the Cascade areas, including some of the higher foothills, and east slopes. The advisory will lift Saturday night at 11 p.m. for the Southern Cascades, 4 a.m. Sunday for the Northern and Lane County Cascades, and 11 a.m. Sunday for the East Slopes. Cities included are Government Camp, Oakridge, Diamond Lake, Crater Lake, Bend, La Pine, Sisters and Sunriver. The current snow level is around 3500 feet on the western side of the mountains, but it is likely mixed precip is falling as low as 2500 to 3000 feet. Overnight, the snow level could drop as low as 2000 to 2500 feet. (See Images for Local Snow Levels or for more areas, click here. )
For Sunday, the moisture will still be in place as the low moves on, so I think isolated showers are still possible, but we’ll likely see more periods of dry weather rather than wet. Clouds will stick around, with a break of sunshine possible.
Thereafter, a large area of high pressure is sitting out in the water, with a decent trough to the north in the Gulf of Alaska. I think a new storm or two could fire up right along the jetstream where the two features meet. However, the path of the storm will make a huge different in our weather, depending on where it moves. Monday, we should clear out a little with some morning fog and partly sunny skies. Temperatures will start to warm up as well. With the next storm, we will be in the warm sector until the time (if the time comes) for it actually move through. However, being that it is November, I’m not anticipating a huge warm-up.
Models are currently dropping the low out of the main circulation and cutting it off from the jetstream by Monday night into Tuesday. If that happens, the key will be pinpointing where the low parts ways with the main flow. If it stays further off the coasts, as models are suggesting, there may only be slight chances of showers along the coast Monday through Wednesday, with the rest of the area bone dry. If it sets up closer, we all could have chances of showers for the first half of the week. Right now, I’m leaning towards the drier scenario since this is the first day all four of the models I checked were very similar.
Thursday will be the in between period as the low will be the furthest south in its trek, and our new storm will be lining up from the northwest. Friday night, the first line of showers will move back in, with scattered showers and cooler air settling in for Saturday.
DON’T FORGET TO SET YOUR CLOCKS BACK 1 HOUR BEFORE HITTING THE SACK TONIGHT! IT IS ALSO TIME TO CHECK YOUR SMOKE ALARM AND CARBON MONOXIDE DETECTORS AND MAKE SURE THE BATTERIES ARE FRESH! ENJOY THE EXTRA HOUR OF SLEEP!
