The Non-Storm/Colder Next Week

November 27, 2013; 1:58 PM

A quick update today.

California Storm:

What storm? The closed low west of California now looks to track so far west through Friday morning, then back southwest into the weekend that it cannot bring any important precipitation to Southern California. The models have done a horrendous job on this feature since last week but have been gradually backing off on it over the last two days.

A band of clouds moving through Thanksgiving Day could produce a sprinkle or light shower in a few spots but too much dry air in the lower levels, plus southeast lower-level winds will prevent anything more than that. It's not out of the question there could be a sprinkle along the coastal areas for a time Friday but again, a southeast low-level flow will keep it mostly rain-free. The good news is that people traveling will not have any bad weather on the roads. Those shopping will be able to leave the rain gear behind.

Change in the Pattern Next Week:

After how bad the models did from last week for this week, I hesitate a little on saying what is going to happen next. That being said, a weather pattern change does seem to be in the offering. I will not be providing details right now, like how much snow there will in the Intermountain West and the Sierra. It looks like the Cascades of Washington will get some important snow Sunday and Monday with the mountains of Idaho and western Montana getting into the act later Sunday into early next week. It's likely to snow some farther south, but those details are much more in question and dependent on where any upper-level low forms. The models do show below, and even much-below temperatures spreading south through western Canada into the Northwest by early in the week and spreading farther south the rest of the week. There looks to be a rather significant time when it will be much colder than normal in the Inter-mountain regions, the Northwest and even parts of California and northern Arizona.

Have a great Thanksgiving, one and all.
