Powerful winds whip through San Diego County

Posted: Updated:

SAN DIEGO (CBS 8) - You've heard about this latest major winter storm (understatement)to make its way through the Eastern half of the country. As much as two feet of snow expected in some spots of the upper Midwest, and bitterly cold temperatures everywhere back East are making life very, very wintery for those back there. With today being Ground Hog Day, what sort of shadow/no shadow do you think folks back there are hoping for!?

Here's a look at what's going on:

As this storm makes its way to the east, cold air will be filling in behind it. And THAT is where the connection to San Diego's weather comes into play.

This cold air filling in is in the form of arctic high pressure - that will fill into the Great Basin Wednesday. That will produce some Santa Ana winds for Southern California, and those winds will be quite strong through Thursday morning. The National Weather Service here in San Diego has issued a High Wind Warning in effect through Thursday morning, and winds will be strongest later this evening into Thursday morning.

It's a "cold" Santa Ana wind, but that's only because of the origin of the air mass. In other words, these offshore winds will still be warming up as they come off the mountains and towards the ocean. That downslope warming warms the dry air at about 5 degrees per 1,000 feet of elevation. During months like September, this frequently produces temperatures in the 80s and 90s at the beaches. . .but this week, that air is so cold that even though it will still be warming up from the downslope warming, temperatures will only get into the mid 50s Wednesday and Thursday. That's running about 15F to 20F degrees colder than normal.

Once these winds let up, temperatures will be warming up, too. By the time our weekend gets here, we'll be back in the low 70s. Until that time, the windy weather will be the worst of the wintery conditions here for now.

Matt Baylow is the Chief Meteorologist for KFMB-TV, and you can catch his weather forecasts each weeknight at 5pm, 6:30pm, and 11pm on San Diego's weathercasts first broadcast in sparkling High Definition. There's never been a "clearer" weather forecast, that is, if you can get past the hair that's out of place. And sometimes the pattern on the tie. Did we mention the tie?
