Fire Weather Threats Continue in Southern California

A storm system passing over the west coast ridge and into the Great Basin the next couple of days will improve air quality across the Pacific Northwest, and bring a wintry mix to the northern Great Basin and northern Rockies. Gusty winds will increase fire weather threats across portions of northern California, and continue to exacerbate ongoing fires across Southern California. Read More >

Rain returns to the region Saturday and Sunday. The rain will spread into the region from the south Saturday afternoon and evening, and exit the region to the east on Sunday. Highest rain chances are Saturday night along and east of Interstate 35/35W. Rainfall totals are generally expected to be less than a half of an inch, and some locations west of Interstate 35 may not receive any rain.
Maybe you've heard a rumor about wintry weather before Christmas? It's true, some of the forecast data does suggest a weather pattern favorable for winter weather. However it's such a long way out, weather forecasters have to deal with uncertainty. One of the best ways to show uncertainty is with probabilities. Hear's a chart that shows the highest probability of a certain type of weather December 21st through December 25th. See why snow and ice may be possible, but the most likely forecast is cold and dry.
Forecast models are showing cold air arriving next week around December 22nd and 23rd (on average). What we do not know for sure yet is exactly when the cold air arrives, how cold temperatures will be, and if there will be any precipitation and what kind. We will be providing updates when/as we acquire better confidence in the late week forecast.
With very little rainfall the past several weeks, widespread moderate to severe drought has overspread much of the region. Burn bans are in effect for many counties across the region due to the resultant increased fire danger.
Another cold front will move into the region this evening and overnight. This front will result in a north wind shift, but gusty winds are not expected until Thursday. Low temperatures tonight and Thursday morning will be in the 30s for most locations.
