Freeze likely tonight, but warming begins Tuesday

By  | 

November ended on a warmer-than-normal note, but cold air arrived just in time for December to start with a shiver!

A howling wind last night helped hold up our temperatures, so we cooled only into the low-to-mid 30s to start our Monday morning. Gusty wind makes for a lower wind chill, but it makes for warmer air temperatures. That wind will relax tonight. That will allow temperatures to drop to 5-10 degrees colder tonight as compared to last night. That means many of us will freeze, so be sure to bring in your plants and leave your faucets dripping tonight.

TONIGHT & TUESDAY

This evening will cool quickly from low 40s to upper 30s by 7-8 PM. Temperatures will drop steadily through the night beneath a clear sky. We will drop to below freezing around or just after 10 PM. Our Tuesday morning will start with some cold upper 20s around 6 AM. We will warm with sunshine, but we will struggle to reach the mid-40s by noon. The afternoon may struggle to reach into the 50s in some areas, but many of us should manage highs in the low-to-mid 50s even if only briefly.

OUR NEXT WEATHER MAKER

Gradual warming will occur on Wednesday and Thursday. That warming leads us to our next chance for rain starting late Thursday night or early Friday morning. Our next weather maker is a swirl of low pressure in the Pacific Ocean more than 400 miles west of California Monday evening. That system will get picked up by a 140-150 mph jet stream on Wednesday and race eastward. It will bring widespread heavy rain to Southern California and a heavy, wet snow snow to much of Colorado and New Mexico through Thursday morning. It will also bring us some rain. That rain will arrive after midnight Thursday night and fall throughout much of Friday. The rain will gradually end from west to east between 3 PM and 6 PM Friday. Be aware the timing may alter a bit between now and Friday, so check back for forecast updates through the week. The bottom line now is if you have outdoor plans on Friday, it may be wise to consider moving indoors.
