March 25, 2021 – Seasonable temperatures and some scattered, light mountain showers are expected today. Otherwise, dry weather and and a warming trend is seen Friday into the weekend.
Another weak inside slider type of system will move through the region today. This may bring some light amounts of precipitation to the foothills and mountains with the valley expected to remain dry. The best chances of any precipitation will be over the western slopes due to orographic enhancement.
Maybe some local 1-2 inch snow amounts over the higher elevations will be possible. Trough passage will occur fairly early today. This will allow for a shift in wind direction within the valley mainly during the late morning and afternoon hours to a northerly direction for most locations. Winds have already shifted over the northern end of the valley this morning.
Cooler today then warmer Friday with highs warming in the valley into mostly the mid 70s. Northerly winds continue but much weaker than the last event with sustained winds in the valley generally between 10 and 20 mph with some higher gusts.
High pressure will continue to build on Saturday with highs well into the 70s for the valley and around 80 degrees for the far north end of the valley. Mountains will mainly warm into the 50s and 60s. Continued above normal temperatures for Sunday under the ridge of high pressure with temperatures slightly warmer than Saturday’s highs.
Extended discussion (Monday through Thursday)
Monday temperatures will cool a little due to a trough passing by the region to the north and maybe bringing a few showers over the far portions of Shasta County.
Behind the trough winds will increase again late Monday into Tuesday before subsiding Tuesday night and Wednesday morning. Breezy to windy conditions continue to look possible at this time.
The valley could see temperatures in the 80s for next Wednesday and Thursday as high pressure builds over the region with perhaps a few of the warmer spots on Tuesday warming to around 80 degrees.
