Murphy’s law for meteorology: The more important the event, the more complicated the weather pattern will be.
It had been looking like Friday and Saturday would be partly cloudy with showers in the far north end of the state near the Oregon border. However, this morning’s satellite picture, shown here, shows a large area of sub-tropical cloudiness and moisture being pulled northward west of Hawaii.
This moisture will get caught up in the westerly flow and will end up over Northern California Thursday and Friday. The map below shows an upper air map for Friday; the green area represents where that subtropical moisture — or clouds — will be Friday.
While there will be a lot of clouds, there really isn’t going to be a way to squeeze the rain out of them. So while Thursday and Friday now look partly cloudy to cloudy, I still think most of the rain will stay over the foothills and mountains to the west and north of Redding, with maybe a light shower or sprinkle in Redding. Since this moisture is from a subtropical source, the temperatures should be in the 60s. Skies will be clearing Saturday with afternoon temperatures in the low to mid 70s.
