Redding has now had 46 days of 100 degrees or hotter this summer.
This morning's satellite picture (below) shows the high pressure area over the western U.S. with a weak upper level low pressure area off the coast. The low has pulled subtropical moisture and clouds northward and you can see the clouds wrapped around the low. The low will continue moving slowly eastward and will be over Northern California Sunday. This system will weaken and dissipate Monday and Tuesday as it pushes eastward and runs into the high pressure area. Today and Sunday the north state will be partly cloudy to partly sunny with a few showers and thunderstorms over the foothills and mountains and a chance of isolated showers and thunderstorms in the valley. The clouds will affect the temperatures and afternoon readings will range from a couple of degrees below normal to a couple of degrees above normal. Winds will increase from the south and southwest in the afternoon. Monday and Tuesday we will see mostly sunny skies with afternoon cumulus clouds and possible thunderstorms over the higher elevations. Temperatures will be near normal.
While the high pressure ridge is expected to remain over the western U.S. for at least the next week, there will be another weak low pressure area off the coast by next Thursday (see map below). This won't have as much sub tropical moisture but could trigger isolated afternoon thunderstorms over the mountains Thursday through the weekend. Temperatures Wednesday through the weekend will be normal to 5 degrees above normal.
