This blog will be issued every Monday, Wednesday, and Saturday morning and updated if the weather is changing or critical or interesting weather events are occurring.
If you look at climatology we are now out of our hottest time of year...the last week of July and the first week of August. It has been hot, Redding has now had 49 days of 100 degrees or more.
Today through Friday we will be dealing with the weak upper level low pressure area that is along the coast. The system will try to move eastward but will be stopped by the strong high pressure ridge that continues just to our east. This means through Friday we will continue have afternoon and evening thunderstorms over the higher elevations with a slight chance in the Redding area. Temperatures will be at or just above normal. Winds will be light nights and mornings and southerly in the afternoon.
During the weekend a low pressure trough will move through western Canada and the Pacific Northwest (see map below). This will push the high pressure ridge eastward and kick the low pressure area northeastward. The trough will bring a few clouds to the far north end of the state and could trigger a shower or thunderstorm over the areas near the Oregon border. Temperatures will be near or just below normal and gusty southwest winds will occur in the afternoons.
Monday and Tuesday the north state will see mostly sunny skies. The cooler air that follows the trough will keep temperatures a little below normal. Wednesday high pressure will build off the coast. This means sunny skies and hotter temperatures.
