Weather Discussion: The first 9 days of July were sunny with above normal temperatures. The next 9 days will be mostly sunny with a few clouds at times and temperatures up to 10 to 12 degrees below normal for this time of year.
A low pressure trough that is currently over western Canada is slowly sliding southward down the coast. The main part of this system will move slowly across the Pacific Northwest on Wednesday and Thursday, with the southern end brushing Northern California. This system will trigger some afternoon and evening thunderstorms over the higher elevations to the north and east of Redding, Tuesday through Thursday. Wednesday afternoon we could see the thunderstorms get as close as Lake Shasta but I think they will miss the Redding area.
The big effect this system will have on our weather is cooling. Monday (the 11th) will be sunny with a few clouds and high temperatures in the lower 90s. Tuesday and Wednesday will be sunny in the morning with increasing clouds during the afternoon and early evening. High temperatures Tuesday and Wednesday will be in the mid to upper 80s. The main portion of the low pressure trough will be east of our area by late Thursday but the cooler air will remain over the north state.
Thursday and Friday will be sunny with high temperatures in the upper 80s and lower 90s. The weekend will be sunny and a little warmer with high temperatures back into the low to mid 90s.
Extended Weather Outlook, July 18th through July 24th: A weak low-pressure trough will linger along the west coast. Redding will see mostly sunny conditions but temperatures will still be below normal with highs in the mid 90s. It does look that we will see a little warming by the 23rd or 24th and could be back near the 100-degree mark. Check out the mid-week update here.
