July 29, 2018 – Smoke will help to keep daytime temperatures cooler the next couple of days. Then a gradual decrease in high temperatures is expected next week but temperatures are expected to remain a little above average.

Discussion (Today through Tuesday)

The upper level ridge will remain overhead on Sunday before shifting to the SE early next week. Smokey conditions will make for a tricky temperatures forecast the next few days especially over the north end of the valley where the smoke is thick.

Highs Sunday and Monday in the north valley look to reach 101 to 107 and will be right around 100 in the south valley where there will be a Delta influence. A gradual cooling trend can be expected starting Tuesday as we see the ridge push south and east.

Models do start to push some monsoon moisture north into the SE part of the CWA by Monday night. Isolated t-storms will be possible in the far SE Monday and Tuesday but the better chances will remain south and east of us.

Extended discussion (Thursday through Sunday)

The upper level ridge that has dominated the weather pattern for the better portion of July will begin to shift eastward starting the middle of next week. At the same time, a series of shortwave troughs will pass through the Pacific Northwest, resulting in lowering heights and increasing onshore flow. High temperatures should trend back to within a few degrees of normal. Dry weather will likely continue through the extended period.
