Thunderstorms and rain showers moved through Friday morning and brought lightning to not only northern California and the basin, but also The Rogue Valley and coast. We did see measurable rainfall, but amounts were very small – only .01 of an inch was seen at the airport in Medford, and amounts elsewhere weren’t much more.
We did see another, smaller, round of storms develop in northern California during the early afternoon, but those dissipated with the loss of daytime heating. The chance for a thunderstorm is back tomorrow for the Klamath Basin and parts of the Cascades, but elsewhere we will see a dry Saturday. Not just dry, but hot. The triple digits that are possible in the valley and northern California are just the first day in what may be the hottest stretch of the year so far. A heat wave is even possible by next week. That would mean two or three or more days with temperatures above 103 degrees, and nights that didn’t dip below 65 in between. A heat advisory is typically issued in conjunction with the heat wave.
The National Weather Service is predicting that this could be the longest stretch of hot weather the Pacific Northwest has seen in years. It’s due to a massive, and strong, ridge of high pressure building in the upper levels of the atmosphere over the course of next week. This keeps any cooler air from tracking through the area, and allows for substantial warming. Some models are predicting highs near 105 for the valley, and the same for northern California. The ridge won’t stop the rain and lightning chances, though. A few storms are possible next week along and east of the Cascades and in northern California.
