Our typical summertime thunderstorm events usually only produce a few isolated cells through late afternoon, but the past few days this has not been the case. Monday featured widespread thunderstorm activity, accompanied by heavy rain and hundreds of lightning strikes. Tuesday’s storms occurred in waves, one which moved north along and east of the Cascades in the morning, and another that moved north mainly through west side valleys in the evening.
With Tuesday’s storms, small hail was reported with the heavy rain and frequent lightning. In fact, hail 1/2 inch in diameter fell in north Medford near the airport. The storms will continue through the overnight hours as a cold front moves through, bringing another round of rain and lightning in the early morning hours of Wednesday. Temperatures will be much cooler on Wednesday as well. Expect highs anywhere from five to ten degrees cooler than previous days, with locations in the Rogue Valley only reaching the lower 80′s. Showers behind the front will continue Wednesday and may contain embedded rumbles of thunder.
The cool down mid-week will only be temporary. As high pressure builds back into the northwest, mostly sunny skies will take us through the weekend. By next week, highs will be warming up back into the middle and upper 90′s in the Rogue Valley and northern California.
