Increased Thunderstorm Possibility Across Douglas County Today

4:48 PM · Jul 30, 2021

Along with temperatures that will come close to 100 degrees again today, there is an increased change of thunderstorms this afternoon and evening around Douglas County. Also, forecasters have pushed the possible thunderstorm boundary further west across Douglas County. Here is the latest discussion from NWS Medford: DISCUSSION...Another day of hot temperatures and thunderstorms is expected today. Despite some cloud cover this morning, temperatures should reach into the upper 90s and triple digits again today for west side valleys, and an Excessive Heat Warning remains in effect for today. Regarding thunderstorms, we`re expecting a stronger shortwave trigger to move through this afternoon, so we`re expecting a greater coverage of thunderstorms today. 305 strikes were recorded with yesterday`s storms, and today`s activity should exceed that. Just about everywhere east of the Coast Range could see some storms today, however, high resolution models are showing convection weakening as the cells move north of the Umpqua Divide. Rainfall amounts with yesterday`s storms were generally in the 0.25"-0.50" range, though there was a report of 0.65" in Ruch yesterday. This morning`s (12z/30th) KMFR sounding shows 1.32" in precipitable water, which is up from yesterday afternoon`s (00z/30th) sounding of 1.15". So we do expect storms to be wet again this afternoon, especially under the storm cores. All of that to say there will likely be some locally heavy downpours this afternoon under any of these thunderstorms, especially west of the Cascades. The only update needed was to expand some shower mention across the East Side for this morning. Radar is showing returns across Modoc, Klamath and Lake counties this morning, so the forecast was updated to better reflect this. Otherwise, the going forecast is on track and no other updates are needed.
