Heat & Now Thunderstorms

video preview image

High pressure will continue to usher in hot weather into Saturday with highs remaining 10 to 15 degrees above normal so it will continue to feel like mid-Summer instead of only 11 days away from Fall! A low pressure located over Southeast Nevada will begin moving north on Thursday and will filter in monsoon moisture and instability into the region. Thursday and Friday afternoons there will is a chance for isolated thunderstorms along and east of the Cascades and also in the Siskiyou Mountains. West Siskiyou county has a slight chance for thunderstorms, but most will be confined to the higher elevations.

This system will continue to push north on Saturday and will only bring a slight chance for a thunderstorm in the Cascades, otherwise Saturday will be another quite sunny day for most areas. Sunday is the end to the heat wave a dry conditions as we transition into a cooler and wetter pattern. Showers will develop at the coast Sunday mornings and spread inland during the day bringing periods of heavier showers at the higher elevations. There will also be the threat for isolated thunderstorms in the afternoon Sunday, mainly along and east of the Cascades but a few could pop up in west side valleys. This pattern change will be due to a longwave trough and the timing of disturbances within that system could bring isolated showers Monday and Tuesday, mainly at the coast.

While all areas may not see showers early next week, we will all feel the cool down as highs drop 20 to 25 degrees from today which is about 10 degrees below normal! Follow me on Facebook for more weather updates and to share you weather photos!
