A quiet and dry day is ahead for Thursday as high pressure ridging builds into the West temporarily. Temperatures will trend 8-10 degrees warmer today, although the clear skies throughout the morning will allow us to start off much cooler than we’ve seen recently. With that said, a big warm up will bring temperatures near 80 across West Side Valleys.
Afternoon showers and thunderstorms are likely into Friday afternoon, however the computer models are struggling to show exactly how big this threat will be through the Friday/Saturday time frame. I have removed the shower/storm threat from the Rogue Valley into Friday and Saturday, and removed any afternoon activity from Saturday for the region as a whole. On Friday though, showers and storms are likely by late afternoon over the Cascades, the Basin and Western Siskiyou County.
Building cumulus clouds are likely throughout the weekend, but computer models are now hinting at no afternoon convection Saturday and Sunday. For now, we will go with this and adjust the forecast as needed. Early next week, afternoon showers and storms look to be returning for the Klamath Basin, Cascades & Northern California.
