METEOROLOGIST MARISA WOLOSZYN’S FORECAST DISCUSSION:
Sunday was the warmest day, thus far, in 2013; high temperatures were in the mid to upper 80s for the valley and Umpqua, low 80s along the coast. A few thunderstorms popped up late in the afternoon in the Umpqua Basin, although most of the activity stayed to the south.
The thunderstorms were due to day time heating, plus an upper level low located over northern California. The low will continue to spin in northern California Monday through late Tuesday, keeping a similar weather pattern each day. Monday and Tuesday will be partly sunny for most of the day, with high temps climbing into the low to mid 70s. Daytime heating + the enhanced energy from the low will pop a few thunderstorms in the late afternoon and evening across western Oregon. These thunderstorms will produce lightning, heavy downpours, grauple (soft hail) and gusty winds.
The weather quiets down Wednesday. Mostly sunny skies return through Saturday with high temps in the low to mid 70s.
Have a wonderful week!
