METEOROLOGIST MARISA WOLOSZYN’S FORECAST DISCUSSION:
Saturday was the warmest day, thus far, in 2013; high temperatures were in the low to mid 80s for the valley, Umpqua and along the coast. Clear skies after sunset and overnight will allow temps to fall into the mid 40s by Sunday morning.
Sunday will be warmer than Saturday, except for along the coast. High temps in the valley and Umpqua will be in the mid 80s; along the coast highs will be near 70 degrees. High, thin cirrus clouds will move in Sunday afternoon as an upper level low slides into northern California. This low will also provide enough energy + daytime heating to spark a few thunderstorms in the Umpqua Basin and the Cascades by late afternoon.
The low will continue to spin in northern California Monday through Wednesday, keeping a similar weather pattern each day. Partly sunny skies will start off each morning and high temps will climb 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 and warms up towards the end of the week.
Have a sizzling Sunday!
