Skies will continue to clear tonight which will allow temperatures to drop quickly by Wednesday morning. A Frost Advisory has been issued for west side valleys for temperatures dropping to the mid-30s in the colder spots of the Rogue Valley, Illinois Valley and the Umpqua Basin. Medford will likely stay in the upper-30s, but the coldest spots of west side valleys will drop anywhere from 33 to 36 degrees. Precautions should be taken to protect sensitive vegetation.
Wednesday afternoon will be the warmest and sunniest of the work week as rain returns Thursday. A warm front will bring showers to the coast early Thursday, but a potent cold front will push inland Thursday afternoon and evening bringing moderate to heavy rain. The heaviest rain will fall along and west of the Cascades but we could even see some moderate showers on the east side before the day is done. Showers will continue Friday, with most activity at the coast and in the Cascades and lighter more isolated showers elsewhere.
Weather models have not come into agreement with the weekend forecast though at this time I am going with a chance to slight chance for showers on Saturday and drier conditions on Sunday. Either way warmer temperatures arrive Sunday into next week bringing mid-80s back to west side valleys and mid-70s to the east side. I hope weather models come into better agreement over the next couple days about the weekend rain chances.
Thanks for logging on and have a great evening!
