Discussion

The last signs of showers are drifting along the easternmost edge of Lake County early this morning. Widespread showers on Thursday brought roughly 0.5 to 0.75 inches of rainfall to areas east of the Cascades and over terrain in western Siskiyou County. The Scott, Shasta, and Rogue valleys got around 0.1 to 0.2 inches of rainfall, with a few hundredths reaching farther north. A dry cold front passes to the north today, which will keep temperatures cool across the area today. Daytime highs will see little change from Friday's, but clear skies tonight into Saturday morning will bring lower overnight lows. For the Umpqua Valley, this means frost conditions are expected early Saturday morning. Temperatures in other west side valleys could drop to near freezing while areas east of the Cascades look to be in the mid 20s to mid teens. With moisture lingering, low-lying areas may see areas of patchy fog on early Saturday morning as well.

A progressive patterns over the weekend with an upper ridge creeping towards the area. This will bring weekend highs back over seasonal norms by up to five degrees for west side valleys while the east side highs will stay closer to average. This warmth will be short- lived as current guidance shows a low pressure system approaching late Sunday and remaining over the area through much of Monday, bringing rainfall focused on west side areas as well as gusty winds over terrain and areas east of the Cascades. This next round of activity looks overall unimpactful in guidance, with coastal areas seeing 0.4 to 0.8 inches and inland areas seeing lower amounts and elevated winds staying safely below advisory levels.

Behind the low pressure system, flow aloft looks to be determined by a different system hovering over the Pacific Ocean and ridging over the southwestern United States. If the low has more influence, cool or seasonal temperatures continue. If the ridge can nudge the low farther west, temperatures may creep slightly above average. There is some uncertainty, with GFS ensembles showing a ~30% chance for additional rainfall during the week while the ECMWF ensemble shows drier outcomes. But even in the case for additional activity, significant impacts do not look likely during the week. -TAD
