High pressure has shifted inland and thus so has the thermal trough which has ended the Chetco Effect in Brookings and is allowing the marine layer stratus to start to move up the coast. The coast will see a big change today with more fog and clouds, less sun and thus cooler temperatures. For inland areas the shift of the ridge and thermal trough means even warmer temperatures! Yesterday was the warmest day of the year so far in Medford and Roseburg tied the record high from 1926 of 75 degrees.
Two cold front will pass through this weekend, one late Saturday into Sunday and one Monday. The first front will be a dry front meaning no precipitation, just cooler temperatures and breezy conditions. The one on Monday has a bit more moisture so we could see showers at the coast into Douglas county, but expect areas further south and east to only see more clouds with breezes and another drop in temperatures. High pressure quickly returns Tuesday and we start to warm up again and see that sunshine return!
