The ridge of high pressure that we’ve been under starting last week is finally starting to break down as a low pressure storm system moves in from the Northwest. A cold front associated with this system will usher in rains, snow and winds. Sunday will be the last day of dry weather before this system. Increasing clouds and warm weather will continue through Sunday. The cold front is slated to move through Sunday evening. Before passage, winds will start to pick up near the coast and in the upper elevations. A HIGH SURF ADVISORY will go into effect Sunday morning at 11 and last until 11 p.m for Coos and Curry Counties. High winds will increase surf conditions late Sunday morning. The greatest hazard for surf zones and jetties will be during high tide. A WIND ADVISORY will go into effect starting Sunday around 2 p.m. and last until Monday morning at 5. This advisory is in effect for East Klamath, Lake, and Modoc Counties. Sustained winds in these areas will range from 25-35 mph and gusts could reach as high as 45 mph. High profile vehicles traveling along Hwy. 31 could be affected.
Rain will begin falling late Sunday night before frontal passage. The coast and valleys will see the heaviest rain, sometime around 10 p.m. on Sunday. All other areas will see shower activity into early Monday. The front should pass around 12 a.m. Monday morning, snow levels will then drop to around 3,500′. The lingering precipitation will then transition to snow near and above this level. Precipitation will last throughout the area until late Monday morning. Very little snow accumulation is expected, however driving conditions will deteriorate as more snow falls.
High pressure will start to build into the area late Monday and partly cloudy skies will continue through Thursday. A weak disturbance will move in, bringing another chance for shower activity on the first day of Spring.
Thanks for logging on and enjoy the weather!
