After a handful of late summer days, fall has finally set in. Temperatures stayed in the mid 60s for both Saturday and Sunday. We managed to pick up a quarter of an inch of rain over the weekend, with more to come today.
The rain we’re seeing is all ahead of a cold front that is making its way across the state. The heaviest rain is right before the passage of the front.
This front will be east of the Cascades by this afternoon, which means the rain we’re seeing will transition to showers for the second half of the day.
Tuesday we’ll get a break from the rain for a few hours, although it will still be cloudy, cold and windy.
Tuesday night the next storm moves in. Ahead of the storm we’ll see some strong winds, especially along the southern coast, where winds will be from the south, up to about 60 mph. The National Weather Service has issued a high wind watch for this event.
As this second cold front moves in, the rain will return Tuesday night for all of us and continue through Wednesday.
Behind the front, some especially cold air will move in. This will drop our high temperatures in the valley into just the low 60s and upper 50s for Wednesday and Thursday.
In the Cascades, the freezing level will drop to about 5,000 feet Wednesday morning and 4,500 feet by Wednesday night, allowing snow to fall at the passes for the first time this season.
By the end of the week we’ll be out of the woods as the jet stream lifts back to the north. We’ll be under zonal flow – which means no ridge or trough, generally mild, dry and slightly warmer with highs in the mid 60s.
