Chief Meteorologist Justin Stapleton‘s Daily Forecast Discussion:
On and off showers for most of the day this Tuesday as the trough of low pressure (think a big dip in the jetstream) is pooling chilly air across the Pacific Northwest. That allowed us to see everything from rain, mtn. snow, and even some soft ice pellets, or graupel. Tonight, more rain will fall, same as today, with showers and breaks throughout the night. Lows tonight will sit in the mid to low 40s.
The next two days will be fairly wet at the coast and inland valleys as back to back fronts will push through. Rainfall estimates are anywhere from 1-2″ in total at the coast and around an inch in the valleys. Winter weather advisories have been posted for the Northern Cascades, where close to 6″ of new snow may fall around the ski resorts level. Closer to the passes, travelers will see some icy conditions with 1-2″ of new snow to deal with. Highs will also be well below normal, only topping out in the mid 50s each day.
Friday also see plenty of showers, however by early Saturday, we might actually get about a 8 hour dry window as the next storm won’t arrive until Saturday evening. Sunday and Monday are back to showers but temperatures will be slowly rising back into the low 60s.
Have a great Tuesday night!
