    The Snoqualmie River at the Falls crested around 9 a.m. Tuesday with a water flow of 44,920 cubic feet per second. This was the greatest flow recorded at Snoqualmie Falls since Dec. 9, 2015 and the 13th-greatest flow on record.

    The rain has ended, save for some drizzle in the central Sound. Rainfall in the mountains ended early today with the flood wave quickly running through the river systems. As this was a quick shot of very heavy rain along the headwaters and tributaries and not a multi-day rain event, rivers will pretty quickly fall below flood stage late tonight and Wednesday.

    Some fog and low clouds can be expected early Wednesday with some afternoon sunshine. Temperatures will be near normal -- with highs in the upper 50s.

    On Thursday, we'll be warmer with a bit more sun after morning clouds and fog with high temperatures in the 60s.

    A weak disturbance moving across the area Friday will bring a few more clouds and a few showers as well. Most lowland locations will receive little to no rainfall and snow levels in the mountains will continue to be above pass levels. We'll stay mild with a daytime high in the 60s.

    Colder air will drop south for the weekend but this will be a dry airmass, so after some early-day clouds, we'll have some sunshine each day with highs only in the low-to-mid 50s. Morning lows will be in the 30s to low 40s, so some frost on the pumpkin.

    We'll continue to be dry and a little cooler than normal with a mix of clouds and sun for most or all of next week, including Halloween.  Following this Friday's rain chance, the next decent chance for precipitation looks to be around next weekend -- the first weekend of November.
