Today we have a very strong front corridor, with a very fierce cold front.
For example, this is an image from the Langley Hill radar (near Hoquiam) at 5pm. Arrows point to intensity cold rain band ahead, with red signaling torrential rain! Such fierce fronts would break into ripples like waves.
Amazingly, high-resolution weather models were able to predict this feature, but a bit too quickly (see forecast at 3pm). Weather patterns have come a long way.
The National Weather Service is worried about this cold snap so they have issued a flash flood warning for the southern Sound region (see below).
Rainfall over the past 24 hours has been substantial, with some locations reaching more than an inch.
Wildfire season in western Washington is over.
And yes, there’s a lot more to come in the coming week.
What’s interesting is that our rainfall for the year is almost completely normal in western Washington.
This is a graph of cumulative precipitation since January 1 at Sea-Tac, with the green line showing this year’s total and the brown line showing the climate values. Wet spring balances dry summer/early autumn.
Similar to Hoquiam
Interestingly, the eastern slopes are higher than normal; (see Wenatchee below). Not only is the spring wet, but there is also normal rainfall in the summer.

Expectations will continue to cool down next week, with some days failing to break above the 40-year high. What an amazing change from a week ago
