On November 8th, we hit 70F, the latest 70F day so late in the season for Seattle.
This month Seattle has experienced 8 days with temperatures of 60F or more, a record. To illustrate our torrid conditions, here are the temperatures for the past two weeks at Seattle, with normal highs and lows. Amazingly, the daily lows have approximately the normal daily highs. Only two days in the last two weeks have had low temperatures near normal.
As shown below, a number of days have equalled or exceeded daily records (shown by short red and blue lines for high and low records).
There a lot of folks that are interested in the BLOB, the warm water feature that has been off our coast. But you can't blame the BLOB for our warm period. Why? Because the BLOB is dead. Deceased. Finished.
Want the proof? Here is the sea surface temperature anomaly (difference from normal) yesterday. See all that blue off our coast? Colder than normal water. No BLOB. What killed it? Low pressure centers and stormy conditions over the NE Pacific.
Here is a similar graphic for roughly two months ago. Healthy BLOB. You can see the difference.
Finally, with warm air aloft and long nights for surface cooling, low-level temperature inversions and fog have been forming overnight. Take a look at the spectacular scene from the Space Needle Cam this morning....very beautiful.
