In the meantime, enjoy an extraordinary fall week, with temperatures getting around 70F, no rain, and lots of sun. And the bite of crisp temperatures in the morning to ensure you feel invigorated and alive.
The temperatures during the past four weeks have been very close to normal, as shown by the plot below (red and blue lines are average highs and lows)
Precipitation has been a bit below normal during the same period (blue is normal, red observed), by roughly .7 inches.
Want to see something amazing? Here is the total precipitation predicted though Saturday at 5 AM (from the GFS model) Nothing along the U.S. West Coast-: WA is entirely dry. But the East Coast gets washed away. SE Alaska gets torrential rain as well.
The pattern producing this weather is really not exceptional (see upper level map below for tomorrow afternoon). A deep trough over the Gulf of Alaska is trenching Alaska, while a weak ridge is stationed over the western U.S. and Canada. A weak trough is off of our coast.
The National Weather Service forecast for the next four days is as close to ideal as imaginable (see below), with highs around 70 and lows near 50 (colder away from water). Sun. No rain.
Last night some of the cooler suburbs southeast of Seattle dropped into the mid-30s...and that was at 2-m above the surface. Some folks surely had frost. In contrast, the temperatures only dropped to the mid-50s at some locations near the water. (the 92 was probably a thermometer near someones grill). I am always amazed by our local contrast on cold, clear nights. 20F differences is not unusual...can get to 30-35F in the right situations.
This good weather won't last forever. The latest NAEFS North American ensemble forecast of many model predictions indicates more clouds and some rain by the second week of October (see below). So enjoy this pattern while you can.
