Big change in today's ECMWF seasonal model forecast for ENSO: La Niña is back on! The ECMWF SEAS5 has been one of the most reluctant models to develop La Niña, but suddenly it has latched onto something. Will be interesting to see if the NMME and Copernicus models support this.

I am running out of words to describe how absurd August 2024 was in Svalbard. Reaching an average temperature of 11°C in August would have been unimaginable just a few years ago. This is totally bonkers.

Added fire danger risk re: possible thunderstorms esp. Sierra / NE CA and NW CA mountains. Note the NorCal ops outlook to Saturday. Thanks to the latest hot days/warm nights period, fuels too will be trending drier vs. a week ago (1/2) #CAwx 9/5/2024

Wildfires burning in eastern Lane & Douglas counties have become quite active today & are producing large smoke plumes, especially the 208 Fire. This smoke is blowing northward over the Cascades. Smoke is also producing hazy conditions over the Willamette Valley & Portland metro.

Portland Airport has hit 101°F as of 4pm! This ties the hottest temperature ever recorded so late in the summer season, which was 101°F on this date in 1944. This also ties 1944 for the latest 100°+ on record. 🔥

A record day for Phoenix. Sky Harbor had a high temperature of 116 degrees. That breaks the previous record for the date of 115 in 2020. Not only that, but it ties for hottest day ever in September (other day is 9/1/1950). And, it is the latest occurrence of 116 degrees. #azwx

In the Pacific Northwest, wildfires scorch lands and billow smoke into the atmosphere. In Oregon, the Rail Ridge Fire has grown to nearly 83,000 acres since it ignited on September 2nd.
