Good insights from a great meteorologist and Disney fan!
Southern CA just experienced one of its wettest mid-November periods on record, and Phoenix is having a welcome wet start to the cool season. Also talking about some flash flood and severe weather risk next couple of days. open.substack.com/pub/balanced...
Looking at a record wet mid-November for parts of the Southwest, while record warmth persists in the Southeast
Some flash flood and severe weather risk early next week in the south central US, plus a look at Thanksgiving travel weather

An interesting weather event in the western United States. Not at all unheard of, but interesting!
Moisture from the remnants of Tropical Storm Mario move over California, leading to thunderstorms and heavy rainfall across the state.

From @agnes1972.bsky.social on his X account: "With Erin, the last ten years have now seen 11 category five Atlantic hurricanes. This puts us even further ahead of 2007, which held the previous record of nine. Remarkable."

Just 24 hours ago, #Erin was just a 65kt Category 1 hurricane. Now, after explosive intensification, it's increased 75kt to 140kt! Cool to see the structure improve, then completely bomb out

#Hurricane #Erin has just become a Category 5 hurricane (140 kt / 917 mb).
Earliest known occurrence of Cat 5 in open Atlantic (outside Caribbean & Gulf).
Rapid Intensification (+75 kt in 24h!)

A July hurricane-force non-tropical low near Greenland on July 11, 2025.
Central pressure fell into the low to mid 960s. At least 5 July — including all warm season months — records were set by the storm.
From Thule/Pituffik Space Force Base in Greenland, who broke their July record by 15 hPa.

The June heat across Europe was the worst on record due to an intense persistent heat dome - a blocked upper level pattern - which are becoming more common this time of year due to global warming. Europe is a ground zero for these. Heat index numbers reached 48C (118F). 1/

Alan Gerard has started a substack that I find very useful. Here is the latest: high temperatures 15 degrees above normal in the US midwest and Canada. Details below!
An amazing tail event is occurring in the upper Midwest and southern Canada with record temps being broken by 15 deg. If this were happening in summer it would be a big problem and we need to be aware that these events are increasing in likelihood. Read more here. open.substack.com/pub/balanced...

This is really really unusual!
An unusual setup could lead to significant hail along the I-5 corridor between Seattle, Portland, and Eugene on Wednesday.
Forecasters warn the strongest storms could produce hailstones the size of a hen egg (2.00" in diameter) or larger.

Agreed: a low pressure center THIS deep in THIS location is not at all common. That the forecast of it is relatively confident 6-days in advance is also uncommon.
Don't think I have ever seen anything like this in this portion of the country from an ensemble 6 days out before.
