Only the 6th tornado warning for Hawaii since 2002.

That little surprise tornado warning was in a bit of a rough environment but I can see why it rotated. Nice low level thermodynamics, managed to form as a discrete mode and not a junky mess which is to the west of it. There are more discrete cells forming off shore, curious if a waterspout fest like earlier this year is on route

@WesL Any idea when picture functionality will be restored? As of now trying to upload a pic causes the whole text box to lock up for like 45 seconds then spams a bunch of error messages. Something is super broken.

we need a fire weather thread

We do have one, it was just never picked up. Not sure how to link individual threads, but it's named "2025 wildfires".

bow echo with a lot of rotation areas in north new Brunswick Canada (moving east) and east Ontario Canada (moving south) right now , similar to yesterdays rotation areas.

 

[joshoctober16]

the images wont be sent .... theres a super tiny bookend vortex right now in eastern canada. wish they can fix this issue.

Soooooo I am watching this RANDOM video about 2011 and the 2025 EF5, and they mention @JPWX.

UPDATE: I didn’t know @JPWX had a street named after him. Well deserved

Hey guys! I got an email alert from eBay that there's another April 3, 1974 book available. I know some of you wanted a copy.

The SPC has outlined a D3 Marginal for the western California coast, mentioning "weakly rotating storms" indicating there likely will be a brief tornado risk with onshore squalls. The NAM has a actually alright environment given it's California in December. 225 0-1km SRH and 700 MLCAPE. A few brief tornadoes would easily be possible with convection. I wouldn't expect the mode to be poor, it could feature a few low topped, semi discrete cells coming onshore. Lapsw rates also are steep, with low level instability around 180 (NAM maybe overdoing). Regardless, this is a interesting risk and i certainly would expect a sneaky onshore Christmas Day tornado risk.

Temperature output on today's model runs for Tupelo and Aberdeen. Severe weather threat incoming late month (December 28th or so). Definitely so if the Canadian verifies.

Most recent late December (December 28th) severe weather outbreak was 2024. Otherwise, you have to go all the way back to 2010 to find the last severe weather threat in late December (December 31st).

The current Day 3 Marginal Risk in California says we need to look out farther east.

 

[JBishopwx]

Significant flooding threat out west Tuesday Night/Wednesday.

 

[WeathermanLeprechaun]

Environment continues to support a few tornadoes on Christmas Day in Western California, amidst marginal CAPE. More of a broken up line with isolated damaging wind included.

 

[WeathermanLeprechaun]

18z HRRR said a saturated yet broken line of mini supercells for W Cali. Personally think a 5% may be warranted as models seem to agree on this orientation. Very strong low level shear profiles and enough instability will be avaliable to support this. Few tornadoes certainly possible.
