I believe it’s also no coincidence that a corridor of greater concentration of intense/violent tornadoes exists near the Arkansas River valley. Local terrain influence and channeling of backed, low level flow, especially if there’s a NW to SE oriented warm front. #arwx twitter.com/katvjames/stat…

Wait. Why is Twitter placing a baby Yoda emoji behind the #ElNiño hashtag?? I am here for it 🤣🤣🤣
Great post despite the distraction! 😆

An important marker in #ElNiño development, as the 3.4 value crosses the 0.5 threshold. Obviously we have a ways to go before the three-month averages officially reach #ElNiño status, but with lots of subsurface heat and WWBs coming, it's only a matter of time.

The NHC begins issuing routine "tropical weather outlooks" today for the Atlantic. The 2-day version is still available, but the 5-day version (which was introduced in 2015) has been replaced by a 7-day outlook this year. [1/3]

I've had happen to me whats about to happen to many people setting out on chasecastions this week though. I flew all the way from the Marshall Islands in late April 2018, only to spend nearly an entire week in Ames doing nothing, there was nothing to even consider chasing. (1/2)

Well hello there, tiny meteorologist - glad to have you on board. 🥹💜

In January, this brilliant young lady walked up to me at a party, stomped her foot and said, “tell me about the weather!”
I complied! 
Today, her mom sent me this: “Career Day at school.” 
She is 6. I was 6 when I decided I was going to be a Meteorologist.
LIFE MADE!

NHC has determined that a subtropical storm formed in the Atlantic basin off the northeastern U.S. coast in mid-January 2023, and it will be designated as the first cyclone of the 2023 Atlantic season with ID AL012023.

PLEASE RT. Hopefully seeing this early will make someone think twice later before blowing a stop sign, crossing a double-yellow, driving distracted or driving 100 mph.
🎯over Oklahoma. Chaser circus central.
There will always be more storms. It's not worth it.

GO ! The definition of a trailblazer. I am so PROUD to know her & so lucky to have had the pleasure of storm chasing w/her over the years!
She was also featured in the spot about rise of women in storm chasing.
Epitome of a bad@$$!

This is one of my favorite perspective factoids Phil has provided over the years.
We've reached the "handoff" time of year, shown nicely in the graph below.
One month away from the "official" start of the 2023 Atlantic #hurricane season.

Currently 0 named storms around the globe. We are entering the climatologically quietest part of the global tropical cyclone season - as the Southern Hemisphere passes the tropical cyclone torch to the Northern Hemisphere.

Largest hailstone on record for the state of Florida appears to be 4.5" which last occurred in 2007. h/t for the stat which I found when searching for this answer! Records for several other states here, if interested: ncei.noaa.gov/access/monitor
Quote Tweet
How does yesterday's hail event compare to other hail events?
Well, the 3" hail report from Sanford ties the record for the largest hailstone reported in our east central Florida counties, but record for the state of Florida remains 4.5". #flwx

Now that’s something we don’t see often…or pretty much ever. 30% hatched hail for a good chunk of the Florida peninsula.
Costly hailstorms have become somewhat commonplace across portions of I-35 corridor.
The I-4 corridor? Not so much.

While a lot of focus is on the Texas severe threat today (rightfully so), should not ignore the SUPER RARE significant hail threat for Florida today. Today's hail risk vs. hail climatology. This could be a major story later. #FLwx

Second highest crests on record expected at Lansing & McGregor and third highest at Guttenberg & Dubuque in Iowa. This will be comparable to the 2001 flood (or higher in spots) but under the historic flood of 1965.
