Radar loop for the history books.

I spy a flood of condensation nuclei...

2/2 Note HCR development, indicating an already unstable boundary layer that is currently capped. With deeper moisture influx through the day and modest diabatic heating, this should mix out across northern LA/northeast TX/southern AR this evening.

[Brett Rossio @Rossiosonde]

Also, while our attention is turned to northwestern TX, OK, and KS. Do think folks in the Arklatex region should keep the weather radios close this eve. Agree with SPC in highlighting this area as there will be a belt of stronger mid-level southwesterly flow.#txwx #lawx #arwx 1/2

[Brett Rossio @Rossiosonde]

Uncontaminated elevated mixed layer emanating from the Sierra Madre into west TX/OK, moisture returns converging along the developing dryline, closed low ejecting eastward, across Arizona, and a deeply sheared environment. What could go wrong...

@ryans_wx @shawnmilrad I know this is an old thread, but I have a question. What chemical reaction (via shortwave radiation) occurs to activate this chlorine and/or produce it. I understand the disruptive nature Cl has on O3, but wondering how the chlorine arises out of UV radiation hitting PSCs.

[Brett Rossio @Rossiosonde]

In all the chaos going on right now, thought I'd at least mention this sneaky feature north of Hispaniola. Though highly sheared right now due to strong W to SW flow, deep convection over marginally warm water could yield some subtropical characteristics over next day or two...

[Brett Rossio @Rossiosonde]

Not a lot of time; getting ready for work. The airmass drifting into western KY, southern IL, and southeastern MO today has me concerned of a repeat of what happened last week in TN. I will try to give a bit more details in a little bit. #KYwx #ILwx #mowx

@Tylertheweather Technically, I’m off on Tuesday if I skipped to it 😉

[Brett Rossio @Rossiosonde]

Tomorrow is Friday the 13th, Sunday is the Ides of March; can I just skip to Tuesday and drink my bottle of Jameson?

[Brett Rossio @Rossiosonde]

@wxJeffDuda @CameronJNixon Looks like buoyant parcels only originating from ~800 hPa level. My guess is the bow echo was gliding along the stable BL with bowing elements enhanced by a rear inflow jet and hail growth supplemented by dry pockets aloft.

One of the greatest pleasures of coming back to Michigan is not having to contend with hills on my runs.

[Brett Rossio @Rossiosonde]

Gol-ly, this is crazy!

[Leigh Marts @ltmarts]

Figured @KATVToddYak would like this. Very cool snow storm track in Kansas.

[Brett Rossio @Rossiosonde]

Pretty incredible band of snow accumulation from the mesoscale snow banding yesterday! #kswx

@shawnmilrad The more I look at wxtwitter, the more I feel many METs had seniorities during their NWP classes.

We're saddened by the passing of celebrated #HiddenFigures mathematician Katherine Johnson. Today, we celebrate her 101 years of life and honor her legacy of excellence that broke down racial and social barriers: https://t.co/Tl3tsHAfYB

@ReedTimmerAccu @PaxBiggs And more radiosonde data! 😁 You��d get my vote!
