Severe T-Storm Warning remains in effect for another 20 minutes or so for a portion of WBR, Iberville, and EBR Parishes. Pea to marble sized hail was reported with this storm in Plaquemine, LA. Damaging winds of 60 mph are also possible. Storm is moving to the NE at 45-50 mph.

Would you agree that central Mississippi, Alabama and into western GA are in for the worst?
Yes. Specifically southern central Mississippi in through Alabama.

Seattle and Portland are the same way. Just the forecast of snow creates a panic
Atalanta has zero snow equipment so an inch or two and the city comes to a stand still. When I lived there if snow was in the forecast I made sure I left work an hour before the precipitation moved in to get home.

Just curious, what is the reasoning behind this? Differential energy in the form of temperature, humidity...?

hail is being reported with this warned storm.
I just discovered "Hydrometeor classification" and it is now my favorite radar product because "hydrometeor" is an awesome word. It was definitely showing hail between the split and the bridge. Did anyone from around there see hail? I'm wondering how good this algorithm really is.

we all remember from the winter vortex in 2014

The algorithm is good enough for what it does. It takes several radar products and combines them to determine the type of precipitation at the particular tilt level. It isn't always what you will see on the ground cause it's reading at whatever height that tilt is at the time, so the farther you are from the radar site, the higher it's reading. Also in the event of winter weather it doesn't take into account refreezing so you may be seeing sleet, when it's showing rain. Typically the hybrind performs better in winter weather, but in severe weather, like today, I would say it's a wash between the two as they aren't totally accurate to ground truth, but an identifier of what precip could happen.

Cool. I'm guessing that the radar beam out of Slidell is a few thousand feet over Baton Rouge, even at the lowest tilt.

looks like BR is done until the big line of rain gets here

Just took a walk about outside and the clouds are moving at a pretty decent clip toward the N/NW. Low level jet has definitely picked up. We're getting into the window for severe stuff now for the BR -> River Parishes -> Northshore now.
Most concern though is the northern sections. Felicianas. Northern Tangipahoa.

I'm sitting on my front porch uptown nola and hearing the monkeys at the zoo a few hundred feet away going nuts right now. What's it like in areas between BR and NOLA right now?

Because during this round of storms this is where the most serious weather will be. Guessing stronger storms coming from Gulf versus the north...

Looks like the cells have moved out of the BR area now. Are you talking more about the line coming later?
