Basically, you want a good updraft so the raindrop gets cycled a few times and grows by colliding with other raindrops. In some cases it could also be melted hail.

Thanks. Would that updraft and recycling have to take place at a fairly low level? I was just thinking that a very large raindrop would likely split apart if it encountered a long period of air resistance.

Is the forecast high on wednesday of 71 legit? I feel like the cooler temps keep getting pushed back. Kinda like snowstorms in the winter, always day 3-4.

 

It's been there for several days now, and unlike every other day in the past 2+ weeks hasn't been getting bumped up a degree or two each day.  Really looking forward to this.  Hope it happens.

I would think so, too.  I would think you'd need low wind-shear also.  Seems that you encounter big drops in tropical-type conditions: pop-up types that move very slowly.

pretty healthy cell entering northwest Montgomery.   looks like it has a (small-sized) hail core

 

I saw that cell on RS, I liked how the cell disintegrated as it crossed 270 and then picked right back up into a storm with what looks like a hail core again once it passed it.
