5/18/20 - 5/23/20 Upper Low Flooding & Severe Threat

[SD]

Looks like it's set in now. Fetch of moisture off of the Atlantic developing into a band of rain, pointed this way. Solid rain rates now under a big layer of nimbostratus.

It actually rained hard here for a few minutes

Looking like there is going to be some real focus of banding and precip in central NC from all the short range guidance I’ve seen ... radar is going to be looking very interesting next day or so

The German model is a crush job.

I'm noticing the rain is somewhat heavier than you would think based on returns. Sometimes even under clear radars I have a small beady tropical type rain. Millions of tiny drops, heavier than a hard drizzle.

Lol this band is back building into Charlotte

You're telling me. Literally a firehose of heavy rain coming right over the metro. There are going to be some serious flood issues if this band persist.

3.17 total, this is just a straight-up weird event. Almost tropical storm-like squall lines (minus the wind), oh and its 50F on may 20th

There's going to be strong near-surface frontogenesis over the eastern piedmont & west-central coastal plain driven largely by strong low-level convergence at the edge of the CAD dome as it merges with a weak surface trough leftover from today's precipitation.

You can clearly see that here on the 3km NAM forecast, respectable NE winds of up to 15 knots over the north-central coastal plain decelerate to 7-10 m/s in the Pee Dee region of SC. This cause air to pile up (& rise) in between somewhere in the vicinity of the HWY 421 corridor (Wilmington-Fayetteville-Sanford, etc).

Radar rainfall estimates have surpassed 4" here, more than doubling our total from the previous 2 days in just a few hours

Btw, you can thank this rain for the very uncomfortable humidity we’re gonna feel this weekend

I am good with that as long as it brings higher chances of some late-day storms.

Wet snow this morning per Raysweather on Mount Mitchell. Rain is here now in Wilkes but I doubt it stays long. Maybe till 6 before clearing.

 

[BirdManDoomW]

So other than current band overhead i77 tonight shouldn’t be as heavy as originally expected. Just showery without heavy convection.

Every setup has to be a boundary setup doesn’t it, really don’t wanna have to chase
