ATL: ALBERTO - Post-Tropical

[tarheelprogrammer]

COnvection is on the increase around the center now. but most notably convection increasing in the "dry slot" to the east and south. looks like the low to mid level moisture is winning over.

and the center has wobbled and or drifted nearly due west of the advisory ..

What about the west side now?

The dry slot has rotated into the west side of the circulation and will eventually be evacuated out of the system.

[cycloneye]

Winds over the 50's at flight level.

[bella_may]

Hopefully the NHC didn’t pull the trigger too soon with dropping the watches...

[Javlin]

Gone as about as far W he will get according to the WV all out flat to the west.

https://atmos.washington.edu/~ovens/loo ... nhanced+24

[MGC]

Still looks like Alberto is moving NW to me.....dry air is eating the cyclone alive though....MGC

[cycloneye]

SFMR 50 kts wind is legit.

[Dean4Storms]

Recon on the NW leg in finding 50kt SFMR and over 50kts Flight Leve.... At least still a 50mph storm.

[stormhunter7]

agree, think the wind field expanded this evening?

[tropicwatch]

Hopefully they will wait for the vortex message before putting out the next advisory.

[cycloneye]

[cycloneye]

991 mbs the lowest pressure.

[Dean4Storms]

Long range radar out of Eglin showing some yellow and orange convection returns just NE of the center. First I've seen that strong a return in hours.

[Dean4Storms]

992MB?

[chaser1]

Not happening it's mostly dead Jim. Unless it stalls for a lengthy time. Enjoying the sun and nice strong winds on Clearwater Beach

I can't find a single trustworthy 12z and now 18z model that doesn't either strengthen it or maintain it to landfall.

I trust a few sources... climotology, living here forever and radar. Be happy to bet you a beer on it. Doubt it will lstrngthen unless it stalls for awhile. Lotta dry air and alot of tightening it would have to do.

Hmm, I can't speak for Aric but I think I'll take that bet. None of that tinny can light beer though, let's at least make it some decent craft beer lol! Should we base the bet on a 10 mph increase wind speed, or perhaps a 3 mb drop in pressure?

[cycloneye]

There is the center.

[cycloneye]

Here is the center.

Here is the shortwave IR for the overnight.

[Ed_2001]

4mb drop since the last recon passage. Now we wait for the dropsonde data to confirm it.

Edit: 2mb drop (992) according to dropsonde.
