What a nice surprise that was.

What a nice surprise that was.
The incoming shortwave over the Southeast will help to supercharge the poleward outflow of #Melissa over the next several hours. This may also promote additional deepening via extreme divergence aloft.

Somehow...the eye of #Melissa continues to warm. This indicates the presence of extreme subsidence which is often a sign of further deepening.
There's a legitimate chance we get below 900mb at some point overnight

We're very lucky to have such brave men and women putting their lives on the line to collect extremely valuable data with #Melissa.
Our satellite estimates have been running much higher than what recon has actually been finding.

We may actually have a few solid chances at severe weather in the Northeast next week if we can get a solid EML to spill over the top of this ridge.

Yesterday's 30% tornado risk from the SPC already verified (obviously) and the surveys haven't even started.
Their incredible efforts and advanced lead time undoubtedly saved lives.

Both today and tomorrow have the potential to be one of the most dangerous back-to-back severe weather outbreaks we've seen in years for the CONUS.

I know it's already been beaten to death on the other platform but a 5 (?!) Sigma 500mb jet nosing into anomalously steep lapse rates and deep moisture from the Gulf / Caribbean is certainly less than ideal for the Southeast.
