#chswx notes: Unusual chill, April 13’s final tornado tally

/ May 9, 2020 at 9:03 AM
850mb temperatures and 500mb heights from a RAP13 model projection in May, I swear.

A relatively mild winter has one last trick up its sleeve as an unusually chilly airmass has descended from the Arctic onto the eastern half of the country. This brought Central Park in New York City only its second May 9 snow on record (first was in 1977) and has helped send numerous low temperatures to record levels all the way into Alabama and Mississippi.

A devastating day comes to a quiet end

Monday’s severe threat: Timing is everything

/ April 11, 2020 at 6:19 PM

What’s clear about Monday is that, at some point, there will be a squall line with strong thunderstorms coming through the area. These storms will be capable of producing wind damage and could spawn a tornado or two along the leading edge of the line.

The degree to which this threat will materialize is going to be highly dependent on timing, and that’s where it gets tricky — but I’ll do my best to demystify it.
