Deep South Winter 2024-2025-2026

The 18Z GFS shows low pressure over upper midwest "starving" the cold air flow south. Wasn't there in the 12Z. It still has the gulf low (994 mb approaching FL) and it starts out as snow but ends as cold rain for the central gulf coast. It also has the gulf low a little further north, which doesn't help. That being said, it does dump up to a foot of snow before the rain sets in.

One thing looks more and more certain; there will be a gulf low next weekend, all models are showing it. What happens after than is still a guessing game.

Yeah. Seeing insane levels of snow on 18z is bonkers

Speed of interaction with that GOM low also playing a role here.

For reference, wasn't the 1993 "Storm of the Century" 991 mbs before crossing FL? 994 could be a pretty big deal if it verifies.

<edit> Actually, it shows 991 in the Gulf just north of Tampa, short of the 976 mb Tallahassee had in 1993. But, this shows it deepening to 959 mbs off the NE coast, which would eclipse the lowest pressure of 960 in 1993 recorded in New England, although off the coast. So, not a Superstorm, just another bomb Noreaster.

18Z run has the blizzard of the century for Boston and probably points north as the low tracks over Cape Cod Feb 2nd.

GFS goes north, Canadian goes south.
