Intense NATL low


Recommended Posts

There are actually TWO amazing cyclones in the N. Atl right now.

The first one is the one further north, analyzed at 937 mb per the 12Z ECMWF (and has supposedly deepened since then). The second, equally interesting cyclone (IMHO) is the one currently undergoing baroclinic transition to the south of the monster low which has DEEPENED BY 34 MB IN 12 HRS (991 to 957 mb)!

How could these affect CONUS weather?

93mph gust at Thule, Greenland this morning.

SPECI BGTL 120648Z AUTO 10049G81KT 1200 UP SCT120 01/M05 A2853 RMK AO2 PK WND 09081/0638

What's impressive is that Thule is in NW Greenland and is super-far removed from the gale center...must be katabatic winds.

Well they aren't too far removed from the first low that was moved northwestward to the west side of Baffin Bay around that ob time (6z). There was quite the pressure gradient (940s to 1010s) across the western part of the country. 850mb winds were 70-80kt so it looks like some strong llvl jet winds mixed down. There may have been some katabatic influence too, but I won't claim to be an arctic winds expert. :)
