storm name "Marco" is on this year's list for the Atlantic. It would have been a huge coincidence if Marco and Polo were named storms at the same time.
Recent passes of Hurricane Polo show flight-level winds around 150kt and pressure values of 909mb or a bit less. The TropicalTidbits satellite view now has a 914mb pressure shown. (not sure if this is the official value)
The jet stream has broken down in to some strange patterns today, with a north flow over the Great Lakes, south flow over the Rocky Mountains, blocking high over Quebec
The NAM was not that accurate with a lot of precipitation for a long time. But you gotta love the severe weather soundings when it said 3000 J/kg when the GFS said 1500 J/kg.
