As Peter noted yesterday, ozone is code green across the US and is likely to stay that way until next April. Aerosols are only in the moderate range for the Appalachian states and there was an area of exported haze off NJ and NY seen in all satellites today. I have included an image from VIIRS this morning.
Two weather newsmakers are found today. In North Dakota, an early season snowstorm has dumped up to four feet (yes, feet) of snow in Lead, ND. In Spearfish, Meteorologist Thomas Patrick posted on Facebook this morning a photo of his door to his office. Not only is he furloughed and not able to be paid, he is stuck at work and can't get home.
In the Gulf of Mexico, Tropical Storm Karen is now really spinning up moisture and should make landfall later today in Louisiana. Glad I'm not there now. The image below is the color enhanced IR imagery showing very cold tops for the clouds. The storm should sideswipe the coast and head nearly due east to run down the Florida Panhandle. And thoughts of Karen adding a lot of moisture to the mid-Atlantic are fading. This evening NOAA downgraded the storm to a depression and winds will not be high enough to rate as a tropical storm. In Ohio, however, they are really struggling to get the President's Cup in with the amount of rain they have been having in Columbus, Ohio.
