Thanks to NESDIS and the GOES-R Proving Ground, GOES-14 has been made available for super rapid scan operations for GOES-R (SRSOR) since February 1, 2016 and will run through February 25, 2016. This is allowing the Ocean Prediction Center (OPC), Weather Prediction Center (WPC), Tropical Analysis and Forecast Branch (TAFB) from the National Hurricane Center, and the NESDIS Satellite Analysis Branch (SAB) the opportunity to look at cool season convection, nor’easters (when they cooperate), along with interesting lake effect or mesoscale features. For this blog post, I’m going to focus on a few events that have affected the OPC during this past week.
Hurricane-force low off the southeast US coast that affected the “Anthem of the Seas” cruise ship from 02/07/16 – 02/09/16:
From February 7-9, 2016, a very strong storm formed off the southeast U.S. coast from a shortwave trough that split from the northern stream, dove southeast towards the Gulf Coast, then initiated a surface low pressure early on February 7th. This low rapidly intensified and was producing hurricane-force winds near the Royal Caribbean’s Anthem of the Seas by 0300 UTC on February 8th.

Mid-Atlantic Storm to Hurricane-force low on 02/09/16:
Another storm-force to hurricane-force low formed on the heels of the powerful ocean storm due to the anomalously strong upper trough on 02/09/16 and one of the OPC forecasters mentioned using the GOES-14 SRSOR for his analysis:
“HOWEVER THIS MORNINGS PASSES MISSED OUTER NT2 WATERS WHERE HIGHEST WINDS ASSOCIATED WITH DEVELOPING LOW WERE OCCURRING. BOTH THE 12Z GFS AND 12Z ECMWF ARE INITIALIZING TWO SURFACE LOWS OVER SOUTHEASTERN EDGE OF OUTER ZONES ANZ920 AND ANZ910. BASED ON THE ESTIMATED LOW POSITIONS FROM THE GOES 1 MIN SUPER RAPID SCAN IMAGERY TODAY…IT APPEARS THAT THE 12Z ECMWF HAS A BETTER 18Z POSITION AT LEAST WITH SECOND CENTER INVOF 37N70W AT 18Z. 12Z GFS IS ABOUT 1 TO 2 DEGREES NE OF ECMWF POSITION.” ~Clark

Strong thunderstorms in the OPC southern Offshore Zones on 02/12/16:
As a clipper storm strengthens near the North Carolina coast today, 02/12/16, strong thunderstorms have erupted near and east of the Gulf Stream.
This latest storm is progged to become a hurricane-force low as it moves to a position just southeast of Nova Scotia in the next 24 hours. It has surely been an impressive week for storms along and off the East Coast!
Thanks for reading!
Thanks Mr. Folmer! I’ve converted some of these gifs into HTML5 video and shared them on reddit here: https://www.reddit.com/r/radarloops/comments/45iyuw/lightning_strikes_within_12_februarys_clipper_off/
Thank you for the credit and for sharing with others! The animation from 2/9 is 2-min lightning density, but it looks like the first few time steps stuttered a bit, possibly giving the 5-min look. I apologize about that as I hadn’t noticed until I looked closer.
Thanks for the clarification, I’ve edited my comment there and on the other subreddits to which I posted that.
I’m trying to build up hype about GOES-R with the help of SRSOR data as well as Himawari-8 data (with some success!)
I always try to credit the sources when possible. Many of the animations I share come from the CIMSS Satellite Blog, which unfortunately doesn’t tell me the name of who is making the post (I think its usually Scott Bachmeier, but there’s another guy who posts too). So I end up just giving the link to the blog.
Anyway, thanks a lot for posting these animations and analyses, it’s endlessly fascinating to me. Kicked myself for years for studying geology instead of met.
