 DISCUSSION: As of July 5th, the NASA Sport satellite division issued the Beta Release of the Geostationary Lightning Mapper (GLM) regional, national, and global data frameworks. Attached below is an exact statement release from NASA SPoRT:
"The Geostationary Lightning Mapper (GLM) has completed a product validation review and has been cleared for distribution through the GOES-R Re-broadcast system. The GLM data are currently in a “beta-status”. This means that additional updates will occur with the data processing before GOES-R (now GOES-16) moves to the east position in November. However, this is a great opportunity to get an initial look at the GLM data in real-time. The two examples below show the first data to be received at 1454 UTC today (5 July 2017) over the eastern United States and for the GLM field of view. The data have been manually ingested into the National Weather Service’s Advanced Weather Interactive Processing System (AWIPS) display for demonstration purposes." As shown in the image above, you can see how there are also different types of lightning strikes which are observed and identified by the Geostationary Lightning Mapper (GLM). This reinforces the natural versatility of the GLM on-board technology in being able to further advance the capabilities of real-time lightning observations as well as lightning research.

DISCUSSION: As meteorologists working at the National Weather Service office in Portland, Maine geared up to prepare and deliver their first forecasts for the month of July, they quickly had quite a heavy workload to contend with. More specifically, a warm/moist air mass approaching portions of the interior Northeast on the final day of June set the stage for a convective threat across many parts of the interior Northeastern United States. As various favorable convective parameters came into place during the overnight and early morning hours on 1 July, there was increasing confidence for strong/severe thunderstorms to erupt during the late morning to early afternoon hours back on 1 July.
As noted above and as it would ultimately verify, severe thunderstorms kept the National Weather Service busy over the weekend, especially the NWS office in Portland Maine where a record number of tornado warning were issued on July 1st. You can see the storms evolution in this animation of GOES-16 satellite imagery. In the dual visible/infrared GOES-R satellite imagery loop attached above (as non-operational and preliminary data only), there were only subtle indications based on infrared cloud-top temperatures that there were severe thunderstorms developing at the time which would be capable of generating tornadoes in the near future. Despite the couple of tornadoes which did end up touching down, there fortunately were no recorded fatalities as a consequence of these severe storms which impacted portions of northern New Hampshire and western Maine.
