    I am reminded this evening, that 31 Dec 2017 came and passed without N0R and friends being terminated. Anybody know what the updated TIN/SCN is now? I see this is still present on the NWS SCN/TIN website

    I forecast big celebration at HQ if they are ever able to shut off low res NEXRAD L3 prods. The history of announced termination dates.

    Many cities in the Plains & Midwest saw their biggest jump in monthly average temperature from April to May on record. I listed a handful of cities organized from biggest temperature jump from April to May. Some prior records were from over a century ago & easily broken.

    Cleaning up my office, I found this gem circa 2002 and very much still relevant today. It was given at a Baron Weather conference and impacted me greatly as I continue to effort engaging the NWS to fix product issues. 16 years later and no sign of finishing yet :)

    Most frequent Severe Thunderstorm and Tornado Warning storm motion. based on issuance motion tag, binned every 5 degrees, this is the direction the storm is travelling from, not toward.
