METAR Import Problems Affecting TAF Verification

METAR Import Problems Affecting TAF Verification


The automated import of METAR data for TAF verification has experienced problems since April 2, 2017 and we are troubleshooting the issue.   In the meantime, we have been manually importing METARs--a time consuming process.  To date, April 6, 9, and 10  are available and TAF verification is complete.  We continue to import data for other dates as time permits.  We are sorry for the inconvenience and appreciate your patience.  We will notify you when we have an estimate of when normal TAF verification operations will resume.

The Historic Nor’easter of January 2016

NWS Releases The Historic Nor’easter of January 2016


A historic blizzard affected much of the Northeast and Mid-Atlantic states from January   22–24, 2016.  Over 100 million people were affected by the historic Nor’easter that dumped widespread 2¬–3 foot snowfall accumulations across the region.  The snow was accompanied by winds in excess of 35 mph creating blizzard conditions over much of the area.  The combination of wind and very heavy snow created major impacts to travel, closed many major airports, and stranded hundreds of motorists on roads.

The historic Nor’easter also led to significant coastal flooding along portions of the Mid-Atlantic and northeast seaboard.  Numerous roads, homes, and businesses along the New Jersey and Delaware coasts were flooded and emergency personnel conducted numerous water rescues.  The coastal flooding along the southern portion of the Jersey shore exceeded that experienced in the area during Hurricane Sandy in October 2012.

Because of the significant impacts of the event, the National Weather Service formed a service assessment team to evaluate its performance before and during the historic Nor’easter.
