The ensemble predictability of the January 2015 and 2016 East Coast winter storms is assessed, with model precipitation forecasts verified against observational datasets. Skill scores and reliability diagrams indicate that the large ensemble spread p

Two anomaly-based fields, raw anomaly (RA) and normalized anomaly (NA), have been proven to be useful to indicate different aspects of weather extremes compared to conventional total fields. Based on the previous studies and a case analysis of the Be

In June 2006, significant flooding and flash flooding impacted much of the mid-Atlantic region as a continuous supply of deep tropical moisture moved north from the subtropical Atlantic ahead of a slowmoving cold front. A 3-day period of heavy rain r

From 18 January to 23 January 2010, a series of winter storms impacted the western United States. During this period, a record-setting system produced severe convection, high winds, and heavy rain and snow on 21–22 January. The severe weather inclu

Forecasting winter storms in the northeastern United States during the 2008–2009 season was very challenging owing to large uncertainty in the numerical weather prediction guidance prior to each storm. Forecasts for the February 2009 post-Groundhog

Synoptic-scale weather events over the western United States are objectively ranked based on their associated tropospheric anomalies. Data from the NCEP 6-h reanalysis fields from 1948 to 2006 are compared to a 30-yr (1971–2000) reanalysis climatol

Forecasting major winter storms is a critical function for all weather services. Conventional model-derived fields from numerical weather prediction models most frequently utilized by operational forecasters, such as pressure level geopotential heigh
