Published by the National Weather Association, the Journal of Operational Meteorology (JOM) covers topics relevant to all aspects of operational meteorology on a range of time and space scales. Suitable topics include new or improved forecasting and warning techniques, verification studies, applications of observations and models to improve forecasts and warnings, and case studies of major weather events. Climatological studies, interdisciplinary studies, and studies documenting education and training practices also will be considered if relevant to operational meteorology. In addition, the Editors welcome submissions that present strategies for the creation and dissemination of forecasts and warnings that maximize the protection of life and property. JOM is a peer-reviewed, all-electronic journal with an international scope, providing authors with the benefits of economical publication costs and rapid publication following acceptance.
Note: effective 1/1/2016, the JOM has transitioned to an open access journal. As such, all articles, past and present, are now available to all free of charge.

Utilizing Crowd-Sourced Rainfall and Flood Impact Information to Improve the Analysis of the North Central Gulf Coast Flood Event of April 2014In late April 2014, a slow-moving cold front exiting the central plains produced a large area of showers and embedded thunderstorms across the southeastern United States. In the lower Mississippi Valley, a line of heavy thunderstorms initially developed the evening of 28 April 2014 with subsequent thunderstorm outbreaks for the next two evenings centered on residual thunderstorm outflow boundaries. This Continue Reading...
- The National Weather Service (NWS) is charged with the responsibility of issuing severe weather warnings for the public whenever life and property may be in danger. During severe convective events, the NWS issues severe thunderstorm, tornado, and flash flood warnings. This study solely examines severe thunderstorm and tornado warnings conveying threats for wind, hail, and tornadoes. Continued...
Impacts to Aviation Weather Center Operations Using Total Lightning Observations from the Pseudo-GLMThe Aviation Weather Center (AWC) is responsible for delivering accurate, consistent, and timely weather information for safe and efficient flight across the United States airspace system along with international obligations. One of the key concerns for forecasters is the prediction and monitoring of convection which directly affects air routes as well as ground operations. Lightning observations are a vital component of available observations helping to confirm the presence of convection and verify forecasts. Up to this time the AWC has relied solely on ground-based cloud-to-ground only detection networks. With the upcoming launch of the Geostationary Lightning Mapper (GLM) aboard GOES-R, the AWC has the opportunity to expand the use of lightning observations by observing total lightning (i.e., the combination of both cloud-to-ground and intra-cloud observations). AWC and NASA’s Short-term Prediction Research and Transition Center (SPoRT) have collaborated to assess a demonstration GLM product, the pseudo-GLM, derived from ground-based lightning mapping arrays. This collaboration has focused on the utility of using total lightning in aviation weather forecasting in preparation for the GLM instrument. This paper presents several small cases identified by forecasters using the pseudo-GLM data in operations and discusses the role of GLM data in the future....
