Night Microphysics RGB imagery from the CSPP Geosphere site (link) show the blossoming of high clouds (deep red in the RGB) north of the Samoan Islands, clouds that subsequently sag southward. Careful inspection of the animation also shows clouds that are more pink than deep red; these are likely mid-level... Read More

GOES-19 is slated to become the next operational GOES-East in April. Despite being trained on GOES-16 data, CIMSS and NOAA scientists have been busy evaluating the AI lightning-prediction model, LightningCast, on GOES-19 output to prepare for the operational transition and see how adaptable the model is.Overall, the LightningCast output on...

As first hinted at in this blog post, the Community Satellite Processing Package for Geostationary Data (CSPP-Geo) (https://cimss.ssec.wisc.edu/csppgeo/ ) group at CIMSS has released a beta version of a unix-based package that computes LightningCast probabilities.  LightningCast (available online in real time for select regions) diagnoses the probability of a Geostationary Lightning Mapper (GLM) observation of lightning within...

A positively-tilted upper-level trough generated severe thunderstorms across the eastern U.S. recently. The associated surface low-pressure system with attendant cold front spawned numerous severe storms from Mississippi to Ohio to Virigina.The LightningCast model picked up on this developing convection, providing 10-30 minutes of lead time to lightning initiation in many...
