A convective system over Texas spawned a Mesoscale Convective Vortex (MCV) during the day on 2 June, as shown in the 1.5-day loop above (color-enhanced GOES-13 11-micron imagery shown every 12 hours). The convection along the dryline at 0615 UTC on 2 June evolved into the MCV shown at 1815... Read More
On yet another relatively rare SPC “High Risk” Convective Outlook day, a major outbreak of damaging tornadoes occurred across parts of Oklahoma and Kansas on 10 May 2010 (see: SPC storm reports | NWS Norman OK | NWS Witchita KS). McIDAS images of the GOES-13 0.63 µm visible channel data (above) showed the development of numerous long-track supercell thunderstorms across the southern... Read More
Spring convection and associated severe weather returned to the southern Plains on April 22nd. Did predictors of convection do a good job in locating the severe cells?CIMSS has recently started to produce synthetic satellite imagery from the Weather Research and Forecasting (WRF) model run at the National Severe Storms Laboratory...

Early morning visible imagery shows a region of modest convection developing into an arc in the Gulf of Mexico south of Louisiana. Radar imagery at 11 UTC shows a concentrated region of strong convection in the marine environment. Which satellite data can be used to identify the regions most at risk for convection in...
