A period of high-based convection to the east and northeast of Hawaii was producing occasional lighting on 3 June 2024, as shown in the animation above. LightningCast Probabilities plotted show values around 50%, and lightning is occurring. Note that the Flash Extent Density colorbar has been modified to have a... Read More
A WRF model run that includes assimilated Low-Earth-Orbit (LEO) satellite sounder data (fused with ABI data) is being evaluated at the Hazardous Weather Testbed (Blog posts from forecasters at HWT are here). On 20 May 2024, the PHS model output included convective development over the eastern Plains of Colorado, as... Read More
At the request of Pacific Region Headquarters, the LightningCast domain centered on American Samoa has increased. At 1840 UTC, the domain roughly doubled, as shown in the two screen shots below from the RealEarth site. The Red Box captures the size of the previous domain; note that at 1900 UTC the contours extend... Read More
