Welcome to our new "Severe Weather Potential Nowcast" product which will be
replacing the Mesoscale Discussion product. With this new product, we will be able to
show areas where severe thunderstorm development is most likely to occur
within the next several hours. This will be done using a locally run WRF-ARW model
simulation of Doppler radar reflectivity. The model will analyze current radar and
precipitation trends, then produces an echo simulation of future reflectivity echos
which are expected to occur. That allows us to "hone in" on areas where storms
should develop in the short term. The WRF-ARW model is one of a few convection
allowing models we use to predict short term storm development.
In addition, you will be able to overlay various parameters for a more detailed view
of the mesoscale situation. If a weather watch is being considered, this will be
highlighted in the text segment below the image animation. Notice: This product is considered "experimental", and may not always
be current. To send us feedback about this new product, simply
email us. We
will be accepting comments until July 30th, 2015. The additional overlay image options
are disabled at this time.
