Excessive Heat for the Central and Eastern U.S.; Severe Weather from the Plain into the Great Lakes

Excessive heat will affect the center and eastern portions of our country today with numerous record highs are expected. The combination of heat and humidity, along and ahead of cold front, will focus showers and thunderstorms. Storms could be severe from the western High Plains, Midwest into the Great Lakes region; Locally heavy rainfall may result in isolated instances of flash flooding. Read More >

Experimental Convective Parameters For North Texas

The National Weather Service in Fort Worth is now offering Experimental Convective Parameters on this website!

The analysis is computed using surface observation data and the latest RUC model for all upper level data.  This is different from the SPC mesoanalysis web page, because no model analysis is used for the surface fields.  This means our analysis is heavily weighted to the latest surface observation. Thus, some small "bulls-eye" type areas may occur if a surface observation is outlying or incorrect.  Bad observations are periodically quality controlled by forecasters and removed.  The advantage to this technique is that our convective parameters will have a higher resolution and be capable of rapid adjustments if the atmosphere is rapidly changing.

The parameters are generated hourly, with the generation process starting around 15 minutes past the hour. The images should be available by 20 past each hour.

We are currently producing the following images:
