Severe Thunderstorms and Excessive Rainfall in the Southern Plains Today

Heavy to excessive rainfall may produce additional flash flooding today across parts of the southern Plains where the greatest risk is along the Red River Valley into western Arkansas. Scattered severe thunderstorms are possible today from north central Texas into the ArkLaTex Region. Large to very large hail, damaging winds, and tornadoes are all possible, with some strong-tornado potential. 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:
