Heat and Fire Weather Concerns in the West; Excessive Rainfall Possible in the South-Central U.S.

Heat will build over the Intermountain West and the Southwest the next couple of days. Lightning from dry thunderstorms can create new fire starts and combined with gusty winds may cause a fire to rapidly grow in Oregon and northern California. Flash flooding will be possible in Arizona and west Texas today, as well as parts of the southern and central Plains due to slow moving thunderstorms. 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:
