Heavy Rainfall Across the South Today; Midweek Coastal Storm for New England

Heavy rainfall and isolated strong to severe thunderstorms are forecast across parts of the South today with a stalled front across the region. Wednesday into Thursday, an area of low pressure will develop into a coastal storm and spread heavy rain, strong winds and coastal flooding from the Mid-Atlantic into the Northeast. The strong winds will also create hazardous seas off New England. 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:
