Accumulating Snow For Portions of the Northeast into Tuesday; Heavy rain with Mountain Snow Possible For the West Coast Mid to Late Week

A weak storm system will track across the Northeast states overnight into Tuesday with several inches of accumulating snow expected from northern Pennsylvania into Southern Maine. A West Coast storm will bring several rounds of heavy to excessive rain and mountain snow to the region mid-to-late week. Mudslides and debris flows will be possible over and around California burn scars. 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:
