Heavy rain from the central Gulf Coast to Southeast U.S. this weekend

Heavy rain is expected from eastern Texas across the Lower Miss. Valley to the Southeast U.S. this weekend. This rain could lead to flash flooding. Meanwhile, heavy rain will also spread into the Northwest U.S., with heavy snow in the higher elevations of the Cascades and northern Rockies. Snow and hazardous travel conditions will impact the upper Midwest and parts of the Great Lake States. Read More >

An Arctic blast will arrive on Wednesday which will cause Thursday and Friday to be very cold. Winds on Thursday will cause it to feel much colder with wind chill values falling into the teens on Thursday morning. Friday morning will be even colder with temperatures possibly as cold as they've been in almost 2 years.
Everyone has received some rain this weekend. Rainfall totals from 7 am Friday through 7 am Sunday range from around a quarter of an inch to near 2 inches of rain. The highest rainfall totals so far are generally east of Interstate 35 and south of Interstate 20.

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:
