As of 1:55 PM, the freezing line is located along a line from Bonham to Mineral Wells to Comanche. North of this line, freezing rain and sleet continue. Road conditions have become very dangerous in these areas. Reports of tree branches and power lines down have also been received. To the south of this line, showers and a few thunderstorms continue. The heaviest rain is located along a line from Cleburne to Hamilton, where rain rates of one-quarter to one- half inch per hour can be expected. These moderately heavy rains will lead to ponding of water in low-lying areas.
It will remain cloudy and cold through this afternoon. Freezing rain is expected along and northwest of an Eastland to Gainesville line and either rain or freezing rain elsewhere along and northwest of a Goldthwaite to Denton to Bonham line. There will be showers and thunderstorms across the rest of North and Central Texas and heavy rain will lead to localized flooding. Highs will be in the upper 20s northwest to the mid 50s southeast. Expect north winds 15 to 20 mph.
The Ice Storm Warning has been extended and now includes Montague, Young, Jack, Wise, Stephens, Palo Pinto, Parker, and Eastland Counties, and is in effect until midnight tonight. Ice accumulations of up to one-half inch can be expected in these areas. These ice accumulations will lead to very dangerous travel conditions, as well as falling tree branches and isolated power outages. Travel is highly discouraged in these areas. Meanwhile, the Winter Weather Advisory has also been extended, and now includes Cooke, Grayson, Fannin, Denton, Comanche, Erath, Hood, and Somervell Counties. Ice accumulations of one-tenth to one-quarter inch can be expected in these areas, leading to hazardous travel conditions.
It will be cloudy and cold Thursday morning with a chance of rain or freezing rain along and northwest of a Goldthwaite to Sherman line. There will be a chance of rain elsewhere. Temperaturees will rise into the lower 30s northwest to the mid 40s southeast by midday. Some light ice accumulations will be possible in the areas where temperatures are below freezing.
A Flood Watch remains in effect along and east of a Gainesville to Mineral Wells to Killeen line where rainfall totals of 2 to 4 inches are expected with localized 6 inch amounts likely. Heavy rain will lead to flooding. Please exercise caution. Do not drive into water of unknown depth. Turn around. Don't drown.

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:
