TYLER, TX (KTLV) - A strong cold front will be moving into East Texas Early Friday morning and along and ahead of this front, there is a chance of severe storms, including isolated tornadoes. The image above is of a forecast radar image for 7AM tomorrow morning (image here). Instead of seeing a straight line of storms we see more of a wavy pattern. This is called a line echo wave pattern and in many cases this type of storm system will produce very gusty winds and isolated tornadoes. Many East Texas tornadoes occur in patterns such as the one moving through East Texas tomorrow morning.
In addition to a slight risk of severe weather, heavy rain will be a concern. The amount of moisture available for thunderstorms is unusually high for this time of the year thanks to a strong southerly flow off the Gulf this afternoon. As the cold front moves into East Texas, it will force this warm moist air up and over the front producing widespread heavy rain behind the main line of storms. Some places, mainly north of I-20, could see 2 to 4 inches of rain tomorrow. The image below shows the storm total precipitation that is forecast(image here).
