Slow moving cool front keeps rain in the Houston forecast

Usually when you see a cool front on the weather map, it's moving fairly quickly. Not so this week.

The cool front sitting across Texas right now is parallel with the jet stream winds in the upper atmosphere so it's barely moving. Furthermore, a deep low pressure in the upper atmosphere over New Mexico is also sending out small disturbances which move along the front and keep it active with periods of rain and thunderstorms.

One round of severe weather moved across southeast Texas early Wednesday. Trees were knocked down in Burleson, Walker and San Jacinto counties. Heavy rain got as far south as northern Harris County, but most of the city and those cities south of I-10 got only light rain, if even that.

Because of this slow moving front, there's still a chance of severe thunderstorms on Thursday. Heavy rain and large hail are likely. There's also the slight risk of a few funnel clouds.  Most of the computer models are forecasting drier conditions for Friday. Our exclusive FutureTrack still shows additional rain in the area of Friday. So the ABC13 forecast calls for a 40% chance of leftover thundershowers.
