Tornado and Flash Flood Watches issued for some with storm chances increasing Sunday night.

HOUSTON, Texas (KTRK) -- A Tornado Watch has been issued for Austin, Brazos, Burleson, Colorado, Grimes, Houston, Madison, Montgomery, Polk, San Jacinto, Trinity, Walker, Waller and Washington counties and is in effect until 11 p.m. Sunday. Thunderstorms capable of producing a few tornadoes, damaging wind gusts and scattered large hail are expected to move into Southeast Texas later in the afternoon and evening hours.

A Flash Flood Watch has been issued for the following counties: Brazos, Burleson, Grimes, Houston, Liberty, Madison, Montgomery, Polk, San Jacinto, Trinity, Walker. The Watch is set to expire at 10 A.M. on Monday. The city of Houston is not included in the Watch.

After a quiet Sunday, storms are beginning to develop this evening. Strong to severe thunderstorms are possible north and west of the city of Houston through 1 a.m. The main threats with these individual storms will be strong winds, hail and a tornado or two. Then those storms are expected to move south and east into Houston early Monday morning. and depending on when your morning commute is, these could impact you! A line of thunderstorms will move from north to south across Southeast Texas beginning from 3 to 8 a.m. and ending off the coast. Strong winds, small hail and heavy rain are the main threats with those early morning thunderstorms.

What's the latest on the potential for severe weather in Southeast Texas?

A Tornado Watch is in effect for several counties north of the city of Houston. Thunderstorms are in the forecast for both Sunday and Monday which could become strong to severe. Isolated showers and storms could develop later Sunday afternoon across Southeast Texas, including Houston. So if you have outdoor plans for Sunday, that's definitely something to take note of. And while we're not expecting those to become severe, some of the storms that develop later Sunday evening could. The best chance for that will be north of the city of Houston in our northern counties beginning as early as 7 or 8 p.m. Strong winds gusts, hail and heavy rain will be the primary threats. Then those storms will move from north to south across Southeast Texas, moving into Houston overnight. They'll likely weaken as they do, but some gusty winds, hail and heavy rainfall cant be ruled out. As for Monday, the remnants of those overnight storms will push towards the coast early in the morning. Then there's one more chance for a few scattered showers and storms alter in the day, but we're not expecting those to be severe at this point.

And after a stormy start to the week, what's next?

The final few days of April and first few of May are looking warm, humid and with the chance for a few showers and storms each day through Friday. This activity doesn't look to be organized severe weather, but a couple of showers and storms across Southeast Texas could develop each day of the work week.

Are there any more cool fronts coming ahead of summer?

We now have one penciled in for the first Friday of May! This front will bring a chance of thunderstorms when it blows in followed by a day or two of slightly lower humidity. It may not do much to drop our temperatures.
