Flood Watch expanded, now includes Harris Co. and more through Memorial Day

HOUSTON, Texas (KTRK) -- A multi-day stormy weather pattern could bring the daily risk for street flooding across Southeast Texas though Memorial Day. The combination of daily rainfall plus a stormier pattern this weekend could lead to the potential for more widespread street flooding late Saturday, which is why we have an ABC13 Weather Watch for Saturday.

A Flood Watch is now in effect until 7 p.m. for most of Southeast Texas, Harris County included. 2-5 inches of additional rainfall is possible through Monday.

Should I cancel my outdoor plans?

Because these jet stream disturbances and storm complex are tricky to time out more than 24 hours in advance, it's wise to stay weather aware as you consider your plans for the holiday weekend ahead. We are not advising anyone to cancel plans, but we strongly recommend folks also have an indoor "plan B" option just in case your original plans get rained out. Currently the most likely timeframe for strong storms looks to be on Saturday afternoon and evening.

What weather should we prepare for Memorial Day weekend?

Scattered showers and thunderstorms are possible every day, so make sure that if you have outdoor plans you also have a place to run for cover should you cross paths with a heavy thunderstorm. When it is not raining, it will be warm and humid. We have highs in the low-to-mid 80s and lows in the upper 60s and low 70s all three days. An upper-low will spin up over Central Texas Saturday, sending a wave of heavy thunderstorms toward Southeast Texas sometime late Saturday and early Sunday. That is why we have a Weather Watch for Saturday due to the potential for street flooding, which could also be a concern for early Sunday. too. The good news is we are seeing signs the flood risk will decrease Sunday into Memorial Day, and we have dropped Monday's rain chances down to just 40%.

When will this storm pattern come to an end?

We will have lower rain chances both Memorial Day and Tuesday, but another upper-level storm is expected to swing through with a high chance of rain on Wednesday. After the middle of the week, we should turn hotter and drier for the final weekend of May.
