ABC13 Weather Watch for strong storms tomorrow afternoon

HOUSTON, Texas (KTRK) -- Today's rainy weather will taper off this evening, but another round of rain is coming tomorrow as a warm front lifts through Southeast Texas. This time we are expecting scattered strong thunderstorms that could bring street flooding, gusty winds, and small hail. That's why we've declared an ABC13 Weather Watch for Wednesday afternoon.

Overnight we expect isolated showers to continue, but there will be significantly less rain on the radar than what we observed Tuesday. Widespread clouds are likely to persist and there could even be a touch of fog in spots. Temperatures will only drop a few degrees or hold steady in the mid 60s through the night as a warm front blows in from the Gulf. This warm front will bring unstable air back to Southeast Texas, increasing the chances for heavy thunderstorms once it warms up.

Isolated showers are possible for the morning drive, but as temperatures warm toward 80 in the early afternoon, those showers will start blossoming into stronger thunderstorms. We expect those thunderstorms to be clustered around Houston and surrounding suburbs. They will be capable of dropping a quick 1-3" of rain that could flood streets. Gusty downburst winds over 40 mph, small hail, and frequent lightning are also possible. This could make for a rough drive home from work and school in some parts of our region. Tornadoes are unlikely but cannot be 100% ruled out.

Because these storms will be partially driven by the heat of the day, we should see the storms dissipate pretty quickly after sunset, if not sooner. Sunset now occurs closer to 8PM. Your chance of getting rain at some point during the day is 70%.

How much longer will this rainy weather stick around?

After Wednesday, rain chances drop down into the 20-30% range for the rest of the week and the weekend.

What's the outlook for the weekend?

Temperatures will rise back into the mid-to-upper 80s by the weekend and so will the humidity. A few showers and storms are possible each day Friday through Sunday, but at this time the rain does not look to be widespread nor does it look to be severe. In fact, most of us will just have a rain-free, warm weekend.

Are there anymore cool fronts in the forecast?

We just might get another one late next week as we say goodbye to April and hello to May.
