Cool front blows in late Saturday, widespread rain expected Saturday night

HOUSTON, Texas (KTRK) -- Houston, we have a cool front! It's expected to arrive in the late afternoon, followed by a rainy night and cooler air for Sunday.

What's the outlook for this weekend's rain chances?

We start with a mostly dry morning, and rain chances build rapidly during the evening. Isolated showers are possible ahead of the front in the morning, then a broken line of showers and thunderstorms are expected when the front reaches your neighborhood in the afternoon. The cool front will reach Houston late Saturday afternoon likely sometime between 4 p.m. and 6 p.m. But it's behind the front when the rain chance really climbs with widespread showers continuing off and on through much of the night. We currently have Saturday's rain chance at 20% in the morning, up to 60% in the late afternoon, then climbing to 90% at night. A few showers could linger into Sunday morning, so we are keeping a 30% chance of rain in the forecast for the morning. The afternoon should be dry and pleasant everywhere.

How cool will it get behind this front?

Temperatures should dip into below-average territory behind the front. We expect a couple of days with highs in the 70s and a few mornings with lows in the 50s. The average high this time of year is around 80, and the average low is around 60.

What's the outlook for next week?

Monday should be nice and dry for most of the day, but light showers could spread in from the west toward the evening. Monday night we expect that disturbance to blow in from the west, pushing rain chances to at least 40% for Tuesday. This disturbance could keep rain c Another storm system looks to impact us the final weekend of April, with thunderstorm chances climbing for next Friday, Saturday, and Sunday.
