DETROIT – Welcome to Saturday, Motown.

Summer-like warmth and humidity return this weekend with a chance of stormy weather during the first half. Temperatures rise and the humidity rises. This will mean increased instability and the chance of showers and thunderstorms. They will be widely scattered at first. Then a more organized storm line develops ahead of a front later today and this evening. Sunnier skies prevail tomorrow with even higher temperatures under intense sunshine.

Saturday morning will be warm and humid. Temperatures start in the middle and upper 60s. A few spotty showers with some thunder and lightning are possible from the pre-dawn hours through breakfast time. Stay on guard for wet roads and lightning.

Sunrise is at 6:18 a.m.

Midday temperatures climb quickly to near and just above 80 degrees under partly sunny skies. Humidity will be even more noticeable with heat indices in the middle 80s.

Remember to drink plenty of water, wear light and loose-fitting clothes and stay near or in air conditioned areas to remain cool and comfortable. Keep children and pets away from any empty vehicles.

Saturday afternoon will be hotter with highs in the middle 80s. The sauna-like feel will have your body feel like it’s 90 degrees outdoors. The unstable air will produce scattered showers and thunderstorms between 3 p.m. and 5 p.m.

The National Weather Service has a slight risk of strong to severe storms with heavy downpours, frequent lightning and damaging wind and hail this afternoon and evening.

By 5 p.m. and until 11 p.m. a more organized line of showers and thunderstorms will form and sweep across the region from the northwest to the southeast. Temperatures will fall to the rain-cooled 70s when wetness and nastiness arrive. Remember to dash indoors and stop swimming immediately after hearing thunder or seeing lightning. Also, if the power goes out, keep generators outside and far away from the house to avoid dangerous carbon monoxide.

Sunset is at 9:01 p.m.

Scattered showers and storms linger, Saturday night. Overnight lows will be near 70 degrees.

Sunday will be a bit wet in the morning. The second half of the day will be brighter and even hotter. Afternoon temperatures reach 90 degrees. Even with more tolerable humidity, remember to take care in the heat and put on sunblock before going outdoors.
