Metro Detroit weather: Wet, windy and warm Wednesday

Highs should reach 70s again Wednesday

Weather is all about perspective, so I want to begin with a reminder that today’s average high is 49 degrees -- and many of us are starting our Wednesday warmer than that.

We will have some scattered showers cross the area Wednesday morning, and then skies become partly cloudy. That incoming sunshine will boost our temperatures, which then causes more parcels of air to rise, which then causes a greater mixing of the lower atmosphere. That mixing will bring down some stronger wind from aloft, so gusts from the south or southwest at 30 to 40 mph are certainly attainable.

The warmer air -- highs should once again hit 70 degrees Wednesday -- will also make the atmosphere more unstable, so some scattered late afternoon showers and thunderstorms are also possible. Not everybody will get one, but the risk will be there. And remember that thunderstorms also pull down some of the stronger wind to the surface, so any thunderstorm could be a gusty one.

Wednesday’s sunrise is at 7:29 a.m., sunset is at 7:50 p.m.

It becomes partly cloudy Wednesday night, with lows in the mid to upper 40s. Southwest wind settles down to 8 to 12 mph.

Sirens will sound Wednesday

Just a reminder that this is Michigan Severe Weather Awareness Week, and there will be a statewide test tornado warning at 1 p.m. Most communities will sound their sirens at that time. When you hear those sirens, just pause for a moment and think about where you would go for safety should you hear that siren during a true severe weather event.

The rest of the week

Even if we start our Thursday with some sunshine, clouds will increase and rain will develop from south to north starting in the mid-to-late afternoon. Highs will be near 60 degrees.

Rain and thunderstorms are likely Thursday, and this will be the desperately needed rain we need, as many of us could exceed one inch of rainfall. Lows will be in the mid 40s.

Rain ends Friday morning, with some sun coming out during the afternoon. However, it will become windy, perhaps even windier than Wednesday afternoon, with gusts up to 40 mph. Highs will only near 50 degrees so, compared to where we’ve been, it’ll actually feel a little brisk out there.

It will be partly cloudy Friday night, with lows in the mid 30s.

Weekend forecast

Saturday will start with at least partial sunshine, then clouds increase and showers are possible by late afternoon. Highs will be in the mid 50s.

Showers are likely Saturday night, with lows in the mid 40s.

Showers end early Sunday, then it becomes partly cloudy and breezy with highs in the low 50s.
