Metro Detroit weather forecast: Rainy Saturday with thunder and lightning

Temperatures rise to the low 50s by late afternoon

DETROITThe National Weather Service issued a wind advisory for Genesee, Lapeer, Lenawee, Livingston, Macomb, Monroe, Oakland, St. Clair, Washtenaw and Wayne counties until 8 P.M. Sunday.

If there was ever a weekend to have the Local4Casters weather app, this is the weekend as there will be numerous significant weather changes over the next 36 hours.

Why is our app the best in the nation? Because we designed it in-house right here at Local 4. Just go to the app store and search, WDIV. You’ll see it right there and best of all, it’s free! Read on and see why you’ll need the app…

We’ll have a rainy Saturday morning, with some thunder and lightning thrown in for special effect. However, there is no severe storm risk this morning, so don’t worry about that. It appears that we may get a break from the rain for part of the afternoon. Check the radar on our app if you’re trying to figure out a time to get out for a walk or run around the neighborhood. Temperatures will be in the 40s (6 to 9 degrees Celsius) most of the day, but perhaps rise into the low 50s (11 degrees Celsius) by late afternoon south of M-59. Wind will blow generally from the east at 5 to 10 mph.

Rain and thunderstorms develop this evening ahead of a warm front moving northward out of Ohio. While I do not expect a widespread severe weather outbreak, any robust storm that develops north of that warm front could produce one-inch hail. The greater concern (and lower probability) is that a storm near that warm front could develop some rotation, which brings the small chance for a brief, weak tornado. Keep a close eye on our app’s radar this evening.

Temperatures behind the warm front rocket into the upper 50s (14 to 15 degrees Celsius) overnight…watch the warmer temps coming our way on the app this evening, too.

Shower and thunderstorm chances end as a strong cold front crosses the area late Saturday night. Most of us will wake up Sunday morning to those mild overnight temperatures, and perhaps to some sunshine, too.

First thing in the morning is your best opportunity for a walk or jog around the neighborhood. But don’t be fooled: clouds will return, scattered showers will develop by afternoon, temperatures will start falling (into the upper 40s…9 degrees Celsius) by late afternoon, and the wind will increase.

In fact, we could see gusts to 40 mph, and possibly even a little higher. It’ll be interesting to watch the falling temperatures and increasing wind on our app.

Again, it’s going to be a wild weekend of weather. I have you covered on all of our newscasts this weekend on Local 4, on ClickOnDetroit.com, on our app, and on Twitter (follow me at @PGLocal4 for personalized updates). Be safe.
