Weather roller coaster to continue in metro Detroit

Plus, a nice honor in Paris to tell you about


DETROIT – Any lingering early evening snow showers should end quickly, with skies becoming mostly clear overnight.

It's going to be a cold one, though, with lows in the low to mid teens (and only a little warmer in the Detroit Heat Island). North wind at 10 to 15 mph.

Saturday should feature bright, sunny skies, with highs in the low to mid 30s. Wind will be light, so this should be a spectacular day -- albeit much chillier than we'd all like.

Saturday's sunrise is at 7:23 AM, and Saturday's sunset is at 7:54 PM.

Mostly clear Saturday night, with lows near 20°.

We'll start the day on Sunday with sunshine through high, thin cirrus clouds. However, those clouds will tend to thicken and lower through the day, and we'll see some rain showers develop by late afternoon. It's going to become windy, too, with a south wind at 15 to 25 mph by afternoon. Highs in the mid 40s.

Rain showers mix with wet snowflakes Sunday night. Lows in the low 30s.

Becoming mostly sunny on Monday, with highs in the mid 40s.

Increasing clouds Monday night, with a possible rain or snow shower. Lows near 30°.

The computer models differ on the timing and placement of the storm system crossing the state Monday night into Tuesday. For example, the GFS model tracks the storm across Mt. Pleasant, the ECMWF model tracks it across the Michigan/Indiana/Ohio state line, and the CMC takes it across the Ohio Valley! If we take the GFS and CMC at their word, we get no precipitation on Tuesday. If we go with the ECMWF, then we have a shot at some measurable snow.

Since the upper level disturbance that will generate this system is still over the Gulf of Alaska, the models won't start developing any kind of consensus until it crosses over the continent and can be studied by our upper air weather balloon network. High temps are also highly dependent upon the storm's track: if it takes the northern track, then we hit the low 50s. If it takes the southern track, then we're stuck in the 40s. Stay tuned.

Partly cloudy Tuesday night, with lows in the low 30s.

Mostly sunny on Wednesday, and there's going to be a difference in temperature across the area. Highs in the mid to upper 50s…possibly even near 60°! One thing to monitor is the wind direction -- the GFS model suggests a southeast wind on Wednesday that would keep you folks on the eastside noticeably cooler due to the cold Great Lakes.

Increasing clouds with a chance of showers Wednesday night. Lows in the low 40s.

Partly cloudy and Breezy on Thursday with a shower possible. Highs in the upper 50s.

There's still a chance of showers Thursday night, with lows in the low to mid 40s.

Rain chances continue on Friday, with highs in the low to mid 50s.

Alright, before closing this article, just a quick note that I'll be away for a few days representing the United States at a special conference in Paris for TV meteorologists from around the world. Each year since the late 1990s, I have been invited to this special gathering with two or three other U.S. colleagues. The Forum International de la Météo et du Climat was started in the early 1990s by a great Frenchman, Francois Fandeaux, whose dream was to bring the world's broadcast meteorologists together to learn with each other, and from each other.

Following Francois' untimely death, Christian Vannier and Morgane Daudier have kept the dream alive, and work hard to get sponsorships to fund the entire trip for TV meteorologists from 40 to 50 countries. Having had the privilege to attend for so many years, I have developed very close friendships with some of my international colleagues, and we all stay in touch updating each other on significant weather events around the world -- and that helps me provide you with more pertinent information about these events.

For example, when recent significant typhoons threatened the Philippines, my friend Lia Cruz in Manilla kept me updated. When a total solar eclipse moved across northern Europe, my friend Helga van Leur from The Netherlands told me about her escapades trying to find a clear sky area to see it -- I passed along her funny story in newscast that day. When three inches of snow fell in Jerusalem, my friend Danny Roup did a quick telephone interview with me, and you heard him talk about how the people there in Israel were reacting to the white stuff. The Forum has made me a better meteorologist, and it's a great feeling knowing that I am representing my country.

That's why I get so excited when I watch the Olympics -- I know personally how they feel.

Until next week, au revoir! And by the way, those of you who follow me on Twitter (@PGLocal4) will see some photos from Paris over the next few days!
