Metro Detroit weather forecast: Still mild, but colder air on the way

Plus: Did somebody say SNOW?


DETROIT – Mostly cloudy tonight, with lows in the mid to upper 30s (3° Celsius).  East wind at 4 to 8 mph.

Mostly cloudy on Wednesday (meaning there could be some breaks of sun), with highs in the low 50s (11° Celsius). Southeast wind at 10 to 15 mph.  Wednesday’s sunrise is at 7:56 a.m., and Wednesday’s sunset is at 5:02 p.m.

A chance for light rain showers Wednesday night, with lows in the upper 30s (4° Celsius).

Partly cloudy and a little breezy on Thursday, with highs in the low 40s (5° Celsius).

Becoming mostly cloudy Thursday night, with lows in the upper 20s (-2° Celsius).

Mostly cloudy and breezy on Friday, with snow showers possible.  This snow will be the result of breezy west winds bringing cold air across the large southern part of Lake Michigan -- a convergence band normally sets up and brings more snow showers to some areas than others.  Past experience suggests that this would be somewhere between I-96 / I-696 and I-94 -- some of you could see some fairly robust snow showers from time to time, which could coat grassy surfaces. 

But this won’t give us the White Christmas so many of us want, as warmer air and rain returns next week and melts it all away.  Highs in the mid 30s (2° Celsius).

Snow showers diminish Friday night, with lows in the low 20s (-5° Celsius).

Partly cloudy on Saturday, with highs in the mid 30s (1° Celsius).

Partly cloudy Saturday night, with lows in the low to mid 20s (-4° Celsius).

Partly cloudy on Sunday, with highs in the low 40s (5° Celsius).

Warmer with a chance of rain on Monday, with highs in the mid 40s (7° Celsius).

Partly cloudy on Tuesday, with highs in the mid 40s (6° Celsius).

Rain chances return on Wednesday, with highs near 50° (10° Celsius).

So, will we have a White Christmas? The odds are decidedly against us, but we have one possible chance.  The computer models are 180-degrees different on the Christmas Eve Day weather pattern. The ECMWF model is rather progressive with the Wednesday weather system, and dries us out on Thursday. 

However, the GFS model holds off the cold front until Christmas Eve Day (meaning more rain on Thursday), and suggests the potential (nothing guaranteed…just a suggestion) that there could be some lingering moisture behind the front. 

IF temperatures cool off enough before the moisture is stripped out, then it’s not out of the question that we could get some Christmas Eve snow (IF the GFS model verifies).  It’s way too early to say with any confidence if this scenario will play out (or, even if it does, it we’d even get enough snow to coat the ground), but it’s certainly something to keep an eye on and hope for!
