Arctic blast No. 1 is on the way to Michigan

Arctic blast No. 2 will be even worse


DETROIT – Scattered snow showers are likely tonight, but that's not the main story: Arctic air plunging southward behind a strong cold front will drop our temperatures quickly -- we should easily be in the low teens by daybreak.

Northwest wind increasing to 15-20 mph, creating wind chills between -10° and -15°.

Mostly cloudy, windy and bitterly cold on Thursday. Temperatures may actually slowly fall during the day into the single numbers by dinner time, with wind chills between -10° and -20°.

One note for you folks near Lake Huron: wind trajectory will be critical. If the wind blows from the north-northwest, then lake effect snow bands will primarily affect Ontario. However, just a slight backing of the wind to more of a due northerly direction would bring a few bands to the Michigan side of the lake.

Becoming mostly clear Thursday night, with lows between 0° and -10°, and wind chills probably around -15° -- very close to the school closing criteria. Remember that ClickOnDetroit.com has Detroit's best school closing information network -- we'll keep you apprised.

Becoming cloudy on Friday, with highs in the mid to upper teens.

Snow develops Friday night, with lows in the low to mid teens.

Snow continues on Saturday. This doesn't look like a massive snow-maker…perhaps 1" to 2"…but the weather headline once again is the next batch of bitter cold air headed our way. Wind will pick up Saturday afternoon, and temperatures will plummet as Arctic Blast #2 moves in. Highs in the low to mid teens should be set early in the day, with temperatures back into the single numbers by late afternoon.

Valentine's Day night is going to be very windy and brutally cold, with wind chills in the evening around -15° to -25°, and possibly dropping as low as -30° by Sunday morning. Actual low temperatures without the wind chill will average around -8°, and possibly even colder in our typically colder suburban areas.

Mostly sunny with diminishing wind on Sunday, and highs only around 4°. Of course, any wind at all will create sub-zero wind chills, although the sun will certainly help.

Mostly clear and continued bitterly cold Sunday night, with lows once again averaging around -8°, with wind chills between -10° and -15°.

Partly cloudy on Monday, with highs in the mid teens.

There's a chance for some snow Monday night and Tuesday. The long range computer models are spinning up a pretty significant winter storm, but right now keep it barely to our east. Any westward jog (and it's obviously still many days out), could bring significant snow to us.

I'll keep you posted on this. Regardless of how much snow we get, more Arctic air is headed this way behind this storm.
