Well hang on because those cold reinforcements are yet to come for Southeast Lower Michigan. They, basically will come down in two cold waves; the first (and the worst) will arrive during Monday, while the second comes down later Wednesday, just to "seal the deal". Gusty winds with bone chilling wind chills down as low as zero or below will accompany snow showers and squalls to complete the 5 week before winter scenario. Looks for temperatures to range from mainly the 20s for highs and teens and even some single figures for lows, during the coldest time in the up coming week. Normals this week; mid to upper 40s for highs and lower 30s for lows. So several days we won't crack the normal lows! In fact, some days this week won't match the normals for the coldest winter days in later January!
Ironically (as mentioned in my last blog, below), we should be engulfed in the throws of the Arctic regime around the same time as the incredible cold wave of 1880! A welcome moderation, finally should commence this next weekend /22nd-23rd/ and beyond (at least for awhile) so those records for next weekend /22, 23/ look more than safe.
"It will be interesting to see if we can challenge the resilient stretch of record low temperatures for mid November that I wrote about here, previously as SE_Mich Weather Historian (and earlier with the NWS). This record cold stretch occurred /1880/ way back near the dawn /1874/ of official records at Detroit and still hold up till this day! Both the intensity of the cold that we experience and timing may be an issue, we'll see. Something to keep in mind, especially if we have snow on the ground at the time".
DETROIT - NOVEMBER RECORD LOW MAXS AND LOWS IN BLUE
Now while it remains to be seen if we can break any of those archaic records at Detroit from 1880. Flint and Saginaw may be another story, as their records don't include the brutal cold of 1880 for November and little, if any heat island affects those sites. Still, they both have some decent standings in the cold record department this week and several may be a tough "ice-cube" to crack....
FLINT - NOVEMBER RECORD LOW MAXS AND LOWS IN BLUE
SAGINAW - NOVEMBER RECORD LOW MAXS AND LOWS IN BLUE
It will largely depend on the cloud cover and snow cover. While this air certainly has the potential for record cold, I would be remiss if I didn't mention the importance of cloud cover, snow cover AND perhaps the most important; the overall moderating affects on the Arctic air mass - the Great Lakes. Still with the right conditions...
Here are the villains in the piece this week....

That's incredible to have such a low height/cold Polar Vortex over the northern Lakes in MID NOVEMBER! Got to be a record in upper air data if she verifies...
Keep you and the pets warm.
Next Up - What's the big travel day Wednesday along with Thanksgiving/Thanksgiving weekend look like?
