Metro Detroit weather: Spring has sprung
Warm weather doesn't last long
DETROIT – What a day. Temperatures soared above 70 degrees (21 degrees Celsius for our Canadian neighbors) areawide, which, combined with the sunshine that developed, made for a gorgeous day.
Let’s pause for a moment and put this into perspective: Tuesday's long-term average high temperature -- computed by averaging high temps for the period 1980-2010 -- is only 56 degrees, or 13.5 degrees Celsius. Not bad for Nov. 1.
While we’re at it, Tuesday is a very important weather anniversary in Detroit. On this date in 1950, the temperature reached a record high of 81 degrees (27 degrees Celsius). This is the latest date that it has ever reached 80 degrees in recorded Detroit weather history. We didn’t break the record Tuesday, but we sure were a lot closer to that than we were to our average high for this date.
Clouds will increase later Tuesday, and it’ll be a mild night, with lows in the mid- to upper 50s (14 degrees Celsius). Southwest winds will be very light.
Believe it or not, a cold front will be dropping through the area later Tuesday, but it initially won’t have much moisture to work with, so I don’t think we’ll see any rain from it. The moisture will increase Wednesday afternoon, however, as the front stalls and then retreats back to the north as a warm front, and that will allow rain to develop and move in.
It will be mostly cloudy to start Wednesday, with some showers developing, particularly north of 8 Mile Road, during the afternoon. Highs will be quite variable, depending on the exact location of the front I discussed above.
Parts of Lenawee and Monroe counties could conceivably get back into the low to mid-70s (22-23 degrees Celsius), with mid- to upper 60s (18-20 degrees Celsius) across the heart of the area and only near 60 degrees (16 degrees Celsius) by the time you get north of I-69. Naturally, the geographic placement of these temps will be dictated by the front’s exact location. Wind will be variable due to the front bisecting our area, but light.
Wednesday’s sunrise is at 8:08 a.m., and Wednesday’s sunset is at 6:25 p.m.
Showers and even some scattered thunderstorms are likely Wednesday night, with lows in the low 50s (11 degrees Celsius). I do not expect any severe weather.
Rain may still be around first thing Thursday morning, with better chances the farther you move to the east, but should end during the morning, with skies becoming partly cloudy behind the cold front crossing the area.
Remember that the cold front is the front edge of a sharply colder but average November air mass, so this cold air advection will severely curtail any temperature rise during the afternoon. I expect mid-50s (13 degrees Celsius) at best for highs. It’ll also be a little breezy (10-15 mph) behind the front, which will add a bit more chill to the air.
It will become mostly clear Thursday night, with lows in the mid- to upper 30s (3-4 degrees Celsius).
If you're a big fan of crisp, sunny fall weather, then get ready for a remainder of my forecast that’ll knock your socks off.
Look for a ton of sun from Friday through next Tuesday, with highs generally between 54 degrees and 60 degrees (13 degrees and 16 degrees Celsius). Overnight lows should average in the upper 30s to low 40s (4 degrees to 5 degrees Celsius). The upcoming weekend looks great for attacking those leaves, hitting the cider mill, watching college football or doing any outdoor activities. Make some plans and take advantage of the great fall weather.
