Upside down weather
I love it when the weather does things it's not supposed to.
Overnight temperatures usually fall to the daily minimum just after sunrise. But sometimes at night advection, or the horizontal transport of air thought the atmosphere, overcomes the normal diurnal variations in temperature. When that happens, temperatures can rise at night, or fall during the day after a strong cold frontal passage.
Overnight temps at Twin Cities airport rose 9 degrees in just 3 hours as a warm front pushed through between 3am and 6am this morning!

The warmest air will pass overhead during the morning and midday today. We should see many reading in the lower 40's. Canby hit 48 Sunday with little or no snow cover, but with 4 to 5 inches still on the ground in the metro, our temps should stop shy of today's record of 47 degrees.
We'll get the falling daytime temperature part of the equation Tuesday after the next in our series of arctic fronts this winter barrels through early Tuesday morning.
Enjoy the warmth today; winter comes back in a big way in the next 24 hours with 1" to 2" of snow and a return to wind chill babble. We will bottom out around -10 Wednesday morning in the metro, and -30 up north before temps will moderate again late in the week.
It's a real winter this year!
