There is very small "brook" which catches the  storm water and flows down the edge of my property down to a creek in the woods

It is flowing

Been a long while..... Grandaughter calls it "Blue Water"

It trickled when our 3 inches of snow melted a while back in Southern Wake

But is really flowing for the first time in I guess many weeks

Lovely sight!

 I got ~0.75” of rainfall from showers mid to late this afternoon with some heavy for a short period. This is the most I’ve gotten in a day since at the very least Jan 18th.

 The new mini-drainage system that was set up in the back portion of MBY seemed to do pretty well although the real tests will probably not come til spring and especially summer.

OK, honest thermodynamics/atmospheric physics questions that has puzzled me for a long time.  Right now my temp is 60.3 °.  Temps are dropping very slowly.  Sometimes on nights like tonight's the temps completely steady out.  The ground is warm so it radiates energy at a high rate.  To slow (or even stop) the temperature decrease, something must be adding energy, but what is it?  The sky is clear so there is no downwelling radiation from clouds.  There is no wind so there is no warm-air advection or turbulent mixing.  Where is the energy coming from?  Is it radiating from the water vapor in the air?

It’s overcast here and you can feel a south breeze. You must be in an isolated hole

What NorthHills said. In addition, dewpoints are relatively high (mid 50s). So, even with clear skies, the high RH (70%+) isn’t conducive for strong radiational cooling as the water vapor acts as a blanket (kind of what you were speculating).
