It was a dark and stormy night

Whew! We definitely got some rain last night! Doppler radar and ground reports indicate that anywhere from 2-6 inches of rain fell across the plateau last night. The highest totals are in the southern half of Cumberland County. I outlined Cumberland County in the image below and circled Crossville. These are radar estimated rainfall totals from last night. The yellows are 2-2.5″, the oranges are 3-4″ and the reds are 5-6″.  Here at TAP our rain gauge picked up 2.49″ since midnight.


That band of heavy rainfall is the result of the disturbance I mentioned yesterday that was going to move through overnight. It was expected to strengthen and it sure did that! It rode right along a stationary boundary that had draped itself across the state.

We’ll see more rain showers today as the cold front slowly moves on through and to our south. We’ll maybe pick up another tenth of an inch or so of rain. Temps will start to fall, as well. You should notice a drop in temps around lunch time and through the afternoon. Tonight, showers may linger as temps fall to around 40 degrees. Those clouds will hang around through Wednesday, with highs near 50. Looking at satellite, there are clouds ALL over the country. Hopefully, some drier air will work in here for Thursday and clear our skies out. Those clear skies will allows us to frost and freeze both Thursday and Friday nights, with lows around 32. Afternoon highs each day will be in the low 50s.

So, for those of us who are snowbirds we have to ask…..what if all this rain had been snow?  The basic rule of thumb is that one inch of rain equals ten inches of snow. That’s the basic rule of thumb. However, that’s not the whole story. If you’re snow is dry and powdery, one inch of rain could equal as much as 20 inches of snow. And, of course, if it’s a wet, heavy snow one inch of rain may equal as little as 5 inches of snow. We had a snow event here in Cumberland County back in February of 1998 (I’m almost certain of that year) when we had a very destructive wet snowstorm. In that event, one inch of rain equaled only 3 inches of snow! The trees were dripping water because the snow was so wet. So, if we take the rule of thumb of one inch of rain being 10 inches of snow, we’d have about 30-60 inches of snow right now. Wouldn’t that be wild!? If it were a dry, powdery snow we might have as much as 100 inches!  But, I guess we’ll have to settle for rain for now and just dream about what could have been…..

I just noticed that the dark clouds of the cold front are moving in (9:00 a.m). It won’t be long before our temps start to drop back to normal. You all have a great day and stray warm and dry!
