As a (somewhat) new resident to this area, I am curious to know how well the local electric utilities usually handle storms like these. Are the power lines pretty robust around here? I'm seeing these reports out of Oklahoma, etc. saying that 1/4" of ice on wires can cause problems. Hopefully our precip will not include much freezing rain or ice.

Hi Paul:

To answer your question, I do believe the power lines are robust in this area. Additionally, the men and women who work for the Electric Department at the City of Cookeville and for Upper Cumberland & Volunteer Electric are excellent and will work all night to restore any damage we may see during this winter storm!

Hey, report back to me with, etc!! :)

Hello Michael,

Thanks for all the up to date info about the storm. I am curious how the installation of your new Davis Vantage Vue weather station is going. Is the installation a challenge?

Stay warm,

tncorgi said...

Thanks for answering my question, Michael. Also I forgot to mention that I'd like to revise my vote in the poll, I indicated 3-8 inches but should have said FEET! haha

The NWS is encouraging spotter reports, as long as I don't lose Internet (which even on a sunny day can be iffy with Charter) I plan to send some in. Should be an interesting 24-48 hours...

Michael Detwiler said...

Bill...the installation was a BREEZE!! (pun intended) You are welcome to swing by sometime and see the whole setup. I'm sure there has to be some $$$ in the budget for the school to install one! ;-)

Michael, do you have a website where we could view reports of snow totals around the mid-state?
Thanks for all of the great work!

As of 10pm we have sleet and 32 degrees in NW Cookeville, 3 inches of snow on the deck. Not a nice combination. Had to drive my wife to work in Algood, the worst roads were 12th Street by Tech and on Washington Avenue. Downtown Cookeville intersections also very slippery due to accumulated slush from all the traffic. NO sign of any salt, spray trucks or plows this evening. Guess they'll be back at it in the AM.

Michael Detwiler said...

I've been listening to the scanner Paul and slick roads all over the city! Crazy times, welcome to Florida folks love this snow, don't you? :)

As you know, precip. has been mainly sleet/feezing rain over the last hour or so. As you posted, temps are falling and we expect a change-over to all snow soon.
Was that temporary change-over expected? Or will that affect our overall accumulation and we won't quite hit the 7-9 or 9-11 mark anymore? This change over has gotten me a little worried...haha

Michael Detwiler said...


True, it has been a mixture. Expecting temps to trend downward over the next several hours and an upper level low will develop and reinforce the precip. If we go back to all snow, we could see some impressive accumulations by morning. Currently at 3" in my yard.
