In case you haven’t heard by now, there is a 100 percent chance of snow on Thursday.
That’s 100 percent. For sure. It’s going to snow. Really.
That was the word late Tuesday afternoon from the National Weather Service Office in Old Hickory which is calling for snow to begin falling in the northwest counties of Tennessee likely after midnight tonight and heading our way through the early morning hours and continuing during the day.
“Bundle up, I guess, is the thing to do,” said Bobby Boyd, meteorologist with the NWS, and a resident of West Wilson County.
A winter storm watch was issued yesterday for late Wednesday night through Thursday afternoon. Total accumulation is expected to be between 2-4 inches.
In addition to the expected snow, temperatures are going to continue to drop into the single digits for a low by Friday night with wind chills from zero to about minus 5.
You should take precautions, if you haven’t already, to make sure pipes are protected from freezing and bursting. You also want to make sure the elderly have enough heat, and you also should bring pets indoors or make sure they are at least where they can have enough warmth and water, also.
Dress in layers if you must go out, and be careful if you are on the roadways because the winds are expected to increase potentially causing problems with blowing snow and such.
Above all, pay attention to the latest weather reports on T.V., commercial radio or NOAA Weather Radio.
The high pressure system that will bring the snow this way was over the northern and central Plains on Tuesday and was expected to gain strength today and move into the southern Plains. Boyd said it should be moving toward the Middle Tennessee area by tonight.
“There is a lot of cold air behind it,” he said, noting the pressure yesterday stood at 1051 millibars, which he called “a real high reading. A real strong high pressure system means pretty cold temperatures.”
Snowfall in the Davidson County, Wilson County area will probably begin about daybreak on Thursday and continue through the early afternoon when temperatures will be colder. The snow will taper off for a while, but by Thursday night will pick up again.
“By Thursday night, we’ll still have some around,” Boyd said.
That system will move on, in time for another Artic high to settle in for the next several days.
First things first, however. Today’s high should reach 31 degrees. Skies should begin to cloud up later today, becoming cloudy tonight with a low of 23 and snow moving in after midnight, closer to daybreak here.
Thursday’s high should be about 28 with a 100 percent chance of snow. Look for flurries later, but more snowfall is expected Thursday night, perhaps up to another one-half inch. The low should be 13.
Winds will be increasing Thursday coming from the south at 5-15 mph becoming west northwest. Winds could gust as high as 25 mph.
There is a 30 percent of snow flurries on Friday with a high of 28. The low Friday night should drop to 8 with a 20 percent chance of snow flurries. The high Saturday is expected to be near 20 with a chance of flurries. The low Saturday night should again be about 8.
Sunday will be sunny with a high of 29. The low Sunday night should be 17. The Middle Tennessee area will be on the back side of the high pressure system on Monday and it will be warmer at 38 degrees, if you can call that warmer. The low Monday night should be near 25.
Boyd noted that the Davidson County-Wilson County area could be off to the coldest start of any year on record. “Prior to 2010, the coldest first 10 days of January was in 1942. Other cold starts were in 1879, 1887, 1884, 1988, 1970, 1940, 1968, 1977 and 1979.”
