TN valley heavy rain/flooding week of whenever
John1122 replied to janetjanet998's topic in Tennessee Valley
.55 has fallen here so far. I can't imagine we manage a 3rd straight year of much much AN precip. -
I will end the year with 81.37 inches of rain, breaking the record set last year, with around 90 years of observations within a 4 mile area here.

If the 1954 connection continues into 1955 we may be in luck. January started warm that year. Another 70 in Knoxville in the first week of the month. The second half turned cold and there was a big snow event in the 3rd week of the month. February was up and down with another decent event during the month.

That's impressive. I only made it to 66 today. Which is still extremely warm, but 76 is crazy.

Historic Tennessee Valley Cold, Snow, and Ice Events
John1122 replied to Carvers Gap's topic in Tennessee Valley
Yes, that's what happened here a week later. Power line snapping cement with 2 inch per hour rates for 8+ hours. They literally record 3 to 5 inches for 4 straight days at Tri on the official record. That's a big part of why the extremely low snowfall averages are off in our region. Extremely poor quality control. You can't have a remotely accurate 30 year average when you're missing the biggest events of the timeframe. After looking it adds up to 17.6 falling at Tri airport.- 130 replies

Historic Tennessee Valley Cold, Snow, and Ice Events
John1122 replied to Carvers Gap's topic in Tennessee Valley
It's not right and the maps that accompany them are honestly laughable. As I mentioned, Tri airport goes from 0 snow depth to 13 inches depth on February 2nd-3rd 1996 but has M for snowfall so they don't include it. February 1998, no clue how they missed it. I don't remember it happening how its recorded at Tri, but amounts between 3.4-5.7 inches are recorded over a 4 day span, with something like 18.2 inches falling. But I guess they aren't counting it as one event? No idea honestly. I thought it was a dynamic cooling event that all fell in a shorter time. The Plateau had one a week later with 10-25 inches.- 130 replies

Temperatures are near normal now through 2/3rds of the month, mainly on the strength of two days that were +15-20 in the area. Without those I'm probably -1.5-2.

It's been colder than I expected the last several days, maybe I hadn't been paying attention with all the talk of coming warmth and was expecting it to be warm. Had lows in the upper 10s and highs in the upper 30s to mid 40s several days in a row now.

Not sure about other areas, but we had 4 inches of snow just a couple of days after that severe weather event in late February 1993.

Heavy rain and frequent thunder here. Very windy earlier, but it's died down some in the storm.

Thundering frequently. I expect flakes go fly soon.

The Euro pulled that last year too on the OP. It had me in a 36 inch bullseye days before the storm. I believe I got less than 2 inches.

5 years ago if models were showing what they are now under 100 hours out, I'd be 90 percent sold that we were going to get accumulating snow. These past two years have made me believe its 90/10 in the no snow direction regardless of what models spit out within even 72 hours of an event.

2, 11, 18, 27 and 40 were also pretty healthy for parts of the forum area. 11 dropped 10-13 inches in Memphis/East Arkansas. 28, I admit, would make me pretty happy since it gave me about 2 feet. Fairly encouraging that there are very few blanks in the 50 members. Quite a few show at least an inch for a large amount of the forum area, a good number in the 1-3 inch range as well.

Historic Tennessee Valley Cold, Snow, and Ice Events
John1122 replied to Carvers Gap's topic in Tennessee Valley
After trying to figure how TYS recorded only 8 inches of snow for the February 1st-2nd 1996 event, I went and looked at the hourly data from Feb 1st and 2nd of that year. I recall the snow starting in Knoxville before it did here as it worked it's way South to North, and it had started here by 7-8 pm. Looking back at old news footage at the time, Knox was reporting snow by 8-9 pm as well. This was a cold event with temps in the upper teens to mid 20s in the area. Snow fell in Knox as the temp dropped quickly from 28 at the start to 19. This should have produced higher ratio snows, and that is reflected in observations that are harder to find than the normal big 3 reporting stations you'll find looking at MRX data, which are Tri/Chatt/Tys. On the hourly reports at Knox from Feb 1st freezing precip starts in the form of freezing rain/fog with 10.5 mile vis, and .02 inches of precip fall as freezing rain. The reports then indicated only fog in Knox, but .12 precip falls, then another period with .12 precip falls, this time the temp is in the 20s and the visibility has fallen to 1 mile at observation time. None of this is recorded as snow. Official data says snowfall 0.00, precip .26. I'm 99.9 percent sure that both periods of .12 were in the form of snow. From midnight to 1am on the 2nd, Knoxville records another .12 precip, once again it's labeled as fog. with a visibility of 1 mile. So .36 has fallen at this point, with 0.00 listed as anything but fog. The next observation says snow .13, followed by snow .15. The snow continues with the aforementioned temps falling into the 10s and finally an observed precip amount of .86 falling as snow. The official snowfall is claimed to be 8 inches from that .86, which I think is absolutely wrong based on QPF, temp profiles and observations all around the site. Knoxville had 1.37 fall as frozen but has missing data listed for snowfall and snow depth for the 1st. I figure the .86 with a lot of it falling at temps below 25 would be close to 10 inches on it's own. I'd guess Tys probably actually had 12+ inches of snow like every other station in it's immediate vicinity. But as Carvers mentioned, it's the year of inexplicably missing snowfall data at the big 3 reporting sites from that time frame.- 130 replies

Basically the same story here as Daniel Boone, around an inch on decks and cars, less than half that managed to stay on the ground.

Heavier precip is snow, lighter is drizzle. Down to 38 degrees.

You can tell this is northern stream and not southern stream energy. Winds are N at 12 and another bit of precip just came through as a mix of rain and snow at 40 degrees. Last event it had to get to 34 to change over due to the S flow.

Quite a bit of thunder and just drenching rain today and currently. I am about to cross 75 inches on the year and will soon break the yearly record imby for the last 100 years, though that record was set last year. Amazing that we had one solid month of drought in the middle of it.

Rogersville reported 17 inches from the storm. So the reports you heard were accurate about heavy snow there.- 130 replies

Historic Tennessee Valley Cold, Snow, and Ice Events
John1122 replied to Carvers Gap's topic in Tennessee Valley
The data for February at Tri-Cities is still missing, but I found some other reports in scholarly articles and also I found a mention of snowfall at Tri-Cities and Knoxville on a youtube video of live coverage of the event from a Huntsville tv station. I also noticed that even though official records say M on snowfall and list the entire month of February 1996 with 2.9 inches if snowfall at Tri, the snow depth goes from 0 on 1-31-96 to 13 inches on 2-2-96. Then I looked at nearby sites and found the range of snowfall. So in the Tri/SW Va area the lowest I found was 13 inches. The highest was 16 inches. You could even pick out areas that saw 12+ inches of snow by temperature. It was 6-10 degrees colder in those areas than it was in areas that saw less snow.- 130 replies
