  1. Pretty nasty line that moved through West TN about 4 am. Over 8 thousand without power in my area. I'd estimate 60-70 mph gusts
  2. Picked up over 3 and a half inches of rain this morning in Obion County. Several reports of culverts and bridges washed out as well. Snapped these around 9 am.
  3. Same here in Union City, picked up an inch so far...coming down at a pretty good rate too. If we avoid any dry slot/dry air, we could pick up a few more inches
  4. Official totals have been bumped down here in far NW TN with the SE trend. An impressive string of advisories/warnings with this one too. Hopefully some of you guys will cash in
  5. Clouds cleared out overnight here allowing the temps to really bottom out. Minus 1 this morning, -9 wind chill
  6. Snow starting to wind down here. Kind of hard to tell here but this photo was taken in the road in front my house. Going to be a fun commute in the morning!
  7. About half an hour ago In Union City
  8. Hoping to get under a good band before this is over, it has been only light to moderate snowfall so far. Still managed to rack up about 3 and a half inches this morning.
  9. I'm thinking maybe 5-6 here, on the low end for sure. Not complaining tho!
  10. Starting to see some of the heavier returns settle in my way, starting to see some nice accumulations in a few areas
  11. Both PAH and MEM morning discos mention up to 20:1 snow ratios for this afternoon....unreal for this area 8 degrees this morning with a wind chill of -11. Gusts to 24. Brutal! From PAH: Additionally, with very cold tropospheric temperatures, snow-to-liquid ratios of 10-15:1 this morning are forecast to increase to 15-20:1 by this afternoon. So the combination of the strong forcing, high QPF, and high SLRs will contribute to very efficient snow accumulation. Overall, storm total snow accumulation of 6 to 10 inches is expected, with some localized totals up to a foot. Add in the north winds of 10 to 15 mph with gusts up to 20 to 25 mph, and blowing and drifting snow will be a problem. All this adds up to a serious situation that will cripple the flow of traffic and commerce in the region. And dangerously cold sub zero wind chills in many locations heightens the threat to life. As a result, the Winter Storm Warning will continue through tonight. MEM: Short term...(Today through Tuesday)...An 850 mb low will move from Central Arkansas today northeast into the Ohio Valley tonight. Ample moisture and strong large scale forcing combined with a very cold arctic airmass will continue to produce wintry precipitation across the Mid-South throughout the day and heavy at times this morning and into this afternoon. Analysis of short term model soundings indicates precipitation will remain snow over Northeast Arkansas, the Missouri Bootheel, and Northwest Tennessee, initially a mix of sleet and snow along and south of I-40 and gradually transitioning to all snow this morning near the Mississippi River and gradually across the remainder of West Tennessee into this afternoon. Snow ratios will average from 20:1 near the MO/KY border to 15:1 towards North Mississippi. Meanwhile, precipitation across most of North Central and Northeast Mississippi will be a mixture of sleet and freezing rain then gradually transitioning to snow towards the end of the event towards this evening. Areas to the southeast of Tupelo are most likely to experience freezing rain for much of the event and the Winter Storm Warning was transitioned over to an ice storm warning where one quarter to one half inch of ice accumulation may occur.
  12. Slept in a little later than I wanted to this morning..haha Most of what is covering the ground we picked up with the last wave that came through sometime between 3 and 6, I'd say an an inch and a half to two inches
  13. I was wondering how close some of the p-type algorithms are to actual conditions on the ground. The progression of this Arctic air has been a gem to watch unfold.
  14. Radar starting to fill in. It will be interesting to see how some of the short term models handled this first wave
  15. PAH Disco hinting at an excess of a foot where banding sets up- National Weather Service Paducah KY 238 PM CST Sun Feb 14 2021 .SHORT TERM...(Tonight through Monday night) Issued at 238 PM CST Sun Feb 14 2021 A major winter storm is taking aim on the area. The first round of snow will be tonight in a zone of increasing low/mid trop frontogenetical forcing positioned out ahead of the main upper trof, that by 12z Monday should be over the central and southern Plains. We may see an initial 1-3" of snow tonight (give or take). We have incorporated the HREF closely with a consensus of deterministic guidance for tonight and Monday (see below). We will be close to Wind Chill Advisory conditions again tonight across portions of southeast MO and southwest IL. We have addressed the bitter cold in our current Winter Storm Warning that remains as is from 6 PM Tonight through 6 AM Tuesday. Monday, the main energy within the mid level trof comes up over top of the region in the afternoon and evening. This will be the round of greatest significance (snow rates, accumulations, impacts). The overall trend seems a bit faster, so the lull is not expected to last real long. WPC banding probabilities increase notably with the main wave, with some inference of instability and prominent snowfall rates. The HRRR depicts this possibility as well. So for now we have storm total accumulations 6 to 12". Given above average snow to liquid ratios and this added concern, 12" may not be high enough should some of these indicators pan out. But for now, we have headed the right direction in our opinion. The snow will taper off Monday evening and should be all but completely over across southwest IN and the KY Pennyrile region after midnight. In terms of messaging, the bitter cold remains a real concern with this system, as does the potential for blowing snow with NNE winds 10 to 15 mph gusts to 20 mph or even slightly higher. Stay tuned for updates and adjustments to snow amounts (if needed). .LONG TERM...(Tuesday through Sunday) Issued at 238 PM CST Sun Feb 14 2021 The main focus later this week continues to be another potential winter storm Wednesday into Thursday. This system is still four days away, so many details remain to be ironed out. The 500 mb pattern actually appears more complex than it did yesterday, mainly because a northern stream 500 mb shortwave has entered the picture. This northern stream shortwave will move down into the northern Plains mid-week. There is some potential for this shortwave to shunt our moist southern stream shortwave further south. This is reflected in a majority of the model qpf fields, which show the heavy qpf suppressed more to the south of the Ohio Valley than they did yesterday. There is also less of a warm air intrusion, which results in less mixing of wintry precip. In a nutshell, the 12z models are still split into two camps. The European solutions have trended even farther to the southeast, taking the surface low northeast from the central Gulf Coast to Georgia. The gfs ensemble mean is also further southeast, taking the surface low across Alabama Thursday. The gfs consensus basically places our region in the sweet spot for heavy snow, with heavy qpf shown by the gfs ensemble mean over the Ohio Valley and se Missouri. An elevated warm nose in the gfs guidance would result in mixing with sleet or freezing rain se of the Ohio River. Until the models resolve the influence of the northern stream shortwave, the forecast will remain in flux. A forecast trend toward drier and colder conditions is possible if the northern stream becomes more dominant. The models at face value today do continue to suggest the likelihood of a winter storm Wednesday into Thursday. Otherwise, the main story on Tuesday into Wednesday will be the continued bitterly cold wind chills. Following the late week winter storm system, high pressure will pass overhead on Friday. In the wake of the high, southwest winds are expected to bring above freezing temps this weekend following the extended winter blast. The ecmwf and gfs mos highs in the 50s at pah Sunday look a little unrealistic given the snowcover, so the forecast will be for highs in the 40s. Model ensemble means have been in good agreement on a nearly zonal flow aloft this weekend. &&
  16. I would assume they mean when all is said and done, the consecutive days below freezing will be the longest. Saturday is currently forecast to be 38, gotta wonder if we will make that with inches of snowpack likely still on the ground.
  17. Interesting stat out of Memphis concerning temps, the extent and duration of this Arctic mass is impressive to say the least
  18. NWS Paducah is starting to get on board w/some of the higher totals, they just posted this graphic...was 6-8 this morn
  19. Looks like Memphis pushed up the start of the WSW due to impacts from the snow currently falling. Picked up a half inch or so here in the past few hrs. Winter precipitation is already beginning to spread into the Mid-South this morning. The precipitation is associated with a weak shortwave that is moving through the area. Most of the precipitation reports have been in the form of snow, but have gotten a few sleet reports as well. Went ahead and pushed up the start time to the Winter Storm Warning as whatever is falling is sticking to the ground causing impacts. Will update to make some minor temperature adjustments as well as don`t expect temperatures to budge much similar to yesterday. Will also let Wind Chill Advisory expire at 18Z, but will be addressing wind chill concerns within the Winter Storm Warning as below zero wind chill values will continue through the storm possibly even longer. Update will be out shortly.
  20. It will be interesting to see how these ratios come into play. It is so freaking cold (8 degrees with a -6 wind chill this morning) that any bit of moisture is squeezed out as snow. Steady flurries/light snow overnight has already covered the roads here in Obion County.
  21. The last major one for me (Nw TN) was March 5th of 2015, we got slammed with around 12-15 inches. There were a couple of back to back systems that week as well if I remember it correctly. Measured this off my sidewalk this next morning.....maybe a repeat coming??
  22. I went ahead and edited the existing thread, if someone wants to make a new one I'm totally fine with that. Looking forward to the discussion either way.
  23. I would say so. Perhaps some of the more knowledgeable guys can chime in on this one, but the ice didn't seem to accreate on the trees and power lines much, thankfully. We had several bursts of heavy freezing rain overnight, maybe runoff was an issue. Either way, I'm thankful. I'm as big of a winter weather fan as the next guy, but these ice storms aren't much fun. Hope we all score on some snow this coming week though.
