  1. January 15-16 Artic Boundry Event

    Sevier County just closed!
  2. January 15-16 Artic Boundry Event

    18z NAM quite obviously fatter and more juicy than 12z NAM.
  3. January 15-16 Artic Boundry Event

    Yeah I'm hoping we can get a flow off the mountains and get us an extra inch or 2 like what happened with a couple of other events in recent years.
  4. January 15-16 Artic Boundry Event

    What do yall think for snow potential for Sevier County? I'm thinking 1-3" but I just wanna know others' opinions.
  5. Winter Speculation 17/18 -December Thread

    18z has an interesting situation setting up aside from the clipper system during the day Friday. This is associated with the coastal runner and presents more snow for NC than the previous 12z run, almost trickling into eastern portions of the TN valley but not quite. 12z Run 18z Run A lot of time left for change, something to watch though. Could get interesting Friday afternoon though.

    My god what a monster.
  7. November 5th, 2017 Severe Weather Event

    Ramping up quick south of Bloomington and a tornado warning is imminent
  8. November 5th, 2017 Severe Weather Event

    * Tornado Warning for... Northeastern Madison County in central Indiana... Northern Delaware County in east central Indiana... * Until 130 PM EST * At 104 PM EST, a severe thunderstorm capable of producing a tornado was located near Fairmount, moving northeast at 35 mph.

    Broad rotation on cell SW of Bloomington, IN. Cell is moving in general direction of Bloomington. Will need to watch.

    What a technical and in deph discussion by SPC. *Sarcasm* ...SUMMARY... Severe thunderstorms capable of large hail, damaging winds, and a few tornadoes will be possible from parts of the mid Mississippi Valley east-northeastward into the lower Great Lakes this afternoon into tonight. ...IN/OH/PA... Have expanded the EHH risk area eastward to include more of central and eastern OH. Trends in surface observations and satellite imagery suggest destabilization will continue over this region, with 12z CAM solutions indicating robust thunderstorm development through the afternoon and evening. Forecast soundings show substantial low level wind speeds and vertical shear, promoting a squall line with embedded bowing/rotating storms capable of damaging winds and isolated tornadoes. Large hail may also occur in any supercells that can become established. The threat should slowly diminish as the storms move into a progressively more stable air mass over western PA. ...IL/IN... Another area of intense thunderstorm development is expected this afternoon along the primary cold front sagging into parts of MO/IL. Most model guidance suggests development will begin near the STL area and spread eastward across parts of southern IL into central and southern IN. Thermodynamic parameters will be stronger in this area compared to farther northeast, promoting a greater risk of large (possibly very large) hail. Model guidance along suggests a slightly higher probability of discrete supercells in this area, with a few tornadoes expected. Eventually, these storms will also congeal into a squall line as they build southeastward toward the OH river.

    Still a few hours room for improvement too. Banding intensity DBZ has also increased.

    NHC also has raised surge estimates a little bit. Mouth of the Mississippi River to the Mississippi/Alabama border...7 to 11 ft Mississippi/Alabama border to the Alabama/Florida border, including Mobile Bay...6 to 9 ft Morgan City, Louisiana to the mouth of the Mississippi River...4 to 6 ft Alabama/Florida border to the Okaloosa/Walton County Line...4 to 6 ft Okaloosa/Walton County Line to Indian Pass, Florida...2 to 4 ft Indian Pass to Crystal River, Florida...1 to 3 ft

    I can see a strong cat 1 or cat 2 at landfall. Thinking an impact maybe similar to Hurricane Erin (1995) on the Gulf Coast. Practically same size and strength at landfall, based off my predictions.
