  1. Mesoscale Discussion 0257 NWS Storm Prediction Center Norman OK 0229 PM CDT Thu Mar 25 2021 Areas affected...far northern Mississippi into Middle Tennessee Concerning...Severe potential...Tornado Watch likely Valid 251929Z - 252130Z Probability of Watch Issuance...80 percent SUMMARY...The threat of severe storms including tornadoes will increase by late afternoon into Middle Tennessee and persist through the evening. A watch may be issued by 21Z. DISCUSSION...Surface analysis currently shows a warm front into far southwestern TN extending east/southeast into northern AL. Meanwhile, another warm front extended from the developing surface low from southern IL into central KY. In between these two fronts, gradual warming is taking place, with temperatures now into the low 70s F. MUCAPE currently remains below 1000 J/kg as a result of dewpoints near 60 F. Strengthening 850 mb winds out of the southwest later today should aid moisture advection out of MS into Middle TN, with areas of heating helping to destabilize as well. Shear will become increasingly favorable for tornadic supercells in the 21-03Z time frame, and a few tornadoes are anticipated as the mid 60s F dewpoints arrive later today. With the more unstable air in place, effective SRH may reach 400-500 m2/s2. ..Jewell/Hart.. 03/25/2021

  5. Couple days ago there was hardly any low level shear ay 3 Convective Outlook NWS Storm Prediction Center Norman OK 0235 AM CDT Thu Mar 25 2021 Valid 271200Z - 281200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE LOWER MISSISSIPPI AND TENNESSEE VALLEYS AS WELL AS THE MIDWEST... ...SUMMARY... Isolated strong to severe storms are possible Saturday across the lower Mississippi through Tennessee Valley regions. Other strong to severe storms are possible across a portion of the Midwest. Isolated damaging wind and large hail are the main threats. ...Lower Mississippi through Tennessee Valley region... Some thunderstorms will probably be ongoing early Saturday, mainly across a portion of the TN Valley. There is some uncertainty regarding how these early storms evolve, but this activity will probably shift northeast and weaken with time. Under the influence of a broad fetch of southwesterly low-level winds, richer moisture with surface dewpoints in the low to mid 60s F will advect northward into this region contributing to moderate instability with up to 1500 J/kg MLCAPE. Other storms might develop during the evening or overnight within the warm advection regime as the low-level jet strengthens. A cold front associated with a northern stream shortwave trough will approach this region from the northwest and likely contribute to the development of additional storms overnight, likely consolidating into lines and clusters. This activity will be embedded within strong vertical wind profiles supporting the potential for a few organized structures capable of mainly isolated strong to damaging wind gusts and hail. ...Midwest region... Low-level moisture will be more limited in this region. However, cold air aloft will compensate and the atmosphere could become at least marginally unstable as the boundary layer warms during the afternoon. Storms may initiate along frontal zone within a strongly sheared environment supportive of a few organized storms capable of isolated large hail and damaging wind. ..Dial.. 03/25/2021
  6. 3kNAM is showing what Jeff said up above.The OFB starts to work its way up from MS/AL.In the mean time a inverersion will be into place late morning into early afternoon,this inversion will break early afternoon and the storms should start to explode mid afternoon

  8. Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1228 PM CDT Wed Mar 24 2021 Valid 251200Z - 261200Z ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE LOWER MISSISSIPPI VALLEY/MID-SOUTH INTO THE TENNESSEE VALLEY AND SOUTHEAST... ...SUMMARY... The potential for an outbreak of severe storms including several long-track strong tornadoes, scattered large to very large hail, and severe/destructive winds, will exist Thursday into Thursday evening across a portion of the lower Mississippi Valley, Tennessee Valley, and Southeast. ...Synopsis... A shortwave trough with attendant 70-100 kt+ mid-level jet will eject northeastward from the southern Plains across the lower/mid MS Valley on Thursday, and continue over the OH Valley and lower Great Lakes region Thursday night. At the surface, a weak low over northeast TX at the beginning of the period Thursday morning is expected to likewise develop northeastward to the mid MS Valley through the day while deepening. A warm front attendant to this cyclone will likely lift northward across the lower MS Valley/Mid-South and TN Valley towards the lower OH Valley by Thursday evening. ...Lower Mississippi Valley and Southeast... Storms will likely be ongoing at the start of the period from northeast TX into southern AR and northern MS/AL and TN. This activity will likely be supported by a southerly low-level jet and related warm advection. These storms should shift northward through the morning, allowing for destabilization via diurnal heating to occur across the lower MS Valley. Rich low-level moisture with at least mid to upper 60s surface dewpoints (perhaps lower 70s), should advect northward across parts of the lower/mid MS Valley, TN Valley, and Southeast by Thursday afternoon. This increasing moisture, coupled with diurnal heating, will likely support MLCAPE of 1500-2000 J/kg developing over a fairly broad portion of these regions. A pronounced low-level jet (50-60+ kt) will overlie much of this region as well, as large-scale ascent from the ejecting shortwave trough overspreads the lower/mid MS Valley vicinity. Strongly veering and strengthening wind profiles from the surface through mid levels will support supercells. 0-1 km SRH along/south of the surface warm front will likely reach 300-500 m2/s2, and low-level mesocyclones capable of producing strong, long-track tornadoes appear likely with any supercells that can form. Scattered large hail, some of which may be 2+ inches in diameter, and severe/destructive winds also appear probable, both with supercells and any bowing line segments that can develop. At this time, the best potential for strong tornadoes appears to extend from parts of central/northern MS into western/middle TN and central/northern AL, mainly Thursday afternoon and evening as storms move generally northeastward. Concern does exist regarding the effect of storms forming during the morning on the development of instability, and potential for destructive interference from too many storms developing across the warm sector at the same time. Still, given the very favorable environment forecast across this region and the potential for numerous supercells, an upgrade to High Risk for multiple strong to potentially violent, long-track tornadoes may be needed in a later outlook update. ...Ohio Valley... Fairly widespread precipitation should occur over a majority of the lower OH Valley through the day. This should temper diurnal destabilization to some degree, but weak instability will probably still develop along/east of the surface low and northward-moving warm front. At least an isolated severe threat may develop late Thursday afternoon into the evening as the southerly low-level jet strengthens over this region and low-level moisture increases. The potential for a low-topped line of storms capable of producing damaging wind gusts and tornadoes will exist given the strength of the low-level flow and related shear. These storms will likely be tied to a cold front as it tracks northeastward through the evening and overnight hours. ..Gleason.. 03/24/2021

  10. See what the models show today.Euro6z went back to the west,probably just slower but the west shift shows a better LLJ
  11. Looks like they are updating the maps daily now,time stamp says the 19th but it's been updating everyday
  12. 18z Euro is further east and weaker ,about where the GFS shows it at 0z Friday but the GFS 18z is now stronger
