Hoosier Posted April 10, 2017 Share Posted April 10, 2017 Mesoscale Discussion 0477 NWS Storm Prediction Center Norman OK 0325 PM CDT Mon Apr 10 2017 Areas affected...Portions of IL...extreme east-central MO...IN...southern WI...southwest Lower MI...southern Lake MI...far western OH Concerning...Severe Thunderstorm Watch 138... Valid 102025Z - 102230Z The severe weather threat for Severe Thunderstorm Watch 138 continues. SUMMARY...The risk for severe thunderstorms continues across Watch 138. An isolated severe risk may extend farther south, though additional watch issuance is unlikely. DISCUSSION...Isolated to scattered thunderstorms continue to develop near a front from far south-central WI southward to west-central IL and into east-central MO. The greatest coverage of this activity lies within western portions of Watch 138, in proximity to the strongest deep ascent, and will continue tracking east-northeastward. Surface-based convection encountering the strongest buoyancy will extend across northern parts of central IL east-northeastward into northwest Indiana -- characterized by 1000-2000 J/kg of MLCAPE aided by a narrow corridor of dewpoints around 60F ahead of the front beneath 8.0-8.5 C/km midlevel lapse rates. Semi-discrete cells evolving near and south-southwest of the Peoria area will ingest this stronger buoyancy and likely be the most intense across the Watch area -- from the general area around Peoria east-northeastward toward the Pontiac area and farther east-northeast toward the far south suburbs of Chicago and adjacent far northwest Indiana. With effective shear around 45-55 kt, supercell structures will remain possible. The Lincoln IL VAD wind profile indicates slight veering of winds with height above the ground, though with ample low-level speed shear, supporting around 200-250 m2/s2 of 0-1-km SRH. An isolated tornado could occur with the most intense storms, though large hail and damaging winds should be the primary risk. Otherwise, the risk for severe hail and locally damaging winds will continue spreading across Watch 138, with the severe risk diminishing west of the front. South of Watch 138 near the front, storm coverage should remain more isolated owing to weaker deep ascent, though an isolated severe hail/wind risk may evolve from the Saint Louis vicinity into southern parts of central IL. Convective coverage is presently forecast to remain too limited for additional watch issuance. Also south of Watch 138, from east-central IL into central IN, a separate quasi-linear band of convection is evolving, and will continue developing eastward/northeastward during the next several hours. This activity will be supported by gradually moistening inflow (surface dewpoints rising into the lower 50s) yielding weak buoyancy. Effective shear around 30-45 kt, combined with 30-40 kt of flow around 1-2 km above ground, may support semi-organized convective structures capable of locally damaging wind gusts. Weak buoyancy should minimize severe coverage such that additional watch issuance is unlikely. ..Cohen.. 04/10/2017 Link to comment Share on other sites More sharing options...
andyhb Posted April 10, 2017 Share Posted April 10, 2017 Deviant storm motion seems to be enhancing the low level SRH into that Peoria storm, with a noticeable increase in inflow over recent scans. Would help if there was a bit more backing to the surface winds on the mesoscale though (i.e. have a stronger/deepening surface low). Link to comment Share on other sites More sharing options...

Chicago Storm Posted April 10, 2017 Share Posted April 10, 2017 Decided not to chase today, and it was a good decision. There ended up being too many issues in the end... The main supercell that has moved from near MQB to PIA to PNT has obviously been the storm of the day, and has been a nice hail producer. Link to comment Share on other sites More sharing options...

ILX picked it up UPDATE ISSUED AT 1119 AM CDT MON APR 10 2017 COMPLEX FORECAST SCENARIO ACROSS CENTRAL AND SOUTHEAST ILLINOIS TODAY. A COLD FRONT, CURRENTLY APPROACHING WEST-CENTRAL ILLINOIS, IS STILL FORECAST TO PUSH EAST OF THE AREA BY LATER THIS EVENING. MOST GUIDANCE STILL DEVELOPS A LINE OF SHOWERS/STORMS ALONG & JUST AHEAD OF THE FRONT THIS AFTERNOON. HOWEVER, NONE OF THE CURRENT GUIDANCE HAS A VERY GOOD HANDLE ON THE PRE-FRONTAL CONVECTION ACROSS ILLINOIS AND MISSOURI. THE THICKER CLOUD COVER AND SLOWER WARMING RESULTING FROM THE ONGOING CONVECTION CERTAINLY HAS THE POTENTIAL TO MINIMIZE THE DEVELOPMENT LATER TODAY Link to comment Share on other sites More sharing options...
