MD 0472 CONCERNING TORNADO WATCH 122... FOR EXTREME EASTERN IN...MUCH OF OH...AND WESTERN PA
Mesoscale Discussion 0472 NWS Storm Prediction Center Norman OK 0112 PM CDT Wed Apr 17 2024 Areas affected...extreme eastern IN...much of OH...and western PA Concerning...Tornado Watch 122... Valid 171812Z - 171945Z The severe weather threat for Tornado Watch 122 continues. SUMMARY...Storms moving into northwest OH may intensify the next 1-2 hours. All severe hazards remain possible across Tornado Watch 122. A downstream watch will likely be needed in the next couple of hours across eastern OH into western PA. DISCUSSION...Convection has slowly intensified into early afternoon as storms move into a somewhat more unstable airmass. Stronger heating has allowed low-level lapse rates to steepen ahead of the line of convection. This will support potential for increasing gusts. Furthermore, low-level instability remains quite large, with 0-3 km MLCAPE greater than 125 J/kg. Regional VWP data shows enlarged, and favorably curved low-level hodographs, and low-level rotation has been noted in velocity signatures via region radars. Further intensification of these cells is expected over the next couple hours across northwest into central Ohio. As convection continues eastward, a similar environment is expected to extend across parts of eastern OH into western PA. A downstream watch will likely be needed by 20z/4pm EDT. ..Leitman.. 04/17/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...PBZ...RLX...CLE...ILN...DTX...IWX...IND...

Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0158 PM CDT Wed Apr 17 2024 Valid 181200Z - 191200Z ...NO CRITICAL AREAS... No changes to the current forecast. ..Wendt.. 04/17/2024 .PREV DISCUSSION... /ISSUED 0153 AM CDT Wed Apr 17 2024/ ...Synopsis... Predominately zonal mid-level flow is expected over the CONUS by D2/Thursday. Stronger westerly flow is expected to gradually shift east as weak high pressure builds over the West. At the surface, a cold front is forecast to move across much of the plains ushering in a cooler air mass. Surface high pressure behind the front should keep winds modest over much of the central US. The only exception to this may be across parts of far northeast NM and southern CO. Here, the dry air mass may remain sheltered from the cold front supporting at least brief localized fire-weather conditions D2/Thursday afternoon. Otherwise, fire-weather potential appears limited across the CONUS. ...Please see www.spc.noaa.gov/fire for graphic product... Read more
