The overall severe threat is expected to be isolated and a WW issuance is not currently anticipated. DISCUSSION...Modest surface heating has resulted in surface temperatures warming to over 70 F in several locales ahead of a primary rain band, contributing to 8+ C/km low-level lapse rates (per 15Z mesoanalysis). Strong forcing for ascent associated with the approaching 998 mb low will encourage several thunderstorms to develop over the next few hours, within and ahead of the aforementioned rain band. These storms will overspread the steep low-level lapse rates/mixed boundary layer, promoting efficient evaporative cooling and downward momentum transport to support damaging gusts. Mid-level lapse rates are mediocre. However, elongated hodographs suggest that the strongest of storm cores may produce some hail, and an instance or two of 1 inch diameter stones cannot be completely ruled out. The severe threat is expected to be isolated however, and a WW issuance is not expected. ...Squitieri/Thompson.. 06/14/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!6O4gjY84uw_LDqq50lBEFRnr2haK_6QiAPtGdZp8tV2pRSbB_RMrAT2SjMbJcdDwD9wXwOu1Y= GM4Zx6a09amyr_FgG8$ for graphic product...
