Valid 130102Z - 130230Z The severe weather threat for Severe Thunderstorm Watch 638 continues. SUMMARY...The risk for damaging gusts and isolated hail will continue this evening. DISCUSSION...As of 0055, a couple clusters of strong to severe storms were ongoing over parts of southern NY and eastern PA respectively. These storms have produced several reports of wind damage and hail over the last couple of hours. Recent HRRR and radar trends suggest these storms should remain capable of isolated wind damage and hail into western portions of CT tonight. Farther south into southeastern PA, new convective development was noted west of Allentown. Likely in response to an increase in synoptic support from the approaching trough, these storms may continue to intensify and pose an isolated severe risk into central NJ over the next couple of hours. 1000-1500 J/kg of MLCAPE and 40-50 kt of deep-layer shear would support a risk for damaging gusts and isolated hail if storms are able to organize. However, with the loss of diurnal heating, there remains some uncertainty on if storms will be able to mature prior to nocturnal stabilization. ...Lyons.. 08/13/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!_vBATnigWWG_9R9opq2s3OjC-NFCxFaE_xxIk0i7_mlAo-Va95nZm4QiQEVEsNNJ37GJtqd6N= lN88UnG-_TAfd1a1Q4$ for graphic product...
