What the latest 12Z HRRR-IR Satellite "Evolution" Simulation 4cast imagery may look like as Hur. Isais moves inland & becomes post-tropical & heads N-NE -think the large cirrus cloud shield will enter SONT Sat. AM with showers moving in later that eve thru Sun. (L. Erie area) #onwx #onstorm

Latest hourly HRRR run -Radar + cloud cover (>50%) for the rest of the day till midnight. It remains somewhat unstable/unsettled mainly in NE/EONT for the day with scat. pop up showers, elsewhere mix of sun/cloud. #onwx #onstorm

One last one before I start my day & slay more dragons 🐉. I combined Graupel production & LTNG⚡️ (cause they go "hand in hand") for the day, so the risk is there for some cells to produce hail & LTNG⚡️ Have a great day! #onwx #onstorm

Latest hourly run of the HRRR- Radar + CAPE 4cast till Midnight. It remains unstable, cooler air aloft , enhanced lake CAPE, approaching TROF-all supporting the development of scat. showers/storms, mainly in SC/EONT. #onwx #onstorm
