I spy lots of fall streak holes (a/k/a hole-punch clouds) on viz sat over SC. These are caused by airplanes "punching" through a supercooled layer and causing sublimation as the aggregation of ice crystals gets pulled downwards behind the plane. Share pics if you see them! #scwx

No OTD posts for another couple of days, as I continue to recover from carpal tunnel surgery.
In related news, I'm getting better at typing with one hand.

Cool, but sunny conditions will move in behind the cold front that pushed through last night. High temps over the next couple of days will reach the 50s, which is a few degrees below normal for this time of year. More details: weather.gov/chs

(🧵/3) Severe weather tomorrow:
A possible QLCS (quasi-linear convective system) will move through the Southeast Wednesday. For a QLCS to produce severe weather, it needs:
⚪️Shear
⚪️Lift
⚪️Instability
⚪️Moisture
One missing ingredient can make a big difference in the impacts.

Earlier this afternoon, we accidently included a bad snow grid in our set of gridded forecasts that go to the NWS NDFD. Obviously, the forecast of 144" was in error. The issue was quickly fixed and graphics were updated. Glad to know so many follow our snow forecasts so closely!
