Thursday Afternoon Model Update

10/20/22 Thursday 1:15 pm
It is more common than not for models to show different storm tracks in the days leading up to the arrival of the storm. Timing also starts to slow down. I have not seen big changes in the arrival time of the storm, but there was a noticeable difference from last night’s to this morning’s model runs. The Euro, Canadian, and GFS are all tracking precipitation further south. By no means a miss, just a different spread of the precipitation. As I said yesterday these could be anomalous runs and I will wait to make any changes in my thinking for at least 24 hours.
I had a strange request for the Japanese model forecast (JMA). It is not a model I use very often for precipitation. I use it more for tracking high-pressure ridges and low-pressure systems. But I will add it to the lineup.
