One thing ive noticed this week is the AIFS has been horrible with rad cooling over the snowpack. Its a little surprising, given it generally outperforms with regards to temps. But, something is off with a deep snowpack.
This morning it was close, but Tuesday and wedneday mornings it was off 10+ across alot of the interior. All models can struggle with it, but the euro op was alot closer. I suppose it could be a resolution issue.
