Highway situations ought to be significantly better in these areas in the direction of the tip of the day and on Christmas Eve (after sundown).
- This implies most of the metropolitan areas will finish with an ice storm tomorrow at midday/pm

The Euro has been very relentless in pushing southwards into metropolitan areas by midday or early afternoon tomorrow. By 4pm there’s a southerly gradient of about 4 mbar from Eugene to Olympia. It could possibly take the chilly out of the subway. It is going to be fairly a battle between the receding chilly air plenty and the surging southerly winds, however I am conservative and do not assume it should occur till the night on the jap subway. We’re assuming. So we’re predicting a good bit of freezing jap metro tomorrow.
