The 12Z Euro is much cooler than its prior run and has colder than normal for much of the SE 4/12-4 thanks largely to a stout -NAO. IF it were right, even
@pcbjr would be flirting with a very pleasant low near 49 on 4/13 and the Masters 2nd-4th rounds would be pretty chilly. However, caution is advised before believing this because:
1. It is an operational model looking out 7-9 days, especially since it is much cooler than the prior run.
2. The op Euro like most models has continued to have a solid cold bias as per this from Radiant:
"Our warmer outlook is influenced by what has been a significant cold bias within the models, which is evident in the Monday-Thursday verifications from Monday’s runs. Our forecast on Monday accounted for the bias, and for the past four days missed too cool by a total of 0.7 GWHDDs. All other models had larger errors: GFS OP missed by 1.3 GWHDDs, GFS EN by 6.6,
Euro OP by 6.6, Euro EN by 8.0 and CAN EN by 14.0."
