I don't think anyone is completely flipping out . Highs in the 70s and two beautiful days are a straight wishcast based on the available guidance.
Will it be 40s, no I'd bet against record low afternoon temperatures. Probably 60s for maxes but what the bulk of the afternoons are matters.
You keep mentioning "one op run" and folks that actually look at models can tell you it's on all of them. It's a weather forum, we discuss the model data.
