Dropped to 11.6.

Thought this was interesting

2002-03 would be nice

13 for the low here.

We are continuing to see a fairly marked south shift with tomorrow's system in the short term. Will be a close call for the PIT crew.

    The latest HRRR now has snow into Allison Park in the North Hills, but rain for Pittsburgh. It will come down to nowcasting tomorrow morning for exact impacts neighborhood by neighborhood.

    Will be tracking exact surface temps versus models tomorrow morning. If the HRRR is a little warm, as it often is in its extended range, then we should know pretty early on if this will be more snow or more rain for this area.

    It looks like the water influenced LI temps this morning?

    Most of us are between 16 and 19 degrees off the mainland.

    13.1 in Muttontown for the low & 17.3 in Syosset for the low.

    Wonder if that has any down stream effects to the coast? Will be interesting to watch

    Imagine if any of us lived in the western UP of Michigan. A disappointing short term trend there for sure.

    Right exactly. That’s a big change in the short term.

    They average 150-200. I doubt they are upset.

    Okay, let's rephrase - imagine if any of us were there only Tuesday to Wednesday this week. Rug would have gotten yanked out from underneath us with that short term trend.

    HRRR is spitting out 2-5 inches around the area and now I see the NAM

    The NAM is completely missing this band of snow over central Ohio currently:
