I agree with them that this is not over.

in the coming days and interests should check back on the forecast frequently.”

Nah, they're just looking for clicks! Lol

Assuming we can't get the cold to move in fast, next week can work if the vort can be delayed enough for the northern stream to come down and push it south. How could that happen? Well, closed lows have a tendency to slow down and meander a bit without a strong flow and most modeling is showing a closed southern vort that is slowing. The 18z Eps and operational Gfs are hopefully onto this slowing, which has brought snowfall further south on both runs.

This is a low probability event for most south of MDT, with a start as rain for certain, so it would be, at best, a changeover to paste. But there is time, which may be the best feature at this point. Lol

Let me take a momment to admittedly misuse the Eps because I'm lazy. That said, %'s did increase as well. 12z on top, 18z on the bottom.

We are on the same page. I was just looking at the 18z EPS & the snow map did indeed increase a bit.

The mean low did tick south east a bit & was slightly stronger at 18z.

The ICON actually has better verification scores than the GFS this winter. I’m not sure what to think about this storm. The only logical thing to do is to wait until the NAM is in range. emoji23.png

That's a whole new set of problems right there.:wacko:

Gfs finally showing what I've been waiting for to believe the weeklies' great pattern. PDIII. There are 2 snowfall maps attached because, like PDII, it's long duration (2 days), so you need to ADD TOTALS FROM BOTH MAPS!

Where do I sign for PDIII on this 6z GFS run. You weren’t joking around with this long duration storm that it shows. This pattern is capable of producing events like this. Hopefully it holds & gets some company as the other Ops get in range.

Here’s the snow map for the PD storm 3 day period so you don’t need to do @mitchnick ‘s math.
