@Chazwin just addressed the well forecasted upcoming cold. But if you still have doubt, you can go here to see as far back as the 18Z 3/24 run and go forward from there:

Every single GFS run since had the cold snap well modeled. You can also look back in the March thread back to these two from
@SD on 3/24 that now make him look like a guru:

I had no idea you moved. Where the hell have I been? Where is the Southwest did you move to? New Mexico!

I even owe an apology to the Crazy Uncle because of this post I also did about the 12Z 3/24 run:

I said:
"More about the cold biased Crazy Uncle: 12Z on 4/3 has RAH well down into the 20s, upper 20s at ATL, and upper 30s down to about Hogtown (I don't believe it,
@pcbjr , as it is far out on its own and it has a bad cold bias): it has a 1040 Arctic high parked over the SE...not going to happen!"
Well well well, RAH is progged to get down into the upper 20s, ATL near 30, and
@pcbjr 's Hogtown upper 30s. Other than having the high too strong by ~5 mb, that Crazy Uncle run was nearly spot on and I was wrong to not believe it would get that cold. Of course, that doesn't mean it doesn't still have a bad cold bias.
