lol- how well did our last "locked" storm work out? 6z gfs is taking the bigger storm so far n-w that it's starting to have the look of front end snow. Just gotta watch that 1031 hp over ME. It needs to end up being west about 150 miles. Feel better?

You don't seem to understand how things work around here.

 

If it's a snow scenario, it's NEVER a locked system.    If it's rain or a cutter, you can lock that sob in at 180 hours.   Once it goes from a snow situation to a rain storm, you will almost never get it back.

Good drill down. I was broad brushing the fact that nothing is locked until it's over but in a very general sense. A cutter is a locked rain event. It's chicago that sweats the details. We just don't know how much rain were getting and if it's going to be 40 degrees or 60 degrees. None of that means a damn thing to us of course.

Since this great blocking pattern seems modeled to persist into April, it got me thinking.... Has there ever been a scenario when a suite of LR models feature both a snow storm and a heat wave (maybe 80+)?  I'm thinking one last good kick in the nads would be a bust modeled storm (in the short range) and dead-nuts verification of a modeled heat wave (in the long range).

In March 1990, when I was living in the DC area, we had a stretch of 5 days of 80+ temps including 2 days in the upper 80's.  Within a week after that, we had two accumulating snowfalls.

Doubt if the models ran out long range enough to show both scenarios in the same model run.

LOL - Models never bust on heat waves either!

This is so incredibly frustrating, I give up. Wake me up in November. Even in good patterns this year just whatever can go wrong does. We have no +PNA plus we have a block but in a bad spot, ugh. 

You just pointed out 2 reasons that it's not really a good pattern, especially given its March.  We need a great pattern to have a good chance this late in the year, and right now it looks like some factors are not lining up the way we need.

wow, that's wild. thanks.

 

I can't remember that far back.

Still surprised how many will not accept that 5+ day models operate to show just about every and any solution possible rather than locking in on the highest probability and sticking with it until compelling information is presented that necessitates a change.

an operational model run is just one simulation, what you are looking for we have in the ensembles, they give a better idea of what the highest probability is if you know how to use them correctly.

That is an odd translation of human behavior onto a purely numerical computer model.
