welp pretty much all of 12z suite says this low will cut well west if it manages to amp up... as in west into Michigan... would have most of us with temps near or below 0 Saturday morning and into the 40s/50s by Sunday afternoon... would not be a good track for Boston area... First up though is holy cold for Friday morning...

MDT has a very good shot at hitting -5 ... I hope I never experience a Jan 94 broken record though of -23!

The idea of a cutter and a snow to rain scenario wouldn't bother me so much if it were a pattern changer to a spell of above normal weather, but it's not. Here's the temps for Sunday night through Tuesday...

 

  • Sunday Night A chance of snow showers. Mostly cloudy, with a low around 12. Chance of precipitation is 30%.
  • Monday Partly sunny, with a high near 22.
  • Monday Night Partly cloudy, with a low around 8.
  • Tuesday A chance of snow showers. Partly sunny, with a high near 24. Chance of precipitation is 30%.

That's what has me wondering if the models are even handling things correctly.  If timing is slightly off on one or more of the components, how much will it change things over the next few runs? Could be slight changes or could be significantly large ones.  I have not seen what 12z euro is doing at 500mb yet, but the other models have energy digging southward along the west coast Friday night to Saturday morning.  Northern stream energy then swings into the Northcentral US on Saturday and grabs just a piece of that energy along west coast, leaving the rest behind.  This is when the 12z runs now amplify this piece of energy to become Sunday's system that tracks well to the west.  Then once through we are right back into the cold.

First off, my condolences on your loss.

 

The January '94 cold snap was one of the most memorable weather events of my life. I was living in Albany, NY and we were under a snow emergency. My car wouldn't start and ended up getting towed by the city. I had to wait several days to pick it up because it wouldn't start in the brutal cold.

Suspicious of the warm up this weekend, only because of what we saw last year many times. The cold air was relentless to scour out and we were left with awful icing situations in Hershey when I lived there. I care this weekend because the farm show has a huge event we are covering called Motorama. Would like to see it warm up but again I remember how our temps never rose while areas north and east were in the 40s and we stillhad freezing rain.

I know we were sweating out the mixing line creeping north and far eastern New England was raining during the mid range leading up to our most recent event. That of course turned into an 8-10ºF fluff snow for the southern tier and dust for the northern tier. We also had crazy run to run changes considering the range with that as well, so I wouldn't write any options off attm. The big factor I see modeled attm is the positioning of high pressure to our east instead of northeast, that coupled with the strong high dropping into the north central from western/central Canada leaves us quite vulnerable for the low pressure to cut on us. 

 

Upper levels of this potential system don't look really particularly impressive, nothing closed at 500 or 700mb and a pretty weak 850 representation that is progged to go NW of the area but nothing thats going to drive >10ºC 850 temps over or anything. So if there's decent WAA precip well ahead we could certainly see a good front thump. The Euro certainly suggests as much, having >0.5" of front end frozen QPF for the NW 2/3's of the state and a bullseye of 1.0" frozen QPF in west-central PA.

Mag any thoughts on squall line?

 

Looks like we have a couple different lines moving through. And the first line of squalls is here currently with visibilities to about 250-500 feet just like Saturday... wow!. What looks to be the main line is off to the west yet just arriving into Cambria County.

Two questions...

 

First one: Will these snow squalls survive their trip across the mountains like they did on Saturday night, or is this set-up different?

 

Second one: After this weekends possible rain event, we go back into the deep freeze for a good portion of next week. Is there ANYTHING on the horizon that would indicate we break from this current pattern and get some mild weather? Per the GFS, is appears that cold weather will be the rule through at least March 6th.
