Looks like we have one of those weeks coming up that I really hate. Dry and frigid. Crank up the heating bill and no snow to at least reward us for dealing with the cold.

Don't worry, only 5-6 more days of bitter cold, then the warm air arrives just in time to rain early next week. Hopefully the trend for more progressive less amped continues as we draw nearer in time. Realistically that is the next storm to track outside of the arctic front Wednesday and snow showers.

.LONG TERM /FRIDAY NIGHT THROUGH MONDAY/...
Northwest flow snow shower activity will continue at least
into Friday night before the snow machine shuts off sometime
Saturday. Friday may be particularly cold with single-digit max
temperatures. A brief respite from precipitation will be seen
Saturday night into Sunday, before a more organized storm system
approaches for Sunday night and Monday. Enough warm air may be
pulled north to finally get temperatures above freezing by
Monday, and also to allow for liquid precipitation.

I'll take under.  The lakes are freezing over which is our only source of moisture in this pattern.  

Maybe its just the back to work January 2nd post holiday season blues talking, but I was thinking the same thing. We really need to keep the cold around, but get into a more gradient type pattern, or get some blocking on the Atlantic side to slow the flow down a bit. The ocean storm for the 4th is a good example. Had the flow not been so fast and progressive, probably would have seen a clean phase of all the streams and a pretty big storm that would have at least thrown some snow to us,

I say big snow at the end of the month puts us near or over. :snowwindow:

I like the optimism, gut says take the under, but it only takes 2-3 moderate storms or one big one to put us at or above.

i'll go under as well. Simply because the pattern, though cold right now, is not favoring precip. The end of the month looks slightly more mild as well.. So if it is going to snow, I think we need it in the first half of the month.

The nice thing is in the dead of winter the pattern doesn't need to be perfect to produce snow.

Mondays storm on GFS has storm going further north and mostly rain.

Canadian has storm trending South and therefore snow. 

Will they come together in our benefit? I say the odds are maybe 20% ?

Cold and dry, warm and wet. We should know the drill by now.

 With such an powerful system forming now, anything is possible. Early weekend we will start figuring this out

-8 in my backyard this morning, brutal cold.

Yeah I noticed a range of +6 to -7 on my car thermometer this morning driving into work.

Friday may not see highs out of the single digits, could prove to be the coldest day of the winter. Irritating if we do end up with a snow changing to rain setup Sunday night into Monday, but I've seen it happen countless times before were the cold retreats just ahead of a precip event. My post several days ago about the likely next time we would be above freezing being a few hours before the next precip event was only partially tongue in cheek. I will say this though, with snow cover and the long duration of brutal cold, ground temperatures will be slow to respond, so initially even if we see snow to rain it's going to make for some dangerous travel conditions.

More reason for the under estimate. MJO heading into a warmer phase. Could still get something from this, but will be challenging.

 

Yeah, the only thing that might help a bit is the significance of phase 4,5,6 is pretty low this time of year. I'm hoping the wave stays fairly weak too, at least through the bad phases so that should at least help from setting up an overwhelming warm signal. Of course that doesn't preclude something else from doing so. If the cold stays locked in to the North of us in Canada and we average close to normal then we still have a chance if a storm takes a favorable track. My big concern would be if Canada gets all the cold blasted out via the PAC Jet, then we are probably looking at a minimum of 2 weeks after the cold moves out to get things right again for snow around here and by that time we are heading into Feb.

Such a waste for that beast of a storm to be out in the ocean. It's a shame the whole thing didn't get its act together sooner, nice negative tilt by Mississippi and I could in-vision it tracking up the coast just inland and blasting us with a Blizzard.

We may crack 20 today. Anyone know the last time we hit 20?

i know the all time consecutive streak is like 10 days. We have to be pushing it.

If we don’t hit it today, we likely won’t again until monday.

Just a cool side note to track, in what is otherwise frustrating period - esp if the precip arrives Monday in the form of slop

The temp just jumped from 1 to 8 in one hour.

Christmas Day had a high of 32°. Its been an impressive streak of cold.

Oh Canada!

Here is just for Monday system on GEM, the warm tongue is pretty evident and it shows in snow totals. GFS went South, but the cold air is retreating, so its a double edge sword. We need the storm so disjointed and south that qpf is limited, otherwise WAA easily scours out cold. I'm not sold on that just yet, just saying what the models show.

The National Weather Service really might want to issue an blizzard watch for Western PA, some localized areas downwind of power plants, like the nuclear plant out in Beaver  need to watch out and be prepped.  I remember a decade ago being toured the weather service and showed me the fallout model they have

We need a high pressure to show up just to keep some cold air in. I'm not sold on this set up for anything more than maybe 2-4 slop storm. Honestly I just want it to get warm up a little so I can get rid of the sheet of ice on my driveway and clean up my car a little. Not to mention taking down my Christmas decorations.
