January storm threat discussion #2


Ian

Recommended Posts

I think pessismism is warranted, though getting 0.6" for the winter is super rare.....even <4" is pretty hard......I think anything is still on the table though if I was issung a revision, I would put the seasonal over/under at DCA at around 5-8"

I'm about as pessimistic as they come but I don't see how we end up with less than that. It would be pretty remarkable to get through Feb without a storm that drops a few inches. I just don't think we'll fluke out before then.. perhaps at the very end of the month if we're really lucky.

If the euro is right at 240 hrs maybe we can pop a pseudo positive PNA look and have a chance after that low goes to the lakels and eventually drags a front by us. The nao at 240 hrs is postive but the AO is not. I've got some nice graphics that I hope Jason will let me post next week in pattern discussion article. Greg will be doing one so Jason might not want oen from me. I've plotted the PNA versus the nao and ao and the nao verus the ao for 4 inch or greater events at DCA.

day 10 has 7am temps in the 60's at memphis, 50's for all of va up to central new jersey, even green bay is in the 50's lol

It worries me we didn't get a fluke already....lots of winters were virtual shutouts in Feb/March.....one 2-4" would actually make me happy

That also worries me and I don't see anything in the next 12 to 13 days which puts us almost through the month. Still model forecast past 5 days aren't that good so I guess it's not hopeless but in this pattern even if they are wrong they would have to be monumentally wrong to give us much before day 10.

Matt, I saw your reference to the PV over Greenland moving east. When I look at the last three frames of the ec 500 loop, it looks like the PV in cenral Canada splits, and the two PVs are moving away from each other pretty quickly. I guess it's logical that there would be ridging around them both? If they are too close to each other would that support a flat ridge type signature between them? And, if they are ideally placed would the ridging near them promote a blocky type trough between them? Just trying to figure out some of this, and thought you, Ian, or Wes might chime in if you have time. Also, if you took the 10 day height pattern, ideally where would you like to see it progress to?

The same ECMWF that showed a negative NAO greenland block on sme runs at 240 earlier this week.

The PV over greenland is bad. We need a ridge over Greenland and a low to its south or a ridge pusing eastwrd from the west coast. Neither looks to be met anytime soon. Without one of those if gets tough to get much snow. Not impossible but not something you'd bet on.

That's true and the euro ensemble mean looks pretty warm and bleak through the run. It's got a postive nao and negative pdo thru 240 hrs.

I assume you had yours on because you alwas put saftey first, but as a warning to some of the n00bs on this board:

DO NOT LOOK AT THE EURO ENSEMBLES WITHOUT A PAIR OF THESE RATED AT OD5 OR HIGHER. THEY WILL CAUSE PERMANENT BLINDNESS!!!

Ji: Step back from the ledge. Here are some events to track;

three weeks until SuperBowl

the final three weeks of February could bring some rare snow to DC

Wes goes fishing for a month about six weeks from now.

Take a deep breath. We can do this.

<Dick Vitale>...And don't forget March Madness just around the corner, baby!!</Dick Vitale> :thumbsup:

GFS is now forecasting a monster High over SE Canda in the last week of Jan that would kill the torch for us despite the bad 500mb pattern

Larry Cosgroves new update is quite depressing. You were right when you said winter is over back in Nov...I didn't want to believe it.

sucks but there is still plenty of time to get 1 or 2 events before winter is really over. LC saying winter over may be the best thing we can have happen to us based on his forecasting this year:)

Whether he's right or wrong does not reaaly matter. His final statement about whst the super ensemble has been saying is relavent. Winter does not come to the mid lattitudes this year. He says it been. Right. From what i read here the ec ensemnbles are saying the same thing. Reality is hard to deny!!!

Just to give you guys an update, the EC ensembles still try to carry that weak ridging in the DS. The GOA low does try to lift, but it's still pretty ugly as displayed right now. My guess is anything worthwhile will wait until sometime in Feb.

Thanks for the update. Obviously there's no snow, but it's pretty nice out there right now. A good weather day for Bmore to be in the spotlight, and the next week doesn't look terrible for those of us that haven't caved to mapgirl.

How do you figure? Temp wise or storm chances? I don't see much in the way of snow chances.
