Caution, caution.........................

#1 Postby Anonymous » Mon Jan 05, 2004 6:07 pm

Lets take this "arctic outbreak" one day at a time, everyone.




Okay folks it was 74 yesterday in the DC area, even here in Woodbridge VA.

Today it hit 47 degrees. Okay, thats still 3 to 4 degrees above normal.

I am extremely disturbed when I see our forecast temps for Woodbridge into next weekend.

I am very glad you allow disagreements on this board because I am going to be a very, very active dissenter. I love these WWBB types----I should be on their board. Wetter Kerl was one of the very best!! :) He always QUESTIONED SNOW and COLD!!! We need more of his kind here!!! There is nothing quite as good and healthy for a community----be it a real-world community or an Internet community----than a good old-fashioned dose of dissent.

You know folks I have seen all your exciting teleconnection-related arguments-----But at the last-----It will be actual temperatures and actual weather observations that will determine whether all the wild, way, way, way too overly-excited talk about super-cold outbreaks and tremendous amounts of snow are really going to happen.

Yeah I am getting skeptical in my middle age-------I know life is no smooth ride.

Anyway---yes---I am becoming most disturbed, because I am seeing a rather mild arctic intrusion here in the Mid Atlantic.

Yes, we are progged to hit the teens for overnight lows this week, HOWEVER-----WE are also progged to be in the mid/upper 30s all week, with HIGH 40s for next weekend.

I see a lot of people whipping up all this excitement about "this will be a big Arctic Outbreak". Fine, its -15 in the northern Plains. That was their high today. The northern Plains will be very hard-hit by this outbreak. I have seen years where the northern Plains were super-cold....................but that does not necessarily mean we will be much below seasonal norms here near Washington DC.

Did you know that this weekend we are progged for light rain? WOW!!! That's BREAKING NEWS!!!! Yeah, and we WILL be in the upper 40s to low 50s!!!!!!

Okay folks, I am going to maintain this thread. I will post my highs and lows and how much rain we get in Woodbridge VA for the next 5 weeks------because I KNOW WE WILL. We will see a light snow or two------but folks, I have lived here in N VA for 30 years.

It's a meteorological fact-----IF WE GET A COOL WET SUMMER, THE FOLLOWING WINTER WILL NOT BE EXCESSIVELY COLD for northern VA. We will see MINIMAL snowfall. Take it or leave it---THIRTY YEARS' living here has taught me all too well.

I have NO doubt that the northern Plains will see severe cold this winter-----It would not surprise me to see those folks endure all-time RECORD cold this winter. But Woodbridge will be LUCKY to witness one single high temperature below 20 this winter---with or without clouds or rain or sleet, FRZRA or snow.



Okay---------


Jan 2 was in the 60s

Jan 3 was 73 low 60

Jan 4 was 74 low 47

Today Jan 5 was 47 (Yawn---I'm really impressed--that was 3 to 4 degrees ABOVE average!!! That is laughable---You call this an ARCTIC FRONT?)





Everyone in the southeast and Mid Atlantic, I very much hope it snows a lot-----But in the true spirit of all fairness, I MUST insist that we all take this laughable "Arctic Outbreak" one day at a time.

You people are getting a lot of people needlessly excited over what may indeed be nothing more than just a temporary cold front,

HIGH 43, LOW 28

That is average temp range for Woodbridge VA.

If you think for one cotton-pickin' moment that highs in the 30s in Woodbridge VA/ Washington DC constitute the effects of Arctic advection here, then I say you are completely out of your frickin' mind!!

I am obsessed with winter in wintertime, and I know an ARCTIC OUTBREAK!!!! I have been here since 1969 and I know what the f--- a genuine Arctic Outbreak is for northern Virginia!!!!

This is not it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


If any of you on this board are going to insist to me that northern Virginia will experience an Arctic Outbreak, then that doggone high temperature had better well be at least in the low to mid TWENTIES!!!!! With those highs, lows in the TEENS are fine by me.

If we are progged to be in the 30s all day, regardless of lows in the teens or twenties, then don't go calling this an Arctic Outbreak!!! Be SPECIFIC!!

As of today, the northern Plains region IS CERTAINLY enduring a bona-fide Arctic Outbreak! Their highs are in the negative single-numbers to the negative teens!!!! Yeah that's COLD stuff!! The genital organs have done already frozen and fallen OFF OF the proverbial brass monkey up there!!

But your so-called "Arctic Outbreak" is being modified as it INCHES south and east. Some years are like that here in Virginia. The snowpack in the East is now minimal to nonexistent!!! The mountains stand in the way of the Northern Plains' Arctic Outbreak ever reaching Virginia. That's just the way it is this year!!!


I will be maintaining daily highs and lows on this thread.

CAUTION folks.........IT'S NOT AS COLD AS YOU THINK here. We are STILL ABOVE AVERAGE..........from your laughable Arctic Front. This weekend we will be well above freezing...........with a good chance of RAIN.


Some arctic front................


Please everyone jump in and please do dissent with me!!!! Don't everyone jump in at once!!!! LOL!!!


-JEB.....47 degrees and snowless and still above average!!! Some arctic front.........

It was an arctic front. It may have modified by the time it reached you. Case in point....

Here in Omaha...
Jan 1: 52/29 (average 31/11)
Jan 2: 60/29

not a big deal arctic air mass. it came in at the wrong angle, and will kill snow chances, except for the lakes

It will get cold, but it may be a step down process south of DC. pattern is setting up, and trough should retrograde west with the axis about 85 - 90W per HPC. Check Drag's update out of BOX this evening......he's getting excited and salivating (or some such thing) over the upcoming cold pattern. Let's see if it STAYS cold the next 3 weeks. Still warm in Melbourne FL, 82 today 8-)

I did not state that there has been no arctic air in northern Virginia since 1969, DT.


Jan 21 1985 An arctic front moved through Woodbridge VA. We received 2 inches of snow from it, the low fell to -2 degrees, the high was 2 above zero, then the following night we hit -14.

I know the weather in my region!

Places like the northern Plains will be very cold this winter.

The Mid Atlantic region will not be below average in temperatures this winter.

You, DT, and other so-called professionals on this board are falsely raising the hopes of people on this board. You are asserting that there will be a so-called "MECS/SECS" storm when in fact there is more than abundant evidence that it will be too warm in places like Washington DC and south.

I find that unreasonable. There are some people here that are leaning on your every word about snow chances because they rely on you and weather experts such as yourself, to "give them hope for snow".

That's natural, but PLEASE make certain that you know the weather conditions in the regions you are forecasting for. It will be cold enough for snow Wednesday and Thursday, but NOT this weekend and definately NOT Monday and Tuesday next week.

Okay, so you are a weather expert. Then ADMIT the arctic front will MODIFY before it crosses the Mid Atlantic. Please don't falsely lead folks on to think there could be snow when you know it will be too mild. You are supposed to be the "expert" aren't you?

Sure, the Northern Plains will be very cold this winter, it does not take a trained met to see that, the Northern Plains are climatologically favored to be bitterly cold. But I say that most, if not all, cold fronts or arctic fronts this winter will modify before or as they cross the Mid Atlantic region.

Even the big cold shots modified when they came in to the mid-atlantic, otherwise your temps would have been much colder. I don't that's much of a statement to say that fronts this year have been modifying when they get to the mid-atlantic. That's what cold fronts always do.

Valid point, Feanaro. Fronts always modify.


I just feel shortchanged because all these weather experts here were leading us on to expect "all this really cold arctic air is gonna move south". They have been leading us on to think we were going to get all this really cold air. Then I thought I would see a nice high of 25 degrees, because the weather experts here claimed we were gonna get this "arctic front". For Woodbridge VA, a normal high temperature means approximately 42 to 44 degrees in early January, and that normal high temperature goes UP as you progress through the month. A "normal" cold front for January will generally bring our region highs in the mid to upper 30s, with lows near 23-27. Under that regime, storms can still bring us RAIN.
An arctic front should bring Woodbridge highs in the low/mid 20s with lows in the single digits to the teens. Under that regime, we can get hammered by snow.

In all likelihood, the front was truly arctic up in the northern Plains and Midwest, but by the time that poor overheated puppy reached the hapless Mid Atlantic, the front had modified to a point where it had degenerated to nothing more than an ordinary January cold front that will bring us highs in the upper 30s. We might eke out lows in the mid/upper teens. Then, this poor excuse for a January cold front (Arctic front my @ss!!) will die out and we'll have more upper 40s to low 50s by early next week!!!! Some cold front!!! Arctic Front? Don't make me laugh!!!! Highs in the upper 40s by Sunday?!! Ha Ha Ha Ha Ha LOL LOL LOL LOL !!!!!!!!!!!!!!!!!!!!!!!!!

I don't even need a coat outside in 47 degree weather with sun and light winds!!! Some cold front!!!! LOL LOL LOL

Jeb,

As I had noted on December 24, "From an examination of years in which patterns were approximately the same as those that prevailed during the most recent 10 days of December, one has seen the cold come in in pulses with the climax coming several weeks down the road... A thaw had typically set in toward the end of the month. For what it's worth, the best chance for extreme cold would exist in the January 18-25 period after which a noticeable warmup would commence."

The timing of the first significant frontal passage toward this pattern (1/3-5 was highlighted) did not mean that I was expecting the polar vortex to drop right into the East or for record cold to cover the region.

The air mass coming in is very cold (though not extreme) and has the potential to bring single-digit readings to the big cities of New England if the European Model is right.

To illustrate the example, let's examine the 850 mb temperatures for Thursday 12Z (January 8) at a select number of cities:

Boston: -25C
Charleston: 1C
New York City: -19C
Philadelphia: -17C
Richmond: -7C (but -13C on Wednesday)
Washington, DC -11C (but -16C on Wednesday)

The lowest readings for the Wednesday-Friday period on the MOS are (and these might be lowered when the new MOS is released, especially if the ECMWF figures bear out):

Boston: 6
Charleston: 22
New York City: 16
Philadelphia: 18
Richmond: 18
Washington, DC: 19

Per my earlier discussion and also based on the unfolding synoptic pattern, I do not believe that these readings will be the coldest we will see this winter and I believe that there will be a period of severe cold close to around the timeframe I had outlined (perhaps punctuated by a significant storm as highlighted by one of the analogs for the evolving pattern).

The cold air mass now invading the region is the start of what will be a cold pattern. While there may be some brief warmups, such warmups will likely be modest and then broken by a fresh incursion of very cold air.

While January 8-14 will be cold, I believe January 15-21 will be colder and it is possible January 22-28 could be even colder if the January 18-25 period of severe cold materializes.

I do not believe Washington, DC will reach the mid and upper 30s (by that I mean let's say 37 or above) in the Wednesday-Friday period nor do I believe it will reach the high 40s (47 or above) on Saturday or perhaps even Sunday. Upper 40s or lower 50s the coming weekend in Washington, DC? I could be wrong, but I doubt it.

This is a big Arctic outbreak even if it is not extreme. The air mass is of Arctic origins, it will cover a large area, and the air mass will be by far the coldest so far this season.

Let's see where things go. I believe we are at the beginning of an increasingly cold pattern that could culminate in a period of severe cold (especially if the PNA+ and NAO- work out) with some prospects for important snowfall.

With the strong frontal passage today, the first die has been cast and it has been cast consistent with the pattern evolution outlined on December 24. Whether the analogs on which that evolution is based derail remain to be seen, but so far both the ensembles and model guidance suggest that everything remains on course.

Great post Don. I like your balanced approach, you always post informative and easy to understand threads. Keep up the good work, and I certainly hope it pans out. I love cold weather and am hoping for some snow myself.

Thanks.

We'll see what happens. I'll try to verify the numbers for some of the big cities for each of the weeks to see how this has worked out.

Also, I saw in another thread Gary Gray's latest discussion. As always, it is an interesting and informative discussion and I have little disagreement about the January 9-10 event.

However, while he has literally interpreted the computer guidance for what it currently shows, several points are in order that could change the equation down the road, particularly in the January 12-22 period:

1) a more active Southern Branch of the jet stream interacting with an expansive area of cold
2) the development of a PNA+ and NAO- that allows for greater digging of systems
3) the progress and impact of the Kelvin Wave that was mentioned yesterday by SF here and HM at WWBB

It is important to note that the model solutions de jour are not written in stone. They can change and often do change as patterns evolve. Most recently, it took some time for the models to grab onto the idea that the big pattern shift now underway was about to occur. They trended toward that solution on a run-by-run basis until they reached consensus. Hence, in a cold pattern with the possibility of an active Southern Branch, it is risky to lock into place a model consensus against big storms that could change radically over the next week or so especially as that consensus was reached at a period of transition where the models can be especially prone to error.

I'm not saying that there will be a big storm but the fact that one of the analog years had one (in the latter part of the timeframe I mentioned) and the hints seen from time to time in various members of the ensembles are reason to be wary of the prospect now that a cold pattern is unfolding.

DINGBAT

[quote="Jeb"]It's a meteorological fact-----IF WE GET A COOL WET SUMMER, THE FOLLOWING WINTER WILL NOT BE EXCESSIVELY COLD for northern VA. We will see MINIMAL snowfall. Take it or leave it---THIRTY YEARS' living here has taught me all too well.

exactly DT

saying something like that is about as smart as drinking a dog sh!t slurpee and expecting it to taste like a fine wine.
