finally!

Lol ya but pretty much right at climo wise. Also looking at the GFS this morning the trough is sharper and that's exactly what we need to get the cold air and moisture in here to possibly see our first flakes of the season. Also this pattern that is setting up is a thing of beauty. Wow seems like we have not seen a pattern like this for about 2 years. Right through Halloween we are looking at an ideal pattern for a stormy cold pattern for this time of the year.

Well been working alot so haven't had much time to post. But working on another .10" of rain and more to come today. Next couple weeks looks like prime setup for miller b rainstorms. Very well could finish out the month of Oct on a wet pattern with near to above ave rainfall.

 

Finally glad to see 30s in the forecast. Even though not forecasted tomorrow night 30s seem possible along with wedsnesday morning. Then the temps go downhill to atleast sunday.

 

 

Wow! some really cool/cold temps forecasted for next week. Current forecast for my area has highs in the low to mid 50s; with sunny skies. If the winds can go calm we would definitely be looking at a chance of at least a light freeze if not a hard freeze.

Friday morning and Saturday morning are the days to watch. DPs are forecasted to be in the mid 20s both nights. So with near prefect conitions for radiational cooling a hard freeze(25-30degree) is more than likely. This time next week the official growing season will be over.

  It's like clock work down here.  Come Oct 20th, the cold air appears, way, way more years than not.  Climo is an amazing, wonderful thing :) 

  Hope you are right about the rain.  I've eked out .3 over the last few days, and need lots more than that.

  I like how the GFS keeps pushing moisture up into strong Atlantic highs.  I'd love to see a lot that in Jan. and Feb. Tony

Well looking at the pattern and the GFS and the Euro the rest of the month is going to be downright cold for this time of the year. Again how I wish this pattern was in January because we would be rocking. Anyway the period on the Euro from know until the end of the 10 days looks below average with a low rotating along the bottom of the trough in the East. Would mean some nasty cold weather more much of the SE and possibly some snow in the mountains. This new low just showed up though. On the GFS it looks like right through Halloween we are going to see very cold air for this time of the year. We have several shots of reenforcing  shots of cold air in the time period. What is amazing is how well the GFS and the Euro agree on this pattern right through the end of the month.Should be a fun couple of weeks because the NAO and the AO look to go very positive in the first of November.

Mother nature knows what she is doing. If climo has come and gone with no frost then I'd say be worried. One thing Ive notice is the STJ has been pretty active over the last week or so. IF that continues with the deep polar vortex that is suppose to develop in S. Canada then the miller b type storms should have no problem getting moisture.

Dude look at the pattern. The pattern that is suppose to set up it will too hard to pinpoint what is going to happen 72 hours out let a known further with the amount of s/w engery rotating around the PV. All it takes is the right placement of a couple s/w and a miller b bomb will be going up the coast. But chillax some I'd say a high probablility that you and other mountain folks will have the first flakes by the 1st.

Hey sorry if i am a bit excited about this upcoming pattern just because it is going to be our real first taste of fall/winter feel to it. Also just thought I would post what I was seeing on today's model runs because no one else had yet. If you feel like I am over posting then please let a mod know about your concerns. Yes there are a couple of chances for some high mountain snow for the mountains over the next 2 weeks but slim at best right know but the GFS and the Euro have been pretty consistent showing this favorable pattern for a while.

My bad that wasnt my intentions by the post I made.  But you're not the only one that is excited and very optimistic about this coming winter. :snowing:

Hey no problem. I agree this might be a good sign for the upcoming winter but what sticks out at me is that we have not seen a two week pattern like this in over two years. Really wish this was in January but hey enjoy it while we can who knows what winter will bring.

WGHP going with lows in the 20s next weekend in the Triad.

 

 

Yeah, well they also went for this for today.

 

 Lows will be in the lower 50's by morning, but temperatures will warm up nicely through the day, courtesy of a southwest breeze.  Mostly cloudy skies stick around until the dinner hour, and highs will be in the lower 70's.  Our rain chances will be quite low, around 20%, and that is mainly for the southern and eastern end of the Piedmont.

 

We had 61 for an airport high with drizzle all day.

Based on that, the 20s next weekend could be anywhere from the teens to the fifties.

Weather Channel is going with a high of 40 with rain and snow on Wednesday here in Boone. Not sure how I feel about this, nevertheless I couldn't be more excited for my first winter here in Boone!

 

I'm sure everybody up there has already informed you of this, but Raysweather is your best friend when it comes to weather for the high country.  He manages the micro-climates of the high terrain much better than the big fellas like TWC and AccuWx.  Anyway, he too is mentioning flurries or snow showers for Wednesday:

There is definitely a chance of a few snow showers/flurries in the mountains of North Carolina on Wednesday.  It should be interesting to watch in the mid-week time frame.

 

Then, cold air funnels in with our first frost and/or freeze possible by the end of next week.  Lots of cold air, now only if we can get it to hang around through March!

 I'm not aware of a comprehensive writeup on neutral ENSO. It will largely be dependent on the PDO/NAO-AO combo. As far as I can best tell, neutrals are generally all over the map although neutral positive may have a slight cold edge over neutral negative. There were two quite cold neutral positive ENSO winters for sure: 1884-5 and 1935-6.

 

For 1935-6, PDO was +1.5, NAO was -2.0, and AO was -2.4.

 

 20 of the 26 +PDO/-NAO/-AO winters were NOT weak Nino’s. Only 4 of those 20 that were +PDO/-NAO/-AO and that weren’t weak Nino’s (20%) were within the 11 coldest. So, whereas it helps a lot to have the +PDO/-NAO/-AO combo, regardless of ENSO, the combo has done by far the best with weak El Nino.

 

 I put the odds of a weak Nino by this winter (per ONI definition) to be well under 5%. Basically, it is too late barring some extremely anomalous, sudden rise in 3.4. The better chances would be for a weak Nina although neutral would easily be favored.

 

 It appears that any El Nino, if there is going to be one anytime soon, would need to wait til spring at the earliest to be fully in effect.

 

Larry, these are monthly snowfall accumulation maps from 1935/1936 that I posted some time ago at Easternuswx.  Nearly thirty inches of snow fell that winter southeast of Charlotte.
