Just like that the models are decreasing rain totals again for this week

That’s depending on where you are of course. It looks like the heaviest has shifted southward into the Deep South leading to an increase there, where they also desperately need rain.

 Looking way on down the road toward next fall/winter, the highly likely El Niño is encouraging for rainfall prospects for much of the SE then.

Wow

 I’m even more speechless than yesterday! For Mar 7th, the mean has plunged from +20 with only 2% reversing around then a mere 5 runs ago to -11 and 100% reversing on today’s!! Again, I’ve never seen anything anywhere close to this much run to run drop before. 
 
 Despite this, the EW run for the 3 weeks near and after Mar 7th is even milder than yesterday!

More on the PNA that was -1.2 for this blizzard:
 

20 NYC 5”+ snows for Feb -ENSO since 1950: PNA

2/1/57 -1.2

2/7/67 +0.7

2/19/72 -0.5

2/23-4/72 -0.5

2/8/74 -0.2

2/12/75 -0.8

2/7/79 -1.1

2/19/79 -0.1

2/5-6/85 -0.8

2/2-3/96 +0.7

2/16/96 -0.4

2/22/01 +0.4

2/12/06 +1.7

2/22/08 +0.7

2/8-9/13 +0.4

2/3/14 -1.1

2/13-14/14 -1.0

2/9/17 +0.7

2/1/21 0.0

2/22-23/26 -1.2

——————

Median -0.2

Mean -0.2

 -So, this latest one tied with 2/1/1957 for the lowest PNA for a Feb -ENSO NYC 5”+ snowstorm since 1950.

-Note that DC, which hasn’t done as well as NYC with a -PNA for a similar category of storms, didn’t reach the 3”+ criteria that I use for them.

2/22-3 NE Blizzard: indices

1. PNA -1.2

2. AO +0.2 (neutral)

3. NAO +1.1

4-5. EPO/WPO: strongly negative (waiting on verification)

6. MJO inside circle both days

2/22: phase 3 

2/23: either phase 3 or phase 2 (near border and thus waiting on verification)

7. AAM: -0.9 (moderate La Niñaish)

8. SOI: +6

9. PDO: negative

10. QBO (30 mb): strongly negative

KSAV (official SAV station at the more inland airport) had a solidly cold 28 low (16 BN) and a 5 hour long freeze, not too common this late in the winter. The daily record low is 25. That’s quite the impressive turnaround compared to the record high (86) and high low (65) set just 3 days ago!
 
 KSVN had a low of 27.

 Today’s high will be a bit warmer but still only ~mid 50s, which is well below the normal of 67. This will be another great day for a walk.

Horrible Spring ?

If by “horrible” you mean cool spring in the E US, good! Bring it on as I love it way down here! Actually cool late Mar/early April here means highs mainly 60-75 and lows 40-50 along with nice low dewpoints for great outdoor wx.

..RECORD DAILY LOW MAXIMUM TEMPERATURE SET AT ASHEVILLE  
 

  THE HIGH TEMPERATURE WAS ONLY 28 DEGREES MONDAY, FEBRUARY 23 AT THE   ASHEVILLE REGIONAL AIRPORT. THIS BREAKS THE OLD RECORD LOW MAXIMUM OF   29 DEGREES, SET IN 1989. RECORDS FOR THE ASHEVILLE AREA GO BACK TO 1869.

@40/70 Benchmark are we getting a reversal?

This is the most rapid run to run 10 mb mean wind drop to a reversal I’ve ever seen! Just 4 days ago on the 2/19 run, March 7 had mean winds way up near climo of +20 m/s and only 2 of 100 members reversing around that date:

On today’s, which you posted, it has March 7th way down to -2 m/s and ~75% of members reversing!! Unfortunately though, today’s weeklies continue to not show any significant long lasting widespread cold in mid to late March. Hoping that changes/keep hope alive!

~1.65” of liquid equivalent has fallen at NYC/C Park as of 11AM and it was still coming down! This storm is nearly beyond description.

This is snow deserving gold medal status at NYC as it is their biggest snow in a decade. More snow has fallen there since yesterday than even some of the Olympic ski areas this entire month!

.38 liquid on Central Park from 7-11 am and the 7 am measurement for snow was 15.1 inches.

They have to be at 19-20 inches now minimum.

Thanks. With that, now up to ~1.65” liquid equivalent at CPark through 11AM!

This is deserving gold medal status with more snow since yesterday than even some of Olympic ski areas this entire month!

1.56” of liquid equivalent (all in the form of snow except perhaps the first .01-.02”) has fallen at NYC/C Park as of 10AM and it’s still coming down very heavily! This storm is nearly beyond description.

@jconsor the above states phae 7 is cold for March. Not sure the diff.

 Thanks. Keep in mind that although it has been the coldest at Baltimore during La Niña in March, that’s only the avg as there’s lots of variation:

“Breakdown of the 18 different Mar La Nina phase 7 periods: wide range but more B/MB (8) than A/MA (6)

MB: 2
B: 6
N: 4
A: 3
MA: 3”

 Thus, whereas averages are informative, they don’t tell us how any one case will actually turn out. That’s the case for any phase. Those H5 composites are just averages.

 Also, phase 8 has been the 2nd coldest during Mar for La Niña averaging only 1F less cold than phase 7.

 Aside: current storm looks like it happened during phase 3, the coldest on avg (prior to 2026) by a wide margin of any phase at Baltimore during La Niña in Feb.

There was a midnight report from central park of 8.8. Is this correcting the midnight measurement or just giving a 1am update ?

That 9.3” at NYC appears to be as of 1AM just like the 7.8” at JFK.

Chilly spring?

Hey Anthony,

 Congrats on your blizzard!

 I’d love it and JB has been going cold til after Easter after a warmup Mar 5-15. But unfortunately the Euro Weeklies are overall not cold looking for most after the upcoming week. Then again, look how much colder the upcoming week will be vs what the Weeklies had just 6 days ago for 2/23-3/1:

Now look at it today (similar to last few days):

and week 2 (3/2-8) has cooled a good bit especially in the NE:

From 6 days ago:

Compare that to today:

 So, based on the big changes for weeks 1-2 in the East, keep hope alive!

Wow, this sort of came out of nowhere!

Just 3 days ago EWs had a near climo normal mean of +20 m/s and only 2% reversing on/near March 7th:

Today they have a mean of a mere +4 m/s for Mar 7th and probably ~25% reversing near then:

@40/70 Benchmark

3PM hourly for KSAV: wind gusted to 52 mph! This has caused some outages in the SAV metro (>3K).

CITY SKY/WX TMP DP RH WIND PRES REMARKS  
SAVANNAH MOSUNNY 58 13 17 W32G52

The wind here is putting on enough of a show for a wind advisory as the refreshing Canadian air continues to rush in with virtually cloudless skies. Winds have already gusted to as high as 44 mph at the airport! I’ve been needing to clear my roof of leaves/debris. Well, Mother Nature has done me a favor and already cleared a good portion of it today with the yard now a mess! It was ~64 at sunrise and it’s now 60.6. Looking forward to walking!

 Expecting a slow fall the rest of the afternoon as we head for low 30s by morning. Cold wx advisory is out. Tomorrow’s high is forecasted to be only in the upper 40s, which compares to yesterday’s 86. There’s a near 100% chance of a freeze tomorrow night. Expecting freeze watches soon. N FL already has them for tomorrow night.

Edit:

 I forgot to post my rainfall from last night through just after sunrise. I got 0.65”. That added to my 0.75” of Feb 15th gives me a beneficial 1.4” for the 7 day period  ending this morning.

Ehh, 41.5 now.  Gonna get hard to freezing. 

The model consensus has been suggesting you may bottom out just above 32 but still with snow accumulating, especially on nonpaved surfaces, starting ~4-6PM.
