Lol, this worthless storm is infuriating me to the bitter end… I I don’t think that I have EVER seen a freaking change over happen well to my South east prior to my change over to snow in Marysville. Normally the change over happens first in Altoona, State College, Newport, Marysville, MDT, then Lancaster l, etc… Not tonight!

Snow/rain mix. 35F nice size flakes…

Flurries in babylon

CPC isn't perfect too.. this pattern last Winter was called +PNA. This would have been "positive" on your graph. 2025 1 15 0.8425661297669382 2025 1 16 0.6292797257596462 2025 1 17 0.3591812956820121 2025 1 18 0.2963853705652808 2025 1 19 0.25645632216650666 2025 1 20 0.19665558838216474 2025 1 21 0.16494891370677975 2025 1 22 0.3096868402976654 2025 1 23 0.16090618641248808 2025 1 24 0.090735 2025 1 25 -0.00812 2025 1 26 -0.00391 2025 1 27 0.12996443644301287 2025 1 28 0.058971 2025 1 29 0.075685 2025 1 30 0.22591144673920 158 2025 1 31 0.28769816664388287 2025 2 1 0.23227473560905743 2025 2 2 0.061725 2025 2 3 -0.15733 2025 2 4 -0.14046 2025 2 5 0.22531992513175264

I hope its a super nino. Texas is parched. We need about 50 inches of rain and a Harvey over Austin for 5 weeks.

Roads slowly whitening in Exton. 33 degrees. Got to admit I laughed pretty hard when I saw a thread for this last night. Thought it would be all rain, or white rain not amounting to much.

Big flakes here but melting on contact with everything except cars and existing snow piles

Was just out walking. Snowing steadily but not sticking

Are you using the DM or CPC indexes? The CPC balances and evens it all out, so negative is just as probable as positive. Side note, but they are really moving toward RONI for ENSO monitoring: Climate Prediction Center - CPC adopts Relative Oceanic Niño Index (RONI) for reliable, responsive monitoring and tracking of ENSO

Snowing here

You are not alone. lol Over the years, I've noticed many quirky sticking patterns too. One is sticking in the expansion joints of sidewalks, but not on the sidewalk surface itself. Freezing rain glazes over cars more than on wood surfaces. Of course, sticking on grass before anything else. Sticking on rough pavement surfaces before smooth pavement.

95-96 was 66 96-97 was 21.5

I guess I’m just having trouble understanding how you’re getting that strong of sfc lapse rates and differential heating aloft on the mountain side snow surface. Do you get whirls like that during warm season?

In 18,000 BC this would've been 10" of snow on 20:1 ratios.

7 car accident out here on 222 s Spring Twp roads are caving moderate snow

They seem to start during differential heating or steep lapse rates during CAA. We seem to get them during times of broken clouds/partly sunny conditions after a snow, with a strong 850 mb flow amid steep low level lapse rates.

Rain about to end here. Almost .5". This was a better event than I thought it'd be. Much needed and I won't miss the salt that covered everything.

I'm amazed that there's still some semblance of a snowpack outside my window after the conditions this weekend

Moderate snow ivyland....expectations exceeded. 33F

Fascinating observation (to me at least): the snow started to accumulate on the 32F sleet/snow on the ground maybe 5 minutes ago, but isn't accumulating on our deck table (stone, so probably at least in the mid-30s), but did just start accumulating on our rattan deck chairs (likely colder than the table). Pretty sure it'll be accumulating on everything soon as intensity is picking up.

I can do that someday, not going to do that tonight lol. But the issue is ridges are becoming more significantly anomalous. So you won't see as many crazy anomalies in the past because they didn't exist as much. We are seeing more and more positive anomalies now...which yea makes it harder to overcome a hostile pacific...which is why we aren't snowing as much!

Starting to snow lightly here, wind picking up out of the east.

i had Central Park hitting 42 today for a high anyone know the split?

Can you do it with >1std to the index pattern? I know sometimes a good gulf of alaska low pressure pattern will be called +EPO.

Did not know TS occurred w/ the May 1977 event. I wish these obs were also archived in the original SA format. Also, all remarks were lost for some reason when they converted the SAs to METAR format. Those were the best part! LTG obs and SNOINCRs, among other things.
