Nice improvement on the GGEM.

Comparison of the 1/19 6z and 12z GFS runs: 6z: 12z:

Yes. You're right. Hopefully, the moderators can move my misplaced posts to the correct thread.

I made it from the 24-hour Pivotal weather QPF amounts.

Places like Westhampton will likely see at least single digits, assuming clear skies and a lack of wind. Records for Westhampton are -7 on 1/24 and 1 on 1/25.

Only a few locations could tie or break record low maximum temperatures. Record low minimum temperatures are too low.

Unfortunately, that's the whole list from 1950-present.

For historical reference, the biggest snowstorms/blizzards during January-February 1950-2025 during an AO of -3 or below and PNA>0 were: January 29-31, 1966: Washington, DC to Boston all saw 6" or more, but the heaviest amounts were in Washington, DC and Baltimore February 5-7, 1978: Baltimore to Boston saw 6" or more, but the heaviest snows extended from Philadelphia to Boston. February 4-7, 2010: A blockbuster storm in Washington, DC to Philadelphia. No measurable snow in New York City or Boston. February 9-11, 2010: Washington, DC to New York City all saw 6" or more (10" or more) with the heaviest snows falling in Baltimore and Philadelphia.

A westerly wind burst appears to be developing. However, at present, it has not yet translated to the surface, as the SOI has remained at or above +20 for four consecutive days. The most recent ENSO Region 3.4 anomaly was -0.7°C during the week centered around January 14th. That's almost identical to its six-week moving average of -0.68°C. So, at least through the most recent week, the La Niña has been remarkably stable. The La Niña should gradually weaken, not collapse. Weekly ENSO Region 3.4 values could rise to neutral-cool levels late this month or during February. However, the fade appears likely to be gradual. As a result, La Niña will likely continue to exert an influence on the atmosphere through at least the first week of February. The AAM- is consistent with a La Niña-type pattern. The WPO-/EPO-/AO-/PNA+ pattern will likely be the biggest driver of North American weather conditions through the remainder of January. That pattern is typically the coldest January pattern for the eastern half or third of the U.S., along with at least southern Ontario and Quebec. One or more lows in the single digits and one or more highs in the teens is possible in New York City. Subzero cold is likely in places like Chicago, Detroit, and Toronto. The predominantly positive PNA comes with a heightened risk, relative to climatology, of moderate or significant snowstorms for the East Coast. With the PNA likely to be mainly positive into or through at least the first week of February, it is likely that at least one or more of the following cities will see at least one 6" or above snowstorm from the remainder of January through the first week of February: Baltimore, Boston, New York, Philadelphia, Richmond, and Washington, DC. Warmer than normal conditions will generally prevail in the Southwest.

The RGEM had the best QPF forecast for the January 18th event while the ECMWF was a close second. The EC-AI had 0.39".

The 0.9" was the storm total through 7 pm. Some additional snow has fallen since then, so the final figure might wind up around 1.5"-2.0".

Through 7 pm, Central Park had recorded 0.9" of snow.

This evening. A steady light-to-moderate snow:

I believe the issue is that locations don't show up when one is posting and reading on the phone. I only see them on the desktop.
