The Allsnow Blizzard of 2026

[495weatherguy]

Can we get estimates on timing?  
 

For example, starting time.  
 

The time it starts to crank

Duration

blizzard conditions timing 

End time?

 

not looking for exact times   Just best guesses

 

[weathermedic]

Winds will be insane according to HRRR

Still snowing btw.

At the end of this run still precip all the way back into almost central PA so at least another 6-7 hrs with the low crawling.

Looks like light snow into the city around  noon maybe a bit earlier.  Snow in some capacity at least until Monday afternoon.

I think it was the January 31, 2021 event. That one went at least 3 days, maybe even into a 4th.

Thank you!  
 

really trying to figure out if it’s worth staying up all night or not. 
Even though my days of loving snow are in the past, this seems like a potentially special, once in a generation type storm. 
worth losing a little sleep over it

Really do not envy forecasters in the DC area. Models showing anything from 2 inches to over a foot; gonna be a real nowcast situation down there

Blizzard and Winter Storm Warnings Expanded

The blizzard warnings were extended about a county inland by the NWS (counties in orange) and those watches for counties in NEPA were converted to warnings (pink), as the NWS clearly has more confidence in more snowfall making it that far inland so they upped snowfall for everyone especially west of 95. Below is a bulleted summary of the blizzard/winter storm warnings which is easier to digest than those long text strings the NWS puts out. Hopefully we'll see a new NWS map soon, as snowfall amounts have been increased, as per these warning amounts. Specifically, the warning for Somerset/Middlesex/Mercer is for 16-20" of snow and the map had us at 12-16" (and this goes for everyone). The links below have the full text for all of the warnings.

Blizzard Warnings from the NWS-Philly and NYC
 

• Blizzard Warning for Atlantic-Cape May Counties for blizzard conditions with total snow accumulations between 12 and 20 inches and winds gusting as high as 50 mph.
• Blizzard Warning for Gloucester-Camden-NW Burlington-Cumberland-Counties for blizzard conditions with total snow accumulations between 14 and 20 inches and winds gusting as high as 45 mph.
• Blizzard Warning for Monmouth-Ocean-SE Burlington Counties for blizzard conditions with total snow accumulations between 15 and 20 inches and winds gusting as high as 50 mph.
• Blizzard Warning for Morris-Somerset-Middlesex-Mercer Counties for blizzard conditions with total snow accumulations between 16 and 20 inches and winds gusting as high as 45 mph.

Winds were pretty middling with that one, this will have insane drifting.  Looks like gusts 55-60 well inland could be 70-80 on the immediate coast.

all of NJ is crushed-lots of snow back into EPA now too

[Snowlover11]

My goodness the nam is insane and it justs getting going here. Jersey is buried.

[weathermedic]

Remember the NAM tends to overamp so maybe cut it down by 1/3
