The Mount Washington Observatory shared the Facebook post below this morning. Temps dipped down to -30F, and felt like -80F with wind chill. Cold enough that it froze a plate of spaghetti!

It’s kind of a goofy way to gauge temperature, but have you ever been in temps where your food could freeze solid and support a fork?

Yeah… I didn’t think so! 😂

Mount Washington Observatory Meteorologist Ryan Knapp is forecasting brutally cold temps today, tonight, and tomorrow. Temps will feel like -70F to -80F with wind chill today.

Here’s his full forecast from Mount Washington Observatory:


High pressure will build over the region Tuesday then crest and slide offshore overnight as a trough approaches from the west for Wednesday. Tuesday will start very cold and windy as arctic air flows down ahead of the building ridge. As the cold air flows down this morning, it is likely that the daily record low in our dataset for the 11th will be tied or broken. A drying pattern is expected with the building ridge providing clearing skies and a good amount of sunshine. Despite the added sunshine though, temperatures will struggle to rise much over the course of the day. Winds will gradually decrease as the ridge builds but they will remain strong enough to make the cold air feel significantly colder on exposed skin. The cold air and high winds will also reduce exposure times with frostbite risks possible in less than 5 minutes and heightened risks for hypothermia. As a result, a wind chill warning will remain in place on the summits today and remain until Wednesday morning at 8 am EST. The cold and windy conditions will extend down to neighboring trailheads where a wind chill warning will remain in place until noon EST Tuesday. Overnight, the ridge crests and starts to slide offshore. This will result in winds increasing once again as a slight return flow starts to set up. This will allow temperatures to continue to slowly rise overnight. Despite temperatures improving overnight, as winds also increase, it will continue to feel nearly unchanged on bare skin through the night and as stated earlier, exposure risks could develop in minutes. Clouds will start to spread back in Tuesday night as a trough approaches from the west. Clouds will thicken and lower on Wednesday with summit fog developing during the afternoon hours, which will continue overnight. A few light snow showers will spread in during the afternoon and then linger overnight as the trough starts to move through. Winds will crest on Wednesday morning then decrease through the afternoon and overnight. As milder air from the southwest rotates into the region, temperatures will continue to rise Wednesday and through Wednesday night on the summits.
