Looks like the lead shortwave shoots out too quick, misses the better phasing we saw earlier

Woof woof We obviously want to see more continuity through tomorrow, but no question this is the best signal (cross-guidance and ensemble support + in shortest lead time) we've seen all winter

Agree with both, just was amused by the very precise shirk inside 128. Honestly haven't invested much time / care in this one, a pretty low ceiling for SNE. Not true for next week...

Circle shirk?

Woof for 2/28... nice cross guidance signal

This was days after the 28-3 Superbowl... Similar to 2015, sometimes feels like concordant feast or famine in these parts Thundersnow ~2:30-3:30pm in eastern MA

-10˚F !!!

HRRR suggests we have a few more ticks, bottom around 2-4am 12:40am Wundermap:

-9 Gusts picking up again

KBOS -7 at 11:45pm I believe that’s a new record low for Feb 3

-7˚F !

Pour out some water onto an incline or pole... pretty cool, it's a rare night

-5F at 10pm This is really impressive Went for a walk... can't really be outside barehanded for more than a minute I poured water down a driveway apron out of curiosity... the streams froze at ~1 foot length before they reached the bottom of the apron

That ORH ASOS is such a debacle on a potential record night. As expected from 925mb, some of the most intense gusts and fastest plummet in past 2 hours. Should abate a bit after 10pm 4F 6:50 2F 7:27pm 1F 7:40pm 0F 7:55pm -1F 8:20pm -2F 8:33pm MBY probably plateaus somewhere -10-12 In case wasn't posted earlier: Record Low Temps Fri Feb 3...

KMWN 1849Z 290 78G92KT –37/–37 ..."Winds will continue to increase through the rest of the day, with winds speeds reaching 80-100 mph by Friday afternoon. Model guidance is also indicating that the tropopause could dip below the summit Friday night. As a result, winds will become more compressed in the lowest levels of the atmosphere, leading wind speeds to increase even further overnight Friday. The highest wind speeds will occur sometime between Friday night into Saturday morning as wind speeds ramp up to 100-115 mph with gusts up to 135 mph. Higher gusts are not completely out of the question, with the possibility for winds to peak as high as 140 mph very early Saturday morning. Wind chills will be incredibly low and very dangerous, particularly above treeline. Wind chill values will start around 60 below to 70 below Friday morning and will continue to fall even further over the rest of the day. The coldest air from the center of the polar vortex will move through the region Friday night which will also coincide with the period of strongest winds. As a result, wind chill values will drop to a range of 100 to 110 degrees below zero Friday night. I want to emphasize the danger of this cold. In these brutally cold conditions, the risk of hypothermia and frostbite will be exponential. These frigid cold conditions will quickly rob you of body heat, with the possibility that frostbite could develop on exposed skin in under a minute. Even small mistakes can prove deadly, with a simple slip or fogged goggles leading to a potentially life-threatening situation. In this type of weather, rescue services will have a difficult time responding to any emergency effectively." https://www.mountwashington.org/experience-the-weather/mount-washington-weather.aspx

Opening bid from Box… looks like a 70:30 GFS:NAM blend Almost a redux of today’s totals, with more of a latitude component and no CCB jack east
