Yeah I have many times on many trails and in all seasons including winter. I've had some high speed easy hikes on Mt Washington & the Presidentials and I've also had days of getting hit in the face with a 100+mph wind at minus ten
If you're planning on doing this mountain before May it can be a really nasty and dangerous hike up and down
If you plan to hike it now[and I don't recommend it } be prepared for a no bs winter climb ; Ice axe ,crampons ,-30 bag liquid fuel stoves ,7000 calorie a day diets ,snow googles, the whole shebang
This is neither the time nor the place to be practicing "Go light Go Right"
Once you leave the relative safety of timberline you absolutley must be prepared to spend a night on the mountain. When the weather turns to crap and you're hiking in zero viz w/100mph winds , seeking immediate shelter is the name of the game and having the gear with you allows you to survive the game to tell the tale
Here's the current weather on summit
What I find interesting is the low wind speed and the complete lack of gusts.Trust me neither situation will stay that way for long

Summit Forecast – Monday, January 12, 2009
Cloudy skies and light but increasing winds will remain the story today as an upper-level disturbance quickly passes over the region and an area of surface high pressure passes to the south. Very light winds will continue early today, but should begin to gradually increase during the afternoon. A weak area of high pressure will quickly pass to the south of the region, allowing winds to shift towards the northwest. As the high moves offshore tonight, winds will shift back towards the west, and skies may clear for a while. In the meantime, an area of low pressure will begin to develop over the Midwest and move towards New England, but pass to our west. A second, developing low will develop off the Carolina coast and move northward along the eastern seaboard, passing to our east almost simultaneously. The duo of lows will yield a few effects atop the summits tomorrow. Firstly, winds will shift to a southwesterly direction out ahead of these storms, drawing up warmer and moister air, allowing overhead clouds to return. Also, the interaction between these lows and the exiting high will cause these winds to increase in speed during the day tomorrow. And finally, as the storms draws nearer later tomorrow, light snow may begin to develop atop the summits. A strong northwest flow will begin to set up tomorrow night in the wake of these storms as an upper-level trough entrenches itself in the northeastern United States. This will open the door for some of the chilliest temperatures of the season as bitter Canadian air pours in.
