RUC looks mighty fine, messenger. Mighty fine.

The last few times it hasn't mattered much but:

GFS had a much better handle along the TX border it would appear vs the 6h NAM. At the same time the NAM was probably better with the critical s/w coming into the upper OH valley.

Be interesting to see what a slightly faster timing out of TX does with a similar timing up north.

Indeed. I was reading the Mt. Washington wiki page and found this:

For many years, the record low temperature was thought to be −47 °F (−44 °C) occurring on January 29, 1934, but upon the first in-depth examination of the data from the 19th century at NOAA's National Climatic Data Center in Asheville, North Carolina, a new record low was discovered. Mount Washington's official record low of −50 °F (−46 °C) was recorded on January 22, 1885. However, there is also hand-written evidence to suggest that an unofficial low of −59 °F (−51 °C) occurred on January 5, 1871.

That's news to me. Anyone else hear anything about that?

I also realized I'm not in the right thread... oops. :yikes:

Wow, very cool.

NAM:

Strange, the 12z NAM gave me this which makes MUCH more sense given the QPF maps. Clown map looks wrong.

I haven't really been paying attention to start time. Wee hours? I think the commute will drag but dunno about flights.

My co-workers told me that the tv stations and NWS are all from 2-6". I said I knew that, but latest guidance says wagons north. Point is, if it happens it'll catch people quite off guard here. Nice change of events from 24 hours ago.

I would guess start time around 3AM in PWM area.

I too have been met with incredulous looks when I spread the news of 6+ inches

For those still wondering about Euro QPF: SNE jackpot is NW GC through all of S VT, S NH, SW ME, and then down into Essex Cty. and KGAY with .5''+.

i wouldn't include any of VT or Maine in SNE geographically. extreme S nh salem....nashua....etc ....over to hampton beach area.

but that is some what of news to me....( i thought down east maine ...yes) but not S VT or NW ma?
