Oops, I hadn't read Clark's post above . So Noel was warm core.

I checked the latest meteogram at CWWE- Western Head, N.S., Canada. It covers the period from 12Z on Saturday to 17Z on Sunday-today.
Two meteorological parameters are slightly obvious.
Temperature at 12Z-Saturday was 9C, dewpoint 5C, wind NE at 22kt gusts to 30kt. Pressure 1026.7mb
Temperature at 03Z-Sunday (last night) was 16C, dewpoint of 15C (nearly 100% rel. humidity), wind SE at 30kt gusts to 40kt. Pressure 985.5mb

See attachment.

So you warmed by wind flow, increase in temperature and humidity. Not to mention the pressure dropped from 1026mb to 985mb in 15 hours. Roughly a 3mb drop per hour. Nearly a typical drop for an approaching Cyclone. I've seen 6 mb per hour drops at coastal stations bordering the GOM.
