Noticed temps around State College tonight varied 10+F in short distances. Classic case of when the boundary layer "decouples". Calm wind very close to surface with a breeze just (can be as little as 20-30 feet) off the ground/at higher elevations. Took a walk to explore. One of the most impressive examples I've seen of this scenario. Used my Kestrel to measure temps on a short walk that varied from about 1,160 to 1,240' (80' total). Roughly plotted the obs to show the 16 (!!) degree difference!

With the #polarvortex last week and the potential for significant Pac NW snow, I thought it'd be interesting to look at the "benchmark" arctic outbreak on record. Behold, the Great Arctic Outbreak of Feb 4-14, 1899. /1 The majority of what follows is taken from Kocin, Weiss, Wager (1988). Highly recommend the read along with the Weather Bureau Monthly Weather Summary /2
