Here is the Kuch map from Pivotal for the same period of the Nam. Pivotal maps do a better job at separating different frozen types like @Voyager mentioned.
I have really grown to dislike those TT maps. LOL. You have to spend time investigating taint and such. But every map I saw was a good 7-10" or higher so even without clown totals just the law of averages would suggest someone could over perform more than 10% of the time.
Blue Ridge was very icy last night but it never went below freezing here so the only ice I had was trash can topper/yard sign topper type. Its 35 right now. If you are familiar with Harbaugh Church Road I am located on the road that goes up to Pen Mar albeit it near the bottom of the incline.
Right now we are at 34 and plain rain and just a couple miles away/600 feet up its 29 heavy glazing on Blue Ridge Summit Right. That area is a living jackpot.
I am going to have to Deb and throw out this DP map and really question major Ice in Southern PA. Most people are nearly saturated and most DP's are in the 30's now. This is a DP map, FYI. Not air temp.
Yea, being a little farther west helped me score earlier. Cad in particular is terrible here and when SLP's come up from the S/W I cave to taint pretty quickly. You are also quite a bit father north than I am.
I am being haunted by being on the other side of South Mountain. My valley is not a good one for weak CAD. We are down to less than 1/4 mile visibility. Snow pack killer today.
