Looking at the medium and long range GFS models– A relatively mild stretch of weather is shaping up for the first half of December. Mild, cloudy and wet seems to capture it.
Maybe my sense of a milder winter may come true despite the cold period we just experienced.
A weak warm frontal pattern will develop today as high pressure moves slowly off to the east and the upper air trough responsible for the unseasonably cold weather finally de-amplifies.
With the return of somewhat milder air aloft, there is an expected development of mid-level clouds– altocumulus and altrostratus – that will give a continued grey, November feel to Saturday.
So Saturday will be mostly cloudy, some breaks of sun possible, a bit milder but still unseasonably cold with a high temp near 40.
Winds shift to the southwest tonight and milder temperatures are expected on Sunday with highs in the low 50s. There may be some low level clouds at times, but much more sun than Saturday.
The storm today, which had always looked primarily like a rain maker here in Philly, appears to be even warmer than expected. Heavy rain most of the day….changeover to snow in the immediate PHL area late afternoon or after dark now. About 1 wet inch accumulation most likely.
Don’t let those TV weathercasters fool you. There weren’t any last minute changes they “tracked”. This wasn’t ever going to be a “snow shhtorm” They’ve been hyping the snow potential of this storm since Sunday, even when all indications were that it would be a mostly rain storm all along right in PHL.
