Weather Update from Monsoon for Wednesday, 12 December 2007
Weather update from Monsoon for Wednesday, 12 December 2007…
Weds 12/12 cloudy and quite foggy with morning showers and a slight chance of afternoon showers. Temps beginning near or just above 50 after rising overnight, then falling through the 40s in afternoon and evening, finally arriving at a low around 30. Moderate to strong winds becoming light.
Thu 12/13 colder with scattered freezing rain and sleet in the morning, beginning perhaps by mid to late morning; a bit of snow may even mix in from Reading northward. A messy mixture will persist throughout the day with mostly frozen precipitation before noon, then rain with a bit of frozen mixed in for the afternoon, then from 5pm onward frozen precipitation (mostly snow) predominates again. Precipitation (in whatever form) will become steadier and heavier throughout the afternoon and evening, tapering late.
Chance of delay: 10%. Chance of cancellation: 15%. Chance of early dismissal: 55%. High 33, low 29.
Accumulations depend greatly on storm track and temperature fluctuations, which are up in the air right now (no pun intended). My best guess right now is that areas in Reading northward will have 4 inches of accumulated snow by late Thursday night, with some sleet and freezing rain mixed in to make things messy. South of Reading and into Lancaster may have a bit more of the freezing rain and sleet, less of the snow.
Fri 12/14 clearing considerably and somewhat milder. High 41, low 22.
Chance of cancellation: 20%. Chance of delay: 60%.
Sat 12/15 there’s the potential for a “doozy” of a Nor’easter on Saturday into Sunday. Right now so much could change—storm track, air temperature, water temperature, and other factors could throw a mighty monkey wrench into this thing, pulling it off-course or making it all or mostly rain for our area. Right now, though, it looks as though rain begins early Saturday afternoon, changing to snow by evening and continuing, heavy at times, through Sunday afternoon. It should be quite windy, too, so snow-sagged power lines and falling limbs could be an issue. Forecast models (and some of my own digging) suggest this could be a significant Nor’easter with snow totals reaching double digits. Again, there’s no reason to get your draws in a tangle over this yet, but it’s something I’m watching with more than a little interest. High 33, low 22.
Sun 12/16 as stated above, snow could persist into Sunday afternoon, giving way to a mostly cloudy night of shoveling. High 37, low 23.
Mon 12/17 these numbers will, of course, be updated on Friday as things fall into clearer focus. Partly cloudy, windy and very cold. High 31, low 18.
Chance of cancellation: 60% (if the storm hits); chance of delay: 75%.
Tue 12/18 sunny and very cold. High 28, low 14.
Wed 12/19 cloudy with snow developing late. High 29, low 21.
Thu 12/20 cloudy with periods of snow and sleet giving way to rain in the afternoon. This is another one to watch; could be hazardous. High 38, low 24.
Fri 12/21 partly cloudy and milder. High 41, low 29.
Next weekend cool Saturday with a chance of rain, freezing on surfaces at times. High 35, low 26. Sunday will clear up; sunny conditions will prevail. High 37, low 29.
Beyond temperatures adjust to about normal for this time of year—highs in the upper 30s and low 40s; lows in the upper 20s to low 30s. Right now it’s not looking like it’s going to be “White Christmas” (unless we get this storm on the 15th and another potential storm on the 20th, and the snow ground cover from these lingers).
