January 23rd, 2008 Forecast

The super sprinkle event of late January is on its way out of here and we're going to see things settle down weatherwise for at least a day or two. Cooler air will work its way in here on Thursday with a reinforcing frontal boundary that will move through but we should have one somewhat decent day tomorrow around here.

Tonight: Clouds should diminish around midnight and temperatures will bottom out in the mid and upper 20's across the area. Any rain, sleet, and snow showers that are still falling this evening should wrap up relatively quickly. Dry air aloft limited the impact of the precipitation in our area and many of us have only seen a short burst of precipitation during the early afternoon.
Wednesday: Sunshine with some afternoon clouds will lead to a pretty decent day around here. Temperatures should end up just shy of 40 in Philadelphia and winds from the west will be around 10 mph. Temperatures around here will be pretty normal for this time of the year. Coincidentally, tomorrow is the last of the "coldest days of the year" stretch we see every year from January 18th to the 23rd, with an average high of 38 degrees each of those days. Here on out, the temperature will be on its way up through the latter portions of July.
Thursday will feature a clipper that will usher in another chance of snow showers as it transfers its energy to a coastal low in the Western Atlantic. Computer model guidance is waffling about what will specifically happen snow-wise but it's possible we could see more than a few flurries around here and could get into light snow.

Another chance of rain is expected on Sunday night and early Monday with a storm coming up from the south. It should be rain around here as temperatures will likely rebound for the end of month and the track of the low looks to be close enough to Philly to keep us mild enough to avoid snow.

Another place with snow: A stubborn upper level low has lurched off of the San Francisco region in recent days and the mountains in the San Jose area saw up to eight inches of snow yesterday from the slow moving low pressure system.
