A cold front passed through the city yesterday afternoon bringing much cooler and drier air to the region. This afternoon's high will be in the lower to mid 40s, which is still several degrees warmer than average for late January. It won't feel nearly that warm thanks to the storm we had earlier in the week. As expected, that storm has gotten stuck under a trough of low pressure and is going to spend the next few days meandering around the Canadian Maritimes. What that means for us is a weekend of brisk winds and a wind chill making it feel more like the mid 20s to mid 30s.
The temperature is likely to stay above normal tomorrow as Saturday's high will again reach the lower to mid 40s. As cold air continues to arrive from northern Canada, Sunday will only reach the lower 40s and Monday will probably be the first colder-than-normal day in more than two weeks, with a high only in the mid 30s.
The cold air looks like it is going to stick around for the foreseeable future. The jet stream is setting up in a classic pattern where it ridges up over the western half of the country and dips into a trough over the eastern half. If that happens we are looking at a couple of weeks with highs in the 30s and lows in the 20s.
