High temperature records were set across the city and much of the Northeast and Midwest yesterday as a warm air mass managed to push its way far more northward than is usual for January. Central Park hit 66 degrees, breaking a record that was set when Benjamin Harrison was president and it was 70 degrees just a few miles south of the city near the Jersey shore.

As if to remind us that it is still winter, a strong cold front passed through the city early this morning. Behind that front is a gigantic polar air mass that is currently centered over Minnesota. The weak mid-January sun can't compete with the arriving cold air, so look for the temperature to hold steady in the mid 40s through early this afternoon before plunging down to the mid 20s by tomorrow morning.

The coldest air within this high pressure system will arrive tomorrow. Combine that with cloudy skies from a weak disturbance passing overhead and you get Saturday's high sticking to the upper 20s or lower 30s. We might see a few snow flurries in the afternoon but no accumulation is expected.

Look for the temperature to return to near normal on Sunday and Monday as the axis of the cold air mass moves eastward. Sunday and MLK day should both see highs in the low 40s, which is just a couple of degrees warmer than normal. A long stretch of even warmer weather is expected to begin by midweek as the jet stream takes on a flatter, more west-to-east circulation pattern. No daily records are expected but we could see highs that are 5-10 degrees warmer than normal each day for the rest of the month.
