The temperature has dropped an impressive forty degrees since the Wednesday afternoon high of 70. After a morning low of 30, the mercury will climb to the upper 30s later today. A gusty westerly wind will make it feel much colder than that.
A second cold front will arrive this afternoon, reinforcing the cold and possibly giving us a brief but intense snow shower. The National Weather Service is still clinging to the idea that the city will get a quick dose of snow in the early evening, but it is looking more and more like the snow will mostly stay north of the city. It is also looking more and more like Saturday will be the coldest day since early January with a high barely reaching 30 and wind chills near ten degrees for much of the day.
The cold air will bottom out on Sunday morning after a third cold front allows for more Arctic air to push south. Sunday morning's low will be in the teens in the city and near zero in more rural areas. The big high pressure system bringing the cold weather will slowly move eastward, allowing the temperature to rise into the mid 30s on Sunday and up to near 50 on Monday. That high will also act like a shield next week, shunting what looks to be a powerful storm well north of the city on Tuesday.
