We have been stuck in a cold blast for almost 2 weeks! Low temperatures have only reached average once since December 4th.
A strong high pressure is to blame for our cold weather, but with a larger storm on the horizon things will begin to change the next few days. A low pressure starting over Colorado on Thursday will move our way arriving Thursday night/ Friday morning. Before then, winds out of the south will warm temperatures above average.
The big question right now is what type of precipitation will fall on Thursday & Friday. Right now it looks to be a mix starting as rain, possibly switching to freezing rain and ending as snow. Precipitation amounts don’t look to be too significant, but if colder air creeps in it could be our biggest snowfall so far this season.
As the low pressure moves east another arctic high pressure moves over the upper Midwest bringing another blast of cold air.
One interesting stat to note: with two weeks left in 2013, the year is currently the 5th wettest on record at Rochester International Airport (the climate station for SE MN). With a few more storms we could easily move into the top 3.
