The Storm Report Blog For January 20-23, 2013
Left Map Analysis: Looking at the latest satellite image this evening we can see north of the red line that is where the Arctic air is beginning to make its plunge southward. This cold air is bringing temps that range anywhere from -15 to -30F along with Wind Chill values near -50F. This cold air will make a plunge further south-southeastward over the next few days.
Right Map Analysis: The High pressure over Canada that is making its way southeastward is the primary cause for this very bitterly cold air that is moving towards the United States. The news behind this cold air is that it’s some of the coldest air that has been recorded in over four winters for many places in this region as they head into the double digits below zero for the next few days. The white shaded region from Mississippi to the Southern Appalachians also marks the snow swath that pushed through this region this past week. The significance of this snow is that some southern cities such as Jackson, Mississippi and Northern Alabama along with Northern Mississippi have now got more snow that places in the north this winter such as places like Chicago, IL. The white line outlines the region that is going to deal directly with this Arctic air that is moving in over the next few days as mentioned earlier some of these places such as Grand Forks, ND; International Falls, MN and other places will be dealt with dangerously cold weather along with wind chills well below zero nearing -50F.
Looking at the potential impacts of this storm for certain cities and how they will be impacted. (These conditions are for January 19-21).
(Cold Air Impacts below):
Fargo, ND: The 20th will be the start of the cold air moving into the region with overnight lows falling to around -6F along with Northwesterly winds 15-20mph which will lead to Wind Chill values near -30F. The cold will continue into Monday night as overnight low temps will fall to around -19F along with that moderate northwesterly winds will bring wind chill values to near -45F. The cold will carry into a third day as Tuesday morning temps will be around -17F with northwesterly winds of 5-10mph which will create wind chill values near -30F. The fourth and final day of the cold will bring the region overnight lows around -5F along with winds from the Northwest 5-10mph which will make for wind chill values around -20F.

Duluth, MN: The northern region of Minnesota will also be feeling the cold by Sunday morning as low temps will be near -10F with moderate northwesterly winds creating a wind chill near -32F.

Note: This Artic air that is about to hit the region will be some of the coldest air that this region has seen in over 3 winters.
Snow Summary: Another note to take into consideration is the snows of the south this year we have been seeing more snow in some southern cities than the northern cities. The prime example is Chicago, Illinois which has seen less than two inches for the winter, while places around Jackson, Mississippi have seen one to four inches just in this last winter storm along with that is Northern Alabama some places here have now seen near two to five inches of snowfall. This just adds to the craziness of our weather patterns across the United States.
Past 24hr Storm Summary: The high pressure system responsible for all this upcoming cold air has just started to make its way into the Northern Plains as the temps have started to plummet towards zero and below zero this evening already.
24hr Storm Impacts: The next 24hours we will be watching this cold air outbreak start taking shape as the colder air starts to arrive Sunday night into Monday morning when many of those places in the Dakotas and Minnesota start to head into the double digits below zero for overnight lows. This Cold Spell will be in place for a series of four to five days before it starts to moderate in this region. This cold air will also start to push towards the south-east which means as this cold air starts to push into the Great Lakes region it could lead the way to a heavy lake effect snow event by the middle of next week.
