Figure 1: Surface map at 2 p.m. on Friday January 29th. The surface low is centered in east central Louisiana with several surface trofs extending north and northeast. Precipitation, in the form of snow, is limited to southern Missouri as strong high pressure across Wisconsin continues to advect dry cold air into the region. (Analysis by Fred Glass)
Figure 2: 850mb Analysis at 6 a.m. Friday January 29th. The low level jet was focused across Oklahoma where deep moisture was being transported. Very dry and cold air was in place across eastern Missouri and Illinois, which ultimately limited the northern extent of the snowfall. (Analysis by Fred Glass)
