Northern Illinois and southern Wisconsin have been split between winter
storm systems to the north and to the south the past couple of weeks,
leaving us with very little snowfall locally. Roughly 1-3 inches of
snow is currently on the ground from Missouri to central Illinois, while
close to a foot of snow remains over the Upper Great Lakes. A changing
pattern in the jet stream will allow a warmer air mass to be pulled
north late in the week, weekend and early next week pushing temperatures
into the upper 40s, possibly close to 50 degrees.
The warming temperatures, however, may create a little more fog and
cloud cover across the Stateline in the days to come. As the warm air
moves over the snowpack to the south, the snow will melt adding moisture
into the atmosphere. This added moisture will lead to the potential
for the development of fog during the overnight as temperatures cool
closer to the dew point temperature. If any fog develops it likely
wouldn't last long as there will be quite a bit of dry air in the
atmosphere located a few thousand feet above the surface.
