As a fast-moving cold front moves east through Indiana, Chicago will be the recipient
of cold air and snow showers riding blustery northwest winds. Early morning may well
see some snow accumulate on grassy areas to the north and northwest. Commuters
could also experience slick spots on some untreated roads as temperatures fall below
freezing. By this afternoon, sun may emerge as snow showers diminish to occasional
flurries.
Cold high pressure will hold through Tuesday, and then a slight warming should occur
midweek. In fact, Thanksgiving Day may be the warmest of the week, just ahead of the
next surge of cold air expected Friday.
STORM TRACK OVER SOUTHERN U.S.
For the next couple weeks, the primary jet stream aloft and main storm track will flow
west-to-east through the southern United States.This will most likely mean slight
precipitation and on the average cooler-than-normal temperatures for southern
Wisconsin, northern Illinois, and northern Indiana. However, it may foretell trouble for
southern California, where recent fires have denuded ground cover, leaving the area
susceptible to heavy rains, the first of which may occur Tuesday.
