.SHORT TERM...
203 PM CST
Through Monday night...
Main short term forecast concerns revolve around development of
light drizzle/rain tonight, likely resulting in areas of fog as
well. Cooling of the column behind a cold front late Monday also
presents some minor p-type concerns, but without significant
impact as it looks to occur primarily as precip ends.
Early afternoon surface analysis shows weak low pressure passing
north of the Great Lakes in association with a minor-amplitude
short wave transiting the region. A cold front trails southwest
into the Plains, with south-southwesterly low level flow across
the forecast area ahead of the frontal trough axis. A deeper upper
trough across the western CONUS will eject eastward tonight, with
a new surface low developing along the southern end of the cold
frontal trough over the Plains. This low will deepen as it lifts
northeast across far northern IL on Monday, pulling the cold front
through the area during the afternoon and early evening hours.
In the near term, shallow low level moisture continues to slowly
increase across the forecast area this afternoon, seen this
morning in upstream soundings at ILX, DVN and SGF. Patchy low
clouds have developed at times across the cwa during the day in
response to this shallow moist advection. Low level moisture is
progged to deepen across the area tonight, as high pressure ridge
across the Gulf coast states drifts east, and richer moisture
makes its way north into the Midwest. This will present itself
locally as a blossoming of low clouds and eventual development of
drizzle and light rain later this evening/overnight. Saturated low
levels, combined with light precip and diminishing winds in the
weakening gradient ahead of the approaching surface low, will also
like result in fog development overnight. Guidance doesn`t
suggest widespread dense fog (vis less than 1/2SM), though would
expect a considerable amount of 1-3SM type fog into Monday
morning. The axis of strongest moist advection sets of from
central IL into northern IN tonight into Monday, resulting in
generally light (
