(10:00PM - 11/10/19) A snowstorm will bring widespread accumulating snow to much of the state, this evening through Monday evening. This will be the biggest Veterans Day snowstorm on record for some areas.
Model guidance continues to be in good agreement regarding this event, and early observations support the overall idea. Have generally maintained similar forecast to our last two updates, bit will hit harder the idea of locally higher amounts being possible across Northern Illinois.
An area of snow is expected to spread across Northern Illinois within the next several hours. Snow will then continue overnight and into Monday morning, before ending late Monday morning and early Monday afternoon. Snow will also spread across portions of Central Illinois, affecting this area from early Monday morning through later Monday afternoon. Across Southern Illinois, rain will turn to snow late Monday morning or early Monday afternoon, then continuing through Monday evening. Much of the state will see final snowfall accumulations upwards of 1-3". A heavier swath of accumulations of 3-6” will be likely across much of Northern Illinois, with locally higher amounts in excess of 6" possible. Additionally, lake effect and lake enhancement will be possible for areas of Northeast Illinois near Lake Michigan.
