National Weather Service Chicago/Romeoville, IL 305 PM CST Sat Jan 11 2020 .SHORT TERM... 305 PM CST Through tonight... ...Winter Weather... Our period of heavy snow this evening continues to be main focus of the forecast this afternoon. A band of moderate to heavy snow has been ongoing over parts of western MO the last couple hours. This is the the area in which the strongest large scale and mesoscale forcing for ascent are coinciding as the main mid/large scale impulse shifts eastward. This heavy snow has produced up to 1" inch per hour rates for the past few hours at KMCI (Kansas City), with a total of 3 inches of snow within only as mainly hours. Visibilities were also reported to drop briefly to 1/8 of a mile in heavy snow. Given these upstream trends, I see no reason why our area will not experience similar conditions this evening as the main upper level impulse moves over our area. In fact, the dynamics over our area this evening could even end up being a bit stronger than those observed over western MO. This is because the main mid-level trough is expected to begin to take on a bit of a negative tilt as it approaches the area this evening. This in turn should help sharpen the lower level circulation pattern, and result in an enhanced band of low-mid level frontogenesis. The strong dynamics will also coincide with a corridor of steeper mid-level lapse rates, which will also aid in heavier banding. Overall, while light precipitation has been ongoing across the area for much of the day, expect more substantial precipitation to rapidly blossom over the area over the next few hours, as the better dynamics begins shifting over the area. The precipitation will likely begin as a wintry mix of sleet, snow and possibly some rain, especially along and east of the I-55 corridor. The snow will be moderate to heavy at times, especially between 6 and 9 pm this evening, when 1" per hour rates are likely. North- northeasterly winds are expected to ease a bit during the period of heavy snow, though they will likely remain gusty up around 30 to 35 mph, especially near the lake. For this reason, some blowing and drifting snow could aid in significantly reducing visibilities for a period this evening. Total snowfall amounts of 3 to 5 inches are likely, with the highest amounts expected right across northeastern IL. Lighter amounts are likely farther to the south and east into northwestern IN. The snow is still expected to tapper off from southwest to northeast shortly after midnight.
