    February 17th, 2019 Snow Event

    LOT update .UPDATE... 909 AM CST Snowfall rates have been impressive within pockets of moderate to briefly heavy snow this morning across the NW half of the CWA. Various reports indicate 1 to locally 3 inches has already fallen within an axis from Lee to Lake(IL) counties. Snow ratios under the heaviest snow bands appear to be 20:1 or even slightly higher. Much of this is being forced by a combo of low-level WAA/isentropic lift with some assistance from an upper trough axis wrapping around the upper low over NW IA. A notable back edge to the heavier precip rates tied to the upper trough axis is currently across the southern CWA counties and should clear the northern CWA by noon. Given the heavier snow rates across the northern Chicago Metro, had considered expanding the winter weather advisory to Kane/DuPage/Cook counties. However, with a majority of the accumulation having already occurred, higher impacts remaining confined to mainly the morning hours, and the expectation for only light snow to continue this afternoon and evening, felt an SPS was a better option to message the ongoing heavier snow.

    National Weather Service Milwaukee/Sullivan WI 826 PM CST Mon Feb 11 2019 .UPDATE...Will be upgrading Milwaukee, Waukesha, Jefferson and Rock counties to a Winter Storm Warning shortly. Too much evidence from Model Certainty and Probablistic snow totals for amounts in these areas from 6 to 8 inches. In addition, am concerned about a period of freezing rain/drizzle Tuesday morning as ice stops falling into the cloud layer for several hours. Concerns over persistent lift from lake enhancement affecting parts of Milwaukee county later tonight into Tuesday morning. All guidance also takes 850H circulation across far northeast Il late tonight, which places parts of Rock and Jefferson counties in favorable track for heavier snow. Will leave Walworth, Kenosha and Racine in advisory for now. Widespread snow continues to spread northeast across the CWA this evening. Strong coupled jet structure and aloft and a period of impressive sloping frontogenetical forcing in the low levels overnight. One troubling piece is that the best low level forcing from the frontogenesis does not intersect the better dendritic growth zone.

    Winter Storm - February 11-13, 2019

    LOT update National Weather Service Chicago/Romeoville, IL 737 PM CST Mon Feb 11 2019 .SHORT TERM... 734 PM CST Through tonight... Only modest changes to going forecast so far this evening. Guidance is struggling with the northern extent of the warm nose this evening. Several raob soundings over the area indicate temperatures within the warm nose over Chicago to be between 0.5 and 1.5C, sufficient for partial if not full melting aloft. Surface obs indicate some sort of wintry mix that includes liquid precip over all but the northern tier of counties in the CWA. Adjusting temperatures aloft accordingly brings the wintry mix farther north across the CWA and nets slightly lower snow totals and higher ice totals between the I-80 and I-90 corridors, and tightens the snow gradient in that area. Little change was made farther north which is expected to remain primarily snow.
