Synopsis.. Strong high pressure of 30.7 inches over northern missouri will move into the ohio river valley today. Southwest winds will begin to increase, with gales expected over the northern third of the lake early this evening through Wednesday evening. Winds will briefly weaken on Thursday before low pressure approaches from the west. This will initially result in easterly winds late in the week, possibly becoming northerly heading into the weekend as the low passes south of the region. && lmz080-567-669-671-673-675-777-779-868-870-872-874-876-878-212230- lake michigan from michigan city in to st.

Area Forecast Discussion National Weather Service Chicago/Romeoville, IL 231 PM CST Tue Jan 21 2020

SHORT TERM. 230 PM CST

Through Wednesday .

High pressure centered over the lower Ohio Valley will drift eastward tonight which will help keep a steady southwesterly wind in place for most areas. This will result in a milder night than last night, with lows in the upper teens west to lower 20s southeast. Some sites may warm a few degrees overnight thanks to the breeze and incoming mid/high level cloud cover, especially west. Breezy south-southwest winds will develop Wednesday morning with cloud cover thickening through the day from west to east. Upper ridging will cross the area through the day with modest warming aloft which will lead to highs in the low to mid 30s. An upper trough will be on the heels of the ridge with surface low pressure developing across the high plains. Light snow may try to develop into far northwest sections of the forecast area west of I-39 late Wednesday afternoon.

MDB

LONG TERM. 405 AM CST

Wednesday through Monday .

Longer term forecast continues to focus on the expected development and evolution of a deep closed upper low across the region, and the likelihood of a prolonged period of light to moderate precipitation across the forecast area from late Wednesday through Saturday. While medium-range guidance remains in decent overall agreement with the general pattern, there remains considerable spread in the details of the evolution of the closing off of the upper low, and the exact track of the low across the Midwest. This lends an overall lower confidence to the details of the forecast, including precipitation type and amounts.

On Wednesday, the initially open trough will be propagating eastward across the Plains, while a northern stream disturbance tracks well north of the region across Ontario. A surface cold front trails from this northern stream wave into the Plains, with guidance in overall good agreement in lifting a small amplitude shortwave northeast along this baroclinic zone on the forward periphery of the Plains upper trough. This induces enhanced southwesterly flow into the region Wednesday and Wednesday night, as this lead disturbance propagates across the area. Low levels are initially quite dry, seen in large dew point depressions below roughly 600 mb in forecast soundings. While the strongest moisture advection remains mainly west of the forecast area initially, persistent 30-35 kt 850 flow is indicative of warm advection, and isentropic progs in the 295-305 K layer depict increasing isentropic ascent and moistening. Saturation develops from the mid-levels downward Wednesday evening/night, with light precipitation eventually reaching the surface and spreading eastward with time through Thursday morning. Forecast soundings from various models depict thermal profiles mainly supportive of all snow, though the GFS continues to be warmest with a subtle +0.5 to +1.0 degree warm nose between 900-850 mb in our southern cwa Wednesday night. Have generally favored the consensus of the in the similar NAM/CMC and ECMWF in keeping the profile cold enough for just snow. This would support some minor accumulations mainly west of Chicago and the I-55 corridor by Thursday morning.

While the initial short wave lifts northeast of the area Thursday morning, the upper trough to our west deepens during the day as additional energy digs into it across the Plains. This results in somewhat weak but persistent forcing for ascent during the day, which looks to maintain the threat of continued light precip. Thermal profiles become marginal for snow near the surface during the day with marginal diurnal/warm advection warming into the 30s, making p-type likely a mix of rain/snow. Forcing then strengthens Thursday night and Friday as the low closes off and tracks eastward into the lower Ohio Valley. The GFS remains farthest north with the track of the mid-level circulation and resulting surface low, though the NAM and CMC have trended slightly north of their previous runs. As mentioned previously, this lowers confidence particularly in precip type Thursday night into Friday, with the profile already somewhat marginal, especially across south/southeastern parts of the cwa where low level southeast flow will provide the most warming. Surface temps will generally be close to freezing, suggesting the potential for snow/rain or freezing rain into early Friday. Northwest parts of the cwa will have a better potential for remaining primarily snow with some continued accumulation, though even there we may see a snow/rain mix during the day Friday. The upper low will then slowly drift east of the region through Saturday, with the column eventually cooling enough for precip to change over/end as some light snow. Low level thermal details will undoubtedly come into clearer focus as models narrow in on a solution over the next couple of days.

High pressure then builds into the region Sunday/Monday, though with temperatures still fairly mild and above average given the lack of cold air with the closed off nature of the departing storm.

AVIATION. For the 18Z TAFs .

No forecast concerns through Wednesday afternoon. High pressure crossing the area today will allow for southwesterly winds of around 10 kt this afternoon. Steady southwest winds continue tonight and turn a little more south-southwest or even south Wednesday morning. Gusts to around 20 kt are expected by Wednesday morning. VFR ceilings will lower from the west Wednesday afternoon. Further lowering to MVFR or lower is expected Wednesday evening/night with light snow chances increasing.
