Lake effect snow forecast 3″ to 10+” between Arlington Heights and Evanston and south near the lake – Cardinal News

Lake Illinois County winter storm warning also

The forecast could change again, but currently 3.3 inches of snowfall is forecast for Arlington Heights between approximately 1:00 a.m. and 12:00 p.m. on Friday, January 28, 2022.

Compared to this afternoon’s outlook, the NWS Office Chicago has forecast a change in the impact of Lake Effect Snow (LES) – moving from northwest Indiana into the city of Chicago, and the western and northwest suburbs and Lake County, Illinois. A winter storm warning was issued at 9:13 p.m. for Lake County ILLINOIS, central and northern Cook counties. A winter weather advisory is activated for DuPage County, Southern Cook County and Lake Indiana County. This is mostly a flip from the Thursday afternoon forecast. Lake-effect snow bands are difficult to predict, and as impact weather nears, the snow band is expected to hit Chicago and its suburbs more than Indiana. The snowfall forecast remains tentative as the lake effect snow band could displace the impact into northeast Illinois.

With respect to the synoptic and thermodynamic Lake Effect Snow (LES) environment, there is no change from the intensity of the snowfall rates of the previous impact zone – it is just that the impact zone has moved further north and west in this update. According to the NWS office in Chicago, there is a favorable environment for a band of dominant and intense unique lake-effect snow to develop and move ashore in northeastern Illinois on Friday morning. . Forecast soundings show a convective layer encompassing the entire dendritic growth zone (DGZ) and, given the high instability and expected land breeze convergence band, should see strong uplift through the DGZ. The pattern looks favorable for snowfall rates of 2″+ per hour during the most intense part of the LES band (09z-16z).

There was an almost unanimous westward shift in high-resolution guidance in the placement of the Lake Effect Snow (LES) band, which places the risk of heavy snowfall further north in the Chicagoland metro area in location in northwestern Indiana. Unfortunately, there are inherent uncertainties that come into play when trying to predict meso-gamma scale phenomena like this, according to NWS Chicago. It’s also not uncommon for snow bands to “wiggle” and there’s still some scatter in the various high resolution tips on LES band placement. Although further changes in the planned placement of the band are possible, the NWS has reported that the time window has arrived for a decision to be made, so the NWS office in Chicago has steered higher snow accumulations further north and west, but not as far north and west. like most 00z high res guides.

Moving the orientation westward actually increases the confidence that there might be a longer dwell time for some areas. In other words, the LES band could sit on areas for a longer period of time. Confidence is growing that maximum snowfall totals somewhere in Chicagoland will end up at least in the 6-8″ range and double-digit totals could even occur. Given the timing of this event (at the height of the Friday morning rush hour) and the inherent uncertainties of the exact placement of the LES tape, the NWS Office Chicago chose to err a little on the side of caution with large titles, saying it’s certainly plausible that the LES gang ends up just east of Lake County IL and/or Dupage County, or stays mostly west of Lake County, Indiana. The NWS office in Chicago said it decided to go with a forecast with the slightest regret was to release a bigger headline and the risk that the headline for some areas overestimates rather than underestimates.

URGENT Winter Storm Warning – WINTER WEATHER MESSAGE National Weather Service Chicago IL 913 PM CST Thu Jan 27 2022

ILZ104-281115- /O.UPG.KLOT.WS.A.0003.220128T0600Z-220128T1800Z/ /O.NEW.KLOT.WS.W.0002.220128T0800Z-220128T1800Z/ Central Cook- including the cities of Chicago, Cicero, Oak Lawn , Oak Park and La Grange 9:13 p.m. CST Thu Jan 27, 2022

…WINTER STORM WARNING IN EFFECT FROM 2 AM TO NOON CST FRIDAY…

* WHAT… Heavy lake effect snow is expected, with snowfall rates of 2 inches or more per hour possible at times. The highest snow accumulations will likely be between 4 and 8 inches. The nature of lake effect snow is such that snow intensity can vary significantly over just a few kilometres. Areas not directly impacted by the heaviest band of snow will likely end up with much less than 4 inches of snow.

* WHERE…Central Cook County.

* WHEN… 2:00 a.m. to noon CST Friday.

* IMPACTS… Conditions will be highly variable, potentially ranging from light showers to near white conditions in heavy snow for just a few miles. Under the heavy snow strip, travel is likely to be extremely difficult, including during the height of the Friday morning rush hour.

*ADDITIONAL DETAILS… The intense portion of the lake effect snow band will result in visibilities of a quarter mile or less and rapid accumulation rates, at times exceeding 2 inches per hour. Snowfall rates of this magnitude, especially in traffic jams, can be very difficult for snowplows to track. If travel cannot be rescheduled, plan for significantly longer travel times in areas with the heaviest snowfall.

PRECAUTIONARY ACTIONS/PREPARATION…

If you must travel, keep an extra flashlight, food, and water in your vehicle for emergencies.
