Mesoscale Discussion for McHenry Co., IL

<pre>ACUS11 KWNS 260054 SWOMCD

Mesoscale Discussion 1664 NWS Storm Prediction Center Norman OK 0654 PM CST Sun Nov 25 2018

Areas affected…Northern IL and adjacent portions of Eastern IA/Southern WI

Concerning…Blizzard

Valid 260054Z – 260700Z

SUMMARY…Heavy snow will spread into a larger portion of northern IL this evening. As stronger winds move in from the west, blizzard conditions will expand later tonight across the region.

DISCUSSION…00Z surface analysis depicts a 993 mb surface cyclone just northeast of St. Louis. To the north and northwest of the low, heavy snow is ongoing from northeast MO into northwest IL, with stronger winds in the northwestern quadrant of the cyclone producing blizzard conditions. Dual pol products from KILX/KLOT and recent surface obs and mPing reports indicate that the rain/snow line is moving eastward across northern IL, and this trend is expected to continue as backing surface winds result in increasing low-level cold advection to the north and northwest of the east-northeastward moving surface low. Snow should continue spreading into most of the Chicagoland area between now and 02Z, though areas in the immediate vicinity of Lake Michigan may see a longer period of mixed precipitation as northeasterly winds off of the lake maintain a slightly warmer near-surface layer.

Substantial convection has been noted near the surface low moving into southern IL, with a convective character to the precip (and some thundersnow reports) also noted within cooling cloud tops across northern IL. Strong low/midlevel frontogenesis will continue to favor moderate-to-heavy snow to the north of the midlevel low, with some convective enhancement possible just north of the midlevel dry slot, where relatively steep lapse rates (in excess of 7 C/km as noted on ILX/DVN 00Z soundings) will be maintained. Snow rates of 1-3 inches per hour are expected within the primary snow band, which should shift gradually eastward into northeast IL by late tonight.

Strong winds (gusts in excess of 40 kt) are resulting in ongoing blizzard conditions from northeast MO into northwest IL. These stronger winds will expand eastward with time tonight in conjunction with the movement of the surface low, resulting in an expansion of blizzard conditions into northeast IL and perhaps far southeast WI after 03Z tonight.

Hazardous Weather Outlook for McHenry Co., IL

<pre>FLUS43 KLOT 252218 HWOLOT

Hazardous Weather Outlook National Weather Service Chicago/Romeoville IL 418 PM CST Sun Nov 25 2018

This Hazardous Weather Outlook is for portions of North Central Illinois…Northeast Illinois and Northwest Indiana.

.DAY ONE…Tonight.

Weather hazards expected…

Limited Thunderstorm Risk south and east.  Elevated Non thunderstorm wind Risk.  Extreme Snow Risk.  Significant Lakeshore Flood Risk

DISCUSSION…

A powerful winter storm will bring blizzard conditions and very heavy snow to portions of the area. Accumulations will exceed a foot in some areas, including across the northwest suburbs and portions of north central Illinois. Most importantly, conditions will deteriorate rapidly this evening from northwest to southeast. Snowfall rates will exceed 2 inches per hour tonight which will allow for quick accumulation on roadways. Winds during the heaviest snow will reach 40 to 50 mph, and this will make travel dangerous to near impossible in some locations. Amounts will vary right along the lakeshore where temperatures are warmer. Strong onshore winds will also produce large waves and lakeshore flooding along the Illinois and Indiana Lake Michigan shores.

Thunder may accompany some of the precipitation this evening, especially along and southeast of Interstate 55.

.DAYS TWO THROUGH SEVEN…Monday through Saturday.

Monday…

Limited Excessive Cold Risk.  Elevated Non Thunderstorm Wind Risk.  Limited Snow Risk.  Significant Lakeshore Flood Risk

Tuesday and Wednesday…

Limited Excessive Cold Risk.

DISCUSSION:

Snow will taper in the morning, with gusty winds to start the day.

.SPOTTER INFORMATION STATEMENT…

Spotter reports of snow and blizzard conditions will be appreciated, though spotters are not encouraged to drive out in the dangerous conditions.
