ESFLOT A strong storm system moving across the region through Wednesday will lead to additional rounds of rainfall. Total rainfall amounts of at least 1 inch will be widespread by Wednesday morning, with amounts near 2 inches in isolated areas. Although river levels remain below average, soils across the area remain partially frozen from recent periods of cold weather. The upper few inches of soil have started to thaw, but infiltration will remain limited. Runoff will collect in poor drainage areas, ditches, fields, and yards, with stream and river rises to near bankfull possible. Isolated areas of minor flooding may occur where rainfall is heaviest. This outlook means that elevated water levels and potential impacts are possible, but not yet certain. Persons should closely monitor forecasts including the possibility of flood watches, warnings, and advisories. This will likely be the final statement for this event.
ESFLOT A strong storm system will move through the region Tuesday into Wednesday leading to multiple waves of soaking rainfall. The highest rainfall rates are expected Tuesday morning and again Tuesday evening. Total rainfall amounts of at least 1 inch will be widespread by Wednesday morning, with amounts near 2 inches in isolated areas. Although soil moisture and river levels remain below average, soils across the area remain deeply frozen from recent periods of cold weather. The frost depth of 11 inches measured today at NWS Chicago is above average for this time of year, and may also contain elevated soil moisture, frozen in place near the soil surface, from earlier rainfall and snow melt. The upper most few inches of soil may begin to thaw prior to the onset of rainfall, but infiltration will be limited. River ice spotters and recent satellite imagery indicate that heavy river ice cover has mostly melted since last week, with only a few isolated areas of heavy ice cover remaining on portions of the Pecatonica, Fox, and Vermilion rivers. Due to the limited amount of ice cover, it is very unlikely that ice jams will impact the flood risk from this rain event. Runoff will quickly collect in poor drainage areas, ditches, fields, and yards, shortly after the onset of rainfall, with stream and river rises to near bankfull possible. Isolated areas of minor flooding may occur where rainfall is heaviest. This outlook means that elevated water levels and potential impacts are possible, but not yet certain. Persons should closely monitor forecasts including the possibility of flood watches, warnings, and advisories. The next scheduled update to this outlook is tomorrow morning.
* WHAT...West-northwest winds 25 to 30 mph with gusts of 45 to 50 mph. * WHERE...Portions of central, east central, north central, and northeast Illinois and northwest Indiana. * WHEN...Until 9 PM CST /10 PM EST/ this evening. * IMPACTS...Gusty winds will blow around unsecured objects. Tree limbs could be blown down and a few power outages may result. * ADDITIONAL DETAILS...While wind gusts have temporarily eased in some areas early this afternoon, expect them to quickly increase again from the west-northwest through the afternoon following a cold frontal passage.
* WHAT...Westerly winds 20 to 25 mph with gusts up to 45 mph expected. * WHERE...Central Cook, DuPage, and Northern Cook Counties. * WHEN...From 9 AM to 6 PM CST Friday. * IMPACTS...Gusty winds will blow around unsecured objects.

Strong southwest to west-northwest winds, low relative humidities, and unseasonably mild temperatures will result in a heightened fire danger this afternoon over northern Illinois and northwest Indiana, especially south of I-80. Quicker drying and dormant fuels like brush and grass will be particularly susceptible to ignition with strong winds likely leading to the rapid spread of any fires that do occur. Use caution with the disposal of smoking materials and consider postponing any outdoor burns to a different day.

ESFLOT Favorable conditions for river ice development and possible ice jams will exist through today and then return early next week, impacting the Rock, Fox, Des Plaines, and Kankakee river basins. Very cold temperatures, favorable for rapid formation of river ice on most areas rivers, will continue through today. After a brief warm-up on Saturday, an additional period of very cold weather is expected to arrive early next week. Area river gauges indicate likely ice effects and a few minor ice jams, although no flooding appears imminent at this time. New and worsening river ice cover remains possible into tomorrow, which may lead to rises on area rivers with little warning. A multi-day period of very cold temperatures next week will likely bring another period of favorable conditions for heavy river ice and ice jams. No additional updates to this product are scheduled at this time, but may be required prior to early next week if temperature forecasts continue to indicate favorable river ice conditions.

A band of light precipitation will move across northern IL and parts of far northwestern IN overnight. The precipitation should onset as a period of light snow, but will likely mix at times with freezing rain before tapering off and changing over to some light drizzle by daybreak Sunday morning. Temperatures will be hovering around freezing for several hours overnight, so some slick travel conditions may develop for a few hours overnight before temperatures warm above freezing by daybreak.
ESFLOT While unseasonably mild temperatures this week will continue to facilitate some melting and breaking up of the ice, significant amounts of ice may remain in many rivers late this week. A storm system is expected to bring rainfall to the region late Thursday into Friday. While there is still uncertainty in where the heaviest rain will fall, current indications are that many areas will see at least a quarter to half inch of rain, with localized amounts possibly exceeding one inch. The measured soil frost depth Wednesday morning was still 12 inches with no near surface thaw. Soil temperature sensors from the Illinois State Water Survey confirm frost depths of at least 8 inches exist across the entire area. Even with mild conditions, any thaw that takes place will likely remain shallow, which could minimize infiltration into the ground of rain later this week. Rather, most of the rain should runoff into area streams and creeks resulting in an increase in streamflow. Even a modest increase in streamflow could break up and dislodge river ice, leading to an increased risk of localized ice jam flooding. This outlook means that locally elevated water levels due to ice jams are possible, but not yet certain. Persons living in areas prone to experience ice jam flooding, particularly along the Kankakee, Rock, and Fox Rivers, should closely monitor later forecasts.
