SYNOPSIS. Issued at 330 PM CST Sun Jan 19 2020

Very cold conditions will persist across central Illinois tonight with temperatures remaining steady in the single digits and teens A few flurries will be possible as well. particularly during the evening.

SHORT TERM. (This evening through Monday) ISSUED AT 330 PM CST Sun Jan 19 2020

A short-wave trough extending from New York to north-central Illinois has resulted in a band of low clouds/flurries across the KILX CWA this afternoon. Partial clearing has occurred in the wake of the wave across southern Wisconsin into northern Illinois: however, this clearing has been making very little progress southward over the past couple of hours. HRRR has been consistently showing the clouds clearing from north to south late this afternoon into early this evening, but based on satellite trends think this is too aggressive. Think partial clearing will occur along/north of a Peoria to Bloomington line this evening, with mostly cloudy conditions holding firm further south across the remainder of the area. May even see a few snow flurries through the evening . as evidenced by several 21z/3pm obs along the I-74 corridor. Thanks to the cloud cover and continued northwesterly winds, temperatures will remain nearly steady in the single digits and teens.

Next weather-maker is already evident on latest water vapor imagery over southwest Manitoba. This wave is progged to dive southward over the next 24 hours, with the strongest lift skirting central Illinois to the W/SW Monday afternoon. Despite both the 12z and 18z HRRR keeping measurable precip well to the west across northern/central Missouri, other models such as the 12z WRF-ARW and 18z NAM bring very light amounts to the far southwest CWA. With the wave tracking so close and the very cold airmass remaining in place, would not be surprised to see light snow along/southwest of a Macomb . to Springfield . to Effingham line. Any accumulations will be limited to a dusting, with a few tenths of an inch further west along/west of the Mississippi River. High temperatures will range from the teens in the Illinois River Valley to the middle 20s near the Indiana border.

LONG TERM. (Monday night through Sunday) ISSUED AT 330 PM CST Sun Jan 19 2020

Temperatures will steadily warm through the middle of the week, with highs climbing back into the upper 30s to around 40 degrees by Wednesday. After that, a stronger system will come into the picture for the middle and end of the week. Models have consistently been showing a slow-moving southern stream feature spreading clouds and light precip into west-central Illinois perhaps as early as Wednesday night . with the main flux of precip holding off until Thursday night into Friday. While light snow accumulations will be possible both Wed night and Thursday night, temperatures will be too warm to support snow during the day . as highs approach 40 on Thursday, then rise into the lower to middle 40s on Friday. End result, will be an extended period of off-and- on light precip Wednesday night through Friday night . mostly in the form of rain.

AVIATION. (For the 00Z TAFS through 00Z Monday evening) Issued at 543 PM CST Sun Jan 19 2020

MVFR cigs are in place across the central IL terminals although partial clearing is working its way southward from northern IL. This clearing is expected to reach KPIA and KBMI within an hour or two, however sites to the south are more debatable and may take several hours to see partial clearing. Additional cloudiness is likely to arrive overnight: from lake-effect from Lake Michigan at KCMI, and from a weather system dropping southward out of Manitoba. Scattered snow flurries with little or no visibility impact can be expected early this evening, and additional flurries or snow showers may impact KSPI vicinity after 17Z Monday from the approaching weather system. Winds NW 9-14 kts initially, slowly decreasing to 5-10 kts overnight.

ILX WATCHES/WARNINGS/ADVISORIES. NONE.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
