Area forecast discussion, Jun 19, 2:56 PM CDT, 1 hour 49 minutes before
Area Forecast Discussion National Weather Service Lincoln IL 256 PM CDT Mon Jun 19 2017 .SHORT TERM...(This evening through Tuesday) ISSUED AT 224 PM CDT Mon Jun 19 2017 Deep cyclonic flow will linger across central and southeast Illinois through the period. This flow regime, coupled with unseasonably cool temperatures aloft, is supportive of deep diurnal mixing/gusty winds and spotty diurnal convection. The threat for isolated showers and storms will linger for a couple hours early this evening before peak diurnal instability is lost. The threat for isolated showers/storms will return by Tuesday afternoon. The relatively dry air mass in place will help keep storm coverage and CAPE values to a minimum, but the dry air beneath cloud level could support some strong convective wind gusts. && .LONG TERM...(Tuesday night through Monday) ISSUED AT 224 PM CDT Mon Jun 19 2017 Upper-level flow flattens out for the middle of the week, allowing temperatures to climb back above normal. A strong wave is progged to track across Canada within this developing flow regime. Shower/storm chances increase across at least northern portion of the forecast area late Wednesday night into Thursday as an associated storm complex may impact the area. Precipitation chances increase across the entire forecast area Thursday night into Friday as the wave tracks further east across Canada and a trailing frontal boundary settles across the forecast area. Beyond Friday, much more considerable uncertainty enters the local precipitaton forecast. There are differences in exactly where the trailing front eventually stalls, and how often it is activated by disturbances riding along it. Further complicating issues is the potential tropical system over the Gulf of Mexico for late in the week, which may have impacts on the weather pattern locally. Model trends will need to be watched closely as a consensus is hopefully reached sooner rather than later. && .AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon) Issued at 1219 PM CDT Mon Jun 19 2017 Deep mixing will result in gusty west-northwest winds into early evening across the central Illinois terminals. Winds should decouple early this evening, with speeds falling below 10kts for the remainder of the 18Z TAF valid time. Peak daytime heating, coupled with a couple upper-level disturbances, will result in spotty showers or thunderstorms into early evening. Coverage should remain too low to go above a VCSH/VCTS mention at this time. VFR conditions should prevail through the entire forecast period. && .ILX WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...Bak LONG TERM...Bak AVIATION...Bak
