Area Forecast Discussion National Weather Service Lincoln IL 240 AM CDT Wed Jul 23 2014 .DISCUSSION... ISSUED 240 AM CDT Wed Jul 23 2014 Initial wind shift with the cold front has reached roughly along the I-55 corridor as of 2 am, although the drier conditions lag behind a bit with dew points still in the lower 70s northwest past Galesburg. A warm atmosphere, with 700 mb temperatures near 13C on on our evening sounding, and the extended effects of a strong 600 dm 500 mb high over Colorado, have largely kept the air capped over our area. What storms managed to form didn't do much before fizzling. However, a more pronounced line of storms has formed over northern Indiana and northeast Illinois, ahead of the upper level shortwave. This line will be clipping out far northeast CWA before sunrise. The main forecast challenges for this package involves nocturnal convective chances Thursday night and again Friday night. SHORT TERM...Today through Saturday: The front will likely be along the I-70 corridor around sunrise, but may take much of the morning to fully clear the area. Latest HRRR and SPC 4km WRF showing some convection redeveloping immediately along the boundary beginning around 9 am and moving across the southeast CWA the remainder of the morning, so will maintain some 30-40% PoP's in that area through noon. The remainder of the forecast area will see north-northeast winds spreading less humid conditions over the area. Highs across the northeast counties will likely struggle to reach 80 degrees as the cooler air is advected in. Main core of the cooler air arrives tonight as 850 mb temperatures drop to around 11C. Lows of 50-55 expected over the entire forecast area. Currently looks like these will fall a couple degrees shy of records in most areas. Pleasant temperatures to continue through Thursday night. Upper low currently off the Pacific Northwest will be tracking northeast into the southern Canadian prairies through Thursday night, suppressing the high in more of a west-east configuration across the southern states. Increasing low level jet across Iowa expected to form an MCS there Thursday evening, tracking southeast along the 850 mb thermal gradient. The ECMWF is most progressive with bringing the leading edge all the way to Champaign by sunrise, but general model consensus has it still just northwest of the Illinois River by then. Have added some 30% PoP's for late Thursday night in the far northwest CWA, and added PoP's across much of the north half of the forecast area for Friday as the remnants of the MCS pass. Another MCS expected to form a bit further east Friday evening over Illinois, although the NAM is completely dry by that point. Have not made much change to the PoP's for Friday night and Saturday, although the highest chances may need to be shifted a bit further east in later forecasts. LONG TERM...Sunday through Tuesday: The closed upper low is expected to open up into a wave over the weekend, as the high rebuilds along and west of the Rockies. A rather pronounced broad upper trough will prevail a good portion of next week, with another round of cooler air similar to what we'll be seeing over the next 36 hours. Showers and some thunderstorms will be possible Sunday as the wave moves overhead, with chances after that minimal and mainly during afternoon heating. Geelhart && .AVIATION... ISSUED 1156 PM CDT Tue Jul 22 2014 Except for a small period of time overnight when vis will be around 5SM and cigs will be 2.5kft, MVFR, conditions should be VFR for most of the TAF period. The front is still slowly moving through the area, so all TAF sites could still see some storms/showers. PIA could still see something for about an hour, BMI and SPI for 2hrs, DEC for about 3hrs, and CMI for about 2 hrs, though starting around 08z. Once the front goes through, winds get light, and with low level moisture still being high, light fog will be possible at all sites. So have 5SM BR during several hours overnight at all sites. As is being seen at some sites, cigs around 2.5kft could happen, but only going to have a TEMPO group for this. Then expecting some CU development tomorrow, even though drier air is advecting into the area tomorrow. This CU will dissipate tomorrow evening, resulting in clear skies tomorrow night. Winds will be southwest ahead of the front/s, but become light; then northwest behind the front. Expecting north-northeast winds tomorrow, with speeds around 10-12kts during the daytime hours.
