Area Forecast Discussion National Weather Service Lincoln IL 352 PM CDT Sun Jul 14 2019 .SHORT TERM...(This evening through Monday) ISSUED AT 345 PM CDT Sun Jul 14 2019 A broken band of showers and thunderstorms was tied to a frontal boundary over northeast IL extending from Dubuque to Kankakee to near Monticello in northern IN. CWA currently has been dry since mid morning. A scattered to broken cumulus cloud field was along and south of a Rushville to Lincoln to Savoy line at mid afternoon with sunny skies over northern CWA north of this cu field. Another hot and humid afternoon across area, with temps in the upper 80s and lower 90s, and heat indices in the 92 to 100 range at 3 pm. Surface map shows 1008 mb low pressure (remnants of Barry) over nw LA while weak 1022 mb high pressure over TN into southeast MO. A frontal boundary was over ne IL (sw of the Chicago metro area) and northern IN. Latest CAMs continue to show isolated convection developing late this afternoon and early evening until sunset over central sections of CWA near northern edge of cumulus cloud field, and lifting slowly NNE toward I-74 early this evening. Carried slight chances of showers and thunderstorms thru sunset, then have dry conditions tonight with muggy lows around 70F. Remnant low pressure from Barry to lift slowly northward into the Ozarks of nw AR by Mon afternoon. This will gradually spread isolated to scattered showers and isolated thunderstorms northward into areas se of the IL river Monday afternoon, with highest pops in areas from Taylorville to Effingham to Olney sw. SPC day2 outlook has a marginal risk of severe storms over far southeast IL from Louisville to Robinson south by late Mon afternoon with low top supercells capable of a brief tornado with bulk shear values near 40 kts. Very warm and humid on Monday with highs in the lower 90s from I-74 north and mid to upper 80s south of I-74, coolest from Jacksonville to Effingham and Lawrenceville south where more clouds and higher convection chances. Heat indices to peak in the mid to upper 90s from I-74 north again. && .LONG TERM...(Monday night through Sunday) ISSUED AT 345 PM CDT Sun Jul 14 2019 Low pressure from Barry tracks into south central MO by dawn Tue and to keep chances of showers and isolated thunderstorms over areas se of the IL river, highest pops in southeast IL. WPC has marginal risk of excessive rainfall from Litchfield to Paris south with slight risk of excessive rainfall in southern IL south of I-64. Lows Monday night around 70F to lower 70s. Remnants of Barry to track ne toward St Louis area late Tue afternoon. This will bring the highest pops to central and southeast IL on Tue with likely pops se half of CWA by Tue afternoon with chances pops along and nw of I-55, though slight pops far nw by Galesburg. WPC day3 outlook has marginal risk of excessive rainfall from I-55 se and slight risk of excessive rainfall in southeast IL where up to 2 inches of rain possible near the Wabash river. Still have likely pops over southeast IL Tue evening then diminishes to 20-40% pops in eastern/se IL overnight Tue night. Highs Tue in the low to mid 80s, coolest in southeast IL, with upper 80s nw of the IL river. Chances of showers and a few thunderstorms lingers in eastern/se IL on Wed as surface low pressure tracks ne into east central IL by midday Wed and upper level trof shifts east of IL. Highs Wed in the upper 80s to near 90F in eastern IL and lower 90s west of I-57. The 12Z forecast models build a subtropical mid and upper level ridge into the area Thu thru next weekend and likely bringing the strongest heat wave to the area this season. Will eventually likely need heat headlines late this week as highs reach the 90s and afternoon heat indices reach near or above 105 degrees Thu thru Sat. Convection chances look very spotty from Wed night into next weekend with some isolated chances of convection at times over mainly areas north of I-74. Main forecast concern will be the high heat and humidity. && .AVIATION...(For the 18Z TAFS through 18Z Monday afternoon) Issued at 1245 PM CDT Sun Jul 14 2019 VFR conditions are forecast to continue across the central IL airports through 18Z/1 pm Monday. Scattered to broken cumulus clouds with base of 5-7k ft to occur this afternoon until sunset and redevelop again after 15Z/10 am Monday. Can not completely rule out isolated shower/thunderstorms later this afternoon and into mid evening from I-72 south and ne of I-74, but feel coverage is too limited to mention in TAFs at this time. A frontal boundary was lifting back ne toward Chicago metro early this afternoon. Meanwhile a 1009 mb low pressure (remnant of Barry) was over nw LA early this afternoon and to lifting slowly northward into west central AR by 18Z/1 pm Mon.
