Area Forecast Discussion National Weather Service Lincoln IL 322 PM CDT Thu Jul 29 2021

SYNOPSIS. Issued at 322 PM CDT Thu Jul 29 2021

Scattered thunderstorms will develop late this afternoon and move south to southeast across the area. Ahead of these storms, hot and humid weather is expected with heat index values around 105 expected through 8 pm. Once the rain ends tonight, mostly clear skies are expected with overnight lows dropping into the 60s.

SHORT TERM. (This evening through Friday) ISSUED AT 322 PM CDT Thu Jul 29 2021

Still expecting scattered storms to develop along a weak cold front dropping into the CWA from northern IL. However, continued elevated convection in the northern part of the area has kept a dense cirrus shield over the area and this has limited instability over the area and slowed the eroding of the cap. MLCIN is still 50-150 over the central part of the CWA where the best convergence is located at along the outflow boundary. HiRes models have had trouble with reality, and this has not boosted confidence in possible outcomes rest of the afternoon and evening. Still believe something could develop along the front once it gets into the 3500-4000 j/kg instability axis near I-74 so will keep chance of storms over the CWA for late this afternoon through this evening. Storms that do develop could still produce hail and damaging winds, and move south-southeast this evening. Believe precip should be south of the CWA around midnight and then expecting dry weather to continue through tomorrow. Hot and humid conditions will also continue even though some areas have seen dense cloud cover. So, the heat advisory will be allowed to continue through 8 pm. Overnight lows are expected to fall into the 60s given the precip moving south of the area and cooler air advecting into central IL. Tomorrows highs will be much cooler as well, only reaching to around 80. Conditions tomorrow should be less humid, but any place that sees rain this evening could see some light fog.

LONG TERM. (Friday night through Thursday) ISSUED AT 322 PM CDT Thu Jul 29 2021

After a brief break in the precip Friday evening, another boundary will setup near the western part of the CWA and bring more storms for late Fri night through Sat night. Models differ on how close into the CWA this boundary will setup but looks like most of the precip should be southwest of I-74. Dry weather is then expected for the remainder of the weekend and through next week. Temps will also be on the cooler side, with highs in the upper 70s to into the 80s.

AVIATION. (For the 18Z TAFS through 18Z Friday afternoon) Issued at 1246 PM CDT Thu Jul 29 2021

Models not handling the current storm situation very well so location of mesoscale features will be the key to the forecast. Scattered storms still popping in the north near PIA and moving toward BMI this afternoon but rest of the area is just seeing either light rain or high based clouds. Atmosphere is becoming increasingly more unstable, but it remains capped over most of the area. The outflow boundary is down near I-72 while the front is still in northern IL. Once cap erodes and front arrives, storms will develop again . first at PIA, then BMI and then moving south toward SPI/DEC/CMI. Have included TEMPO groups for all sites at best guess of 3hr period when convection is possible at each site. Otherwise VCTS for 1-2hrs after the TEMPO groups. After precip, clouds should scatter out and fog should develop getting as low as 4sm with 2sm tempo in the morning. Winds will be west to southwesterly and then becoming northwest after precip and the light and variable overnight through morning.

ILX WATCHES/WARNINGS/ADVISORIES. Heat Advisory until 8 PM CDT this evening for ILZ027>031-036>038- 040>057-061>063-066>068-071>073.
