DISCUSSION
Issued at 336 AM CDT Tue Apr 23 2024

Radar imagery early this morning shows spotty showers over parts of the state. Most of this is struggling to reach the ground due to dry low to mid-level air. Forecast soundings show a wing of moisture associated with a mid-level shortwave advecting into the area shortly after daybreak, which is when we should start to see more precipitation reaching the ground. Showers and isolated storms will persist through this afternoon, gradually shifting southeast through this evening. High resolution convective allowing models have shown a secondary line of widely scattered showers and storms developing just ahead of a southeastward progressing cold front later this afternoon into early evening north of I-72. Instability will be minimal due to the overall lack of moisture, but favorable wind shear and steep low to mid-level lapse rates could support a few storms capable of gusty winds and small hail. QPF through tonight looks to range from 0.25 to 0.50 inches.

Surface ridging spills into the area for the middle of the week, turning temperatures cooler. Overnight lows Wednesday night into Thursday morning will dip down into the middle 30s to low 40s, posing a threat for frost. The highest chances for frost development will be near and north of a Macomb to Mattoon line where the NBM has a 40-80% chance for temperatures being 37 degrees or colder.

The cool snap will be short lived with upper ridging bringing warmer temperatures back into the area by the end of the week. Temperatures will gradually warm through the weekend, approaching 80 degrees in spots by Saturday. A series of upper impulses will bring an extended period of active weather Friday through the weekend characterized by storms, heavy rain, and some severe weather. The first shot arrives late Thursday night into Friday morning as a surface low lifting into the northern Plains sends a warm front north through the area.
Storm chances continue into Friday, though higher instability looks to remain focused just west of our CWA Despite this, strong effective wind shear due to an approaching mid-level jet may support a few organized storms Friday afternoon/evening as activity spreads east.

Better instability shifts into the area on Saturday as a cold front stalls out somewhere just west of here. Storm chances will increase once again Saturday evening as an upper trough lifts toward the middle Mississippi Valley, potentially bringing another shot at some severe storms. A deepening surface low will lift toward the Great Lakes Region on Sunday, sending a cold front through the area Sunday night. Timing differences still remain with this feature, but favorable parameters once again could support severe weather if the timing of FROPA isn't too late. 72 hour QPF totals between Friday and Monday look to be rather hefty with the NBM indicating a 50-80% chance of 1.5 inches or more and a 20-50% chance of 2 inches or more (higher end chances west of I-55).

AVIATION
(For the 06z TAFs through 06z Tuesday Night)
Issued at 1146 PM CDT Mon Apr 22 2024

Latest CAMs continue to spread showers into KPIA by 11z...then further southeast to the I-72 terminals by around 14z. Main aviation forecast challenge will be the development of MVFR ceilings.
Strongest lift/deepest moisture appears to develop mostly north of I-72...with HRRR consistently dropping cloud bases to MVFR for a 4-6 hour period from mid-morning through early afternoon. As the showers drop southeast of the TAF sites, have raised ceilings back to low VFR at KPIA by 19z...then by 21z at KSPI/KDEC/KCMI. The surface cold front will pass through central Illinois by late afternoon/early evening, perhaps accompanied by additional scattered showers. Have therefore held on to VCSH until the boundary passes and skies clear after the 01z-04z time period.
Winds will initially be SW at 10-15kt, then will veer to NW and decrease to less than 10kt after FROPA Tuesday evening.
