⚠️ SEVERE WEATHER UPDATE ⚠️

🟡 The stage has been set for isolated to scattered thunderstorms to develop in eastern Iowa and western Illinois as we head into the evening hours. Although significant severe weather is no longer expected, storms will still be capable of producing damaging wind gusts, hail and possibly brief tornadoes.

PRIMARY THREATS
Gusts up to 60+ mph possible
Brief tornadoes possible
Quarter size hail possible

💨 BURST OF WIND: A ‘wake low’ is the cause of a sudden burst of strong wind felt in the immediate QCA Monday morning.

OBSERVED GUSTS
Moline 53 MPH
Dubuque 51 MPH
Davenport 49 MPH

❔A wake low is a small-scale, intense area of low pressure that forms 30 to 50 miles behind a line of decaying thunderstorms or a squall line, often causing high winds and clearing skies.

❔These systems create a sharp pressure difference, or gradient, between the trailing wake low and the preceding mesohigh, resulting in strong, damaging wind gusts as the air rushes toward the low-pressure center.

⚠️ SEVERE WEATHER UPDATE ⚠️

👉 Widespread rain, storms and cloud cover this morning will help subdue the overall threat for severe weather in the local QCA region. However, there may still be enough energy to spawn a few strong to severe storms later this afternoon into the evening before cold front moves eastward through the region.

👉 Meanwhile, further to our south, the threat for significant to intense severe storms remains intact, including the St. Louis Metro area, where destructive wind, large hail and tornadoes are possible later today into tonight.

⚠️ LEVEL 2 SEVERE WEATHER THREAT MONDAY INTO MONDAY NIGHT

🗓️ Monday April 27
⏰ 12:00pm - 10:00pm
📍 Greatest risk south of I-80
⚠️ All severe hazards possible

🟡 OVERALL THREAT: Level 2 of 5
🟠 PEAK POTENTIAL: Level 3 of 5

👉 A few strong to severe thunderstorms remain possible in the QCA region Monday afternoon into the evening, but the threat for significant severe weather has shifted well to our south.

🟨 LEVEL 2 THREAT: After uncertainty plagued the forecast for past several days, model guidance has come into alignment with observations showing morning rain, storms and cloud cover are stabilizing the atmosphere and will leave little time for recovery before cold front advances east into the QCA later today. Nonetheless, there is still expected to be a modest recovery, allowing additional storms to develop in the afternoon and early evening carrying risk for all severe hazards, as they advance east from Iowa into Illinois, including damaging wind gusts, hail and possibly a brief tornado before storms clear to our east by 10pm or sooner.

L2 PRIMARY THREATS
• Gusts up to 70 mph possible
• Tennis ball size hail possible
• Few tornadoes possible
• Flash flooding possible

🔘 CURRENT: LEVEL 2 • ELEVATED
📈 ODDS FOR UPGRADE: 25%
📉 ODDS FOR DOWNGRADE: 50%

Forecast is subject to change.

⚠️ LEVEL 3 SEVERE WEATHER THREAT MONDAY INTO MONDAY NIGHT

🗓️ Monday April 27
⏰ 12:00pm - 10:00pm
📍 Greatest risk south of I-80
⚠️ All severe hazards possible

🟠 OVERALL THREAT: Level 3 of 5
🔴 PEAK POTENTIAL: Level 4 of 5

👉 Multiple rounds of strong to severe thunderstorms are expected late Sunday night thru Monday with severe weather most likely to occur in the afternoon and evening when potentially significant to intense severe storms are anticipated, especially south of I-80, but the threat exists areawide.

🟧 LEVEL 3 THREAT: There remains considerable uncertainty regarding timing, placement and intensity of the strongest storms. Nonetheless, thunderstorms are likely areawide with all storms capable of becoming severe, some of which could be intense and capable of producing strong tornadoes and destructive wind and hail. Furthermore, storms will produce heavy rainfall leading to the potential for flash flooding in some areas. As of now, we generally expect showers and storms from late Sunday night, possibly persisting thru midday Monday, followed redeveloping storms later in the afternoon and evening advancing eastward into Illinois before clearing the QCA region to our east by around 10pm. Model guidance currently suggests the most favorable environment for significant severe weather could be mostly confined to areas south of the I-80 corridor. This is where an upgrade to Level 4 may be needed. However, there is still no overwhelming consensus, thus, we will maintain Level 3 areawide, but this is subject to change.

L3 PRIMARY THREATS
• EF2+ tornadoes possible
• Wind gusts up to 70+ mph
• Golf ball size hail possible
• Flash flooding possible

🔘 CURRENT: LEVEL 3 • MEDIUM
📈 ODDS FOR UPGRADE: 50%
📉 ODDS FOR DOWNGRADE: 50%

Forecast is subject to change.

Monday’s severe threat remains very uncertain north of I-80 but is on track for areas to the south, as of Sunday

04/24/2026

🟠 SEVERE WEATHER EXPECTED 🟠

🟧 MONDAY INTO MONDAY NIGHT:
A robust storm system traverses the region bringing another round of thunderstorms to the QCA with an increasing risk for all severe hazards, including damaging wind, large hail, tornadoes and flash flooding. The entire area will face threat of severe weather, but details such as precise timing, placement and intensity of the strongest storms will become more refined over the next 24 to 48 hours. As of now, model guidance suggests showers and storms may be ongoing Monday morning and could persist thru midday, which could sap energy needed for robust severe weather later in the afternoon and evening. Monitor the forecast closely and stay tuned in for more updates.
