St. Louis – A stunning Easter Sunday bathed the region in crystal clear skies, providing perfect conditions for holiday gatherings and outdoor activities. Monday followed suit with gorgeous sunny skies and highs reaching the low to mid-60s, offering a pleasant start to the workweek.[1][2] Clouds began building Monday evening, however, signaling a rapid shift to cooler temperatures overnight into the upper 30s.

Easter Sunday Delivered Ideal Conditions

The holiday weekend kicked off memorably across the St. Louis area. Clear blue skies dominated Easter Sunday, April 5, allowing families to celebrate without a drop of rain or gusty winds. Such weather stood out in early April, when spring patterns often bring variability.

This backdrop made the transition to Monday feel seamless. Residents took advantage of the mild warmth for walks, errands, and park visits before clouds encroached later in the day.

Monday’s Sunny Respite Proves Short-Lived

Sunshine ruled Monday, with northwest winds at 10 to 15 mph and gusts up to 25 mph keeping the air crisp yet comfortable. Highs settled in the lower 60s for most spots, according to the National Weather Service.[2] The pleasant conditions encouraged outdoor lunches and light jackets rather than heavy coats.

By evening, the influx of clouds marked the end of the sunny stretch. Temperatures plunged quickly after sunset, setting the stage for a frosty night. This change reflects a classic Midwest pattern where warm fronts yield to cooler air masses.

Overnight Chill Brings Snow Risk to the North

A band of snow and rain-snow mix targeted areas north of St. Louis overnight into Tuesday morning. The system primarily affected northeast Missouri and west-central Illinois, with potential snowflakes reaching northern Pike County in Missouri and northern Greene, Macoupin, and Montgomery counties in Illinois.[1] St. Louis itself faced mostly cloudy skies and lows in the upper 30s, but no significant wintry precipitation.

Warm ground temperatures prevented any accumulation, even in the northern zones. Travel impacts remained minimal, though drivers in those counties prepared for slick spots on bridges or untreated roads. Meteorologists emphasized monitoring updates as the system evolved.

Midweek Warm-Up Ahead of Rainy Patterns

Tuesday brought cloudier conditions with highs only in the mid-50s under east winds around 10 mph. The cooler air lingered briefly before a warmup on Wednesday, where partly sunny skies pushed temperatures into the lower 70s.[2]

The forecast turned unsettled later in the week. Here is a snapshot of expected highs and precipitation chances:

Day	High (°F)	Precip Chance
Tuesday	Mid 50s	Low
Wednesday	Lower 70s	0%
Thursday	Lower 70s	40%
Friday	Lower 70s	60%

South winds strengthened midweek, fueling the return of spring-like warmth. Showers and thunderstorms became likely Thursday through the weekend, with highs climbing toward the upper 70s and low 80s by Sunday.

Monday: Sunny, highs low-mid 60s; clearing to cloudy overnight, lows upper 30s.
Tuesday: Partly sunny after morning clouds, mid-50s.
Wednesday-Thursday: Warming trend with scattered shower risks.
Friday-Sunday: Multiple rain chances amid 70s-80s highs.

Key Takeaways
No snow accumulation expected anywhere in the St. Louis metro due to warm ground.
Quick rebound to 70s by Wednesday offers relief from the chill.
Prepare for wet conditions late week with possible thunderstorms.

St. Louis weather exemplifies spring’s unpredictability, swinging from holiday perfection to a wintry whisper before embracing warmer days. Residents should bundle up tonight but look forward to milder air soon. What are your plans if the sun sticks around midweek? Tell us in the comments.
