Wednesday, March 25, 2026 – Dubuque, Iowa

Residents of Dubuque and the surrounding Tri-State area are enjoying a pleasant midweek warm-up today as spring-like conditions settle in briefly before a notable temperature drop and potential showers arrive later in the week. With the Mississippi River bluffs still showing hints of winter and early buds beginning to appear, the forecast highlights a classic March pattern: fluctuating temperatures, shifting winds, and variable cloud cover typical for this transitional season in eastern Iowa.

Today’s Outlook (Wednesday, March 25)

Expect mostly sunny skies with a high near 71°F (some sources suggest up to 73°F). South winds at 5–10 mph, with gusts possible to 20 mph, will keep conditions comfortable and aid in any outdoor activities.  

Tonight, skies become partly cloudy with a low around 51°F. Winds shift southwest and lighten to around 5 mph, becoming calm later. No significant precipitation is expected, making for a mild evening. 

Nuances and implications: Today’s warmth feels especially inviting after recent cooler days, with daytime highs well above the March average (typically in the mid-40s to low 50s). UV indices will be moderate (around 4–5), so light sun protection is advisable for extended time outdoors. Air quality remains generally fair based on recent observations.

Thursday (March 26)

A partly sunny start gives way to increasing clouds, with a 40% chance of showers developing after 1 p.m. High temperatures reach the upper 60s to low 70s (around 68–69°F). Winds become northerly at 10–15 mph with gusts up to 25 mph by afternoon, introducing a breezier feel.  

Thursday night turns mostly cloudy with a low dropping sharply to around 30–31°F. Northerly winds persist at 10–15 mph with similar gusts. Any lingering showers taper off early evening.

Edge cases and considerations: The shower chance is isolated rather than widespread, but breezy conditions could make it feel cooler than the actual temperature, especially near the river. Those sensitive to rapid temperature swings may notice the contrast from daytime warmth.

Friday (March 27)

Much cooler conditions arrive with mostly sunny skies and a high only in the mid-40s (around 46°F). Winds remain light to moderate from the north or northwest. Clear skies overnight bring a low near 26°F, with frost possible in sheltered areas. 

Implications: This represents a roughly 20–25°F drop from Thursday’s high, a sharp reminder of March’s volatility. Gardeners and farmers should monitor tender plants, as overnight lows dip below freezing. Outdoor recreation like hiking along the bluffs or riverfront trails will require layers and wind-resistant clothing.

Saturday (March 28)

Sunny skies dominate with a high climbing back to the low-to-mid 50s (around 52–54°F). Winds ease somewhat. Overnight, partly cloudy conditions prevail with a low near 38°F. 

Sunday (March 29)

Mostly sunny to partly cloudy with continued moderation; highs reach the low 60s (around 62°F). Lows overnight stay in the mid-40s (around 43–47°F), with increasing cloudiness possible by late evening. 

Extended Look Ahead (Monday–Tuesday, March 30–31)

•  Monday: Mostly sunny with highs pushing into the low-to-mid 70s (near 74°F), offering another pleasant day. A 40% chance of rain develops Monday night with lows around 52°F. 

•  Tuesday: Partly sunny with a 30% chance of rain and highs near 71°F.

Overall Patterns, Context, and Related Considerations

This week’s forecast captures March’s hallmark unpredictability in the Upper Midwest. A brief ridge of high pressure brings today’s warmth and Thursday’s mild start, but a strong cold front passage late Thursday introduces the cooler air mass that lingers into Friday. By the weekend, high pressure rebuilds, allowing gradual recovery.

Precipitation totals: Expect minimal accumulation overall—perhaps a few hundredths of an inch from Thursday’s isolated showers—with drier conditions dominating the weekend. Snow is not anticipated, though frost remains a concern Friday night.

Wind and visibility: Gusty northerlies Thursday could affect driving or boating on the Mississippi, while clearer skies later in the week improve visibility for aviation and outdoor events.

Longer-term nuances: Historical March data for Dubuque shows average highs around 46–50°F with frequent temperature swings and about 6–10 days of measurable precipitation. This week’s pattern aligns with that, including above-average warmth mid-week followed by a correction.

Practical advice:

•  Today–Thursday: Ideal for spring cleaning, yard work, or enjoying Dubuque’s parks and trails while layering for the evening cooldown.

•  Friday–Saturday: Bundle up for colder mornings; check frost advisories if applicable.

•  Weekend: Great for outdoor festivals, farmers’ markets, or riverfront strolls as temperatures moderate.

•  Always verify updates closer to the day, as short-term changes in shower timing or wind strength can occur. Local sources like the National Weather Service Quad Cities office or Dubuque Regional Airport observations provide the most precise real-time data.

Stay tuned for any hazardous weather outlooks, particularly regarding strong winds Thursday or potential frost. Dubuque’s location along the river can sometimes amplify temperature contrasts and fog risks during transitions, though none are highlighted for the immediate period.

Enjoy the mild interlude while it lasts—spring is indeed on its way, even if it arrives in fits and starts! For hourly details or radar, check trusted local resources.
