As of mid-March 2026, around March 12) is based primarily on data from the National Weather Service (NWS) point forecast for the area around 42.5°N, 90.7°W, near Dubuque Regional Airport, cross-referenced with other sources like Weather Underground, AccuWeather, and The Weather Channel for consistency. Current conditions show fair/clear skies with temperatures in the upper 20s to low 30s °F, light winds, and high pressure influencing the short-term pattern.

Note: March in the Upper Midwest (like eastern Iowa) often features highly variable weather, with rapid swings between mild spells, wind events, and potential wintry mixes or rain/snow transitions due to frontal passages. Winds have been breezy to strong recently, with advisories noted in some reports. Forecasts can shift with new model runs, especially for precipitation type and timing.

Detailed 7-Day Forecast (Starting from Today, March 12, 2026)

Thursday, March 12 (Today)

•  High/Low: Around 46–48°F / 33–35°F

•  Conditions: Mix of sun and clouds early, becoming mostly cloudy in the afternoon. Breezy to windy, with southwest winds 15–25 mph (gusts possibly higher).

•  Precipitation: Low chance (under 10–20%); dry for most of the day, though a passing shower can’t be ruled out late.

•  Notes: Milder day with moderating temperatures. Wind will make it feel cooler than the actual reading, especially in exposed areas.

Friday, March 13

•  High/Low: Around 43–45°F / 26–30°F

•  Conditions: Partly to mostly cloudy; breezy or windy continuing (west-northwest winds 15–25 mph possible).

•  Precipitation: Slight chance of showers (10–30%), mainly light and scattered. Some sources hint at a few flurries mixing in if colder air arrives.

•  Notes: Cooler than today; a transitional day as a cold front approaches or passes.

Saturday, March 14

•  High/Low: Around 30–35°F / 15–20°F

•  Conditions: Mostly cloudy to overcast, turning colder with northwest winds.

•  Precipitation: Chance of scattered flurries or light snow showers (20–40% in some models). Accumulation minimal if any (under 1 inch).

•  Notes: Return to more seasonal March chill; wind chills could dip into the single digits or below zero overnight.

Sunday, March 15

•  High/Low: Around 35–40°F / 25–30°F (or lower in some outlooks)

•  Conditions: Cloudy with periods of precipitation possible.

•  Precipitation: Higher chance of rain (50–70%), possibly mixed with or changing to snow early/late depending on temperature profiles.

•  Notes: Potential for a more widespread wet period; check updates for rain vs. snow line, as Dubuque sits near typical transition zones in spring systems.

Monday, March 16

•  High/Low: Around 38–45°F / 25–32°F

•  Conditions: Partly cloudy to mostly cloudy; winds shifting and possibly lighter.

•  Precipitation: Chance of lingering showers (20–40%), tapering off.

•  Notes: Gradual drying trend; temperatures rebound slightly but remain below average for mid-March.

Tuesday, March 17

•  High/Low: Around 42–48°F / 28–35°F

•  Conditions: Mix of sun and clouds; milder again with southwest flow possible.

•  Precipitation: Low chance (under 20%); mostly dry.

•  Notes: Potential brief warming before the next system; typical pattern of alternating ridges and troughs.

Wednesday, March 18

•  High/Low: Around 45–50°F / 30–35°F (preliminary)

•  Conditions: Partly cloudy to mostly sunny if high pressure builds.

•  Precipitation: Low chance; dry day favored in longer-range guidance.

•  Notes: End of the period shows signs of more stable, seasonal conditions, though another front could approach by late week.

Overall Patterns and Considerations

•  Temperature Trends: Starting mild (mid-40s) today, cooling sharply over the weekend into early next week (highs in the 30s), then modest recovery mid-week. Nighttime lows frequently in the 20s–30s, with frost/freeze risk possible (typical for March in Iowa).

•  Precipitation: Sporadic chances through the period, with the highest odds over the weekend into early next week (rain/snow mix possible). Accumulations generally light unless a stronger low-pressure system develops.

•  Winds: Breezy to windy at times (especially today/Friday), with gusts 25–40+ mph possible in advisories. This amplifies the chill factor.

•  Edge Cases: If a stronger cold front dives south, more significant snow could occur Saturday–Sunday (unlikely based on current consensus). Conversely, if warmer air surges north, rain dominates instead of any frozen precip.
