Game Day Weather: Impact Field, Rosemont, ILChicago Dogs vs. Winnipeg Goldeyes — Sunday, July 5, 2026 | First Pitch 3:00 PM CDTA complete meteorological breakdown of weather conditions for today's game.=== THE STADIUM ===Impact Field | 9850 Balmoral Ave, Rosemont, IL 60018Coordinates: 41.983°N, 87.874°W | ~12 miles NW of downtown Chicago=== WEATHER SUMMARY ===NWS Chicago AFD issued 12:23 PM CDT, forecaster Yack.Pattern: Baggy shortwave trough over western Great Lakes. Broad surface low over southern Lake Michigan. Very saturated low levels — dew points near 68°F (tropical threshold). IFR fog and low stratus through midday.KEY FINDING FOR ROSEMONT: Primary storm axis is near/south of the Kankakee River Valley (30-40% chance), and as a precaution north to I-80 (20-25%). Rosemont sits 20+ miles north of I-80 — in the favored DRY zone.At First Pitch (3 PM CDT):- Temperature: ~75-78°F- Dew Point: ~68°F (humid but comfortable with lake breeze)- Sky: Mostly cloudy- Wind: NNE 10-15 mph gusts to 20 mph- Precipitation Probability (Rosemont): ~20%- Severe Threat: Virtually ZERO (limited wind shear, weak instability)=== NWS TERMS EXPLAINED IN THIS EPISODE ===- Baggy shortwave trough: Diffuse, spread-out dip in the jet stream — not a focused punch- Shortwave trough: Small-scale dip in the jet stream driving rising air and weather- Surface low: Low pressure at ground level drawing air inward and upward- Very saturated low levels: Air near the surface is soaked with moisture (dew point 68°F)- Wind shear: How wind speed/direction changes with altitude — limited today = brief pulse storms only- Instability: Atmospheric fuel for thunderstorm updrafts — much weaker than heat dome days- GFS, NAM, HREF, NBM: Weather models used to generate forecast guidance- Ensemble spread: Range of solutions across multiple model runs=== IMPACT FIELD DRAINAGE — THE SECRET WEAPON ===Built in 2018 with one of the best drainage systems in minor league baseball.Can absorb 1 inch of rain (64,000 gallons) and return to playable condition in 20-25 minutes.Source: Daily Herald, 2017 pre-opening report.=== RAIN-OUT CRITERIA (American Association / Impact Field) ===Per Chicago Dogs official policy: Games will NOT be postponed before start time except in extreme circumstances.American Association umpires determine delays/postponements once game begins.Actual stoppage triggers: Standing water ≥1/4 inch in batter's box/pitcher's rubber zone, field saturation preventing cleat grip, visibility below 500 feet, OR lightning within 8 miles.Official game: 5 innings completed (4.5 if home team leads).No game: Fewer than 5 innings, cannot resume — must be replayed.=== VERDICT ===Rain-out probability at Impact Field: LOW.- Rosemont is 20+ miles north of the primary storm zone- Severe threat: Virtually zero- ~20% POP in the NWS hourly forecast (8 in 10 scenarios = no rain during game)- If a brief shower does clip the stadium, drainage allows resumption in ~25 min- Lightning within 8 miles is the most likely cause of any delay — and the storm track argues against itRECOMMENDATION: Go to the game. Bring a light rain jacket. Bring sunscreen. Wear comfortable shoes.=== SOURCES ===- NWS Chicago AFD: https://forecast.weather.gov/product.php?site=LOT&issuedby=LOT&product=AFD- NWS Hourly Forecast (Rosemont): https://forecast.weather.gov/MapClick.php?CityName=Rosemont&state=IL&site=LOT&textField1=41.9836&textField2=-87.8742&FcstType=digital- Chicago Dogs Rain Policy: https://thechicagodogs.com/explore-impact/policies/- Impact Field Drainage: Daily Herald, September 2017- CBS Chicago morning forecast: https://www.cbsnews.com/chicago/news/chicago-weather-first-alert-weather/Tags: weather, Chicago Dogs, Impact Field, Rosemont, game day forecast, rain delay, baseball weather, NWS ChicagoBecome a supporter of this podcast: https://www.spreaker.com/podcast/weather-with-enthusiasm--4911017/support.Weather with Enthusiasm is produced by Kol Simcha Productions.New episodes drop daily (B'N)— a morning forecast at 7 AM and historical deep dives Tuesdays and Thursdays.
