Chicago/Rockford International to Joe Foss Field RFD → FSD
346 nautical miles (399 statute miles) west on a straight line, true course 286°, about 289° magnetic at the departure end (variation 3W). At 120 knots that is 3 h 16 min at the quickest height in today's winds (10,500 ft, a 14-knot headwind), arriving about 1:25 am CDT (06:25 UTC), after sunset at the destination. Right now RFD is VFR, wind from the southeast (140°) at 4 knots; FSD is VFR, wind from the northwest (320°) at 4 knots. For planning, not a briefing: the legal preflight briefing comes from Flight Service (1-800-WX-BRIEF) or the FAA's own tools. Airlines fly this pair: 3 flights in the DOT's last twelve reported months, the route's page.
The route the straight line, the warnings crossed, restrictions, pilot reports and the airports along the way · click a mark for its words
Green, blue, red and purple airport dots are the flying conditions reported there now (VFR, marginal VFR, IFR, low IFR); grey means no report. Red areas are SIGMETs, orange areas AIRMETs, hatched red areas temporary flight restrictions. Map tiles: OpenFreeMap, data © OpenStreetMap contributors.
Warnings the route crosses SIGMETs and AIRMETs whose area the line passes through or comes within 25 nm of
- AIRMET TANGO 3W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Over the route from 188 to 237 nm out.
A SIGMET warns of weather hazardous to all aircraft; an AIRMET of weather that matters to small aircraft and to flying without instruments. "From 60 to 180 nm out" is measured along the route from RFD.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- A321 at 32,000 ft, 19 nm southwest, 8:56 pm CDT (01:56 UTC): light turbulence, remarks: pocket continuous light turbulence. At the departure end, 19 nm southwest of the line.

Winds aloft along the route, and the time en route the forecast for use 02:00–09:00 UTC · at 120 knots true airspeed
The westbound cruising heights for this course (VFR: even thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 3 forecast points nearest it (DBQ, MCW, FSD). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 00:00 UTC; valid on the 12th at 06:00 UTC for use 02:00 to 09:00 UTC; temperatures above 24,000 ft are below zero. Heights are above sea level; a height is left out when the forecast has no wind for it over most of the line (the ground is higher). Ground speed is the airspeed less the headwind; the time en route is for the straight line and ignores climb, descent and routing around weather.

Daylight
Sunset at RFD 6:19 pm CDT (23:19 UTC), at FSD 6:49 pm CDT (23:49 UTC) (civil twilight ends 7:17 pm CDT (00:17 UTC)). At 120 knots the arrival at FSD is before sunrise there (7:37 am CDT (12:37 UTC)).
Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (closed runways, lights out) are not shown: the FAA's notice search is not open to sites like this one at this time.
