Yellowstone Regional to Reno/Tahoe International COD → RNO
566 nautical miles (651 statute miles) southwest on a straight line, true course 242°, about 231° magnetic at the departure end (variation 11E). At 120 knots that is 5 h 01 min at the quickest height in today's winds (8,500 ft, a 7-knot headwind), arriving about 5:43 am PDT (12:43 UTC), after sunset at the destination. Right now COD is low IFR, wind from the north-northeast (030°) at 8 knots; RNO is VFR, wind from the north-northeast (030°) at 9 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: 1 flights in the DOT's last twelve reported months, the route's page.

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 SIERRA 4E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist), from 12:00 am MDT (06:00 UTC). Over the first 79 nm of the route.
- AIRMET ZULU 2C: moderate icing up to 23,000 ft, from 12:00 am MDT (06:00 UTC). Over the first 407 nm of the route.
- AIRMET TANGO 4W: moderate turbulence below 18,000 ft up to 18,000 ft, from 12:00 am MDT (06:00 UTC). Over the first 0 nm of the route.
- AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist), from 12:00 am MDT (06:00 UTC). Over the first 367 nm of the route.
- AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 36,000 ft, from 12:00 am MDT (06:00 UTC). Over the route from 268 to 347 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 COD.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
No pilot reports within 50 nautical miles of the line in the last three hours.

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 4 forecast points nearest it (LND, PIH, BAM, RNO). 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 COD 6:35 pm MDT (00:35 UTC), at RNO 6:23 pm PDT (01:23 UTC) (civil twilight ends 6:50 pm PDT (01:50 UTC)). At 120 knots the arrival at RNO is before sunrise there (7:05 am PDT (14:05 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.
