Boise Air Trml/Gowen Field to Denver International BOI → DEN
563 nautical miles (648 statute miles) east on a straight line, true course 109°, about 096° magnetic at the departure end (variation 13E). At 120 knots that is 4 h 24 min at the quickest height in today's winds (39,000 ft, a 8-knot tailwind), arriving about 7:46 am MDT (13:46 UTC). Right now BOI is VFR, wind from the west-northwest (290°) at 10 knots; DEN is marginal VFR, wind from the north-northwest (340°) at 6 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: 6,118 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 TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft. Over the first 217 nm of the route.
- AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 20 to 543 nm out.
- AIRMET ZULU 1C: moderate icing up to 22,000 ft. Over the route from 59 to 513 nm out.
- AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 24,000 ft to 36,000 ft. Over the route from 286 to 513 nm out.
- AIRMET TANGO 2W: moderate turbulence below 18,000 ft (due to mountain wave) up to 22,000 ft. Over the route from 336 to 523 nm out.
- AIRMET SIERRA 2E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the route from 425 to 484 nm out.
- AIRMET TANGO 1W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Near the route, at the destination end.
Turbulence AIRMET in force: moderate turbulence from 18,000 ft to 39,000 ft, over the first 217 nm of the route; AIRMET in force: moderate turbulence from 24,000 ft to 36,000 ft, over the route from 286 to 513 nm out. AIRMET in force: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground), near the route, at the destination end. 3 pilot reports of turbulence near the line in the last three hours: moderate turbulence from 23,000 ft to 26,000 ft, 31 nm south, 12:48 am MDT (06:48 UTC); moderate turbulence, at 20,000 ft, 40 nm southwest, 1:15 am MDT (07:15 UTC). The government's turbulence forecast map ↗
Icing AIRMET in force: moderate icing up to 22,000 ft, over the route from 59 to 513 nm out. No pilot has reported icing near the line in the last three hours. The freezing level is about 10,000 ft (from the winds-aloft temperatures), so icing is possible in cloud above that. The government's icing forecast map ↗
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 BOI.

Winds aloft along the route, and the time en route the forecast for use 08:00–15:00 UTC · at 120 knots true airspeed
The eastbound cruising heights for this course (VFR: odd 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 (BOI, PIH, RKS, DEN). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 13th at 06:00 UTC; valid on the 13th at 12:00 UTC for use 08:00 to 15:00 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.

From the FAA's notice service (NOTAMs), the site's copy refreshed every few minutes; last checked a minute ago. The FAA has so far issued eFlight its test feed, which misses some notices (checked against the FAA's own search on 12 October: about a third missing at Santa Barbara and Burbank, none at Atlanta or Las Vegas); the request for the full feed is with the FAA. Times are local to the field. This is for planning; the legal briefing comes from Flight Service or the FAA's own tools.
Daylight
Sunset at BOI 7:03 pm MDT (01:03 UTC), at DEN 6:21 pm MDT (00:21 UTC) (civil twilight ends 6:48 pm MDT (00:48 UTC)).
Each restriction opens the FAA's own page with the exact area, heights and times.
The wind over the route live wind map, from Windy.com · drag the time bar for the coming hours; the level menu changes the height
Colours show wind speed, the moving lines its direction, at the surface unless you pick a height. Map and forecast by Windy.com; a second opinion beside the government's winds-aloft table above.
Radar and forecast charts for the regions crossed government pictures, the latest each time the page loads · the turbulence and icing forecasts: turbulence ↗ · icing ↗
Sources: the Aviation Weather Center's data service (SIGMETs, AIRMETs, graphical AIRMETs, pilot reports, winds and temperatures aloft, observations and terminal forecasts), the National Weather Service radar, the Weather Prediction Center's charts, the FAA's temporary flight restriction list and shapes, and the FAA's airport file for the positions, elevations and magnetic variation. Fetched when the page is viewed and kept a few minutes. Each leg is the straight line between its two airports; airways, terrain and airspace are not considered.
