Falls Intl/Einarson Field to Marquette Sawyer Regional INL → SAW
278 nautical miles (320 statute miles) southeast on a straight line, true course 116°, about 113° magnetic at the departure end (variation 3E). At 120 knots that is 1 h 35 min at the quickest height in today's winds (34,000 ft, a 55-knot tailwind), arriving about 12:13 am EDT (04:13 UTC), after sunset at the destination. Right now INL is VFR, wind from the east (080°) at 9 knots; SAW is low IFR, wind from the northeast (040°) at 8 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
- SIGMET 3C: thunderstorms (a convective SIGMET) up to 45,000 ft, moving from the southwest at 35 knots, until 10:55 pm CDT (03:55 UTC). Over the last 268 nm of the route.

Turbulence No turbulence warning in force along the route. A pilot reported smooth air, at 36,000 ft, 15 nm southwest, 6:56 pm CDT (23:56 UTC). The government's turbulence forecast map ↗
Icing AIRMET in force: moderate icing up to 22,000 ft, over the first 10 nm of the route. No pilot has reported icing near the line in the last three hours. The freezing level is about 13,500 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 INL.

Based on data from the 13th at 00:00 UTC; valid on the 13th 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.

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.
