Pullman/Moscow Regional to Boise Air Trml/Gowen Field PUW → BOI
194 nautical miles (224 statute miles) south on a straight line, true course 169°, about 154° magnetic at the departure end (variation 15E). At 120 knots that is 1 h 30 min at the quickest height in today's winds (5,500 ft, a 10-knot tailwind), arriving about 9:26 pm MDT (03:26 UTC), after sunset at the destination. Right now PUW is VFR, wind from the north (010°) at 8 knots; BOI is VFR, wind from the east-southeast (120°) 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: 386 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 ZULU 2C: moderate icing up to 16,000 ft. Over the first 97 nm of the route.
- AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the first 136 nm of the route.
- AIRMET TANGO 4W: moderate turbulence above 18,000 ft from 18,000 ft to 36,000 ft. Over the last 39 nm of the route.
- AIRMET ZULU 3C: moderate icing up to 22,000 ft. Over the last 19 nm of the route.
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 PUW.

Based on data from the 11th at 18:00 UTC; valid on the 12th at 00:00 UTC for use 20:00 to 03:00 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.
