Portland International to Pocatello Regional PDX → PIH

459 nautical miles (528 statute miles) east on a straight line, true course 107°, about 091° magnetic at the departure end (variation 16E). At 120 knots that is 3 h 15 min at the quickest height in today's winds (39,000 ft, a 21-knot tailwind), arriving about 10:50 pm MDT (04:50 UTC), after sunset at the destination. Right now PDX is VFR, wind from the east-southeast (110°) at 4 knots; PIH is VFR, wind from the southwest (230°) 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 ZULU 2C: moderate icing up to 14,000 ft, from 5:00 pm PDT (00:00 UTC). Over the route from 70 to 209 nm out.
AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist), from 5:00 pm PDT (00:00 UTC). Over the last 349 nm of the route.
AIRMET TANGO 4W: moderate turbulence above 18,000 ft from 18,000 ft to 36,000 ft, from 5:00 pm PDT (00:00 UTC). Over the last 199 nm of the route.
AIRMET ZULU 3C: moderate icing up to 22,000 ft, from 5:00 pm PDT (00:00 UTC). Over the last 150 nm of the route.
AIRMET SIERRA 4E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist), from 5:00 pm PDT (00:00 UTC). Over the last 120 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 PDX.

Winds aloft along the route, and the time en route the forecast for use 20:00–03:00 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 (PDX, RDM, BOI, PIH). A plus sign is a headwind, a minus sign a tailwind.

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.
