Chicago Midway International to Rocky Mountain Metro Airport MDW → BJC

795 nautical miles (915 statute miles) west on a straight line, true course 268°, about 272° magnetic at the departure end (variation 4W). At 120 knots that is 8 h 02 min at the quickest height in today's winds (4,500 ft, a 21-knot headwind), arriving about 12:44 pm MDT (18:44 UTC). Right now MDW is VFR, wind from the south-southwest (210°) at 6 knots; BJC is marginal VFR, wind from the north-northwest (340°) at 5 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 C29C: thunderstorms (a convective SIGMET) up to 34,000 ft, moving from the southwest at 35 knots, until 6:55 am CDT (11:55 UTC). Over the route from 229 to 338 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), from 4:00 am CDT (09:00 UTC). Over the first 149 nm of the route.
AIRMET SIERRA 9E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist), from 4:00 am CDT (09:00 UTC). Over the route from 547 to 746 nm out.
AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist), from 4:00 am CDT (09:00 UTC). Over the last 10 nm of the route.
AIRMET TANGO 2W: moderate turbulence below 18,000 ft (due to mountain wave) up to 22,000 ft, from 4:00 am CDT (09:00 UTC). Near the route, at the destination end.

Turbulence AIRMET in force: moderate turbulence (due to mountain wave) up to 22,000 ft, near the route, at the destination end. 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), over the first 149 nm of the route. 1 pilot report of turbulence near the line in the last three hours: light chop turbulence up to 23,000 ft, 10 nm west, 4:12 am CDT (09:12 UTC). The government's turbulence forecast map ↗

Icing No icing warning in force along the route. No pilot has reported icing near the line in the last three hours. The freezing level is about 14,000 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 MDW.

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 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 8 forecast points nearest it (JOT, DBQ, BRL, DSM, OMA, GRI, GLD, 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 2 minutes 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.
