Okc Will Rogers International to Joplin Regional OKC → JLN
184 nautical miles (211 statute miles) northeast on a straight line, true course 054°, about 050° magnetic at the departure end (variation 4E). At 120 knots that is 1 h 04 min at the quickest height in today's winds (30,000 ft, a 52-knot tailwind), arriving about 11:57 am CDT (16:57 UTC). Right now OKC is VFR, wind from the south (190°) at 16 knots, gusting to 27; JLN is VFR, wind from the south-southwest (210°) at 17 knots, gusting to 28. 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 TANGO 2W: 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 last 39 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 OKC.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- urgent C182 , 0 nm north, 10:17 am CDT (15:17 UTC): remarks: low-level wind shear a 10-knot loss of airspeed from the surface to 800 ft during the descent runway 18 jln. At the destination end, 0 nm north of the line.

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 2 forecast points nearest it (OKC, TUL). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 12:00 UTC; valid on the 12th at 18:00 UTC for use 14:00 to 21:00 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.
