MC Allen International to Reno/Tahoe International MFE → RNO

1,343 nautical miles (1,545 statute miles) northwest on a straight line, true course 312°, about 308° magnetic at the departure end (variation 4E). At 120 knots that is 10 h 50 min at the quickest height in today's winds (10,500 ft, a 4-knot tailwind), arriving about 5:52 pm PDT (00:52 UTC). Right now MFE is VFR, wind from the southeast (130°) at 8 knots; RNO is VFR, wind from the north (360°) 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: 7 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 W28W: thunderstorms (a convective SIGMET) up to 30,000 ft, moving from the south at 35 knots, until 10:55 am CDT (15:55 UTC). Over the route from 1084 to 1104 nm out.

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 11 forecast points nearest it (BRO, LRD, DRT, MRF, ELP, ABQ, PHX, PRC, LAS, BIH, RNO). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 06:00 UTC; valid on the 12th 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.
