Frederick Douglass/Greater Rochester International to Baltimore/Washington International Thurgood Marshall ROC → BWI

241 nautical miles (277 statute miles) south on a straight line, true course 169°, about 181° magnetic at the departure end (variation 12W). At 120 knots that is 2 h 02 min at the quickest height in today's winds (6,500 ft, a 1-knot headwind), arriving about 11:50 pm EDT (03:50 UTC), after sunset at the destination. Right now ROC is VFR, wind from the east-southeast (110°) at 5 knots; BWI is low IFR, wind from the northeast (050°) at 7 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: 2,184 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 2E: thunderstorms (a convective SIGMET) up to 31,000 ft, moving from the southwest at 20 knots, until 10:55 pm EDT (02:55 UTC). Over the route from 174 to 222 nm out.

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 2 forecast points nearest it (BUF, PSB). 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.
