Duluth International to Laguardia Airport DLH → LGA

871 nautical miles (1,002 statute miles) east on a straight line, true course 108°, about 109° magnetic at the departure end (variation 1W). At 120 knots that is 4 h 50 min at the quickest height in today's winds (39,000 ft, a 60-knot tailwind), arriving about 3:51 pm EDT (19:51 UTC). Right now DLH is low IFR, wind from the east-northeast (070°) at 16 knots, gusting to 25; LGA is VFR, wind from the north-northwest (340°) at 13 knots, gusting to 20. 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.

The route the straight line, the warnings crossed, restrictions, pilot reports and the airports along the way · click a mark for its words

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 SIERRA 4E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the first 158 nm of the route.
AIRMET ZULU 3C: moderate icing from 12,000 ft to 24,000 ft. Near the route, 188 nm along the route.
AIRMET SIERRA 1E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, mist). Over the route from 603 to 762 nm out.
AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, mist). Over the route from 663 to 791 nm out.
AIRMET TANGO 3W: moderate turbulence above 18,000 ft from 24,000 ft to 40,000 ft. Over the last 20 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 DLH.

Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first

Winds aloft along the route, and the time en route the forecast for use 14:00–21:00 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 6 forecast points nearest it (DLH, GRB, TVC, BUF, AVP, JFK). 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.
