The course is derived from the runway designator (number × 10), not from a survey - the actual magnetic bearing can differ by a few degrees.
Declared distances (TORA, TODA, ASDA, LDA) are published in the national AIP - they are not part of this table.
What the METAR reports from KTRI for 2023-2025 show - counted hour by hour.
We computed these statistics from 26,299 METAR reports issued by KTRI in 2023-2025. VFR conditions prevailed 84% of the time, MVFR 10% and IFR or LIFR 6%. Best month for VFR flying: April (90% of hours VFR). Most IFR and LIFR hours: January (12%).
Through the day, IFR or LIFR conditions are most frequent around 12:00 UTC (15% of reports at that hour) and least frequent around 01:00 UTC (2%).
Fog (FG) was reported on 38 days a year on average, most often in January. Thunderstorms (TS) occurred on 43 days a year on average, and snowfall on 17.
The wind most often blows from W (270°) - 8% of reports. Calm (0 kt) made up 46% of reports, and gusts of 25 kt or more appeared in 2%. Warmest month: July (average high 30.9 °C); coldest: January (average low -1.9 °C).
Day counts are for the selected period (for all years - the yearly average).
The top of each bar is the average daily high, the bottom the average daily low (usually around dawn), in °C.
Most often: W - 8% of reports. Each petal shows the direction the wind blows from (as in METAR) - the longer it is, the more often. Colour shows wind speed.

According to OurAirports data (compiled from AIP and FAA sources), Tri-Cities Regional TN/VA Airport (Blountville) has 2 runways: 05/23 - 2,438 m long (8,000 ft), 46 m wide, asphalt surface; 09/27 - 1,354 m long (4,443 ft), 46 m wide, asphalt surface.
The longest of them is 05/23, at 2,438 m.
The thresholds are oriented as follows: 05/23 on 50° and 230° magnetic, 09/27 on 90° and 270° magnetic. A threshold designator is its magnetic heading divided by ten (ICAO Annex 14), so the runway axis can be read straight off the numbers.
For the 05/23 axis, wind from the south-east (around 140°) or from the north-west (around 320°) blows perpendicular to the runway and produces the largest crosswind component. Wind from around 50° or 230° acts along the runway, as a headwind or a tailwind. The decoder on this page computes those components automatically from the current METAR.
Weather reports for Tri-Cities Regional TN/VA Airport (Blountville) are published under the ICAO code KTRI. A METAR is an observation of current conditions, usually issued every 30 or 60 minutes; a TAF is a forecast for the airport area, typically covering 9 to 30 hours.
The decoder breaks the KTRI report down into its parts: wind direction and speed including gusts and variability, visibility (including CAVOK and directional minimum visibility), weather phenomena by WMO code, cloud layers with their bases, temperature and dew point, QNH pressure, and the resulting flight category - VFR, MVFR, IFR or LIFR - using FAA thresholds.
Not every airport issues its own reports; many smaller airfields have no weather station. If no current data is available for KTRI, check the nearby airports listed below.
Reports always use UTC (the Z suffix). The America/New_York zone is GMT-05:00 in winter and GMT-04:00 in summer - that is the shift to apply to the time in the report to get local time at the airport.
The closest airports in the database, measured in a straight line from the reference point, are Virginia Highlands Airport (Abingdon) (KVJI, 41 km), Hawkins County Airport (Surgoinsville) (KRVN, 43 km), Greeneville Municipal Airport (KGCY, 48 km). When no report is available for KTRI, they usually give the best approximation of conditions in the area.
