It is possible that this page will report a problem where no problem exists.

The elevation does not correspond with the estimated elevation (2 metres (7 feet) -- source NED 1/9th arc-second: Louisiana) at that point. It seems probable that the elevation was entered as feet rather than as metres. Please use the 'send the updated information' link below to update the location or elevation.
The site location should be at the mark shown -- or very close. Clicking within the map area (or you can drag the 'KXPY' marker) will display the latitude/longitude of that point.
If the displayed location (or elevation) of the weather observing location is incorrect, please drag the marker to the right location (or click in the right location), and then send the updated information. Please note that we are trying to spot either the Stevenson Screen (or equivalent) or the location where the barometric readings are taken.
Can you help with location quality? Please indicate if the marker on the map points at the weather instrument cluster:
The best way to get elevation is to consult a topographic map. Make sure that you know whether the contours are marked in feet or metres. Note that handheld GPS receivers do not provide readings of elevation accurate to better than 10-20 metres (technical discussion). If you do not have access to a topographic map, then a GPS receiver is acceptable, but make sure that it is operating in 3D mode and let it average the position for at least five minutes.
For more information on reading maps, please see the Topo Map Reading Guide -- in particular it discusses how to read contours.
The location information for this site was gathered from 9 data sources. The source which most closely matches the consensus is chosen. Many of these sources only report the location to the nearest minute (or hundredth of degree). This can lead to the marker being placed noticeably incorrectly. Please see Discussion of Location Errors for more information. Show location history.

Recent observations from this weather station can be downloaded as a CSV file suitable for importing into various spreadsheet programs: last 7 days, last 14 days, last 28 days, last 56 days. This data can also be linked directly from Excel using a Web Query. The main link goes to the page with the data on it, and the IQY link is the Web Query that will access it: last 7 days (IQY: last 7 days), last 14 days (IQY: last 14 days), last 28 days (IQY: last 28 days), last 56 days (IQY: last 56 days).
All the means and standard deviations shown below are from the last 28 days. Change analysis period to Last 3 days Last 7 days Last 14 days Last 8 weeks Last 13 weeks Last 26 weeks Last 39 weeks Last 52 weeks
The inconsistency noted above in your location information means that the analyzed readings for your location may be incorrect. For example, if your location is incorrect, then the analysis values will be for a location other than your station. This will give different analysis results, probably leading to errors being shown below. If the elevation is incorrect, then the comparison of temperature readings will be in error.

|The wind vector is the average wind over the relevant period. Note that if the wind blows North for half the time at 2 knots, and then blows South for the other half of the time at 2 knots, then the result is zero -- i.e. North wind and South wind will cancel out.|
