Board update
Effective April 12, 2021, we had to delete about 8000 frivolous spammer accounts going back over a year. There was no way for us to locate all legitimate user applications, so some may have been deleted. If you are an actual user who created an account since March 2020 but did not get approved, please register again. You can also contact us via the Contact link on the main Weather Graphics webpage to get assistance. When you contact us, it is essential you provide brief but detailed info on your meteorological background or inform us of any previous order you've made, this way we can tell you are a legit user, otherwise we will assume it is a spammer trying to bypass the application checks. Thanks. -Tim

Request for Heat Index to be Calcuated at AWOS Sites

Post by geophi »

Hi Tim,

Enhancement - While wind chill is calculated for both ASOS and AWOS sites, heat index is not calculated for AWOS sites, actually maybe any MTR that has AUTO text preceding the wind. There are lots of areas where there is a large distance between ASOS sites, and having it calculated for AWOS sites as well would be useful for any analysis or situational awareness. I'm not sure of the reason for this omission. Certainly the dewpoint at AWOS sites can be more frequently wonky than at ASOS sites, but it would be nice to have the option to plot/analyze the HI at all MTR sites.

See below for an example where an ASOS site (KCLL) and AWOS site (KCFD) are nearby, with the same plotted T and Td, but HI is only plotted for the ASOS site KCLL which has a HI of 87. The graphic below that shows a plotted map from the Central Plains with numerous AWOS sites without any HI.

KCFD 301955Z AUTO 00000KT 10SM CLR 27/17 A3014 RMK AO2 T02740174
KCLL 301953Z 00000KT 10SM CLR 28/17 A3012 RMK AO2 SLP195 T02780172
