Hi Guys!
Tooltip...
Great! For future referense if someone want to customize the tooltip, its css-stuff are found in jquery.wxsim.allinone.js at line 61 are a "function showTooltip".

Missing icon...
Humm...We need to try to figure out what is the "raw" name (like nstsra) what it try to parse from, will add some debuginfo to alt-text so we see, ready in 1 hour.
Lastret...
The script is built so there are 5 choosen from the temperetures and 5 from the rest. Not fully sure in wich order the temps are if choose different but i have
AIR DEW WCF HT.I BLYR
Where BLYR is not used, its just as a fill there...
The script itself are then parsing the values backvards (most to right are no 0) because the wxtype-txt caused else some problems while parsing.
IE7..
Yeah, thats a odd issue, only shown in IE7 and IE8 compatible view...Not fully sure yet how to solve it, both issues are normal style-settings in the code what look like IE igonre...damn strange...

EDIT: Debugtext added to to the alt-text for "plaintext-forecast", changed file wxsim.allinone.plaintextparser.php or at line 570 change
$WXSIMbic[$i] = "<img src=\"$iconDir$newicon\" alt=\"\" />";to
$WXSIMbic[$i] = "<img src=\"$iconDir$newicon\" alt=\"$ic||$WXSIMpop[$i]\" />";That should tell us some more info about the icon hopefully...
