Weather applet - in the afternoon the 5 day forecast fails

[Afredco]

NOOB here... but I did my best to figure out as much as I could
 however I don't know python so I am not sure

it seems this part (starts at 681 in my code)

                        dayNodes = xmldoc.getElementsByTagName('dayf')[0].getElementsByTagName('day')
                        for dayNode in dayNodes:
                            names = ['HIGH', 'LOW', 'CODE', 'DESCRIPTION', 'PRECIP', 'HUMIDITY', 'WSPEED', 'WDIR', 'WGUST']
                            paths = ['hi', 'low', 'part/icon', 'part/t', 'part/ppcp', 'part/hmid', 'part/wind/s', 'part/wind/t', 'part/wind/gust']

causes a problem in the afternoon when weather.com xml feed nulls the values for <part/icon> and <part/t>

below is the relevant part of xml returned from weather.com for my location (USMD0161)
- notice the <part/icon> value is missing in the afternoon

<day d="0" t="Thursday" dt="Jul 3">
<hi>88</hi>
<low>66</low>
<sunr>5:48 AM</sunr>
<suns>8:40 PM</suns>
