Well, it appears that Monica Garcia is doing the weather on Saturdays. However, Sundays have been a mixed bag. Paul Horton had been doing weather for the past 2 or 3 weeks. Then, yesterday, Kim Powell (!) did the weather on the evening newscasts. On the 5:30pm, she seemed reasonably comfortable and actually better than Garcia. This may have just been a holiday weekend thing (since Paul did the weather on Friday). As brian4 mentioned previously, it takes a spreadsheet to figure out what they're doing.
