I'm kind of a weather nut and spend quite a bit of time reading the raw forecast models the Weather Service uses to develop its official forecasts. Data is just starting to come in for the week of MacWorld. Here's my private long-range forecast for the week of MacWorld 2004 San Francisco. It's very preliminary of course, and this far out the forecast could easily change, so "caveat lector" applies. I will update every day or so. I hope MR readers find this useful for their planning. (At this point, I'd pack my umbrella.) Monday, January 5 Partly cloudy, clouds increasing in afternoon with a possibility of light drizzle towards evening. Light westerly winds. High: 55 Low: 48 Tuesday, January 6 Mostly cloudy, possible light drizzle all day. Westerly winds to 10 mph. High: 57 Low: 52 Wednesday, January 7 Mostly cloudy, with light drizzle in the AM but some sun possible by afternoon. Southerly winds picking up to 15 mph later in the day. High: 59 Low: 51 Thursday, January 8 Increasing clouds, breezy overnight, with rain developing in the morning and continuing through the day. High: 58 Low: 52 Friday, January 9 No data yet.
