On the 8-Day Forecast

We're still a ways out from the Houston Marathon, but I enjoy tracking the forecast.

The 8-day model forecast now includes marathon morning. Conditions look really good right now, with temperature in the low 40s and a light wind [the graph is in UTC, six hours ahead of Houston]. The NWS forecast discussion indicates there's quite a bit of uncertainty from Thursday on.

The Weather Channel tends to weight their long term predictions with seasonal averages. For Saturday night they show:
Overnight Low 47°F
Precip 20%
Wind: ENE 3 mph
Max. Humidity: 88%

For Sunday they show:
High 68°F
Precip 40%
Wind: NNE 12 mph
Max. Humidity: 75%
UV Index: 4 Moderate
Sunrise: 7:18 AM CT

AccuWeather now has Saturday night and Sunday on their 6 to 10 day forecast. They predict:

Saturday Night, Jan 12
Low: 38 °F RealFeel®: 31 °F
Partly cloudy

Sunday, Jan 13
High: 58 °F RealFeel®: 54 °F
Mostly sunny
