This will be the final forecast for the Houston Marathon on Sunday, Jan. 17th. The TL;DR version is:
OH MY GOD THE WEATHER IS GOING TO BE NIGH PERFECT.
Today’s light northwesterly winds herald the arrival of a cool front, and we’ll see colder air steadily advecting into the area over the next couple of days. Moisture levels aren’t particularly high in the atmosphere, but there will be a chance of light rain tomorrow, likely during the afternoon hours. Cold air really takes hold by Saturday night. And so, for the marathon …
Start line temperature: 41°
Temperature at noon: 53°
Skies: Partly to mostly clear
Winds: 5-10 miles out of N-NE
Ideally the winds would be zero, but since they’re coming out of the north we can be assured of low dew points, which means low humidity and ideal cooling.
