OT and Houston Marathon Weather Guesses T-7 & M-8

It's warm and humid again today, but the models still show a cold front arriving Tuesday and staying through next Monday. That's a long time for a cold front to hang around this winter. I wonder if it will really happen that way. The cold fronts this year seem to turn around in a day or two, and the warm Gulf air almost immediately raises temperatures and humidity. I think the forecast for the OTs is OK, but I'd be surprised if the cool weather hangs along through Sunday.

The 7.5-day model includes both races now. [the graph is in UTC, six hours ahead of Houston] The model still has the temperature in the 40°Fs with a very light north wind now. Sunday morning also starts in the 40s but with a little stronger east wind. The text version of the GFSX MOS model for Hobby Airport shows a low of 47°F and stronger winds (11mph) Saturday morning and a low of 39°F and stronger winds (13mph) Sunday morning.



The hourly forecast now shows conditions for the OTs. It shows a colder morning low temperature at 40°F with a north wind at 8 mph.

It will be warmer than where these guys have been training.


I wouldn't be surprised if conditions were similar to where the Brooks/Hansons Group has been training.


Desiree looks good!
