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.


The Weather Channel tends to weight their long term predictions with seasonal averages. For Friday night they show:
Overnight Low 38°F
Precip 10%
Wind: N 4 mph
Max. Humidity: 67%
Partly Cloudy


For Saturday they show:
High 58°F
Precip 30%
Wind: NE 8 mph
Max. Humidity: 62%
UV Index: 4 Moderate
Sunrise: 7:18 AM CT
Few Showers

For Saturday night they show:
Overnight Low 41°F
Precip 10%
Wind: WSW 4 mph
Max. Humidity: 71%
Mostly Clear

For Sunday they show:
High 60°F
Precip 0%
Wind: N 8 mph
Max. Humidity: 63%
UV Index: 4 Moderate
Sunrise: 7:18 AM CT

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

Friday Night, Jan 13
Low: 43°F RealFeel®: 40°F
Cloudy
Winds E at 10 mph with gusts to 15

Saturday, Jan 14
High: 64°F RealFeel®: 68°F
Partly CLoudy
Winds N at 5 mph with gusts to 16

Saturday Night, Jan 14
Low: 44°F RealFeel®: 44°F
Clear
Winds SW at 6 mph with gusts to 16

Sunday, Jan 15
High: 58°F RealFeel®: 57°F
Mostly Cloudy
Winds SSW at 8 mph with gusts to 22

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!

Glad to see your weather updates. I'd have missed them if you left them off the annual calendar!

Kevin,
Thanks a for posting the weather update. Today's weather was brutal and I hope it only gets better.

I hope cold front is not coming one day too soon. Frankly, I will be very happy with < 55 degrees for the whole run.

Are you gonna be pacing any groups this year?

I applied to pace the 3:30 group, but I wasn't selected. Knowing I wouldn't run the marathon this year, I rested almost all of December. I'm starting back up again, hoping to get in shape in time to run Boston in April.
