T-3 & M-4 OT and Houston Marathon Weather Forecast

The forecast continues to show more Gulf air coming in this weekend, but Marathon morning still looks good. But if the forecast keeps changing...?
SURFACE HIGH PRESSURE BUILDING INTO THE AREA WILL BRING NEAR IDEAL RADIATIONAL COOLING CONDITIONS TO THE AREA THURSDAY NIGHT THROUGH FRIDAY MORNING POTENTIALLY RESULTING IN SEVERAL HOURS OF TEMPERATURES BELOW FREEZING. A GRADUAL WARM UP CAN THEN BE EXPECTED OVER THE WEEKEND AND INTO THE FIRST COUPLE DAYS OF NEXT WEEK AS SURFACE HIGH PRESSURE MOVES OFF TO THE EAST AND A WARMER RETURN FLOW OFF THE GULF SETS UP. WILL CARRY 20% POPS FOR SHOWERS SUNDAY AFTERNOON THROUGH TUESDAY MORNING.


The 84-hour model has the temperature near 40°F but with nearly no wind for the OTs and no rain. The 7.5-day model has Sunday morning near 40 but with an increasing wind from the south and humidity increasing during the day. The text version of the GFSX MOS model for Hobby Airport still shows a much colder low of 34°F with the wind at 5 mph Saturday morning and a low of 39°F and winds at 5 mph Sunday morning.





The hourly forecast still shows a cooler morning low temperature at 35°F, dew point at 24°F, and a north wind at 2 mph. At 10AM, it shows 46°F, dew point at 25°F, and a east "wind" at 1 mph. For 7AM Sunday, the forecast shows 40°F, dew point at 40°F, and a south-southeast wind at 2 mph and at 10AM, it shows 50°F, dew point at 43°F, and a southeast wind at 6 mph. Saturday is still nearly perfect, and Sunday is still very good but if the trend keeps going, Sunday might get to a little warm and humid.
