We've been enjoying a beautiful preview of fall for the past couple of days, thanks to the season's first significant cold front that passed through Houston on Saturday. Humidity has been low, temperatures have been hovering a touch below normal and the skies have been a beautiful, bright blue.
As anyone familiar with Houston weather will tell you, though, stretches of weather like this are always short-lived in early September. Get ready for a return of the summer sauna!
As a ridge of high pressure moves toward the east coast, our wind will turn from its current northeast direction to a southeast wind off the Gulf of Mexico. We all know what that means: Humid air creeps into the area. This change will happen gradually through Wednesday, when we see enough moisture in the atmosphere to spark scattered showers along the coast. By Thursday and Friday, the chance for afternoon showers will migrate inland so that we all should catch at least one passing shower or thunderstorm by week's end.
Temperatures for the rest of the week should hover near 90, so we don't expect a big heat wave, but with the humidity coming back full-force the "feels-like" temperature will easily make it into the mid and upper 90s.
By Saturday we could see our second relief from the humidity in the form of a cold front. Unlike last weekend's front, however, we're not quite sure whether this one will make it all the way through the region or hang up along the coast. In the first scenario, we should clear out nicely and cool down nicely by Sunday. In the second scenario, the humidity stays high and rain chances continue along the coast through the weekend. We'll be studying the data closely over the next couple of days to determine which scenario plays out.
In the meantime, hopefully you haven't put your summer tank tops into storage just yet. You'll need them!
