Drier & slightly cooler air set to return

Thursday_Morning_Lows.png

Late August heat should be replaced by drier and slightly cooler air beginning late Wednesday and continues through late week. We will also keep an eye on the southern Gulf for the possible redevelopment of "Harvey"

(IMAGE GALLERY ABOVE: #1. COOL FRONT BRINGS A CLOUDY START WEDNESDAY AND POSSIBLE A FEW SHOWERS........#2. DRIER AIR MOVES IN WEDNESDAY AFTERNOON.........#3. A COMFORTABLE MORNING THURSDAY WITH 60S AND EVEN A FEW SPOTS IN THE 50S.......#4. "HARVEY" COULD REDEVELOP IN THE GULF)

DRIER AIR RETURNS

A cool front moves through the Tennessee Valley Wednesday Morning. This front should not be a big rain producer though. Some scattered showers/t-showers could occur during the night Tuesday Night through Wednesday Morning, but many areas will stay cloudy to partly cloudy. A cloudy start Wednesday and again possible a stray shower. But, the possibility of widespread showers Wednesday Morning remain low and isolated. Clouds should move out as the afternoon progresses and drier air filters in. Temperatures won't be quite as hot as it has been with afternoon highs in the mid/upper 80s.

One of the benefits of the drier air will mean some much more comfortable mornings Thursday and Friday. Low/mid 60s in most parts of our viewing area both mornings. But, some outlying areas and mountain locations could dip into the upper 50s. The other benefit of the drier air is that fact that it will not be as humid Thursday and Friday afternoon. Afternoon highs should also stay below average for late August in the mid 80s.

This also means that nearly perfect weather conditions can be expected for Friday Night's high school football games!

WEEKEND OUTLOOK

The early outlook for the weekend includes a gradual increase in humidity levels. But, afternoon temperatures should remain below average. Partly sunny Saturday with mid/upper 80s for highs along with the chance for some pop up t-showers, but not everywhere. The could be more clouds Sunday along with the possibility for a better chance of afternoon/evening scattered t-showers.

WATCHING THE GULF

The remnants of "Harvey" could redevelop in the Gulf of Mexico. Forecast models show the possibility of a slow moving system in the western Gulf that could bring heavy rain over eastern Texas, The slow movement could mean a prolonged period of heavy rain in that region. As for what this means for us, we will have to watch this a day at a time (rule of thumb for any tropical system). Longer range forecast models (GFS and European) show the possibility of what's left of "Harvey" moving inland over the Mississippi Valley. This could mean increasing rain chances locally by mid to late next week. But, that remains unclear as we wait and see how strong of a system develops in the days ahead. So, more questions than answers at this time. August 15th through October 15th is typically the most active or peak period of the hurricane season.

As always, you can depend on the StormTrack 9 Team for updates!
