A nice weekend ahead & keeping track of "Harvey"
A beautiful late August weekend for the Tennessee Valley! Temperatures just a tad below average should stick around through Sunday. Meanwhile, the big weather story is "Harvey" and its effects on Texas.
Some very nice weather to end the week and start the weekend. The dry air should once again allow morning temperatures to drop into the lower 60s. But, some areas north and east could drop into the 50s. Sunshine and lower than normal humidity conditions through the afternoon with highs in the mid 80s. Some of our local mountain tops could remain in the upper 70s through the afternoon,
Kickoff conditions for area high school football games should be very nice in the 70s Friday Evening. Then, 60s again for the overnight hours and through Saturday Morning.
A great "outdoors" weekend with a sunny to partly sunny sky both days. Humidity levels up a tad, but still not the usual August levels, Afternoon highs should remain in the mid/upper 80s and morning lows in the mid 60s. There could be a few pop up afternoon t-showers, but mainly over the eastern mountains.
Not much will change through Monday similar conditions again!.
Harvey could be the first hurricane to make landfall in Texas since 2008. And, possibly the first Major Hurricane to make landfall in the US since 2005. But, there are still some questions about the exact path in the days ahead. Harvey could reach Major Hurricane strength (Category 3 or higher) as it nears the south Texas coast. An inland dome of high pressure west of Texas could stall the storm just offshore or just inland, This stalling motion could be devastating for not only the Texas coast, but also inland. The hurricane strength wind and surge could last for a prolonged period of time for the immediate coast. Then, farther inland, a prolonged period of heavy rain could lead to devastating (record) flooding. Some computer models show the potential of 15"-25" over a wide section of eastern and coastal Texas, but some isolated amounts near 35".
Harvey could linger around the upper Texas coast through early next week due to very little upper level support to move in farther inland. So, this means for us that our local weather should not be affected through early next week.
Longer range model data into mid/late next week varies quite a bit. The European Model has an upper level trough pulling Harvey inland and into the Ohio Valley by late next week and into the weekend. That scenario could bring us some rain late next week. But, that's a big "If". Meanwhile, the longer range GFS model has also has an upper level trough pulling Harvey inland late next week, but at a slower pace. So, our weather could be impacted later next week, but to what degree remains a question. So, as with any tropical system, we will have to take it one day at a time. And, this one could have many changes just in a 2-3 day span.
