Only Subtle Changes Ahead… Plus an Isaac Update
Unseasonably cool temperatures once again started the day across the Tennessee Valley with lowest temps out in the higher terrain of Jackson and DeKalb Counties.
Primarily calm conditions will prevail again today with a weak area of high pressure the main influence on our weather conditions. However, we will be slightly warmer and more humid over the next few days with a slim chance for isolated showers returning to the forecast by Saturday as low pressure to our west gives us a southerly flow.
We’re keeping an eye on Tropical Storm Isaac, which is currently spinning south of Puerto Rico. The official forecast track of the National Hurricane Center now has Isaac intensifying to Category 1 strength as it reemerges in the Gulf after passing through Cuba. This scenario takes it west of the Western Florida coast toward landfall somewhere along the Florida Panhandle mid-week.
Of course, uncertainty is very high this far out, and don’t be surprised if there are radical changes to the forecast during the coming days. Regardless, if we are to see any influence on our weather from this storm (and there’s a good chance we won’t) it will likely only be in the form of rain sometime late next week (8 to 10 days from now).
