Another Fall Like Day

Posted: Updated:

Dave's 7 am Forecast

More sunshine is expected today, although a few clouds will roll in from the north as the remnants of Irma move away from the region. We'll still be on the back side of that low pressure area, bringing the northerly flow. At least one, maybe two more days of very fall like weather will continue with temperatures at or below normal. High pressure will start building in from the west, and this should help to open the Gulf Waters again later this week, so get ready for the return of the humidity.


Expect temperatures to rise into the low to mid 80s. Dew points will stay in the 50s, so the comfort levels remain high. As dew points reach the lower 60s tomorrow, you'll feel the difference.  By the weekend, expect the full force of summer to be back as dew points reach the lower 70s. This will prevent overnight temperatures from getting cool, so expect lows back in the 70s with highs in the low 90s and heat index values approaching 100 again by Saturday and Sunday. Models indicate summer weather will stick around for at least the next two weeks following this weekend.

Not expecting any rainfall today, and not much is expected for the remainder of the week. A few showers may rotate around the back side of Irma's remnants and could affect northern Louisiana. A sprinkle may work as far south as Alexandria. The same is expected for Wednesday as Irma moves into the Ohio Valley. By Thursday and Friday, summertime type showers and storms will be back in the forecast, although nothing higher that 30%.


Hurricane Jose is the only player out in the Atlantic Basin after a very busy couple of weeks. It's weakened a bit again today and now winds are 75mph, a minimal hurricane. Steering currents for Jose are weak, and Jose is expected to loop around itself over the next few days. Wind shear values are moderate, so only minor fluctuations in strength are expected. Farther down the road, Jose should return on a northwestern path toward the East Coast of the U.S., but extended models turn it toward the northeast and back out to the Atlantic in about a week. There's one other area of disturbed weather over the Atlantic, but it doesn't have a great future. Model guidance also shows a somewhat quiet period in the tropics for the next week or so.
