Same old, same old
Forecast Discussion: Aside from the ever-present August heat and humidity, there is little else destabilizing our atmosphere. The only surface weather feature of note is a weak high pressure system in the northeastern Gulf of Mexico and a broad upper level ridge to our west. Combined the two systems will slacken off shower development during the afternoon hours through the weekend. Despite the weak suppression of surface air, the high heat and humidity will allow very isolated convection to spark off along sea breeze boundaries the next several days. Look for rain in only about 20% of the area within Southeast Louisiana and Southern Mississippi.
Today and Tonight: Blue skies and sunshine early will allow a quick warmup to 90° by lunchtime. The hefty heat and humidity will bubble up a cumulus cloud deck this afternoon-a few of which could squeeze out a thundershower. By and large though, most locations will stay partly sunny and dry with highs in the mid-90s. Overnight will be quiet but sticky with lows in the mid-70s.
Into the Weekend: Friday and the weekend are copy and paste weather forecasts-- partly sunny skies with isolated afternoon thundershowers. Highs will be in the mid-90s with lows in the mid-70s. High dew points will lead to afternoon feels-like readings exceeding 100°.
The Tropics: The tropics are queit and Bertha is no more! Hurricane Iselle however, in the Pacific, will be Hawaii's first landfalling hurricane in years. Iselle's current sustained winds are at 90mph and she is expected to make landfall Thursday night.
