8/6 – Rob Knight’s “More Humid” Friday/Weekend Forecast
The less humid pattern will begin a slow transition later today through the weekend. An area of high-pressure will move into the GOM as a warm front over the N’tern GOM moves north Saturday. The moisture flow will be felt later today as winds will be more southerly. Today should stay relatively dry as we are stuck between the ridge and the approaching trough. Saturday is when precip chances get back to the 30% range as the front moves north into the area. As with any summer chance of rain, isolated to scattered thunderstorms are possible.
High-pressure starts to build westward from the Atlantic starting on Sunday and remains across the southeast states through Thursday. Aloft, a weak high pressure will be centered over the south. Generally southeast flow is expected through the week which will increase moisture values. While there is no large scale forcing present, no fronts and really no major shortwaves, precip chances will be higher Sunday due to the lingering boundary. They stay near 30-40% percent through the week just due to lake/sea breeze boundaries and their outflow boundaries. Locally heavy rainfall is possible in all these storms due to very weak steering flow.
