8/21 – Trey Tonnessen’s “Green Cut” Wednesday Night Forecast

Meteorologist Trey Tonnessen

Expect Friday to be mostly similar to the previous two days as dry air looks to hang onto the area for one more day. However, medium-range models suggest that the current impulse coming down across the central US gets cut off via a Rex Block over the northeastern Gulf. This is due to the aforementioned ridge over Texas poking into Ozarks over Missouri and Arkansas. This cut off low helps break down the ridging and subsidence across the area and allows better moisture quality into the area. The medium-range guidance suggests mainly the southern half of our area will at least get back to normal moisture values by Saturday. Medium-range clustering suggests that after the upper-level low slides westward under the ridge, more ridging build in across the area. This will inevitably increase temps and bring us back into a “normal” summertime convective pattern
