OK...Let's Try This Again (Weekend Weather Blog)

OK…let’s try this again.

Last weekend’s forecast wound up being a “bust” for many. A fairly stout cold front for August triggered heavy thunderstorms Friday, but by last Saturday (Aug 13) a pool of drier air began to settle into Texoma. The dry air deepened on Sunday and this was not expected, making for a much drier result. A low-pressure cell in Louisiana, the one that caused catastrophic flooding there, helped to maintain the dry flow here.

This time, however, there’s an opposite event in the works as tropical moisture flows into our skies through the weekend with southerly winds. This will occur at both the surface and upper levels, pointing to heavy rainfall potential.

Meanwhile, a series of weak waves aloft (the “blue X” I show during the weather broadcast) and an arriving surface cold front will all work to keep the atmosphere quite unstable through the weekend. Daytime heating will also play a role.

Severe weather potential in these cases is very low with lightning and heavy rainfall the primary threats. While any thunderstorm can produce gusty winds, they should generally 40 mph or less in these cells.

This looks to be a 3 to 6 inch rainfall event; stay tuned for an update on Thursday and Friday nights to this blog.
