We’re looking at a spectacular weather day across eastern Oklahoma. A few clouds may brush far eastern Oklahoma early this morning but should not be a major player in the pattern for the day. Also, a very few areas of patchy fog may be possible across the state line into northwest Arkansas if the clouds thin in these areas before sunrise. Even if this occurs, it will mix out quickly with full sunshine and beautiful weather this afternoon as a surface ridge of high pressure settles directly over northeast Oklahoma. While we’ll see some variability in wind direction across eastern Oklahoma, the predominate winds will be from the north around 5 to 8 mph for the day. Later tonight the surface ridge will move eastward with south winds returning across the areas Thursday through Saturday. And with the south winds will come the warmer temps. After yesterday’s highs in the 50s and today's highs in the mid-60s, we’re back into the 80s Friday into Saturday with highs nearing 90 Saturday afternoon. #Ugh. But another decent fall front will arrive later Saturday night into Sunday morning with additional storms and another minor reduction in temps for a few days next week.
The upper air pattern will support our next upper level system developing across western Canada and quickly moving eastward into the Hudson Bay region Thursday and Friday. As this wave moves eastward, another fast-developing short-wave will form out the pacific northwest and move basically west to east Friday into Saturday. The trajectory is mostly zonal with the majority of the superior dynamics located across the central plains Saturday afternoon and evening. But enough energy will brush the southern plains to help push a surface front southward from southern Kansas into northwestern OK Saturday night into Sunday morning. As our south winds return Thursday, low level moisture will attempt a fast comeback into the state Friday and Saturday. This moisture is not expected to be overly deep but will support a decent round of storms during this period. Severe weather threats remain a little iffy at this point but I would anticipate a greater threat Saturday across central or eastern Kansas with a quasi-warm front developing along and east of the surface cyclone. As this system ejects northeast Saturday night, it will drag the front southward with increasing thunderstorm chances. This front appears progressive and would clear the area early Sunday morning with pleasant weather for the majority of the day. The weather for the remainder of the following week looks pleasant until the next system arrives around the 18th or 19th.
Thanks for reading the Wednesday morning weather discussion and blog.
