Alan Crone: Tracking A Midweek System

A developing upper level trough will bring a few showers into eastern Oklahoma late Tuesday night into Wednesday as the system strengthens while exiting our area early Thursday.   In advance of this system, cloud cover is likely tomorrow before a few showers populate part of eastern Oklahoma mostly Wednesday.  This chance will remain somewhat low due to the coverage of the expected showers. We’re in between storm systems for a few days with rather pleasant and uneventful weather expected today across eastern Oklahoma.  Highs today will be in the upper 50s to lower 60s with sunny conditions this morning to midday before clouds arrive this afternoon and tonight. 

As the system exits early Thursday, a strong pressure gradient will return on the backside of the departing storm system with strong north winds Thursday, possibly nearing advisory levels.  Northwest flow aloft will remain across the state this weekend with pleasant weather Saturday before another surface front crosses the area Sunday with slightly colder weather.  Active weather is likely to return next week passed on the projected developing upper air pattern.  At this point, we see no major arctic air intrusions across the state during the next 7 days. 

A weak system moved across eastern Oklahoma yesterday bringing a wind shift and a few clouds.  These clouds have attempted to clear-out overnight and temps have dropped to just above the local dew point in some locations. 

Patchy, yet dense fog is possible in a few locations early this morning, mostly across southeastern Oklahoma and northwestern Arkansas and in the typical valley locations of eastern Oklahoma.  A dense fog advisory is currently posted for part of southeastern OK and locations across Arkansas.  A few additional counties could be included across east-central Oklahoma before sunrise.  Regardless, prepare for rapid changes in visibility early this morning in a few locations.  Temps this morning will remain cold and slightly below freezing.  The odds of any significant freezing fog seem low but not totally impossible in these valley spots.  Daytime highs will be expected in the upper 50s near 60 with light winds today. 

Thanks for reading the Monday morning weather discussion and blog.
