Alan Crone's Weather Blog: Cold Front Bringing Fall To Oklahoma

Residual moisture from the last rain event combined with dew points in the upper 60s and lower 70s are combining to produce some patchy but dense fog across part of the state this morning including some locations across northeastern and eastern OK.   Visibility may be hampered through the early morning hours in a few spots, so please use caution while traveling if you do encounter some patchy fog.  Otherwise temperatures in the upper 60s and lower 70s this morning will move into the upper 80s today across eastern OK and the lower 90s across central and western OK along with a return of east to southeast winds across eastern sections of the state.   The next storm system is poised to move across the area late tonight into Friday morning bringing some rain and thunderstorm activity across southern Kansas and northeastern OK.

A few of the storms may still be strong to severe for an hour or so pre-dawn Friday but should weaken as they move southeast during the morning hours.   More importantly, this front will be the first real fall front of the season.   A modified Canadian air-mass will arrive across the Midwestern U.S. and enter the Missouri Valley.   Some of this dry and cool air will spread into Oklahoma with a noticeable drop in both daytime highs and overnight lows.   If my timing is correct with the Friday morning storms, Friday night football should be wonderful regarding the weather conditions.   Cool air will slide into the state with Saturday morning lows in the lower to mid-50s near the metro.   Daytime highs Saturday afternoon will range from the upper 60s across far northeastern OK and the lower 70s near the metro.   Some mid-70s will be likely across far southeastern OK and northeastern TX.  

Sunday morning we’ll see even cooler air in the Tulsa metro with morning lows in the lower 50s.   A number of locations northeast of the metro will see temperatures dropping into the upper 40s along with mostly clear sky and light wind.   Sunday afternoon highs will range from the mid to upper 70s along with a return of southeasterly winds around 10 to 15 mph.   After this weekend, the upper air pattern will once again undergo a change.

The weekend will feature a healthy northwest flow over the state as a strong trough develops across the Great Lakes and deepens across the upper Midwest.   Cool and dry air will circulate across the northern High plains southward into the state this weekend.   Locations across the northeastern U.S. into the Midwest will experience unseasonably cool air this weekend.

Next week the eastern trough begins to migrate eastward as a strong trough develops across the pacific and begins influencing weather on the west coast.   The result will be the development of a southwesterly upper air flow moving near the southern plains next week.  This pattern will support a return of southerly surface winds, including low level moisture, and temperatures moving near the seasonal averages for both morning lows and daytime highs.   This pattern will eventually bring a storm system in the state sometime late next week, possibly Thursday or more so Friday.   But that’s many days out.   Let’s enjoy this great fall weather we’re going to experience Friday through the weekend.  

Thanks for reading the Thursday morning weather discussion and blog.

Have a super great day!
