A Nice Break From The Heat

Temperatures are running anywhere from 7 to 12 degrees cooler this morning compared to yesterday at this hour as a result of drier air moving across the region.  This air-mass characterized by lower to mid-60 degree dew point temperatures will persist through Friday morning.   The result will be pleasant morning lows and lower relative humidity values for the afternoon through Friday.   A return of southeasterly surface flow Friday afternoon and evening will slowly increase low level moisture this weekend.   Temperatures will also slowly climb through the weekend into early next week.   Temperature heat index values will remain well below advisory or warning criteria.

The mid-level ridge of high pressure is located to our west this morning and will slowly migrate to near the four corners region over the next 36 to 48 hours.   A few showers or storms may still be possible today across part of the high plains of Texas into part of western OK, but this activity will remain west of our areas.  A repeat performance may occur Thursday in the same areas.    A weak upper level disturbance may brush northeastern OK Friday with nothing more than a few clouds.  The atmosphere will more than likely remain too dry to produce any significant precipitation across our area.   Next week the pattern will support the return of warmer and slightly more humid conditions but the lack of any significant disturbance or system will preclude the mention of showers or storms at this point.

Northeast winds around 5 to 12 mph will be likely.   Temperatures today may remain in the mid to upper 80s across most if not all of northeastern OK and southeastern Kansas.   The lone exception may be the actual airport reporting locations for Tulsa International and Jenks Riverside where temps may hit 90.   Yesterday’s official high from Tulsa International was 92, but the mesonet location was 90.   Almost all mesonet sites across northeastern OK remained in the upper 80s yesterday for maximum temps.  Overnight and Thursday morning lows in the lower to mid-60s will be followed by highs Thursday afternoon in the upper 80s and lower 90s.   Friday morning lows in the upper 60s and lower 70s will be likely.   Southeast winds will return by afternoon allowing afternoon highs in the lower 90s.

The weekend should feature lows in the lower 70s and highs in the lower to mid-90s.   Gulf moisture will not be able to arrive across the region but a slight increase in dew point temperatures will increase the temperature heat index Monday and Tuesday.

There are some differences in the data for the middle to end of next week and I’ll not ponder too much at this point since we’re many days out.   But a front may arrive around Thursday of next week with some storms.

Thanks for reading the Wednesday morning weather discussion and blog.

Have a super great day!
