Summer Weather Returns Soon

We’re in the running again for more scattered showers and storms this morning through at least midday to early afternoon with highs expected in the mid to upper 80s north and possibly warmer south.

A stout upper-level trough is ejecting across the central and northern plains today and tomorrow while a mid-level ridge of high pressure will expand from Texas across part of Oklahoma during the next 36 to 48 hours. This will eventually shove the precip. chances out of the state and bring the heat and humidity back for our area.

Highs this weekend will be in the lower to mid-90s along with heat index values from 100 to 107.

It’s possible that some heat advisories may be required for some locations.

The ridge will migrate slightly eastward by the middle of next week with another western trough establishing yet the rain chances will remain void of the extended forecast at this point once we get past today and tomorrow.

The southern end of some mid- and upper-level forcing will brush the northern third of the state this morning through early afternoon. This morning, a low-level jet should also increase west and north of the area but may migrate eastward this morning.

The exact coverage of precip. remains a mystery due to some inconsistencies in some of the data. I don’t think I’ll stray too far from the current forecast and will keep the higher chances along the northern OK and southern Kansas vicinity.

The metro will be (should be) on the southern end of this precip chance for today. Severe weather is not expected in our area. Locations south of the Tulsa metro will have a much lower probability compared to the north. The time line will keep a slight chance this morning with the best window of opportunity around 10 a.m. to 3 p.m.

A few leftovers may float into northern OK early tomorrow before the ridge expands and ends the chance.

South winds will return today and continue through the extended portion of the forecast bringing higher dew points back into the eastern third of the state.

Temps will be returning into the mid-90s this weekend as the summer heat and humidity will stick around for all of next week.  

Thanks for reading the Thursday morning weather discussion and blog.
