The summer-like pattern will stick around for the rest of the week before some noticeable changes take place this weekend with increasing storm chances and some temperatures closer to the seasonal average. Highs today, however, will continue to be well above the average with 94 to 98 along with heat index values near 100 to 108.
We don’t have a lot of changes today compared to yesterday’s synoptic set up: a ridge of high pressure in the mid-levels of the atmosphere will be the dominate feature through the end of the week. The result will be sinking compressing air for most locators resulting in unseasonably warm conditions. The influx of tropical moisture across eastern OK will yield temp heat index numbers around 100 to 108 today. Dew points did not mix down yesterday and a short-term heat advisory was issued. We may see another advisory later today. Regardless, keep hydrated and take some breaks in this late summer-early fall heat wave. One isolated storm may be possible later this afternoon across far southeastern OK but the odds are extremely low.
The ridge should weaken and slowly migrate eastward by Thursday into Friday. This should allow for a minor reduction with morning lows near 68-70 and daytime highs around 92 to 94 through this period.
This weekend should feature the arrival of a storm system for at least part of the state as the ridge begins to migrate eastward and a stronger upper level low will develop across the desert southwest. This low may remain too far west to impact the state this weekend and early next week, but by the middle of next week should result in some changes.
This weekend a few storms will be likely Saturday but the higher coverage may remain west of most locations for most of the day. Sunday more scattered storms will become more noticeable and the increased clouds will act to keep the temps down near normal. Data this morning is slightly more robust with the coverage of precipitation and therefore the reduction in temperatures.
By early to the middle part of next week the main westerlies will begin slowly sinking southward and the above mentioned southwestern low will slowly advance eastward. This pattern will bring scattered showers and storms back to the area along with a decent taste of fall weather by the end of the week.
Thanks for reading the Tuesday morning weather discussion and blog.
Have a super great day!
