We’re sticking with persistence for the next few days before some more noticeable changes may occur later in the weekend into early next week. This means what has happened in the past will more than likely happen in the future. In other words, the temps will remain steady for the next few days with lows in the lower 70s and highs in the lower 90s. I’m sure you noticed the influx of additional low-level moisture yesterday that resulted in the increased temperature heat index values during the afternoon. This will also continue today and will slowly increase a degree or two through Wednesday.
By Wednesday night into Thursday and then also into part of the weekend the pattern will change slightly offering a window of opportunity for a few storms to move from southern Kansas into northern Oklahoma as the upper air flow becomes more from the northwest to southeast. Our friends and neighbors across far western Oklahoma will experience a few storms later today and tonight as they develop ahead of the high plains dry line. These storms will move eastward and may possibly cross the I-35 corridor region before falling apart later tonight. A few isolated storms may also develop across northeast Texas and extreme southeastern Oklahoma this afternoon but will also remain well removed for most eastern Oklahoma.
Most data continue to offer some signals for a small complex of storms to impact part of northeastern Oklahoma Wednesday evening into pre-dawn Thursday morning. Another signal is present also for Thursday late into Friday morning. Our forecast continues to have these probabilities displayed. Any of these storms could be severe with damaging winds and some hail the main threat.
The weak front to our north will move closer to southern Kansas by the end of the week and will more than likely stall or become totally diffuse by the weekend. Data also suggest we may see a slight increase in temps Saturday with increasing humidity allowing heat index numbers to approach criteria levels, at or over 105. The data this morning takes the weak front and moves it southward across northern Oklahoma Sunday into Monday. This is slightly suspect compared to yesterday’s data. We’ll not make any major changes to the Sunday or Monday period, at least at this point, but will give the data another run or two before lower the temps a few degrees.
Most data also continue to express the general trend of typical June weather for another two weeks before the mid-level ridge begins to dominate the southern plains.
Have a super great day!
