A cold front moved across the region right on schedule yesterday evening with a round of strong to severe storms for some locations. By the time most read this post, the stronger storms will be well removed from the state but the upper level system may still bring some spotty showers across northern Oklahoma for a few hours this morning. This chance will remain rather low but I may keep a slight pop in the forecast through the 10 am hour. More importantly, gusty northwest winds and much cooler air will arrive with highs today staying in the mid to upper 50s north and a few lower 60s south. Temps are now dropping into the 50s near the metro and some upper 40s around the I-35 corridor region. We're basically in a nice pattern for the remainder of the work week before the next strong surface front arrives for the 2nd half of the weekend. It appears our next front will arrive late Saturday night or Sunday morning with a good chance of storms as the front moves southward.
The upper air pattern will quickly take our mid-level low from central Kansas into the upper Midwest later today. Before this feature totally leaves our region, we may see a few more scattered showers or sprinkles for another hour or two. Most data support the clouds sticking around for most of the day before clearing from the west to east by late afternoon or evening. We're counting on these clouds sticking around for a while and this should keep our highs in the 50s for northern Oklahoma.
As the sky clears overnight and the surface dew points begin drying with north winds, the temps will drop. Our morning lows will be in the upper 30s and lower 40s Wednesday morning with a surface ridge of high pressure centered near us by afternoon. This will keep the sky blue and sunny with highs in the mid-60s along with light north winds. The surface ridge moves eastward by Thursday morning with a south wind return flow lasting into the 1st half of the weekend. Most data support another robust warm-up with Thursday afternoon in the lower 80s and Friday into the mid and upper 80s.
This weekend the next upper level system will quickly move from the western US. across the central plains by Saturday night into Sunday morning. A surface front will develop and move southeastward by late Saturday night or Sunday morning with increasing storm chances for the state. It's too early to pinpoint the severe weather threats but the main dynamic energy appears to be staying north of the southern plains and we’re seeing signals that most of the precip may be post-frontal. As the front passes Sunday, we'll see another cool-down into the following week leading into fall break for school students in Oklahoma.
Thanks for reading the Tuesday morning weather discussion and blog.
