Another chilly start underway across Eastern Oklahoma this morning. Many locations will see morning temps in the mid-20s. Highs this afternoon will reach the mid and upper 50s along with abundant sunshine and a return of southwest winds from 10 to 15 mph. This warming trend also continues Wednesday with highs reaching the upper 50s and lower 60s before another cold front moves across the state ushering cooler or colder weather back into part of the area Friday through the weekend.
The upper air pattern will remain quite progressive for the next few weeks. I think we’ll track a system nearby about every two to four days but the overall impact on sensible weather may be negligible for a while. A fast-moving upper trough moves across central Texas late tonight into Wednesday and will have little impact on our weather. The next upper-level feature of interests arrives Thursday with a powerful cold-core low dropping from Canada into the upper Midwest. As this low pivots across the Great Lakes, colder air will filter southward behind this system and will invade a large portion of the Midwest and northeastern U.S. But the trajectory of this feature suggests the coldest air may stay slightly northwest of our immediate area for the weekend. Close Call. I have the highs into the mid and upper 40s this weekend with morning lows in the upper 20s and lower 30s.
Precipitation chances this week continue to appear meager for most locations. As the Thursday cold front passes our area, a few showers or snow flurries may arrive Thursday morning and again early Friday morning as a strong push northwest winds also will be arriving. Any light showers or flurries would have no major impact the chance will remain near 10% for this period. Windy weather is also likely Friday with northwest winds from 20 to 35 mph increasing the fire spread rate across a large portion of northern OK and southern Kansas.
This weekend, as the main upper trough stays northwest, a weak disturbance may travel down the intermountain region and move across the high plains of Texas into part of the southern plains Saturday evening. Most data keep our area dry but there’s just enough support in some data to keep a low chance for some light showers Saturday evening to our southwest.
Thanks for reading the Tuesday morning weather discussion and blog.
Have a super great day!’
