Alan Crone's Weather Blog: Cold Front Moves Into NE Oklahoma

We're tracking a slow moving cold front near northern OK early this morning. This boundary, combined with a fast moving upper wave across the Midwest, was responsible for some scattered showers and storms last night across part of southern Kansas and northern OK. This upper wave is removed from the region this morning, but we're still experiencing a few of these left-over showers and storms at post time. The coverage continues to dwindle. We'll keep a few showers and storms in the forecast this morning near northern OK and later today across the southern sections of the state, but the chances will remain remote for many locations.
This boundary will slide southward later today and be positioned across part of central or southeastern OK by later this afternoon. Daytime heating into the upper 80s to lower 90s and should allow a few isolated storms to develop this afternoon and tonight across eastern OK, but the chance and coverage will remain low. After the early morning hours, the overall chance this afternoon will remain near 20%.
This boundary may still be intact Tuesday early morning across southern or east-central OK with another outside chance of a storm. This front is expected to quickly become diffuse early tomorrow morning with winds returning out of the south around 5 to 10 mph. Our probabilities will remain very low and generally around 10%.
Temperatures will be in the upper 80s and lower 90s today along with north winds at less than 10 mph. Daytime highs will move back into 90s late this week with Tuesday and Wednesday afternoon highs from 92 to 95.
The upper air pattern has changed compared to last week. The mid-level ridge of high pressure has flattened and is now located to the southwest of the state. A trough located across the mid-west into the northeastern U.S. will allow a small window of a northwesterly flow brushing the central plains today and tomorrow. The flow is expected to transition to a southwesterly flow late this week with another disturbance nearing the state. The main westerlies aloft continue to migrate northward but our late week disturbance combined with rich low level moisture will be enough to trigger a few scattered showers and storms Friday into part of the weekend.
Thanks for reading the Monday morning weather discussion and blog.
Have a super great day!
