Showers with Cool Air

The dry air in the lower and mid levels of the atmosphere worked against our precip coverage yesterday across portions of eastern OK.  Some locations received relatively small amounts, but every drop is a blessing in a major drought.  

The temps yesterday ranged from 58 to 62 in the Tulsa metro with some upper 60s across the far southeastern sections of the state.  We're in store for more unseasonably cool air today before the warmer air currently located south of the Red River begins to move northward.  The temperature forecast will remain tricky today due to the warm front attempting to move northward during the day.  The machine numbers indicate Tulsa will move into the lower 70s this afternoon with some mid 70s possible across southern sections of the region.  While this is possible, I think the front will be slower to move northward and I'll keep the Tulsa metro in the mid to upper 60s with the 70s confined to areas south of I-40.  

This morning we find a few areas of light showers across northern OK with locations reporting temps in the lower to mid 50s.  Closer to the Red River Valley, a cluster of thunderstorm activity has developed and will move into south-central OK this morning. 

Later tonight a surface area of low pressure is expected to form to our northwest allowing the warm front currently south of the Red River to begin moving northward.  Showers and storms will be possible Saturday morning across the northern half of the state.  A few of these may produce some lightning but no severe storms will be expected. 

 The rest of the extended periods will remain with warmer air and a chance of showers and storms.

 The EURO brings a boundary into the area Monday with clear and dry conditions Tuesday through Thursday, while the GFS doesn't bring the boundary through the region until Wednesday.  At this point, I'll side with the GFS and keep the mention of showers and storms across the early part of next week.

As always, I want to thank you for reading the weather blog.  Have a super weekend.
