Excessive Heat Warning Remains

The morning temperatures have cooled a few degrees as a weak boundary has moved across the region.  Later today the heat will return with highs from 106 to 110. 

Yesterdays high temperature in the Tulsa area was officially 113.  This fell shy of the all time Tulsa record of 115 but did surpass the daily record of 110.  

A weak boundary is located across northern OK this morning and is providing some temporary relief from the usual morning heat as north winds are blowing across the area.  Unfortunately the winds are expected to return from the southwest around midday as the boundary moves northward and this will allow more very hot temperatures to occur across the region.  A few isolated showers or storms will be possible, but just like yesterday, a lot of folks will miss out on the activity. 

The RAW numbers from the NAM indicate highs in Tulsa around 113 again today, but we have lowered the highs to around 108 to 110 for the metro.  Some locations across southeastern OK will have the chance to move back into the 110 to 114 range.  

The mid level ridge has flattened this morning and the center of the ridge is just south of our area.  This has allowed some showers and storms to form across Kansas and extreme northwestern OK.  Its doubtful this activity will move into our area, but a few isolated or scattered storms will be possible today due to the influence of the boundary nearby combined with the very hot afternoon temperatures. 

The heat wave will not be broken this weekend but we're seeing signs in the extended data regarding the position of the mid level ridge by next Thursday and Friday.  The ridge should be located to our west allowing for the favorable northwest flow aloft that will bring a few storm systems into the state.  This mornings the GFS and EURO are both agreeing on a front moving across the area next Wednesday and Thursday with a chance of storms and some not as hot air.  Stay tuned!
