Wednesday Morning Update

Wednesday, August 6th 2014, 4:29 am

Good morning. This is the day we start to slowly see a minor pattern change that will result in a chance for a few showers or storms. The mid-level ridge of high pressure near the region today will slowly slide westward and flatten. This will allow a weak disturbance currently west of the region to move nearby later this afternoon and tonight. A few showers or storms will develop near northwestern OK this morning and may move into our area this afternoon into the evening. Our chances will remain very low today, but I will keep a mention in the forecast for this afternoon and evening.

The data support a continued chance for scattered showers and storms almost every day in the extended forecast across the northern third of the state into southeastern Kansas. The upper flow will allow a weak boundary currently across the central plains states to move southward by the end of the weekend and this will also bring a few showers and storms to the region. This boundary will more than likely not cross the Tulsa region until possibly Monday. Temperatures before this boundary arrives will continue to remain near and above the seasonal average with readings early next week dropping a few degrees.

The threat for severe storms will remain low but not zero. A few of the storms during the late afternoon and early evening time periods could produce some quick damaging wind down-bursts.

The temperatures for the last few days have slowly increased day by day. And we anticipate this will be the case today and tomorrow despite the chance for a few showers or storms in a few locations. The temperature heat index values may also slowly increase with readings today a few degrees off the surface temps. By the end of the week, we may see some THI values.

The official high in Tulsa yesterday was 92 recorded at 2:46pm. The normal average high is 94 and the low is 73. Daily records include a high of 109 from 2011 and 1956. The daily record low is 60 from both 1997 and 1920.

You'll find me on Facebook and Twitter.

I'll be discussing the weather on numerous Radio Oklahoma News network affiliates across the state through the morning hours.

You'll also hear our forecast on Tulsa metro radio stations, including KMOD, The Twister, The Beat, and The buzz. These stations are part of Clear Channel Communications.

Thanks for reading the Tuesday Morning weather discussion and blog.

Have a super great and safe day!
