Tuesday Morning Update

A few isolated strong storms developed late last night across Osage county producing 2 to 3 inch rainfall along with some localized flooding issues.  At this moment ( 330am) we have no showers or storms on the radar across the area.    

Our weather today will be dominated by a rich low level moisture field and warmer temps in the lower and mid-levels of the atmosphere.  This will result in high temperatures in the lower 90s with heat index values in the mid to upper 90s.  Our local dew points are currently in the lower to mid-70s.   South winds will be in the 10 to 25 mph range today and tomorrow.  

A surface ridge of high pressure located across part of southwest Texas will nudge northward today keeping the state void of precip (after the early morning hours).  A surface boundary across Kansas this morning will quickly lift northward and become positioned across the central plains this afternoon and evening.  Severe weather is likely across these areas of the nation this afternoon and tonight.  Another complex of storms will likely develop tonight across central Kansas but should remain well north of our state. 

Wednesday this boundary will move southward in response to an approaching upper level short wave across the intermountain west.  This boundary may enter northern OK Wednesday night into Thursday morning with a slight chance of isolated storms near and north of the boundary.  The NAM brings the boundary into the state, while other data keeps this feature draped across southern Kansas. Close call.  We'll keep the boundary slightly north of Tulsa, but will include chances for thunderstorms late Wednesday night into Thursday morning.  Then another chance for a few storms Thursday across the northern third of the state into southern Kansas.  

Thursday through Friday this boundary will be near the northern OK and southern Kansas vicinity allowing for unsettled weather, including the chance of scattered severe thunderstorms producing some severe weather and heavy rainfall.  

By the weekend, the boundary may slowly lift northward Saturday before being shoved southward Sunday with additional showers and thunderstorms.  The air mass behind the boundary will bring our temperatures closer to seasonal averages early next week, at least for Monday and Tuesday.  

The official high in Tulsa yesterday was 86 recorded at 3:41pm.

The normal daily average high is 84 and the low is 64.

Our daily records include a high of 101 from 1911.  The daily record low is 52 from 2013, 1946, and 1922.

Yesterday's rainfall in Tulsa was 1.53 inches at Tulsa International. This brings the year to date total to 9.98 which is -6.89 inches below the normal precip to date.  

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!
