Wednesday Morning Update

The chilly air mass will remain for the next 25 to 36 hours before we see a pattern change for the weekend.  We'll go from highs near 60 today, Thursday morning lows in the upper 30s, and weekend highs in the mid to upper 80s.  I think we're about 7 to 9 days away from our next big weather maker that could also support another episode of spring thunderstorms.  

We experienced a few spotty showers yesterday across southern Kansas and northern OK but most folks remained dry.  The clouds will attempt to thin out later this morning with afternoon highs nearing 60 to 63 with northwest winds around 10 to 20 mph.  This means most of the day will be spent in the upper 50s for most of the northern OK and southern Kansas vicinity before breaking around 60 by afternoon.  Grab a jacket.

 A trough will move across the region Thursday night into Friday and this will signal a pattern change for the weekend into early next week.  The upper air flow will transition from the current northwest flow to more of a west to east movement for the weekend.  The result will be warmer temps, lighter winds Friday and Saturday, and no storms for the weekend. Weekend numbers should rise with Saturday morning lows in the upper 40s and lower 50s with highs in the mid-80s.  Sunday morning could start in the upper 50s and finish the upper 80 with strong south winds.  

Next week the upper air pattern will undergo yet another change.  Most data support a deep southwest flow developing by the Tuesday to Thursday period.  The result will be another surface area of low pressure forming near NW Oklahoma during the Monday period and migrating northward Wednesday or Thursday period with increasing southerly flow.  I anticipate trajectories supportive of low level moisture transport into the southern and central plains setting the stage for thunderstorm development as early as Wednesday into Thursday.  By Thursday and Friday, the "pattern" would be supportive of more strong to severe storms across the state.   

The official high in Tulsa yesterday was 58 at 12:46am. 

The normal daily average high is 76 and the low is 54.

Our daily records include a high of 91 from both 1987 and 1959.  Our daily record low is 35 from 1968. 

You'll find me on Facebook and Twitter.  

I'll also be on a number of Radio Oklahoma News Network affiliates across the state.  And You'll hear me on several Tulsa Clear Channel Radio stations, including KMOD, The Twister, The Beat, and The Buzz. 

Thanks for reading the Wednesday Morning Weather discussion and blog.

Have a super great day.
