Good Morning!

We're looking at very cool air across northern OK and southern Kansas this morning with readings into the upper 30s and lower 40s.  It's possible that some locations may receive a little frost in a few valley areas.  The winds will not be as strong today compared to the previous few, but northwest winds from 10 to 15 mph will be likely along with sunshine and highs in the mid or upper 60s.  The pattern is slowly changing and our major upper level system over the Midwest continues to lift northeast into Canada.  This will signal an "end" to the current "cool spell" with much warmer air arriving this weekend.

The upper air pattern from the northwest will undergo a change Friday into the weekend.  A trough will brush the area this evening and exit the region Friday morning.  The result will be warming temps Friday with highs in the mid-70s after a cool start in the upper 30s and lower 40s.  The winds will be light Friday with west or northwest winds around 10 mph.  Friday may be the best weather day of the week.

This weekend features warmer air with morning lows moving Saturday into the upper 40s and Sunday into the upper 50s.  Saturday afternoon highs in the mid-80s seem likely with Sundays temps closer to the upper 80s.  The pressure gradient will increase Sunday and stronger south winds will return in the 15 to 30 mph range by midday to afternoon.

Next week will feature yet another upper level pattern change, but this time, the end result will be increasing storm chances by the middle to end of the week. Southerly surface flow will reside this weekend into all of next week.  A digging trough in the west will eventually allow moisture currently suppressed in the Gulf to stream northward.  GFS data support improving surface trajectories and increasing 60 dews into our area by Tuesday into Wednesday.      A southwest flow aloft pattern will bring a few disturbances across the area late next week and the storm chances will be increasing.  Obviously we're too far out to pin point specifics, but the "pattern" would suggest a return to some stormy weather by the end of the week.   EURO data support a few storms off a quasi-dry line feature Tuesday and Wednesday that would remain to our west.  Regardless, we'll be eventually introducing some pops for these time period in the big extended forecast.

Our daily high yesterday was 61 from 2:55pm.

Daily records today include a high of 91 from 2002 and a low of 32 from 1909.

The normal daily average high is 76 and the low is 55.

You'll find me on Facebook and Twitter.

I'll also be discussing the forecast on numerous Radio Oklahoma News Network affiliates across the state through the morning hours.  Additionally, you'll hear our forecast locally on numerous Clear Channel Radio stations in Tulsa including KMOD, The Buzz, The Beat, and The Twister.


Thanks for reading the Thursday Morning Weather discussion and blog.


Have a super great day!
