Tuesday Morning Update

The system that brought rain to the state will be moving out of the region during the morning to midday hours with gusty north winds and cool air for the afternoon. 

 A cold front is moving southeast across the northern part of the state this morning and will exit far southeastern OK later today.  Morning rain and a few thunderstorms will be likely for the next few hours, but most of the late morning through afternoon time periods will be dry across northern OK and southern Kansas.  A few lingering showers may be possible behind the boundary across the southern sections of the area through the midday time period.  We are not expecting severe weather this morning. There was one severe storm overnight across central OK that produced some winds around 58 to 60 mph.  

Temperatures behind this front will be cool.  Strong northwest winds at 15 to 25 mph will usher dry air across the central plains into Oklahoma setting the stage for some chilly nights and cool afternoons.  Wednesday morning temperatures should drop into the lower or mid 40s across northern OK with highs in the lower 60s.  Mostly sunny conditions will be the call for part of tomorrow, but some clouds will eventually be in the mix by afternoon if not earlier.  

A fast moving upper level wave will move across the state Wednesday night into Thursday morning producing a few light showers or sprinkles in a few locations.  This wave will more than likely traverse the region overnight with little impact for most activities.  Thus, we'll keep only a slight mention in the forecast.  

The extended data in the models leave plenty of doubt and a lack of confidence in the overall weekend outlook.  

 The EURO depicts a significant long wave trough sliding across the country bringing a round of rain and storms back to the southern plains with much colder air for the weekend.  The GFS yesterday had almost no hint of this system and resulted in dry and cool conditions.  This morning I find the GFS is starting to show some signs of the wave.  We'll continue to keep a slight chance of precipitation in the forecast for the Friday night and Saturday morning time frame with a minor cool down for Saturday.  This portion of the 7 day planner may undergo some changes in the next two days regarding temperatures and precip chances.  Please check often for updates.

The high in Tulsa yesterday was 65 recorded at 1:26am.

The normal daily average is 73 and the low is 51.

Daily records include a high of 91 from both 1963 and 1936.  The daily record low is 37 from 2002.

Precipitation yesterday was 0.72 inches at Tulsa International Airport. 

This brings our year to date total to 27.85" which is -5.63 compared to the normal precip to date of 33.48".  

You'll find me on Facebook and Twitter. 

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

Thanks for reading the Tuesday Morning Weather discussion and blog.  

Have a super great day!
