Friday Morning Update

Some patchy but dense fog is possible this morning but we expect a mix of sun and clouds today with highs in the lower 80s.  Windy and warm conditions are likely this weekend with a slight chance of isolated storms Saturday. Higher chances, including the threat of severe weather, will remain for Sunday into early next week.   

We've made it to the weekend but a major storm system will be approaching the southern and central plains providing a chance for severe weather across a large portion of the plains states, including part of Oklahoma. All modes of severe weather will be possible including large hail, damaging winds, and possibly tornadoes.  The main window for severe weather for our immediate area will begin Sunday and may not end until early Tuesday morning.  This does not mean storms will be likely during this entire time period, but the chance for thunderstorm development will be increasing during these periods. 

A major upper level trough will move slowly eastward to near the four corners area by late this weekend.  Strong winds aloft will overspread the state by Sunday into Monday.  A surface dry line will be positioned across western OK Friday through the weekend.  A dry line separates warm and moist air from dry and hot air.  Locations east of the dry line today and tomorrow will have a chance of isolated storm development, but most if not all of the storms will reside well west of our areas.  

This dry line will move eastward during the day Sunday and may be positioned near or just west of the I-35 corridor by Sunday afternoon.  Severe storms will attempt to form Sunday afternoon and evening near the vicinity of this feature and move northeast into part of northern OK and southern Kansas.  These storms will eventually move east or northeast away from the area by pre-dawn Monday, but the main upper level system will reside to our west allowing for another round of thunderstorms Monday afternoon and evening as a surface cold front approaches the state.  Some of these storms Monday afternoon and evening will also have the chance to be severe before the boundary passes the area sometime early Tuesday morning.  EURO data brings the boundary through the area Tuesday morning, but GFS data stalls the boundary and lifts it northward as a quasi-warm front Wednesday and Thursday.  The GFS suggestion would bring another round of strong to severe storms into the region by late next week while the EURO would bring a minor cool down Tuesday into Wednesday before a small chance of storms arrive by next Friday.   

The high in Tulsa yesterday was 73 recorded at 2:55pm.

The normal daily average high is 80 and the low is 60.

Our daily record high is 94 from 1911 and the low is 40 from 1945.

You'll hear my forecast on numerous Radio Oklahoma News Network Affiliate stations throughout the state this morning. 

I'll also be discussing our weather with Dan Potter and The KRMG Morning News.
