A Nice Friday

After a cool morning in the 30s and 40s, expect highs in the lower 60s with mostly sunny conditions and light winds.

The upper level system is pulling away from the region this morning and the clouds have started to clear the area from the northwest to southeast.  This has allowed the temps to drop into the upper 30s during the past few hours. Some patchy frost will be possible in these areas of extreme northeastern OK, but not in the immediate Tulsa metro.  

The readings later today should move into the lower or mid 60s along with sunny sky and light northwest winds circulating around a surface ridge of  high pressure located across central OK.

 The weekend also looks very nice with sunny skies, south winds, and mild air.  Morning lows will be in the 30s and 40s with afternoon highs in the upper 60s.  A weak boundary will slide southward Sunday as an upper level system brushes the Missouri Valley.  This boundary will bring a weak wind shift Sunday but no rain is expected.  I will remind you the EURO a few days ago was bringing a chance of rain Sunday and Monday, but yesterday and today the EURO is more progressive with the upper pattern and keeps the system to our east. 

A minor warming trend will commence early next week with highs moving into the lower or mid 70s along with gusty south winds.  The pattern would support another storm system approaching the area late next week with a chance of thunderstorms followed by another cool down.  Stay tuned on this system. 

 The GFS and EURO are once again worlds apart regarding the mid week system.

The EURO is a day late (Thursday) compared to the GFS (Wednesday) and the EURO is once again attempting to close off the upper level low while the GFS is more open and progressive.  The forecast will lean more toward the progressive system.
