Wednesday Morning Update

I'll keep the discussion-blog on the " short side" with a few of the highlights for the next few days.

The weather appears very nice today with mostly sunny conditions and highs in the mid-70s.  A cold front arrives Thanksgiving evening bringing a chance for showers or storms and cooler air Friday into the weekend.  

I think yesterday may have been the best weather day of the week!  We experienced highs in the lower 70s with perfectly blue sky and virtually no wind.  All of this in late November.  The forecast today will feature more warm air. But a few more high clouds late this afternoon combined with a southerly breeze at 10 to 15 mph would still keep the "best day of the week" award reserved for Tuesday! 

The pattern appears to be changing soon which will allow a surface cold front to slide across the area Thursday afternoon and evening with a few showers and storms.  Cooler air will follow with temps Friday in the upper 50s and Saturdays highs in the upper 50s.  Temps in the 850 levels appear to be relatively warm. A surface ridge of high pressure will be positioned near NE OK late Friday night into the first part of Saturday allowing for temps in the mid to upper 20s Saturday morning.  This surface ridge will quickly move eastward allowing south winds to return Saturday evening into Sunday.  

A more significant cold front will arrive late Monday bringing highs down into the upper 40s for Tuesday after morning lows in the lower to upper 20s to lower 30s.  There will be a chance for some showers Monday afternoon into the evening hours, but the precipitation should be south or east of the area before the air mass becomes cold enough to support any frozen precipitation.  The latest model data continues to support the surface low sliding from NW Ok into the Red River Valley with the boundary sliding across the area Monday evening.   The air mass would move eastward and modify but temps next week would remain closer to the seasonal average compared to the warm air we've been experiencing this past week. EURO data suggest another fast moving cold front could approach late next week. 

 

Our high yesterday was 73 recorded at 3:29pm.

The normal average high is 58 with the low of 37.

Daily records include a high of 79 from 1927 and a low of 18 from 1964.

 

Thanks for reading the Wednesday morning discussion-blog.
