Friday Morning Update

Some light patchy fog is possible in a few of the valleys this morning.  Otherwise expect a sunny and mild afternoon with highs in the lower to mid-70s.  A few storms are still possible Easter Sunday into Monday.  

We saw a few showers and sprinkles last night, but most folks remained dry.  We're looking at decreasing clouds, mild weather, and highs in the lower to mid-70s this afternoon.  Saturday will feature mostly sunny to partly cloudy conditions and highs nearing 80.  Easter Sunday still offers scattered thunderstorms and highs in the lower 70s. The timing now supports mainly Sunday evening into Monday morning activity, but this timing could still change again!  

The main upper air pattern will bring another wave across the state Saturday night into Sunday.  This wave does not appear to be strong, but a few storms could become strong to severe Sunday due to increasing moisture and some surface instability.  Model dew point temps are still suggestive of the upper 50s to lower 60s by Sunday afternoon.  A surface low will be west of the area along with a dry line type feature across western OK by Sunday afternoon.  A surface cold front will move into the area sometime Monday bringing a respite with dry air back to the area Monday afternoon and Tuesday. This morning's data suggest the Sunday activity should be scattered and mainly across western OK during most of the day Sunday before slowly advancing eastward Sunday night into Monday morning.  We've lowered our chances from previous forecast to about a 50-50 shot for Sunday into Monday morning.  The chance may need to be lowered slightly for Sunday and brought slightly higher for Monday morning, but we may keep the pop structure at 50-50 for another run or two of data.   

Tuesday into late next week southerly flow will commence with increasing low level moisture.  Most data, and the pattern, will suggest a strong storm system will near the area late next week with increasing storm chances.  We may see additional storms Thursday or Friday, and some of these would probably be severe.  The "best" timing at this point would occur Thursday late into Friday.  

In summary, expect a nice "good Friday" with light east to southeast winds and highs in the lower to mid-70s.   

The official high yesterday in Tulsa was 63 recorded at 12:45pm.

The normal daily average high is 73 and the low is 50.

Our daily records include a high of 98 from 1925 and a low of 29 from 1953. 

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. 

You'll also hear the forecast on a number of Clear Channel Radio Stations in the Tulsa metro, including KMOD and The Twister.  

Have a super great day!

And a wonderful Easter.
