Monday Morning Update

This spectacular early summer weather pattern will remain for most of the week.  The temps will be around 10 degrees below normal for both daytime highs and overnight lows for the next few days before the major upper level synoptic pattern begins to slowly change.  This will allow temps to climb back to near the upper 80s or 90 by the weekend with increasing humidity levels and a slight chance of showers or storms. 

The massive mid-level ridge remains anchored across the western third of the nation, bringing extremely hot conditions across the southwest into the western half of the nation.  The mid-level trough located across the eastern portions of the nation is bringing unseasonably cool readings to a very large portion of the southern, central, and northern plains eastward into the Midwest.  Locations near and to the east of this feature are also receiving some precipitation, but our area, will remain dry for the next few days.  A few very small or isolated showers may be possible across portions of Arkansas or extreme northeastern or eastern OK but almost all locations will remain dry for the week.

By the weekend the mid-level ridge will begin to break down and the eastern trough will weaken.  GFS and EURO data both suggest a mid-level low will develop at the base of the trough allowing for a chance of showers and storms across the southern plains but we do have differences in the data.  GFS takes the low across north TX and eventually moves to western TX by Sunday evening into Monday morning.  The EURO takes the low northward from the TX area across northern OK by Sunday evening into Monday allowing for increasing rain and storm chances by the second half of the weekend into early next week.  At this point, I'm inclined to side with the EURO solution, but frankly the confidence level remains extremely low after Friday.  Stay tuned for updates.

The official high in Tulsa yesterday was 86 from 2:48pm. 

The normal daily average high is 91 and the low is 71.  Daily records include a low of 57 recorded from 1995, 1924, and 1918.  The record high is 106 from 1917.
