Wednesday Morning Update

We're in store for some nice spring like weather today with highs in the lower 60s before more cold air takes a run at the area Thursday.  Some light drizzle, fog, or brief showers may be possible Thursday, but the chance will remain low for the area.  A few showers or storms may be possible Sunday with an upper level system nearby and a stronger system will be near the state Tuesday or Wednesday of next week with a chance of thunderstorms.  

The afternoon highs should move into the 60s today along with a mostly sunny sky.  Locations to our south could reach the lower 70s.  This quick move into spring like weather will be over for northern OK Thursday as the leading edge of the shallow cold air mass moves southward. 

The data has come into more of a consensus regarding the Thursday front, and this matches up more with past experience regarding these shallow cold air masses.  The front will more than likely arrive late tonight move south of the Tulsa area before stalling along the valleys of southeastern OK. A surface wave will develop on the boundary and cause part of the front to lift northward as a warm front Thursday afternoon.  This will stay well south of the Tulsa vicinity meaning temperatures near Tulsa and northward will remain in the upper 30s or lower 40s while locations south of the warm front could hit the 60s or even the lower 70s.  This warm air zone will more than likely be confined to areas along and south of the Red River Valley.

Thursday evening the front gets a shove and moves southward across the Red River bringing cold air to most of the state.  The moisture will quickly be swept eastward and we'll see cold but dry conditions Friday as the cold air quickly moves eastward.   

A second surge of cold air may arrive Friday night into Saturday but the latest data quickly returns south winds Saturday with highs moving to near 50.   

Sunday will feature a few scattered showers with cloudy conditions and highs in the 50s as south winds attempt to bring low level moisture back to the area. 

The extended data continues to support a strong upper level system nearing the area sometime Tuesday or Wednesday.  The dynamics of the system may support thunderstorms.  Stay tuned! 

The high in Tulsa yesterday was 52 recorded at 4:42pm. 

The normal high is 49 and the normal low is 28.
