Monday Morning Update

A few showers and storms formed overnight across portions of northern OK, but most folks across the northeastern part of the state missed out on the activity.  We did have a few brief showers in the Tulsa metro, but most of the activity is now located to our west or southwest and is moving to the southeast.  This morning shower and storm activity will not last long, but later today a few additional showers or storms may develop across far western OK.  The Tulsa metro will be too far east to experience these showers and storms.

Temperatures today will be near or slightly below normal with highs around 79.   Dry air will continue to filter into northeastern OK later tonight and this will allow temperatures to drop into the upper 40s and lower 50s tomorrow morning. 

Some of the operational models indicate some up slope flow storms will be possible tomorrow and Wednesday across far western OK.  The chance will be slim, but even if they do form, they will be too far west to have an impact on our region.

The upper air pattern will support a fast return of south winds and warmer air by the middle of the week.  We'll see temperatures moving back into the lower 70s for morning lows and daytime highs in the lower 90s Thursday through the weekend.

The data supports a front nearing the region by Thursday into the weekend but most data keeps the boundary and the upper air support to far north to impact our area with a big chance of storms.  I considered adding a chance of showers and storms to the Sunday and Monday time periods of next week, but will hold off for another day before approaching this period.  The upper air pattern would suggest the chance, but most of the operational models keep the precipitation to our west or north.
