Thursday Morning Update

No major change is anticipated regarding our above average daytime highs for the next few days with many locations topping out in the upper 80s.  The pressure gradient will become stronger tomorrow into the weekend and southerly surface winds will increase speeds into the 15 to 30 mph range Friday and Saturday.  This will occur as a storm system begins drawing closer to the region.  This system will also increase our storm chances for Sunday into Monday as a weak cold front moves across the state.  A few isolated storms are a possibility Friday and Saturday to our west as a weak mid-level disturbance moves eastward before weakening Saturday morning.  I have not included these 10% pops for the Friday and Saturday period, but a few isolated storms are possible near the I-35 area Friday and Saturday.

Saturday afternoon and evening the boundary will approach northwestern OK and a narrow area of thunderstorms will form, some of which may become severe.  The boundary will be entering our area Sunday bringing a round of showers or storms to part of the area Sunday evening into Monday.  The latest data indicates the better window for storms for most of the northeastern and eastern third of the state will take place Sunday evening trough Monday morning. 

This boundary will begin to slow down Monday, stall across southern OK, and then move back northward wither Tuesday or Wednesday.  The EURO seems to suggest the boundary may not return northward until Wednesday morning with a round of storms along the warm front.  The GFS brings the return flow back Tuesday with no storms. 

I think the pattern will begin to change by the middle of next week and this may allow for a typically strong May system to move closer to the area late next week or during the Memorial Day Holiday weekend.
