A few showers and storms will continue for the next few hours across northern OK and southern Kansas as an outflow boundary sinks southward and the low level jet pumps moisture into this area.  A few storms will produce some small hail and gusty winds, but these are not expected to be severe.  After this morning, we expect a mainly sunny afternoon with highs in the mid 90s.  Triple digit weather will be likely across the western half of the state. This trend of late night and early morning storm chances will continue for the next several days. 

 As stated yesterday, the models have been horrible, but the NAM may be coming around to some credence.  It will bring a surface trough into the area Saturday evening with another chance of storms Saturday night into pre-dawn Sunday morning.  I don't expect the MCS's to move too far south, but there will be a window late Saturday night into Sunday morning for storms to move into the northern tier counties of the state.

This trough will then mix out or move northward keeping the Sunday and Monday periods in the hot air.  Gusty south winds around 15 to 30 mph will be common this weekend with highs in the upper 90s across eastern OK.

 

The mid level ridge will totally be suppressed southward by Tuesday as several upper level troughs move across the nation.  This will bring a front into the state Tuesday night into Wednesday with a chance of showers and storms.  The afternoon highs will be dropping to near normal or even below normal during this period with morning lows in the 60s.
