No Relief Yet

The heat headlines continue to be cranked out on a daily basis, but the forecast does have some minor changes that could bring some relief to a few folks over the next few days.

 The first issue is a tropical disturbance in the Yucatan peninsula area.  This system is on a favorable track into the southwestern Gulf of Mexico and could eject onto the south Texas coastal region tomorrow.  This trajectory and official forecast from the National Hurricane Center takes the system across south Texas, but some increase of low level moisture is possible across eastern or far southeastern OK Saturday. 

 A second feature will be a weak frontal boundary that is expected to drop down from the central plains into northern OK by Friday night.  The NAM is continuing to offer good support for this boundary to light up with a line of thunderstorm activity.  The mid level ridge is not expected to totally move from the region, but the positioning and strength will change just enough to give us some hope of a few scattered showers and storms due to the proximity of this boundary.  I'll keep the previous pops of 20% for Friday and a 30% pop for Saturday with an isolated mention for the Sunday period.

 The temperatures are expected to be very hot today with highs near 107 in the Tulsa metro.  A few more clouds will be in the mix tomorrow and more so Saturday.  This may allow the temps to drop around the 99 degree mark for highs Saturday.  Dick lowered the high for Saturday to 99 and I'll keep it on the map at this point.

 The overnight lows are also expected to remain in the upper 70s and lower 80s. 

 The EURO 850 temps move into the 25C range next week across eastern OK with the northwestern part of the state approaching 30C.  This translates to another week of very hot air with highs from 103 to 110 likely next week across the state.
