Today will be the last day with 850MB Temps below 16C till about Jul 24/25th where most days between 7/16 - 7/24 will see 850 temps 18-22C, peaking next weekend at 23-24C.
Wed/Thu (7/17-18) : I still think the timing of the remnants of Barry, even if very limited, limit high temp maxes Wed/Thu with clouds coming in Wed PM and lingering part of or most of Thu. These things always come in ahead of models. Despite the clouds temps should still make 90 in most places and DTemps will push into the mid to upper 70s so quite oppressive even if maxes are cut short from clouds.
Fri - Mon (7/19-22) : the heat is on and possible some records during the hottest time of the year, although most of these, especially 2011 look safe but time will tell.
