Sunday - pending on the extent of clouds and storms will fall below or continue the heatwave (7,6,5th) day. Mon - Tue loo very unsettles and could yield a fairly onshore miserable mis summers day with >1.00 - 2.00 of rain. Clear out by Wed, with a much warmer THu/Fri potential 90s in the hotter areas. Overall huge ridge builds out west expands into the plains 7/7 - 7/14 and heat expands east for an overall warmer 7/15 - beyond. 7/3 - 7/4 : High heat isolated storms at PM 7/5 - 7/7 : Storms - rain >1.00- 2.00 onshore flow could keep Mon/Tue very cool 7/8 - 7/10: Warmer near - above normal - hot areas 90s 7/11 - 7/14 : Below normal 7/15 - Beyond: Moderation to / above normal next shot at stronger heat towards the last 10 days of Jul
