After some showers Tuesday night..warm week followed by heat for the weekend?..how long though?

Everybody has the holiday weekend on their minds..we all would like typical 4th weather..sunny and hot..well this morning Euro agrees..the weekend will be Sunny hoy and humid..with 90's..Sunday 0z 850 temps
                                                                       
                                                                    

and continues into the 4th


However GFS this morning totally different..I mean totally..big Upper low in eastern Canada

                                                            
                                                                            
However GFS does heat things up Saturday into part of Sunday..but it is very brief


With the Euro model it becomes an old fashioned heatwave..hot thru day 10!
