500mb Jet Stream Chart above.
Hotter than normal temperatures the next 4 days as the heat wave continues this week with temps running 4-9 degrees above average.
Then temperatures drop a bit as the cloud cover increases by the weekend and beyond and the number of showers and thunderstorms increases on the weekend and next week.
Meanwhile the next three days its hazy hot and humid with scattered puffy cumulus clouds developing in the afternoon, the chance of a late afternoon or evening thunderstorm is only 20% or less (”silent POP”) not enough to put in my formal forecast or cancel plans over... just know rain chance is NOT zero and when thunder roars go indoors.
The heat and humidity continue Thursday the 4th of July right into next week but with more clouds and a 30-50% chance of a shower or thunderstorm afternoon and evening with the main “window of risk” sometime between 2pm and 10pm.
Remember, the “Heat Index” or “Feels Like” is measured in the shade, add up to 15F for direct sunlight. Stay hydrated.
