80 / 64 very warm and turning hot. Low mid 90s with warmer spots to 95 or above on the warm southwest flow with a skirt of 850 mb temps >18c. Similar Thu (7/13) but humidity builds and isolated or scattered evening storms. By Fri (7/14) it remains very warm and humid with more widespread storms. Where and when the sun is out it will warm up quickly and some areas can extend the heatwave. Sat (7/15) and Sun (7/16) warm and humid with continued storm chances. Some storms especially Fri can be soaker and slow movers. Where and when the sun is out it will heat up quickly with lots o upper 80s / low 90s Mon (7/17) and beyond. Overall warm to hot with continued storm chances. Western Rockies RIdge will send splashes of the strong heat near or into the region for short stints but overall remaining hotter as the western atlantic ridge bumps west keeping the flow warm and humid with the trough into the GL/NE. Looks like a 2-3 day cool to near/normal in the 21-22 timeframe before next sruge of heat is spreading north and east out of the west.

70 / 61 and partly to mostly sunny. Warm one on tap as we move into the seasons first sustained heatwave and overall warm to hot period. Upper 80s to low 90s for those that start the heatwave today. Very isolated storms if any later this evening (doubt any, although one did pop last night into NW NJ). Wed (7/12) stronger heat into the area with low to mid 90s. By Thu (7/13) even stronger heat pushing up on s/sw flow 850 MB temps >18c with humidity and isolated storms chances. Some mid to even perhaps upper 90s in spots. Fri (7/14) higher humidity and continued hot more scattered storms (potentil soakers) with more clouds around (ala last holiday weekend). Where and when the sun is out it heats up rapidly under >16-18C 850 mb temps, Sat (7/15) and beyond - overall warm to hot and humid with storms chances. The western atlantic ridge is epanding to edge the east coast while the western rockies ridge balloons trough remains into the GL. The east stays warm to hot as the stronger heat is nearby and skirts the area with storms chances. Way beyond perhaps trough moves in and out quickly towards the 24 and the western heat poised to blast east.

By the weekend trough pushes against the building Western Atlantic Ridge which is also linking into the southeast ridge and with it comes more humidity and storms chances. Where and when the sun is out it warms quickly so more 90s chances. Sun (7/16) and beyond overall warm to hot with stronger heat skirting the area and overspreading at times. Continued storm chances as well. Stong heat signal 7/17-7/18.
