On the satellite picture this AM we see the heat ridge is centered over the Mississippi River valley still and its effects spread from the desert SW to the NE US as it expands.
The heat just coninues to be relentless over MUCH of the US and another day with widespread 100+ degree heat from the southrn plains to the SE coast and 90s for the forecast area
There are pesky disturbances riding the edge of the heat ridge and we are on the edge of the heat ridge so some isolated showers and storms will be possible this afternoon. I don’t expect anything widespread but with any disturbance moving into this kind of heat , some isolated storms are very possible.
Other than that today will be sunny and very hot with highs in the upper 80s over NE PA to low to mid 90s for the rest, with a little added humidity heat indexes in the upper 90s to low 100s expected. DC through the SE US will see widespread 100-108 degree highs. Lows tonight again will only fall into the upper 60s to mid 70s
Monday and Tuesday will be similar, highs in the mid to upper 80s over NE PA to low to mid 90s for the rest , with maybe an isolated storm in the afternoon, humidity wont be too high so heat indexes will remain near the temperature lows in the mid 60s NE PA to low to mid 70s elsewhere
For the 4th of July holiday (Wednesday) hot weather continues BUT there could be some trouble and mother nature could make her own firework show
Late Tuesday into Wednesday stronger disturbances will ride along the north side of the ridge, and with a hot humid air mass place , I expect thunderstorms to be more widespread on Wednesday, not really widespread but lets call it scattered thunderstorms which have potential to be strong and could put a damper on any BBQ’s or parties and even firework shows .
Image for Wednesday evening is above and there’s scattered showers and storms out and about with passing disturbances, again with the hot humid air in place these could be strong storms.
Thursday through the Weekend I expect the same overall pattern of hot humid weather with mid level disturbances coming through with isolated to scattered storms every afternoon and highs in the mid 80s to low 90s going through what will be a holiday weekend for many. Overall it should be a pretty nice summer weekend just watch out for some storms every afternoon.
