Despite the Heat Advisory issued for parts of the area today, what the D.C. area ended up with is a fairly normal hot July day with highs from near 90 to the mid-90s and the heat index in the 90s to near 100. It’s one of the few days this summer that the heat has actually underachieved. Like yesterday, we’re on the look out for some showers and storms into this evening.
Through Tonight: Shower and storm chances range from about 30% north of town to 50-60% from D.C. to the south. Not only is the best chance of storms across southern parts of the area, but that’s also where any storms are likely to be strongest, potentially with strong winds and maybe some hail. Muggy air sticks around through the night with lows mainly in the 70s.
The Weekend: Saturday shapes up a lot like today with highs from near 90 to the mid-90s. Shower and storm chances hang around as well, to the tune of about 40%. Hard to pinpoint timing as of now. Sunday should finally see shower/storm chances fall to 20% or less as highs reach near 90 to the low 90s under partly to mostly sunny skies. Both days should feature humidity levels a touch lower than the past few.
Pollen update:.Grass, tree and weed pollen are currently in the LOW range (though grass levels are considered MODERATE for our local area). Mold spores are in the MODERATE range.
