A sizzling sandwich of summer looks to be served up for Saturday and Sunday. High temperatures in the 90s and increasing humidity should remind us that the last few days are somewhat atypical of D.C. in the summer. The bread of this sandwich — on either side of the two main weekend days — features relatively more decent days, both Friday (near 90) and for fireworks on Monday (around 90). Any dashes away from work today, or local travel, should be met with dry conditions. Just don’t forget to be back at work Tuesday!
Today (Friday): Take in that last bit of dry, light north-northwesterly breeze that’s keeping us unusually comfortable. Despite some hot highs near 90 today, heat indices may feel lower! Generously lather-up that sunscreen since only a few clouds could dot the clear sky, offering little to no protection from extreme UV during summer’s peak sun. If driving eastward toward the beach, have at it. Great weather conditions! Confidence: High
Tonight: If anyone is left downtown, I may see you outside, mid-city somewhere too hot to dine outside after this evening, enjoying dinner. Mainly clear skies allow for some decent overnight cooling. Dinnertime readings should slowly slip into and through the 70s, with pre-dawn downtown temps bottoming in the mid-to-upper 60s. Outside the Beltway should have some readings perhaps as low as 60. Confidence: High
Keep reading for the forecast through the 4th of July weekend and into next week...
Tomorrow (Saturday): Summer returns. Dew points climb back into a range of “slightly sticky” (near 60) along with temperatures topping out near 90 to the mid-90s. With mostly sunny skies and perhaps a few clouds, I am already seeking shade in my mind, oof. Confidence: Medium-High
Tomorrow night: Skies could cloud up just a bit cloudier as a weak cold front tries to slowly approach and wash out a bit. I can’t rule out a shower or two, especially D.C. and north, though the main action looks to be north of the area. Low temperatures should hover in a warm range of upper 60s to lower 70s, region-wide. Confidence: Medium
Sunday: We get some shade from above, in the form of periodic clouds thanks to that weak cold front. What is unfortunate is that there is only a 30% chance of showers or storms to relieve our dry spell. It may be that the frontal passage is mostly unnoticed, except for winds shifting to the west and northwest. Before any “cooler” air filters in, that could set the stage for highs in the mid-90s or even above thanks to downsloping. Take it easy with lots of water please. Confidence: Medium
Sunday night: The front doesn’t move far, so it’s still warm with low temperatures staying mostly in the 70s for almost everyone -- a few spots could see upper 60s if lucky. I am looking at you Fredericksburg, Hagerstown, & Winchester! I can’t rule out a continued chance of a shower through the night. Confidence: Medium
A classic D.C. 4th seems to be on tap for Monday. Ok maybe not as sweaty as some years past, but still warm and toasty. Temperatures around 90 or into the low 90s seem a good bet. A bit of humidity too, but perhaps less than Sunday. We’ll have to watch the progress of that front. If it hangs too close, showers and storms may be possible and could keep temperatures down a bit, but I’m leaning on the drier side for now (fingers crossed for this day). A light breeze may actually keep smoke from collecting around the fireworks launch location, as it does often. Hope you have your spot staked out! Enjoy (but with sunscreen ‘til 5-6 p.m. please!). Confidence: Medium
After morning low temperatures in the 60s, we should enjoy more clear skies and, unfortunately, dry weather on Tuesday. High temperatures and humidity conditions could be similar to Monday, with highs eyeing the 90-degree-mark. Hopefully falling a couple degrees shy, instead of surpassing it! Confidence: Medium
