FORECAST IN DETAIL
Wow, here we are marching into the heart of July with temperatures refusing to breach 90 and dew points almost as low as they can go this time of year (comfortable 50s and 60s). Yesterday afternoon, Ian Livingston mentioned the developing El Niño pattern (citing a Reuters article). For the D.C. area, a developing El Niño tends to equate with relatively cool and wet summers. And so far, that appears to be the case. While we cannot rule out some brief heat spikes (like maybe one this Saturday), the summer continues to be quite pleasant overall.
Today (Tuesday): Mixture of clouds and sun today will keep things less sunny than Monday; but,we can still expect very pleasant temperatures in the middle 80s with low humidity. Light west winds are expected and there is the very slight, slight chance of an isolated shower out there (less than 30%) late this afternoon, especially north of town. Confidence: Medium-High
Tonight: Partly cloudy skies should prevail. Those low humidity levels should allow temperatures to drop back into the 60s in the city and probably upper 50s in the outer suburbs again. Winds should shift to coming from a northerly direction. Confidence: Medium-High
Keep reading for the forecast through the weekend...
Tomorrow (Wednesday): The overnight wind shift should set the stage for a slightly cooler Wednesday with low-to-mid 80s for highs and still partly cloudy skies. Dew points should remain low and again there is an outside chance of an isolated shower or thunderstorm (less than 30%). Confidence: Medium-High
Tomorrow Night: Clouds will be around and lows should drop into the upper 50s to low 60s (warmest in the city). Calm winds or light breezes from the north should be expected again. Confidence: Medium
Thursday could be the coolest day of the week due to more clouds and a prevailing wind flow from the north or northeast. This could also mean more showers (40% chance) or even a thunderstorm. Look for a high temperature range in the upper 70s to low 80s. Confidence: Medium
Friday inches warmer, but we cannot escape that continued 40% chance for showers and possible thunderstorms under partly cloudy skies. Temperatures should return to the middle 80s for highs and look for morning lows again in the upper 50s to low 60s. Confidence: Low-Medium
The weekend could feature a quick burst of stronger heat especially on Saturday as another big cold front approaches the region and forces some heat out ahead of it. We could see upper 80s or even low 90s with slightly higher humidity. Sunday should take a step back with mid-to-upper 80s more likely. Lows should mainly be in the 60s. There will be a 40% chance of thunderstorms both days. So there might be a stronger touch of summer this weekend, but there are no signs it will persist if we get it. Confidence: Low
