FORECAST IN DETAIL


Dry, sometimes windy, but slowly warming. That’s our trend for the upcoming weekend. And that is despite a couple cold fronts darting through D.C. over the next five days. We have more of this ahead in the coming weeks, as the atmosphere transitions from summer to winter, and the jet stream again enters our region. It’s back from its summertime vacation in Canada!

Today (Friday): North-northwesterly winds at 10-20 mph may feel chilly while the sun gets shrouded by a thin veil of clouds at times. You can thank a reinforcing shot of cool air, courtesy of a weak—but fast moving—cold front. One advantage to a daytime frontal passage? High temperatures still manage the low-to-mid 60s, since the day still gets warmed sufficiently by the sun while cooler, drier air slowly filters in. Confidence: High

Tonight: Breezes gradually die down. Ready the heat lamps in the greenhouse. High pressure settles in after sunset tonight, allowing for a quick temperature drop into the low-and-mid 30s to around 40 (downtown) by dawn. Much of our area north and west of the Beltway is under the gun for very chilly or sub-freezing air. Dew points may be low enough that frost is less likely, but it’s always possible. Confidence: Medium

Tomorrow (Saturday): Shows us some moderation by giving us a wind shift from the cooler northerly direction to a more southwesterly flow. This should slowly boost up our temperatures and the water vapor in the air. So, shake off that morning chill as sunny skies easily warm us up to around 62-68, or thereabouts. Please get outside and run, ride that bike, do that rugby game—soak up that UV! It is the season to start storing up that vitamin D3 in your body. Confidence: Medium-High

Tomorrow night: Our southerly breeze may continue and aid in slowing down our dropping temperatures into the evening. Stars are visible earlier in the night rather than later, as a few clouds may move in. This blanket of clouds for a short time before sunrise should help noticeably buoy our temperatures in the milder 40s. Downtown may even hold the 50 degree mark—it is possible! Confidence: Medium

Sunday: Despite us battling clouds more and more as the day wears on (thank you to storm system in the Midwest), a strong southerly breeze could still get us to the 70 degree mark. Upper 60s and even low 70s should cover much of the region. Get out early to enjoy that more dominant sunshine! Confidence: Medium

A LOOK AHEAD

Sunday night: Clouds could quickly increase into fully overcast skies by midnight. Before sunrise we do run a remote (10%) chance of a shower, as temperatures stay very mild with the continued southerly flow—in the mid-to-upper 50s. Confidence: Medium

Rotating towards and through our area on Monday, a cold front stemming from the Midwestern storm system keeps us mostly covered with clouds. Showers could be sporadic throughout much of the day (30-40% chance) so do stuff that small umbrella in your pocket or bag. Silver lining? High temperatures in the 70s! It may even feel a bit muggy, arguably Confidence: Low-Medium

Tuesday may not be so bad, if this cold front proves to dry us out more than cool us down. Comfortable air (without static shock!), mainly sunny skies, and temperatures in the 60s to near 70—not bad, right? Breezes could still remind us, at times, that it is, in fact, autumn. Confidence: Low-Medium
