Have layers available over the next few days, since the weather will often change notably from one to the next. We’ve got sun and crisp breezes today, and increasingly cloudy skies tomorrow but also mild winds. Then by Sunday it looks bright and blustery! There could be some rain in the middle. Ahh, fall.
Today (Friday): Sunshine should dominate, but moderate northwesterly breezes around 10 mph add some chill, particularly in the morning hours. High temperatures dip back below average, getting near 50 to lower 50s. Confidence: Medium-High
Tonight: Clouds may increase in the early morning, but some stars should shine before then. Breezes should be steady, around 5 mph out of the south and southwest. Low temperatures downtown may hover in the low 40s, with some mid-30s possible outside of the Beltway. Confidence: Medium-High
Tomorrow (Saturday): Very cloudy conditions are probable, with a slight chance of a quick late-afternoon shower. High temperatures are boosted into the mid-50s to perhaps low 60s, thanks to southerly winds increasing to around 15 mph. Some gusts near 25 mph can’t be ruled out. Confidence: Medium
Tomorrow night: Wind may continue to blow between 15 and 25 mph, but shifting direction overnight. Ahead of the cold front, southerly flow dominates. Behind it, into the early morning hours, the blustery conditions turn around to blow from the west-northwesterly direction. Showers are likely during the middle of the night, with perhaps a couple moderately rainy moments around midnight — but total rain amounts may stay below a quarter of an inch. Low temperatures don’t get much of a chance to fall before sunrise, bottoming out in the mid-to-upper 40s. Confidence: Medium
Sunday: Wind around 20 to 35 mph at times may be the main story. Blustery west-northwesterly conditions really reinforce wintry conditions behind this cold front. Temperatures in the morning hours may prove the high temperatures of the day, in the upper 40s to low 50s, before falling a few degrees in the afternoon. Wind chills could be around 10 degrees lower than air temperature reads on any thermometer. At least any sunrise sprinkles move out quickly, with sun dominating the day. Confidence: Medium
Sunday night: A cold and still-breezy night appears likely. Even the warmer downtown area is eying the freezing mark as a low temperature near dawn. Most of the region should see upper 20s to around 30 degrees. Confidence: Medium
It appears now that slightly calmer, sunnier conditions are possible Monday and Tuesday. However, this doesn’t rule out a moderate breeze or a few clouds at times. Temperatures should be able to get near 50 Monday and into the 50s Tuesday. Slight wind chills could shave off a few degrees of comfort from those temperatures. Stay tuned for tweaks to the forecast as we get closer. Confidence: Medium
