Forecast: Sun, low humidity deliver two great days
Weekend back to sultry in a big way
FORECAST IN DETAIL
By David Streit, CWG Meteorologist
The clouds are long gone, and so is the sogginess. Even with warmer than average afternoon readings anticipated today and tomorrow, this is delightful summer weather. All good things come to an end much too soon with humidity levels starting their ascent Saturday morning as a warm front moves through. The passage of this front sets the stage for a 3-H weekend (you know: hazy, hot and humid)! With lots of instability in the air, thunderstorms could pop late in the day and into the evening both weekend days.
Today (Thursday): Winds from the west at 10 to 15 mph bring in much drier air with plenty of sun. Temperatures zip upward from 70s early morning to peak in mid-to-upper 80s. Confidence: High
Keep reading for the forecast through Monday....
Tomorrow (Friday): Tomorrow competes with Tuesday for the best day of the week. Sunshine teams up low humidity for a great day to be out and about. Highs reach the low-to-mid 80s with only a very modest breeze. Confidence: High
Tomorrow Night: This is the perfect evening for outdoor anything! Clear, calm, dry and evening readings in the 70s make a great way to toast in the weekend. Confidence: High
Saturday is a jolt back to the humid conditions so characteristic of Washington summers. A morning warm front brings a 20% chance of showers. The afternoon should be dry with just some scattered high and then mid-level clouds. Highs push into the mid-to-upper 80s by early afternoon before the clouds stabilize readings a little. Thundershowers are possible by evening (40% probability), a few of which could be strong. Confidence: Medium
Sunday gets off to a cloudy and muggy start, with 70s in most spots. As more sunshine emerges, temperatures quickly climb. This should result in highs peaking in the upper 80s to lower 90s. Only a breeze from the west and southwest moderates the sticky air. As a cold front in the Ohio Valley edges closer, thunderstorms in the late afternoon and evening are a 40% possibility. Confidence: Medium
Monday holds the most potential for a forecast bust! A strong cold front just north of the area should stay put. The result is more heat and humidity for the day. Light winds are expected. Highs should make it to the upper 80s in most areas. However, if the front comes through sooner than forecast, readings could be a whopping 10 degrees cooler! Confidence: Low-Medium
