Forecast: Two More Days of Enjoyable Eighties

By Jason Samenow

EXPRESS FORECAST

Today: Partly to mostly sunny. 83-87. Tonight: Partly cloudy. 63-67. | Tomorrow: Partly sunny. Isolated shower? 83-87 | A Look Ahead

FORECAST IN DETAIL

Once we reach late June in Washington, we should count our blessings for every day that the temperature does not exceed the mid-80s and humidity stays in the tolerable range. After two straight days of such conditions, wet get to look forward to two more. But Thursday, we climb back up towards 90 with increasing humidity and late-day thunderstorm chances. Unfortunately, this sort of sticky and sometimes stormy weather may last through the weekend.

Today (Tuesday): Just like yesterday, we'll have a mix of clouds and sun with temperatures warming into the low-to-mid 80s. Cloud cover may be a little less than yesterday, so be extra sure to wear sunscreen if spending more than a few minutes outside. A light breeze from the north at around 10 mph will feel refreshing in the warm sun. Confidence: Medium-High

Tonight: Just a few clouds will dot a mostly clear sky. Lows should range from the low 60s in the coolest suburbs to the mid-to-upper 60s downtown. Confidence: Medium-High

Keep reading for the forecast through the weekend...

Tomorrow (Wednesday): Unfortunately, this may be the last day in the stretch of temperatures at or below average along with bearable humidity levels. Highs aim for the mid-80s under partly sunny skies. We run a slight risk (20% chance) of a shower or thunderstorm, especially late in the day. Confidence: Medium-High

Tomorrow Night: Outside a 20% chance of an evening shower, skies will be partly cloudy. Lows will reach the mid-60s in the cooler suburbs to near 70 downtown. Confidence: Medium-High

A LOOK AHEAD

We won't have the benefit of a cool north breeze Thursday or much in the way of cloud cover. So it will turn hot. Highs will likely reach the low 90s. Humidity levels won't yet be brutal (dewpoints in the mid-60s), but slightly more noticeable than in preceding days. At night, it will be muggy, with a 1-in-3 chance of thunderstorms as a front approaches. Lows will only be in the upper 60s to low 70s. Confidence: Medium

Though a front will pass through the region Thursday night, it won't push far enough away to displace to warm, humid airmass for Friday through the weekend. Throughout the period, it will be partly sunny, very warm, and sticky (dewpoints near 70), with highs in the upper 80s to near 90. Night times won't offer much relief, with lows 70-75 (suburbs-city). Each day will carry a 30% or so chance of showers and thunderstorms, especially in the late afternoon and early evening. Confidence: Medium

Comments

Local weather coverage, aside from the Weather Channel, and supplemental digital channels, was virtually nonexistent due to the Metro accident coverage yesterday evening. Channel 9 blocked even the national 6:30 PM national news. Much of the special "breaking news" coverage was repetitive with few new developments occurring, and there should have been pauses in the accident coverage to cover other news [Iran, etc.] as well as local weather & sports. IMO I think that blocking the half-hour of national network news was not warranted by the situation. There should also have been a better screen display of the emergency phone number available for friends and relatives of people on the two affected trains.

BTW the news last night about delays, closure etc. on the unaffected portion of the Red Line was inaccurate. By 9 PM I was able to get to the Chevy Chase Ballroom [Friendship Heights] and back with minimal delay. The service was actually better than Red Line service on some "normal" Monday and Friday nights.

Weather thus far this week is drier than that of recent weeks.
