A big surge of tropical moisture coming up from the south and an approaching Midwest storm from the west will give us humidity and the likelihood of thundershowers in the next two days. Yes, this is one slow moving storm! A few severe storms are possible as well, so don’t lose track of what is going on. The payoff is a well-timed, dry weekend with seasonable temps. Looks like another return of thundershowers for back-to-work Monday, gardeners rejoice.

Today (Thursday): This forecast could quickly get off to a rocky start if I miss the mark on thundershower timing! I am betting a line rolls through here this morning. Hopefully that will limit its severe potential. Enough midday clearing should allow for temperatures to zip back the upper 80s and lower 90s depending on how much sun time we get. Late afternoon thunderstorms are also possible with emphasis on late. Those have a better chance of being severe (high winds/small hail). Rain chances are 60% for the day as a whole. Winds blow from the southwest at 5-10 mph, except in the storms. Confidence: Medium

Probability: 60%
Coverage: Scattered
Most Likely Timing: 5 to 9 a.m. and 5 to 9 p.m.

Tonight: The bulk of the thundershowers (still that 60% chance) should taper off fairly quickly after darkness settles in. Breezes from the west are only 5-10 mph and except for rain cooled areas readings will be in the 80s with plenty of humidity to keep muggy on our minds. Lows range from the mid 60s outlying areas to lower 70s downtown. Confidence: Medium

Tomorrow (Friday): Look for a good deal of sun in the morning. However, that big Midwest storm gets close enough to cloud things up by midday. That could help to cut down on the heat a little with most highs in the mid-to-upper 80s. There is still likely to be afternoon thundershowers pin wheeling around that big system with best chances for storms north and west of D.C. but nobody gets a free pass. Look for at least half of the area to get a shower or two. The atmosphere is unstable enough that the risk of severe weather remains. The humidity is still high and breeezes blow from the southwest at 5-15 mph. Confidence: Medium

Tomorrow night: Thundershower chances of 30% carry over into the evening with placement to favor south and east of the city. Evening readings are upper 70s to lower 80s. Breezes continue to come from the west at 5 to 15 mph. Overnight lows slip to the lower 60s suburbs to upper 60s downtown. Confidence: Medium


Saturday is a great day for hiking, swimming, biking, beaching...whatever your outdoor activity of choice! Skies will be clearing and even the humidity is just a smidgen lower. With our summer sun as high in the sky as it is going to get, temperatures still move up at a good pace. Most areas can count on mid-to-upper 80s for highs. Breezes from the northwest are quite light. There is only the smallest chance of a late day thundershower (less than 20%). The evening is great for getting out too. Lows should hold in the mid-to-upper 60s. Confidence: Medium

Sunday is another lovely summer day with highs rising to the mid-to-upper 80s. Humidity is manageable and skies are mostly sunny from start to end. Evening readings hold in the upper 70s and lower 80s. Lows should reach the upper 60s to lower 70s. Confidence: Medium

Monday looks like a good day to go back to that air-conditioned office as temperatures and humidity are on the way up. This is courtesy of a warm front which is likely to focus thundershowers over the area by afternoon (40% chance). Highs reach the upper 80s to lower 90s. Confidence: Medium
