Seasonable temperatures and dry weather will be a nice break from the recent humidity. Finally there won't be any of those pop up thundershowers to least not until Sunday and Monday. Even then this will be a generally dry period as we watch our rainfall deficits continue to grow and our garden's growth curtailed. The longest day of the year arrives on Monday with plenty of heat and humidity to mark the occasion.

Today (Thursday): A noticeably drier feel will be in the air this morning. Mostly sunny skies accompany brisk breezes from the northwest that push the humidity out to sea. Morning 70s give way to afternoon 80s. Confidence: High

Tonight: Winds lighten up and temperatures drop off quickly to the upper 70s, making the evening quite enjoyable with no worries about rain. Lows will range from upper 50s in the suburbs to mid-60s downtown. Confidence: High

Keep reading for the forecast through Monday...

Tomorrow (Friday): Sunny skies rule this day and humidity levels remain quite comfortable. Light winds from the north should be enough to keep outdoor goers from overheating even with highs in the mid-to-upper 80s. Confidence: High

Tomorrow Night: This is a wonderful way to kick off the weekend. Evening readings will be in the upper 70s to lower 80s and winds will be calm. Humidity will not make its return until tomorrow. Confidence: High


Saturday dawns with a little more humidity and ends with a little more heat. Skies remain sunny and winds stay light from the south at 5 to 10 mph. Most of the area should reach 90 for a high and air conditioners ramp up. The plus for this day is still no threat of any pesky showers. Confidence: High

Sunday starts out near 70 but hits 80 by mid-morning and should be pushing 90 by midday. Highs should stall out in the mid-90s as long as clouds start popping up early enough in the afternoon. That will mark the return of the afternoon and evening isolated thundershowers to the forecast. However, only about 20% of the area is likely to see enough to measure. Confidence: Medium-High

Monday marks the summer solstice at 7:28 a.m., with the sun hitting its highest angle of the year! Heat and humidity are likely to remain firmly in place as a very weak cool front should remain just north of the region. Highs again rise rapidly but should be a few degrees short of the previous day -- in the low-to-mid 90s -- as pop up clouds arrive a little earlier. Those pesky late afternoon and early evening thundershowers should hit about 20% of the area. Confidence: Medium-High

Are you guys going to continue with your "Strascast?"

Looks like he and the fans will have a decent night tomorrow.

We just did StrasCast for his first start. StrasCast is a little duplicative with NatCast so don't see much value added doing both the whole season. While we did StrasCast in the days leading up to the first game and NatCast is only available the day of the game, StrasCast was then a little duplicative with our regular forecasts. It just gets to be a little bit much with all of the extra 'casts' on the blog.

In any event, as our forecast makes clear, tomorrow night looks great.

Dew point at 58, trees showing a breeze, blue sky, and wispy clouds from my window...its a 10 in my book.

AC off, windows open. Had a very comfortable run on the Georgetown trails this morning. Agree it feels like a 10.

I deducted a point for too windy and a point for high in mid 80s. But have to admit is sure does feel splendid compared to recent days!

agree with downgrade ;) just a bit below 10.. nicer than recent! so, an 8 on our relative summertime scale is pretty good!!
