Wow, what is going on? The last two days have come in slightly cooler than normal, three of the last four days have been only in the 80s. Also, rainfall at Reagan National is running about twice normal for the month of August.
We have seemingly flipped into a new summer paradigm, and I’m certainly not opposed to it. In fact, the coming forecast period should stick to the 80s for highs and we see more rain opportunties today and then Thursday into the weekend. The big bothersome hot dry ridge pattern from June and July is too busy out in the Plains, Texas, and Western states to bother us for now.
Today (Tuesday): A sluggish low pressure area is ambling out of the Northeast today. Its debris around the Mid-Atlantic triggers more showers and storms this afternoon. Coverage and intensities should be less than yesterday with just a 20-30% chance of afternoon/evening thundershowers mainly to our north and east. Partly sunny skies, coolish breezes from the north at 10-15 mph, and highs in the mid-to-upper 80s offer up a decent day. Confidence: Medium-High
Tonight: Partly cloudy, lingering evening showers/storms possible, and comfortable with lows from the low to upper 60s. Confidence: Medium-High

Tomorrow (Wednesday): High pressure visits for a short while to offer us the best day of the workweek. Prepare for mostly sunny skies, temperatures in the mid-to-upper 80s again with light winds and relatively low humidity levels. The afternoon sun may feel a bit hot (it is still August after all), but think back to the big 90s and 100s of the past two months for consolation. Confidence: High
Tomorrow night: Increasing clouds with lows from the middle to the upper 60s (probably holding close to 70 right in the city). Confidence: Medium-High
Thursday through Saturday brings in another weather disturbance that will offer us more mainly p.m. storm chances, variably cloudy days, slightly more humidity, and temperatures mainly in the mid-to-upper 80s. Thursday could be the warmest day with more upper 80s, and Friday aims to be the wettest day potentially. Probability of precipitation is 40% Thursday, 60% Friday, and 30% Saturday. Lows should range from the middle 60s to the low 70s. Confidence: Medium
Sunday is a trickier forecast right now as some guidance suggests we linger with the unsettled weather (partly cloudy skies, 30% chance of rain) and other guidance suggests we get a sunny/dry day (mostly sunny and warm). I’m favoring the better weather break for right now as more unsetted weather comes in early next week. Highs in the mid-to-upper 80s, lows in the 60s with partly to mostly sunny skies. Confidence: Low-Medium
