Today's Daily Digit
A somewhat subjective rating of the
day's weather, on a scale of 0 to 10.


A warming trend begins & humidity grows. Not sure I'm liking this.

Today:Mostly cloudy with 30% chance of showers. 80-85. | Tonight: Chance of storms early. Muggy. 67-73. | Tomorrow: Partly sunny, very warm, humid, slight chance of storms. 89-93. | A Look Ahead | Get Express Forecast by E-mail


Yesterday's overcast afternoon capped temperatures in the low 80s, the coolest conditions in a month. If only the first day of August was a harbinger of the weather to come. But no, a warming trend begins tomorrow and another serving of sultry air grips the area through Thursday. As the mercury climbs, we'll have to keep an eye to the sky for the next several afternoons and evenings as the steamy air may support development of thunderstorms.

Today (Monday): Although it appeared like may see more sunshine compared to yesterday, moist flow from east and south (at around 10 mph) has held considerable cloud cover over the region. The end result is day a much like yesterday with the occasional interval of sunshine, a few scattered showers and highs in the low 80s. Confidence: Medium-High

Tonight: Any scattered showers probably move off and/or dissipate by mid-evening (8-10 p.m.) so Screen on the Green-goers probably (80% chance) stay dry. Later at night, as the flow from the south becomes more entrenched, the humidity builds with lows in the upper 60s to low 70s (downtown). Confidence: High

Tomorrow (Tuesday): The kind of heat and humidity we've become accustomed to this summer returns. Under partly sunny skies, highs head back towards the low 90s and it's humid - with dew point in the high 60s. A couple thunderstorms could pop up, but odds you get hit are just about 20%. Tropical breezes from the south blow at 10-15 mph. Confidence: Medium-High

Tomorrow Night: It's another one of those muggy, summer evenings. Outside some isolated evening storms, skies are partly cloudy, with lows 70-76 (suburbs-city). Confidence: Medium-High


Both Wednesday and Thursday are hot and oppressively humid as moist tropical air continuously funnels into the region. Highs each day reach the mid-90s with upper 90s possible with enough sunshine. The afternoon clouds that potentially put a lid on temperatures could grow into thunderstorms -- especially late Wednesday into Thursday as a front comes through. The odds of storms are around 30% on Wednesday, 50% Wednesday night and 40% on Thursday. Overnight lows Wednesday and Thursday night are in the 70s. Confidence: Medium

On Friday, high pressure starts building back into the region behind Thursday's cold front. The front, however, hangs up just to our south which means the cooler, drier air won't replace the hot, moist air immediately and we'll keep a 20% chance of storms in the forecast (higher odds south and southeast). Highs will be near 90. Clearing Friday night, with lows from the 60s in the suburbs to near 70 downtown. Confidence: Medium

The weekend looks quite good for the moment. The humidity will drop as high pressure to the north establishes itself. High both days should be in the 85-90 range with overnight lows in the 60s to near 70. Confidence: Medium

I don't know about anyone else, but my personal daily digit for yesterday was a 9. It only missed being a 10 by virtue of not enough rain falling in my neighborhood! If we have to have the heat back, at least give us a steady light rain every afternoon from 2-3 for a week. That way it shouldn't ruin the day of the lunch crowd, the commuter crowd, and even the "much needed dance" crowd should be able to avoid soiling their dancing shoes.....

ftwash - I thought yesterday was pretty swell, too. You are good-willed to figure out that good window for rain ;)

As long as the rain ends by 2:45 pm or so--I generally go to Ballston several afternoons per week.

Today is more rainy than the TV mets were saying last night--they seem to have thought this Atlantic rain would be out of here by daybreak.

At what point do you think we can begin idle speculation about TD 4 impacting our region?
