Forecast: Unsettled Sunday Afternoon

By Brian Jackson

It will feel almost spring-like today and tomorrow across our area. Temperatures barely above 80 with low humidity? Not really what one would expect during early August in the mid-Atlantic. Still we'll have a chance for storms today, despite the lack of high humidity, along and ahead of a strong cold front. Behind the front and into mid-week we'll continue with the pleasant conditions before our next chance for rain on Wednesday.

Mostly cloudy. Chance of thundershowers. 80-85. Cloud cover will be moving in today ahead of a cold front along with some afternoon showers and possibly a few rumbles of thunder (50% chance). A few storms may contain gusty winds and hail due to cold air aloft. Temperatures will top out in the low 80s but may creep a bit higher depending on the amount of sunshine. Winds from the southwest will blow at 5-10 mph.

Showers will be on the decrease during the evening and the front should be out of our area by midnight or so. After the passage, skies will begin to clear and temperatures will be pleasant for sleeping, dropping to the mid 60s downtown to near 60 in the suburbs.

Confidence: Medium-High

Keep reading for the forecast into early next week.


Becoming mostly sunny. 78-83. Skies will continue to clear during the morning hours on Monday. Afternoon highs around 80 degrees will combine with low humidity to bring us excellent outdoor weather. We may see some afternoon cumulus develop with the cold air aloft, a stray drop or two may even be squeezed out to the north. However, rain drops will be the exception and most everyone will have pleasant summer skies. Winds will be from the west at 10-15 mph.

Monday night will be another crisp one for this time of year. Clear skies and light winds will allow temperatures to fall to 60 in the city and even some 50s in the cooler suburbs. So give the A/C a break and sleep with the windows open, if you can stand the crickets.


For Tuesday, temperatures begin to climb back up to normal. Skies will be mostly sunny with an afternoon high in the mid 80s. Confidence: Medium-High

Wednesday holds another chance for rain late in the day. It will start out nice though with partly sunny skies. Afternoon highs will reach the mid 80s before clouds begin to increase. We'll have a 30% chance for an afternoon shower or thunderstorm. Confidence: Medium-High

Check out the extended 06 GFS - 300 hours out. Recognizing that this is way too far out to be a reliable indication of what's going to happen, having a large tropical system right over DC is still an interesting scenario. Plus the experimental cyclogenesis graphics depict two systems, one following the other through the Windwards. Will be an interesting time, not only today, but perhaps week after next.

300 hours is what ... 13 days? That's way to far in the future for me to be worried about what a computer model is saying. What I have my eye on is the occurrence of thunderstorms this afternoon.

Looking forward to seeing that Nice Day Stamp tomorrow!

Well, it's all breaking up. I don't care what the numbers say, we are once again seeing summer drought. I hope we get a tropical system, once that lasts for two or three days with steady, but not severe, rain. Soils very dry and compacted.
