PM Update: Showers threaten tonight and tomorrow

By Ian Livingston

Beautiful "fall preview" mid-to-late week

* Greenland's ice island drifts from land | Danielle unlikely to threaten *
* Outside now? Radar, lightning, temps & more: Weather Wall *

Moderated humidity levels and temperatures in the low-to-mid 80s feel mighty fine today, and cool weather fans have a fair amount to cheer about over the coming few days. Clouds now on the increase foretell a chance of showers late today through at least late tomorrow, but after that we break out into some gorgeous weather for a few days. Even with no 90s on the immediate horizon, don't put away the shorts just yet.


Radar & lightning: Latest regional radar shows movement of precipitation and lightning strikes over past two hours. Refresh page to update. Click here or on image to enlarge. Or see radar bigger on our Weather Wall.

Through Tonight: Skies continue to cloud up and showers become more likely heading through the rest of the afternoon and into this evening. Showers then remain possible throughout the night, but it should be hit-or-miss with no one really getting a bunch of rain. Temperatures fall to minimums in the low-and-mid 60s.

Tomorrow (Tuesday): Clouds, showers and a wind from the north and northeast will combine to make for one of the cooler days we have seen all summer. As with tonight, it does not look like we can expect high rainfall amounts, but showers will be possible throughout the day. With all the clouds and such, highs probably only rise into the low-and-mid 70s. If/when National Airport misses 80 tomorrow, it will be the first time since June 9.

Riding into gray skies west of the Blue Ridge. In winter this would be a 2-3 foot upslope snow event in WV but the predicted snow for the city would be a bust.

Let's break this 80's streak.
Very brief, light showers for the past couple hours in Centreville.
Now that I've given up hope for something measurable and hauled the watering cans around we'll probably get a nice drenching overnight.

OMG, the NWS is saying we may have TWO straight days (Tues, Wed) when temps fail to hit 80. Wonder when the last time that happened was.

June 8-9? Or earlier??

I would feel so good about this cool down but I keep looking at the Acuweather forecast for the first week from 8/31-9/6 and cringing. Seven straight days of mid-90s we don't need, even though it would make me eligible for the Best Buy lottery.

This is quite early for fall-type weather.

Generally weather of this type waits until after Labor Day. Labor Day is still a couple of weeks away.

It's also likely that this extended cool spell busts our chance of setting a new record for most 90-degree days in a summer. We still need 12 or 13 such days to break the record of 67. On the plus side, we've probably seen our last triple-digit heat for the year.

I was just awakened by thunder, lightning, and extremely heavy rains. It was not visible on radar, but then I looked closer, and this cell is very isolated over north central Stafford County. The rainfall rates are tremendous and certainly flash flood level. I couldn't believe how this cell just formed out of nowhere and did not move. I will have to check the rainfall totals later today, but it should be tremendous based on the rates I am seeing outside.
