Forecast: Overcast, Showery End to the Week

By Josh Larson

More sun, warmer weather expected this weekend

With the area of low pressure related to the remnants of Fay spinning to our south and west, we can expect plenty of clouds over the next 36 hours along with periodic showers -- especially to the west of DC. However, this precipitation won't put too much of a dent in the recent rainfall deficit. And odds are that, going into the weekend, we'll see warming temperatures and, save a shower on Saturday, mainly dry weather.

TODAY (THURSDAY)

Overcast with showers. Mid 70s. You'll wake up to thick overcast skies today with temperatures in the mid 60s in the morning. Most of the day will feature periodic showers, mostly of the light to moderate variety; heavier rain will remain well west of DC. Winds from the east around 10 mph will hold highs in the mid 70s.

Overcast skies will linger this evening with occasional showers through the course of the night. Lows will drop to the mid 60s in most locations.

Confidence: Medium-High

Keep reading for the forecast through the beginning of next week. Also, see SkinsCast for tonight's preseason game at FedEx, and Natcast for this evening's game against the Dodgers.

TOMORROW (FRIDAY)

Mostly cloudy; showers. Near 80. Friday morning will feature overcast skies and occasional showers or drizzle. Some brightening of the sky may occur during the middle of the day when precipitation should become spotty. By late afternoon you may even see some patches of blue sky, boosting afternoon highs to near 80.

Evening plans Friday night? Plan on partly cloudy skies with a rogue shower unlikely though not totally out of the question. Overnight lows will be in the upper 60s.

A LOOK AHEAD

Despite the fact that a weak cold front will approach the area on Saturday, we can still expect a fair amount of sunshine, especially during the second half of the day. That being said, a shower is possible. It will be warmer, too, with highs rising to the mid- to-upper 80s depending on how much sunshine we see. Saturday night will be mostly clear and dry with lows near 70. Confidence: Medium

It's not too surprising that the sunniest day over the next few days -- Sunday -- will also be the warmest. Expect mostly sunny skies and comfortable humidity levels, with highs near 90 and overnight lows in the upper 60s. Confidence: Medium-High

The outlook for Monday -- Labor Day -- calls for partly to mostly sunny skies and a low chance of precipitation and warm afternoon highs in the upper 80s and overnight lows in the mid to upper 60s. Confidence: Medium

There must be a dance on tonight.

TD8 will become Hannah at 11am.

Plenty of rain here in McLean since I woke up an hour ago. I don't have a working rain gauge nearby, but I wouldn't be surprised if we've received a half inch since all this began.

What can we expect for cloud height late tomorrow morning in the Baltimore area? How quickly is this thing going to clear out?

How can storm have a pressure of 983mb and still be a tropical storm? Are the surrounding pressures that low? What is the team's thought on wind being an accurate measurement of storm strength versus pressure?

@ Mike, pressure drops can precede an increase in wind velocity.

DCPilot: This system may be slow to move out, so cloud heights may remain on the low side tomorrow morning.

Murre, that is a fair point. However, implicit is the assumption that a aircraft can accurately measure wind speed. Storms are not symmetric and you will have differences in wind speed around the eye wall.

Current: 71F, 30.04, falling, As, Ns, light rain with "intervals" [a British twist] of heavier precipitation. Rain field movement S to N rather than the usual W-E.

Gustav and Hanna [NHC's spelling!] figure to make this a busy weather weekend. NHC is still progging Gustav towards the Big Easy, w. Category 3 [or higher]. Both storms/remnants thereof could affect us in next two weeks, ending our spell of nice weather.

@ El Bombo, similar weather in eastern Loudoun. Breezy at times as well.

Any updated guesses as to when the rain will move out of the area?

Posted by: Greenbelter | August 28, 2008 1:02 PM | Report abuse

Steady area of rain has mostly moved to the north. Showers are still possible through the afternoon and tonight, but likely to be scattered in nature and fairly light. Stay tuned for PM Update between 3 and 3:30 p.m.

Wind is a better measure of storm strength than minimum pressure. As mentioned above, wind is very closely tied to the pressure gradient, not the lowest pressure alone.

Keep in mind that officially intensity is the maximum near surface wind - any where within the storm domain. Intensity alone tells you nothing about the distribution of winds about the storm center, e.g., in which quadrant and at what distance from the storm center the maximum winds are located - nor the radial extent of hurricane force winds. Invoking "rules of thumb" alone, e.g., max winds occur on the on the forward right quadrant, can most assuredly result in a broken thumb. Hurricane force winds can extend outward anywhere between just 10-20 to perhaps 300-400 miles.
