PM Update: A Few Showers, Storms Here & There

By Ian Livingston

Warm and muggy Wednesday. Any showers?

* NatCast | Record Low Dew Point? | Washington's Lightning Rod *

Some isolated showers and maybe a thunderstorm will be around late afternoon and into evening and maybe again overnight. On the temperature front, we're right about in the middle of our typically hottest 10-day stretch of the year, and yet it's not too toasty as highs today top out in the low-to-mid 80s. We should feel a bit more July-like tonight and tomorrow as winds come more from the south than off the ocean.

Through Tonight: Evening brings partly to mostly cloudy skies and the risk of a shower or storm while temperatures fall into and through the 70s. We'll stay partly cloudy overnight with perhaps another passing shower late as a warm front lifts north through the area. Lows should fall to the mid-and-upper 60s.

Tomorrow (Wednesday): Mild and muggy weather is on tap for Wednesday. It's another day with a fair amount of clouds, but probably enough sun to get highs to at least the mid-80s as humidity climbs a notch higher. A couple afternoon/evening showers or storms are possible, but coverage should be limited once again.

Precipitation Swings: If we go back about a month, we were seeing rain on almost a continual basis along with rainfall totals that were well above normal for the month of June. Now, we are begging for a drop. Last night, NBC4's Bob Ryan mentioned this is the driest July on record so far, and right now by a decent margin. Through publish time, DCA has recorded only .26" of rain in July. Other dry Julys and benchmarks to watch during the final days of the month: 0.82" in 1871, 0.93" in 1966, 1.01" in 1999 and 1.05" in 1957. See a full list of July's with less than 1.50".

Luckily the rain chances appear much slimmer tonight, than this time last night. Get out and enjoy - ignore the clouds! haha

Some stuff popping up near Bowie, looks like a little boundary near DC area drifting north.

We're getting a shower on the Blue Ridge east of Front Royal. We need the rain... I watered our dogwood trees on Sunday as they're not looking so great. We got some rain yesterday, but it didn't amount to much.

Low this morning: 58.8F
Hi today: 81.7F
Currently: 66.9F

In other news, we went to Glen Manor vineyard in Browntown last Friday. We really liked their wines and found the free tastings refreshing.

On a weather note, I think the winegrower/winemaker said that the cool nights we've been having are desirable. So depending on the next couple of months, this year could be a good vintage.

It may be a dry month, but we were very wet the past three months.
