* NatCast | Current Temps and More: Weather Wall *

EXPRESS FORECAST

Today: Cool & cloudy. Some showers, mostly south of D.C. 73-76. | Tonight: Isolated shower early? 62-65. | Tomorrow: Becoming partly sunny. 81-84. | A Look Ahead

FORECAST IN DETAIL

An area of low pressure arriving from the Great Plains brings clouds, cool temperatures and, for some, the chance of showers today. Areas to the south will see the best chance of occasional rain, while for D.C. and areas to the north there's the chance for nothing but clouds and a passing shower or two. I guess we'll call this paying our dues for this week as sun, low humidity, and warmer temperatures (just slightly below normal) return for the extended period.

Today (Sunday): Lucky for us, we avoided any atmospheric "fireworks" during last night's patriotic celebrations. Don't expect any big boomers today but areas south of the city may get some periods of steady rain (60% chance), up to a quarter inch or so well south of town. There is a good chance those of us from D.C. northward stay pretty dry save for a couple passing showers. For everyone, skies will be mainly overcast for the better part of the day, holding afternoon highs to the low-to-mid 70s. Winds will be out of the south and light. Confidence: Medium

Tonight: An isolated shower may linger into the evening/overnight. Skies will continue to be overcast but should slowly clear. Clouds will keep our temperatures fairly steady with overnight lows in the low-to-mid 60s. Winds will be out of the north at < 5 mph. Confidence: Medium-High

Tomorrow (Monday): We'll begin the week the right way as the warm temperatures and low humidity make a return, much to the delight of those of you that work outside. Lingering chances for showers remain (20%), especially for anyone who'll be up super-early. Skies will continue to clear in the wake of this system, and we'll see a fair mix of sun throughout the day. Afternoon highs will climb into the low-to-mid 80s but dew points in the mid-to-upper 50s will make it feel quite dry and comfortable. Winds will help as well, blowing from the north at 5-10 mph. Confidence: Medium-High

Tomorrow Night: Another pleasant night is in store for the region tomorrow night. Partly cloudy skies will allow temperatures to fall to the low 60s (mid-60s in the city) overnight. Confidence: High

A LOOK AHEAD

Tuesday will again be a great day across the region. Partly to mostly sunny conditions will be widespread and low dew points will be sticking around to keep us dry. Afternoon temperatures will again climb into the mid-80s. Another disturbance overnight keeps a minor chance for a shower or two in the forecast for northern areas, but again should be few and far between. Overnight lows will be in the mid-60s Confidence: High

Not much will be changing on Wednesday except that winds may begin a southerly turn and could start to slowly bring up our humidity. Still, we won't be reaching any oppressive levels and it will continue to feel quite comfortable. Mostly sunny skies will prevail and afternoon highs will again top out in the mid-80s. Overnight lows again will reach the mid-60s (upper 60s downtown). Confidence: Medium-High

After a very pleasant Independence Day, much needed rain is falling this morning,
.35" at 10:30.

A very cool 60 degrees at 10:30 feels more like late September than early July.

Surely this must somehow be related to "Global Cooling"!!

Have a great Sunday everyone!!!!!!!!

June of 2009 was the coolest since 1958 at Central Park and the second wettest on record.
