EXPRESS FORECAST

Today: Sunny. 82-86. Tonight: Partly cloudy. 57-61. | Tomorrow: Mostly sunny. 84-88. | A Look Ahead

FORECAST IN DETAIL

Fantastic July weather continues to be the headline for our local weather. We are still rarely breaking above 90 degrees. Cool winds from the north will assist a slightly less warm today and a cool night tonight. A warm push is expected Wednesday into Thursday, and there is a chance to see a break above 90 on Thursday. However, showers/thunderstorms that afternoon could thwart the attempt. July has not offered much precipitation yet, so some showers might be welcome.

Today (Tuesday): More sunshine today with warm temperatures and low (especially for July!) humidity levels. Look for low-to-mid 80s for highs and light breezes from the north as pleasant Canadian high pressure approaches.

Tonight: Mostly clear skies with light breezes can be expected. Temperatures should drop very low for this time of year with comfortable low-to-mid 60s in the city to potentially mid-to-upper 50s in the suburbs. That cool high pressure should be right overhead. Confidence: High

Tomorrow (Wednesday): High pressure moves into the Atlantic tomorrow and allows for a warming trend to return as winds shift and come from the west and southwest again. Look for both temperatures and humidity to creep higher again. Highs should be in the mid-to-upper 80s with still mostly sunny skies. Confidence: Medium-High

Tomorrow Night: Some additional clouds will arrive over the area and we'll see more effects of that humidity as temperatures stall in the upper 60s to low 70s around the area (warmest in the city). Confidence: Medium

A LOOK AHEAD

Thursday is supposed to be our warmest day of the week and higher humidity will certainly help it feel that way, but frequent cloud cover and scattered showers and thunderstorms (40% chance) will likely only allow temperatures to reach into the upper 80s (could be a spotty 90 around the area). Winds should be from the southwest. Confidence: Medium

Friday should see an early day cold front lead the way back toward cooler conditions with highs in the low-to-mid 80s once more via drying winds from the northwest. Partly sunny skies are anticipated. Confidence: Medium

The easy part about the weekend outlook is that temperatures should be nothing to complain about with mostly nice-for-July middle 80s. The tricky part is what to do with a stalled front to the south and whether a ripple along that front brings showers or thunderstorms to the area on both days. Right now, we'll stick with a 30% chance of precipitation under partly sunny skies. Lows should mainly be in the comfortable 60s once again. Confidence: Low

Beautiful morning, but bordering on cold in a couple spots. Martinsburg, WV was 51 and Petersburg, WV was 48 degrees at 7 a.m. Hard to believe it's mid-July!

I would have to agree. I actually had to close my bedroom window early this am. Though that may have been due to an annoying songbird rather than the chill...

Gorgeous morning... dewpoints down into the mid 40s most of the area. Feels like the end of summer/beginning of fall with the breeze.

This is truly a Los Angeles kind of weather no clouds low humidity and warm afternoons.

The dew point is down to 38 at Dulles! Amazing for July...

Right, Ian. Usually a midday temperature around 75 at this time of year is accompanied by a dewpoint aoa 72 and damp, mold-promoting cloudy to wet weather.

We are actually beginning to see a few lawn sprinklers and dry patches around here...but we're still in no drought and don't need any "much-needed-rain" requests.
