FORECAST IN DETAIL


Yesterday’s high temperature at National Airport of 87 degrees was the “coolest” maximum reading since we felt a pleasant 82F way back on June 26th. It was also two degrees below normal for the date. This new cooler pattern continues through this week with occasional bouts of cloudiness and shower/storm chances.

For the most part, our high temperatures run near to below normal, while low temperatures hold near normal or are sometimes slightly higher. The weekend starts to get a bit hotter and a little more humid, but nothing like our recent blowtorch.

Today (Tuesday): With a pesky stalled front to our south, we contend with more cloud cover today and the risk of showers or storms (30% chance) - most likely in the afternoon (but a few light showers can’t be ruled out in the morning). Any storms could be slow-moving, so if you get one, you could get a drenching. Partly to mostly cloudy skies prevail with high temperatures ranging through the 80s. Light winds flow in mainly from the east. Confidence: Medium-High

Tonight: Partly cloudy with a 30% chance of evening storms. Lows from the middle 60s in the outer suburbs to near 70 in the city with light east winds. Confidence: Medium-High

Tomorrow (Wednesday): A better chance for prevailing sunshine with still a lingering 20% risk of a thundershower. Highs mainly in the mid-to-upper 80s, but our humidity may come down a slight bit for improved comfort. Confidence: Medium-High

Tomorrow night: A few clouds with lows again in the middle 60s in the suburbs to around 70 in the city. Confidence: Medium-High

A LOOK AHEAD

Thursday might be the best day of the week in terms of temperatures and general weather. Look for partly to maybe mostly sunny skies with highs in the low-to-mid 80s. Thursday night should see a few clouds again with lows dipping from the low 60s to near 70. Confidence: Medium-High

Friday and the weekend are still rather tricky as we expect the stalled front to our south bounces back north as a warm front. Depending on the details, it could delivery significant precipitation to our area. Unfortunately the guidance varies on timing. For now, the safest thing to say is a 40% chance of showers/storms each day (especially afternoon into evening). Partly to mostly cloudy skies dominate and temperatures slowly increase. Highs on Friday should be in the low-to-mid 80s. Mid-to-upper 80s are favored for Saturday with possible upper 80s to low 90s (gulp) on Sunday. And humidity increases during this period. Lows range from the upper 60s up into the low-to-mid 70s. Confidence: Low-Medium
