With temperatures expected to reach the 90s starting tomorrow, the D.C. region is bracing for a prolonged heat wave accompanied by limited chances of rain this week. The hot and dry conditions have raised concerns of a possible flash drought, highlighting the need for precautions and water conservation.

According to forecasts, temperatures may soar to 90 degrees or higher each day for the foreseeable future. While there is a slight chance of scattered showers or storms, the overall weather pattern leans towards dry conditions throughout the workweek.

Tonight, high clouds are expected to clear out, providing mostly clear conditions. Although breezes from the south may gust up to 15 mph initially, they are likely to settle down by sunrise. These breezes are gradually increasing atmospheric moisture, slightly raising the humidity levels. Overnight temperatures are anticipated to range from the mid-60s to around 70 degrees.

Tomorrow, the mercury will climb into hot territory, reaching around 90 degrees to the low 90s. The higher humidity levels will contribute to a heat index that makes it feel like the mid-90s. It is advised to stay hydrated and take necessary precautions to beat the heat. Breezes from the south, while responsible for the increased heat and humidity, may occasionally gust up to 20 mph, providing some momentary relief.

In the afternoon, a small spike in cloud cover may bring a 10 percent chance of a quick shower or thunderstorm. Any clouds would be welcome, as they would shield the region from the strongest sun of the year. Overnight, skies are expected to be mostly clear, with lighter breezes and temperatures in the upper 60s to low 70s, making it feel even more humid and stuffy.

High pressure will dominate the region throughout the week, resulting in mostly dry conditions. The next opportunity for rain may not come until the weekend, which will put additional strain on gardeners and farmers who will need to increase watering demands. The combination of high heat and intense sunlight will accelerate evapotranspiration, adding to the water needs.

The Climate Prediction Center has issued a warning about the twin threats of excessive heat and flash drought. While the region is not currently facing an official drought, many areas are considered abnormally dry, with recent rain chances being more miss than hit. Over the past 30 days, the D.C. region has experienced below-average rainfall, leaving a deficit that makes it susceptible to a quick-onset "flash drought" within such a short period.

As the region prepares for the prolonged heat wave and potential flash drought, experts recommend staying informed about the latest weather updates and taking steps to conserve water. It is crucial to stay hydrated, limit outdoor activities during the hottest parts of the day, and check on vulnerable individuals, such as the elderly and children, who may be more susceptible to heat-related illnesses.
