Will this pattern of humid days with their heavy downpours clear out in time for the 4th of July? And how does this very wet month rank among history's wettest?
After a beautifully sunny and comfortably dry Saturday, our fortunes have reversed today. Very high humidity levels are back as is the threat of thunderstorms and heavy rain. In fact, the same tropical pattern of the past week will dominate our weather for most of the coming week. A Flash Flood Watch will go into effect this evening and extend through Monday in anticipation of heavy downpours falling onto already soaked soil. With almost 10 inches of rain at Reagan National this month, this June is the 4th wettest on record dating back 142 years.
Today will feature mostly cloudy skies with highs in the mid 80s. There is 60% chance of showers and thunderstorms throughout the afternoon and on into the evening hours. Some of the heaviest rain could fall overnight. With the same humid air mass in place into the coming week, each day carries with it the possibility of showers and storms. Daytime highs through the period should average in the mid 80s.
As our two big weather influences - the upper level low and the Bermuda High off the Atlantic coast - begin to breakdown and move later this week, we can look forward to warm, but somewhat less humid and more stable air by week's end. That, and the 4th of July, are events worth celebrating! Enjoy your Sunday.
