      The possibility of showers and heavy downpours this weekend, while a complication for outdoor plans, will help to reverse this season's{}very hot and very dry pattern.{} As measured at Reagan National, the rainfall deficit for the year is now over 5 inches with these past three summer months all being disappointments in reducing that number.{} And while the number of 90 degree plus days continues to climb - the 46th such day was recorded yesterday - a different, but equally revealing statistic on the summer's heat is the fact that only 7 days this entire summer have been below the seasonal average.{} In June, there were just four - on the 13th, 14th, 15th, and 20th; in July, just three - on the 14th, 15th, and 16th; and this month, there have been none.{} The prospect of rain and the attendant cooler temperatures could{}yet add some below average days to our August tally, starting with today.{} With a fair amount of cloudiness, highs today should be in the low to mid{}80s; that milder trend should continue through much of next week.

      Look for some scattered showers today, the possiblily of{}heavier showers tonight and tomorow, and perhaps some more rain on Monday.{}{}But the return of high pressure on Tuesday will{}bring lower humidity, sunnier skies, and more pleasant days for the bulk of the week.{} With the dip in temperatures, the shortening of the days, and{}a slight decrease in the intensity of the sun's rays,{}signs that September is not that far away are all around us!{} Enjoy your weekend.
