So far this month, 11 out of 18 days have seen rainfall, with 4 of those days having rainfall totals over an inch.  It appears we can add at least one more day to the rain list as Tuesday brings with it a good chance for showers with a clipper-like system that swings through.   We shouldn't see any flooding rains of any kind, but moderate rainfall will be likely as up to a quarter of an inch can be expected.  Wednesday, this upper low to the north over Canada will continue to rotate around and around and bring with it another chance for a few showers in the afternoon.  This appears to be due to the cooler air in the upper levels of the atmosphere and warmer temperatures at the surface due to increased surface heating from the sunshine to create instability showers later in the day.  Instability showers by definition are episodes of convective precipitation falling in an area no more than about 10 km wide and for a time period of less than about one-half hour.

What about the remainder of the week you ask me...  When will it get NICE!  Well hold your horses, because we are going to have to wait for the weekend.  The Memorial Day Weekend to be exact.  We can at least live with the partly cloudy skies and cool temperatures near 70 degrees Wednesday through Friday, but we have to wait for the reallllly nice weather come Saturday through Monday.  Sunny skies and warming temperatures are expected with low 70s expected Saturday, upper 70s expected Sunday, and lower 80s expected Monday.  I must say though, living in DC my whole life and going through Memorial Day and Labor Day weekends alike year after year, I will keep my eyes on this weekend, as it seems to be cursed with the appearance of clear skies early in the week, then raining when we get to it.  Don't worry, I've got you covered!!!
