Saturday was not only a good-looking day, but also the warmest day this month of May.The mercury hit 83 at Reagan National under mostly sunny skies and the comfortable humidity levels made for a spectacular day. Today will be similar, if a bit less sunny and a bit more humid.  High clouds and a southerly flow should send temperatures into the mid to upper 80s. Today will set the pattern for what looks to be a string of increasingly warmer and more humid days stretching into the coming week. Expect daytime highs in the mid to upper 80s with high dewpoints. As that warmer and stickier air from the south arrives and a cold front stalls to our north, conditions will be ripe for occasional showers and thunderstorms throughout the period.  With a series of low pressure systems likely to pass along that front through the week, mostly sunny days will also be very unstable ones with downpours possible through week's end. Temperatures are expected to cool to the lower 80s by the start of the Memorial Day holiday weekend.

NOTE: With the sun and warmth come increased levels of ultraviolet radiation - the UV index was in the "very high" range yesterday - and irritating pollen counts. But these late spring days also feature the heady aroma of honeysuckle and the fresh green on new leaves everywhere. Even the weeds don't look half bad! Enjoy your Sunday.
