Discussion              

With high pressure situated just off the coast, the weather around here will remain pretty pleasant for the next couple of days with sunshine each day and mild conditions.  Weak low pressure near the Mid-Atlantic coastline on Thursday will bring us plenty of clouds and a good chance of showers.  Very mild weather will close out the work week with highs on Friday likely near the 70 degree mark. Showers on Friday night and Saturday will signal the arrival of cooler air for the upcoming weekend.

One final note, you may have noticed some purplish sunsets (and sunrises) in recent days and weeks. This is still the result of the Tonga volcanic eruption that took place back in January. Fine volcanic aerosols in the stratosphere scatter blue light which, when mixed with ordinary sunset red, produces a violet hue. The purple color is often preceded by a yellow arch hugging the horizon. As the sun sets, violet beams emerge from the yellow, overlapping to fill the western sky with a soft purple glow.
