<x-flowed> BLUE HILL METEOROLOGICAL OBSERVATORY, MILTON, MASSACHUSETTS 02186 ELEVATION 635 FT. ABOVE MSL....10 MILES SSW OF BOSTON, MA FRIDAY JULY 12 2002 PLEASE VISIT OUR WEB SITE AT: http://www.bluehill.org/ SEE OUR NEW OFFICE CAM FACING WEST OUT WEST WINDOW AT www.bluehill.org/webcam DAILY DISCUSSION... 7/12/2002..2 P.M. The haze and high thin clouds have replaced the beautiful blue skies of the past two days, which obstructs our view of the Monadnock's from the top of the Observatory. Also, we have noticed a slight rise in temperature, yet the mercury still remains below normal. Temperatures continue to remain in the low to mid 70's with pleasant dew points in the lower 50's - A sweet escape of the recent hot weather! The humidity throughout the day continues to remain near 45%. Although we have had beautiful weather so far this July, we could use some precipitation as we remain below normal for the month as well as for the year. OBSERVATIONS TODAY..... 8 A.M.
