A cold front, which was accompanied by very dark threatening clouds yesterday, produced nothing more than a few light showers and nothing here at the summit. Winds shifted from SSW to NW, but peak gusts only reached around 25 mph. During last evening we received 0.10 inch as a total of three hours worth of light rain. Today’s temperatures are generally reaching only the 50’s after an early morning low 41F, which was 3 degrees above the normal for this date. After dew points rose through the 50’s to near 60 degrees preceding the cold front today’s air mass is much drier with dew points holding mostly in the upper 30’s. Today’s Observations: 7 A.M.
