The diurnal range of temperature was fairly low for the entire week and was 12 degrees on three straight days. Conditions were mostly cool and damp with the high for the week only reaching into the mid-50s with measurable rain on 5 of the 7 days. A coastal low developed towards the end of the week, and brought with it nearly an inch and a half of rain.
