Taken earlier tonight, this is a quick iPhone shot of the north edge of an orange grove showing the temperature station we watch. At 3:15 am here, the temperature is at about 32° F. At this point, this is about 5° lower than forecast. With several hours to go until daylight, it could dip into the upper 20’s. Consequently, it looks like we’re going to have more frost than expected in citrus in our area, but that could change by morning. Irrigation pumps are being started now and based on the conditions, that should do a good job of protecting the young flowers, fruits and flush from frost damage. Updates after the jump.

Update  Frost at morning was mostly on ground level. The rapid drop in temperature right after midnight leveled off, so the conditions conducive to frost moderated and we slipped by again.
