Rain and a storm system developing offshore helped deliver us the coolest day of the month so far. We only had to wait until the 23rd! Highs in the mid-40s are a good 10 degrees or more below average for the date. The rawness of today wanes somewhat tonight as rain ends. Sun returns tomorrow before the next rainmaker heads our way.

Through tonight: Rain is largely over, but a shower or two is possible into the first part of the evening. Otherwise, a few breaks should develop in the clouds. Lows settle to the mid-30s in the cool spots to the low 40s in the warm. Winds blow from the north around 5 mph.

Tomorrow (Tuesday): We should see at least some sun. How much is certainly up in the air. For now, it seems the best odds for it are in the midday, before clouds from the next storm system approach. Highs range from the mid-50s to near 60. Winds are out of the north around 10 mph early, switching to the east with time.

Cold! CWG’s Jason Samenow reminded me that today was the first day of the month that the high temperature did not reach 50 degrees. 2020 was in the running to be the first March on record without a high cooler than that, but it could still end up tying 1977, which had only one such day below 50 as well.
