2/14/2018 6:00 PM 0.07 M M M M Rain was very light and spotty until about 2:30 pm when it became continuous. It is still raining lightly at observation time.
2/15/2018 6:00 PM 1.34 M M M M Steady rain all day long, and still drizzling a bit. I'll look over the rainfall rate data tomorrow and edit this report if there are significantly heavier periods of rain.
2/16/2018 6:00 PM 0.37 M M M M This was a rather long duration rain event. Typically we get convective showers with definite start and stop times. This event was characterized by periods of light to moderate rain with longer periods of drizzle in between. I have 5 minute resolution tabular data containing each .01 bucket tip and an estimate of rainfall rate based on time between tips. I've looked at the data and there were some long periods where the rain might have stopped. But I would say generally that some sort of rain has been falling since 2/14/18.
2/17/2018 6:00 PM 0.03 M M M M Tail end of a very good rain event.
2/18/2018 6:00 PM 0.08 M M M M Some convective showers this afternoon in our pre Pacific trough moist environment. One heavy shower produced a rainfall rate of 1.43 inch/hour at 5:15 pm.
