Using this tool:
Select a station. (Station locations can be found on the map here
Select a month, season or the whole calendar year.
Select the year (Selecting Dec-Jan-Feb, 2019 creates a report ending Feb, 2019)

Feels Like is temperature adjusted for wind chill and heat index.
Frostdays are days that are at or below 32 °F at least part of the day.
Rain+Snowmelt is graphed with data that is uncertain due to freezing in gray. Snow reporting is delayed until melting and is often underreported due to wind scouring.
Rain days are days with measurable rain or snowmelt (0.01 in or greater).
Deepest Frost is the deepest calculated occurrence of 32 °F in the sod-covered soil profile.
Soil Moisture is in units of volumetric water content (inches of water per inch of soil). Frozen sensors cannot report soil moisture and are gray. Precipitation is plotted above to show percolation. This is a beta product under development.
Max Gust is the fastest 3-second wind.
Max Speed is the fastest 5-minute wind.
Total Possible Solar Radiation is calculated value and is what would be expected with clear skies and no smoke or haze from sunrise to sunset.
Pressure is adjusted for elevation (altimeter setting).
Normals are always provided for the days data is available, not for the days requested; a positive (negative) “From Normal” value indicates that observed values were above (below) normal.
Dates of occurrence are for the last occurrence in the event of ties.
Days are reported midnight-to-midnight local time.
