Degree Days above 32°F (DD_{32}) 
TODAY'S DD_{32}: 5
18DAY CUMULATIVE DD_{32}: 94
DD_{32} is calculated as: DD_{32} = T_{MAX}  32
18day Cumulative DD_{32} is the sum of DD_{32} for the last 18 days.

Precipitation at Paradise 
DAY 1: 0.06 in
DAY 13 (P_{3}): 0.92 in
DAY 415 (P_{15}): 5.80 in
18DAY TOTAL (P_{18}): 6.72 in
PRECIP THRESHOLD A (P_{A}) EXCEEDED: True
P_{3} > (0.67 * P_{15} + 2.5)
PRECIP THRESHOLD B (P_{B}) EXCEEDED: True
P_{3} > (0.67 * P_{15} + 4.5)

Snow at Paradise 
DEPTH: 130 in
SWE DAY: 28
CALCULATED SNOW DENSITY: 378.37 kg/m^{3}
CALCULATED SWE: 49.36 in
SWE Day, Calculated Snow Density, and Calculated SWE based on work by Sturm and others (2010)
If T_{avg} > 32°F, snow melt is factored in at: M (in) = a(T_{avg}  T_{32}), where a is between 0.0766  0.1312 in * °F^{1} * day^{1} (Currently 0.1039) and T_{32} = 32°F. This method is from Westerstrom (1982) in Kustas and others (1994) and converted to US customary units.

Seasonal Variables 
DAYS SINCE JULY 11: 145
July 11 is the average snow meltout day (where snow depth goes down to 0 in) at Paradise

Calculated Variables 
D_{0}: 3
D_{1}: 3
D_{2}: 1
D_{3}: 3
D_{4}: 1
D_{5}: 2
HS_{dry}: 10.5
These are primarly for the Dryweather debris flow hazard model, but calculated every day.
HS_{dry} = (([D_{0} + D_{1} + D_{2}] * D_{3}) * D_{4}) / D_{5}
See model (right) to figure out how D_{0}  D_{5} are calculated.
