Verification for Philip, SD

Forecast for Saturday, July 5th:
NWS Forecast: Fri morning 99F, Sat. morning 96F
My Forecast: Fri morning 96F, Sat. morning 95F
Rainfall forecast: None
Actual High: 90F
Actual Rainfall: None
Temperature Difference: 5 degrees

Why the temp error? Cloudiness in the morning held back the high before the cold front moved through. Once the cold front did move through Philip it cleared up, but 850 mb temps had dropped considerably, not allowing for the high to break 90F. It was expected that 850 mb temps would drop, but not as substantially as occured, thus the high was not able to get back up into the mid-90s. Pine Ridge, SD (40 miles south) reached 94F yesterday.

Forecast for Sunday morning low:
NWS Forecast: 63F
My Forecast: 63F
Rainfall forecast: 0.05 inches
Actual low: 65F
Actual Precip: 0.04 inches
Temperature Difference: 2 degrees

My Total Difference: 7 degrees
NWS Difference: 8 degrees
