Every month, the San Francisco Fed estimates Weather-Adjusted Change in Total Nonfarm Employment (monthly change, seasonally adjusted). They use local area weather to estimate the impact on employment.
The BLS reported 916 thousand jobs were added in March.
The San Francisco Fed estimates that weather adjusted employment gains were 812 thousand; about 100 thousand lower than the BLS reported.
This reverses the impact of weather on the February report, and was expected. This was especially evident in construction were there were 56 thousand construction jobs lost in February, and 110 thousand construction jobs added in March.
