Downward Temps from Monday

Posted: 18 Mar 2015 05:41 AM

After reaching the 80s on Monday, our highs on Tuesday were much cooler in the 50s. The featured map displays the maximum negative change in 24 hour temperature. This metric was computed by subtracting the hourly HRRR model analyses from their respective analyses from 24 hours previous and then computing the maximum negative change per model grid cell. Most of the largest differences show up over the high plains with changes approaching 50 degrees. Our largest changes were in the 30 to 40 degree range.

Good = 25
Bad = 4
Abstain = 6
