Excessive Rainfall Potential for the Southeast; Heat Expands for Center of the Nation; Critical Fire Weather for Pacific Northwest

Flash flooding threatens areas from the Tennessee Valley to the Carolinas as storms repeat along a stalled front. Monsoonal storms may trigger flooding in the Southwest. Dangerous heat expands across the Desert Southwest, Plains, mid-Mississippi Valley and Southern Tier. Critical fire weather for interior Pacific Northwest. Cooler, drier air brings brief relief to the Great Lakes and Northeast. Read More >

So we are about a month out from when the snowpack reaches its normal peak depth and theoretically should contain the most liquid or snow water equivalent (SWE). The normal date for this peak in Colorado is April 9th and in Utah April 4th but the actual peak date varies in any given water year.

This time series graph of snowpack for Colorado shows the current (dark blue) state of the SWE compared to normal (red) and 2017 (blue). As of March 5th the snowpack in the State of Colorado was 69% percent of normal and 52% of what it was on this date in 2017.

Here is a similar graph for Utah, again not a lot of good news.

Below is a visual map of SWE made using ground, airborne and satellite data comparing the snowpack of the past two years on March 5th.
