Light to moderate snow will continue into Saturday over the Great Lakes, Central Appalachians, and Northeast. This weekend into next week, a series of atmospheric rivers will bring gusty winds, periods of heavy rain, and mountain snow to northern California and the Pacific Northwest. Colder temperatures are in store for the weekend from the Great Lakes to East Coast. Read More >
The above image is a high-resolution map of drought conditions in Michigan as delineated in the U.S. Drought Monitor, which is released every Thursday morning.
Below is a list of links that highlight different products that may be of interest for monitoring drought conditions.
Drought Monitors/Indices:
U.S. Drought Monitor A national map showing drought intensity and impacts, produced in collaboration by the National Drought Mitigation Center (NDMC), the Climate Prediction Center (CPC), and the National Climatic Data Center (NCDC), among other agencies.
https://droughtmonitor.unl.edu/
North American Drought Monitor Similar to the U.S. Drought Monitor, this is issued monthly for the United States, Canada, and Mexico.
https://www.ncdc.noaa.gov/temp-and-precip/drought/nadm/maps
Palmer Drought Index One of the major indices used when monitoring drought conditions, taking into account rainfall, temperature, and historical data. NOTE: This index is issued for climatic zones, of which the Upper Peninsula only has two.

Crop Moisture Index Based on the Palmer Drought Index, the CMI is designed to monitor short-term moisture conditions affecting develop crops. NOTE: This index is issued for climatic zones, of which the Upper Peninsula only has two.

Standardized Precipitation Index Developed in 1993, the SPI is an index based on the probability of precipitation for any time scale. The SPI can be computed for different time scales, can provide early warning of drought and help assess drought severity, and is less complex than the Palmer.

Experimental Objective Blends of Drought Indicators The short-term blend approximates drought-related impacts that respond to precipitation (and secondarily other factors) on time scales ranging from a few days to a few months, while the long-term blend approximates drought-related impacts that respond to precipitation on time scales ranging from several months to a few years.

Observations:
Precipitation Monitoring Included are links for 30, 90, 180, and 365 day periods, with graphics showing precipitation, precipitation anomalies, percentage of normal, and normal precipitation totals on a national scale.
http://www.cpc.ncep.noaa.gov/products/Global_Monsoons/gl_obs.shtml
Precipitation Analysis Included are graphics for last 1, 7, 14, 30, 60, 90, and 180 days, month to date, and year to date rainfall, as estimated by radar. You may view observed, normal, departure from normal, and percent of normal graphics. Clicking on Michigan while viewing the national map will zoom in to the state level.
WARNING: Due to blockage of radar beams by the Huron Mountains, values near Big Bay and along the Keweenaw Peninsula are lower than the actual accumulation received.

U.S. Soil Moisture Monitoring The “Soil Moisture” bullet (second from the top) leads to graphics showing soil moisture, soil moisture anomalies, soil moisture percentiles on a daily, monthly, and yearly basis.
