This week's soil moisture map could be called "A Tale of Two States" if Dickens were the one producing it. The eastern quarter of the state (i.e., east of Highway 81) is generally sufficiently moist with all sites reporting an SMI above 0.0 and therefore, some surplus of soil water remaining. The forecast also looks favorable for 1-2" of rain over the next week and with temperatures remaining well below 90 in that time, this region is expected to stay relatively moist. However, it should be noted that most of the sites in this region *need* to get a decent rain to keep the surplus, as only Firth and Concord have surpluses greater than an inch. 

 

West of Highway 81 conditions look much worse. As noted on last week's Drought Monitor, portions of south central, southwestern, and the western corner of northeast Nebraska are now considered to be abnormally dry(D0). This week's report does nothing to conflict with that assessment. Most sites in the abnormally dry region are now reporting SMI values lower than -2.0 and the number of sites with a deficit of greater than 0.75" has crept up to 10. The driest locations are around McCook in southwest Nebraska, around Cozad in central Nebraska, and up in Antelope County (Brunswick and Elgin). There are pockets of moisture in western Nebraska (e.g., Curtis) but those locations are definitely the exception to the rule now.

 

The good news is that the WPC forecasts an inch or more of rain for much of the state, so perhaps this week could be the low point in the growing season. However, if that doesn't pan out, most areas can expect their deficits to go up, or in the case of some eastern Nebraska sites, go into deficit for the first time this season.  

 

  

** The Soil Moisture Index (SMI) is based on the estimated field capacity and wilting point at three depths (10 cm, 25 cm, 50 cm) at Automated Weather Data Network (AWDN) sites under grass cover. The index may not necessarily be representative of conditions of a nearby field, particularly if differences in total precipitation over the previous week have been significant. **
