NASA SPoRT has developed a real-time configuration of the NASA Land Information System (LIS) that runs over much of the central and eastern United States at 3-km grid spacing. The LIS produces several products, including a suite of soil moisture products that can be used to help assess drought and flooding potential. WFO Raleigh is pleased to be participating (along with WFOs Houston and Huntsville) in an assessment of these products from August through October.
Central North Carolina has been in a short-term relative dry spell of late, with much of the area having seen little to no rainfall in the last week (Fig. 1). One ramification of this lack of rainfall is the soil drying evident in the 1-week difference in column relative soil moisture imagery (Fig. 2), which shows marked drying over all of Central NC in the last week. Interestingly, in coastal sections of NC that actually have seen some rainfall in the last week, the soil drying has been even more pronounced. Reasons for this are unclear, but it may have to do with the soil type over Eastern NC.
