Conditions for the week of Jan. 4-10
Little or no precipitation fell during the week in most areas as well below normal temperatures dominated the weather in the Midwest. Fortunately much of the region has adequate moisture and surpluses, with abnormal dryness (D0) and drought limited to a few small D0 areas in the Ohio Valley and D0-D1 in Missouri and southern Iowa. In western Ohio and eastern Indiana, however, enough precipitation (0.5-1 inch) fell on the D0 area that short-term deficiencies were negated in most locations. Farther west, 0.2-0.4 inches of precipitation maintained the D0 in central and southern parts of Indiana and Illinois. In Missouri, however, little or no precipitation this week and subnormal precipitation during the past three months (extending southwestward into the south-central Great Plains) has accumulated deficits of 4-8 inches, with Standardized Precipitation Indices (SPIs) at severe to exceptional drought (D2-D4) levels out to four months. USGS stream flows have also dropped into the lower 25th percentile across most of the state. As a result, moderate drought (D1) was greatly expanded in Missouri to cover the largest deficits and most negative SPIs.
