For information on "Weekly Weather & Crop Bulletin" call Mark E. Miller at (202) 720-7621, office hours 7:00 a.m. to 4:00 p.m. ET. National Weather Summary Volume 86, No. 11 March 7 - 13, 1999 For additional information, call (202) 720-7917. Highlights: Two major storm systems delivered much-needed precipitation to the central and southern Plains, significantly improving soil moisture for hard red winter wheat. Rain also fell across the Southeast, improving pre-planting moisture. Weekly rainfall topped 4 inches in the Arklatex and central Gulf Coast regions. Mostly dry weather persisted, however, across extreme southern and western Texas and most of the Southwest. At week's end, heavy snow blanketed a narrow band from southeastern Colorado, western Kansas, and northern Oklahoma to the Ohio Valley. The snow insulated winter wheat against post-storm temperatures that dropped below 10 degrees F in some areas. Temperatures also dipped below 10 degrees F from the upper Midwest to the Northeast, following earlier snowfall. In fact, much colder weather prevailed nearly nationwide, slowing or halting winter grain development. Temperatures were not low enough across the South, however, to harm winter wheat, fruit tree blooms, or newly planted spring crops. Nevertheless, weekly temperatures averaged 4 to 10 degrees F below normal on the central and southern Plains, ending an 8-week warm spell, and as much as 15 degrees F below normal in the eastern Corn Belt. Temperatures remained below 40 degrees F for the entire week in most of the Corn Belt. Readings were as much as 6 degrees F below in California, slowing fieldwork and perpetuating a 7-week cool spell. Early in the week, very cold weather gripped the Great Lakes and Northeastern States, especially in deeply snow-covered areas. On Sunday in Michigan, daily-record lows included -6 degrees F in Flint (with a 10-inch snow depth) and -13 degrees F in Lansing (7-inch depth). A day later in New York, Rochester-- with 31 inches of snow on the ground--logged a March record-tying low of -7 degrees F (previously achieved on March 5, 1872, and March 13, 1885). Elsewhere in northern and western New York, lows on March 8 dipped to -18 degrees F in Watertown and -20 degrees F in Angelica. On March 8-9, heavy snow fell in a narrow band from the upper Midwest to the Mid-Atlantic region. Minneapolis, MN netted 16.0 inches, including a daily-record snowfall (12.5 inches) on Monday. Elsewhere, storm-total snowfall reached 11.8 inches in Chicago, IL, 11.3 inches in Des Moines, IA, 7.8 inches in Dayton, OH, and 7.1 inches in Ft. Wayne, IN. In Washington, DC, storm-total snowfall of 8.4 inches accounted for 74 percent of their season-to-date total. In the snow's wake, March 11 temperatures in West Virginia fell to daily-record levels at Parkersburg (11 degrees F) and Elkins (-2 degrees F). Farther south, rain spread eastward from the central and southern Plains, although wet snow and sleet was reported as far south as the southern Appalachians. Significant precipitation returned to the central and southern Plains on March 12-13, leaving only portions of western and southern Texas unfavorably dry. In Kansas, storm-total snowfall reached 17.4 inches in Dodge City, 9.7 inches in Goodland, and 8.1 inches in Wichita. Prior to the storm, season-to-date snowfall in Wichita stood at 1.2 inches. On the Ozark Plateau, March 12-14 snowfall totaled 23.0 inches in Cassville, MO and 14.3 inches in Springfield, MO. Most of Springfield's snow (14.0 inches) fell in a 24-hour period on March 13-14, their second-highest March total behind 15.7 inches on March 16, 1970. The largest storm total in northern Oklahoma, 19 inches at Medford, ranked as the fourth-highest peak snowfall for any storm in the State, trailing events on February 21-22, 1971 (36 inches in Buffalo), November 25, 1992 (22 inches in Laverne), and March 16, 1970 (20 inches in Bartlesville). We 1 (3-99) Farther south, daily-record rainfall occurred on Friday in Oklahoma City, OK (1.81 inches) and Wichita Falls, TX (2.87 inches). A day later, Oklahoma City received 1.3 inches of snow. Through March 14, month-to-date rainfall reached 3.93 inches in Wichita Falls, 4.11 inches in Baton Rouge, LA, 4.34 inches in Meridian, MS, and 5.02 inches in Montgomery, AL. In Florida, 1.72 inches of rain dampened Tallahassee on March 14, boosting their year-to-date rainfall to 8.99 inches (67 percent of normal). In Miami, FL, however, February 1 - March 14 rainfall remained well below normal, at 0.50 inch (16 percent of normal). Similarly, year-to-date precipitation reached 0.66 inch (16 percent of normal) in San Antonio, TX, 0.57 inch of which fell during the late-week period. No measurable rain fell during the storm in Midland, TX, leaving their 1999 total at 0.33 inch (25 percent). Dry weather also continued in Tucson, AZ, where measurable precipitation fell only once (0.01 inch on January 26) during the 98- day period from December 7 to March 14. In contrast, October 1 - March 13 precipitation surged to 104.65 inches (148 percent of normal) in Quillayute, WA, exceeding their previous record of 103.62 inches, set in 1974-75. In Alaska, very cold weather (5 to 16 degrees F below normal, except in southeastern areas) prevailed for a second consecutive week. On Wednesday, daily record-tying lows were noted in McGrath (-36 degrees F) and Barrow (-43 degrees F). _______________________________________________________________________________ Weekly Weather and Crop Bulletin Agricultural Statistics Board March 1999 NASS, USDA National Agricultural Summary March 8 - 14, 1999 Highlights: A winter storm developed in the western Corn Belt early in the week and moved eastward through the Ohio Valley, Appalachian Mountains, and Atlantic Coast States late in the week. As it moved eastward, the storm delivered a mixture of precipitation, including a wide swath of heavy snow from the Corn Belt to the Atlantic Coast. In the lower Mississippi Valley and adjacent areas of the Great Plains and Southeast, the storm soaked soils with heavy rains. In eastern Texas, the wet conditions halted fieldwork, but improved soil moisture supplies, aiding germination of recently planted corn, cotton, and sorghum crops. The rain also aided winter wheat development in most areas of the southern Great Plains until late-week, when colder weather arrived and hindered vegetative growth. In Oklahoma and the central Great Plains, snow rejuvenated soil moisture levels and curbed insect activity. Most of Florida and the southern Atlantic Coastal Plains remained in a dry pattern. Temperatures averaged well below normal in the Southeast, but freeze damage to fruit crops was minimal. Cool, dry weather continued in the Southwest, and cool, wet weather persisted in the Pacific Northwest. In California, field activities continued with no significant delays and small grains, winter forages, alfalfa, and sugar beets continued to rapidly grow in most areas. Crops in the Sacramento Valley were recovering from excessive wetness. In the Rocky Mountains and across the northern Great Plains, temperatures averaged near normal with scattered snowfall. _______________________________________________________________________________ Weekly Weather and Crop Bulletin Agricultural Statistics Board March 1999 NASS, USDA The next "Weekly Weather and Crop Bulletin" report will be released at 12:00 p.m. ET on March 23, 1999.
