SPECIAL REPORTS

Status of the Screw-worm in the Southwest. (p. 558).

Reports in this issue are for week ending May 22 unless otherwise indicated,

WEATHER OF THE WEEK ENDING MAY 25

Warm, sunny days brought the hottest week of the growing season to date. Rain-
fall was limited to a few areas of scattered showers.

TEMPERATURE: Though the Pacific Northwest continued cool, temperatures averaged
substantially above normal in most other areas. Midperiod maxima soared to 100°
levels in the central and northern Plains StateS boosting averages in these areas
to more than 12° above normal. Kansas had 6 days of 90° or higher. East of the
Mississippi, 2 or more days of 90° heat pushed averages to 6° above normal from
the central Mississippi Valley into southern New England. Many stations from
the Rocky Mountains to New England set new daily records and the mercury hit new
early season maxima at some locales. On the 21st, while new lows for the date
were set in Michigan and Vermont, Fargo, North Dakota, and International Falls,
Minnesota, recorded new early season marks of 98° and 95°, respectively. A new
May high of 98° was logged at Marquette, Michigan. The weekend brought record
heat to the Northeast as 90° readings were observed in northern New England.

RAINFALL: Dry weather prevailed over most areas of the Country. Warm air, long
sunny days, and brisk winds in many of the main agricultural areas east of the=
Rockies further depleted moisture supplies. Brief shower periods late in the
week, brought totals to over 1 inch at many stations from Lake Superior through
western Missouri. Frequent showers over the coastal plain and lower Rio Grande
Valley of Texas gave weekly amounts over 1 inch; some totals exceeded 5 inches.
General showers early and late in the week deposited 0.5-1 inch amounts from
northeast Ohio through northern New England. Heavy showers after midweek wetted
the southeast coast of Florida with 2- to 4-inch falls.

DRY WEATHER: The principle dry area east of the Mississippi is found over South
Carolina and Georgia where little or no rain has fallen in 3 weeks. Over the
Country, the most striking deficiency is found over central and eastern New
Mexico and parts of west Texas including the Panhandle, Amarillo, Texas, has
had only 0.14 inch in the last 17 weeks; Roswell, New Mexico, only 0.17 inch in
15 weeks; Midland, Texas, a trace in the last 9 weeks.

OTHER ITEMS: Severe storms dropped golf ball size hail in Stillwater, Minnesota,
on the 18th, pelted areas in northern Vermont and near Cleveland, Ohio, with
0.75-inch stones on the 19th, and caused extensive hail damage to cars and crops
in Hampton County, South Carolina. On the 22nd, a tornado dipped into a Nebraska
field, while another hit Marion, Minnesota, on the 23rd. (Summary supplied by
U.S. Weather Bureau).

worm flies was released: 31,540,250 in Texas, 492,000 in New Mexico and
62,381,800 in Mexico. The following is a comparison of specimens reported during
corresponding weeks in 1962 and 1963:
