The month of June 1998 was much warmer and much drier than normal. Though not the warmest June of record, June 1998 did finish in third place. This was behind June 1925 when the temperature averaged 86.4, and June 1901 when the reading averaged 86.6 Compared with June 1997, June 1998 was 7.7 degrees warmer and 3.60 inches drier. Rainfall through June 30 was 10.60 inches less this year than last. Showing the impact of the past three months' drought, rainfall over the past 12 months has dropped to 92 percent of normal. Rainfall since mid-March is now about 20 percent of normal. The thirty-day outlook had called for above normal temperatures and below normal precipitation.
The first week in June saw temperatures average four degrees above normal and rainfall about 200 percent of normal. Readings were hot through the 4th, but cooled to much below normal levels on the 6th and 7th. A major storm crossed on the night of the 4th-5th, with widespread reports of wind damage. It brought the week's rain.
The second week in June saw temperatures seven degrees above normal and no rainfall. Surface and upper atmospheric high pressure dominated the region's weather. With storm features kept on a track through the Central Plains, East Texas received no significant rainfall. The heat continued during the third week in June, with temperatures running nine degrees above normal and there being no rainfall. Upper atmospheric high pressure remained the dominant weather feature.
Temperatures warmed gradually until the 19th, and lowered gradually after that as temperatures in the lower levels of the atmosphere dropped slightly.
The final nine days of June saw temperatures run eight degrees above normal, and again there was no rainfall. A minor tropical disturbance brought widely scattered showers on the afternoons of the 28th and 29th, but there was no measurable rainfall in Tyler. The upper air high pressure feature remained dominant.
