With a high pressure system currently camped over Utah, it appears the 1987-88 water year will end at midnight Friday as the fifth driest in the state's 114 years of recorded weather data.

Since last Oct. 1, the airport recording station of the National Weather Service has registered just 9.94 inches of precipitation. Normal is 15.31 inches.William J. Alder, meteorologist in charge of the National Weather Service's Salt Lake office, said pleasant autumn weather is in store through Tuesday when the high pressure system is expected to begin breaking up. Highs should range between the low 70s and low 80s over the weekend. Lows should be in the 40s.

Alder said it is critical for Utah to receive normal or near normal precipitation in the coming water year because of low reservoir storage and depleted groundwater aquifers.

The 90-day forecast for Utah shows precipitation will be about normal statewide. Temperatures for the western part of the state will be near normal but are expected to be below normal in the eastern areas.
