THE THREE MONTH OUTLOOK FOR MARCH...APRIL AND MAY SHOWS A GREATER
THAN EQUAL CHANCE OF ABOVE NORMAL TEMPERATURES ACROSS THE
SOUTHEAST CORNER OF WYOMING. THE REST OF WYOMING HAS EQUAL
CHANCES OF ABOVE...BELOW...OR NORMAL TEMPERATURES. THE
PRECIPITATION OUTLOOK FOR THIS THREE MONTH PERIOD SHOWS A BETTER
THAN EQUAL CHANCE FOR BELOW NORMAL PRECIPITATION ACROSS THE
SOUTHWEST TWO-THIRDS OF THE STATE. THE NORTHEAST THIRD OF WYOMING
HAS EQUAL CHANCES FOR ABOVE...BELOW OR NORMAL PRECIPITATION OR NO
SIGNIFICANT CLIMATE SIGNAL.
